Big Brother 18 (U.S.)

Season development

On September 24, 2014, CBS announced that it had renewed Big Brother for its 17th and 18th editions for broadcast in summer 2015 and 2016, respectively. The series would continue to be hosted by Julie Chen.

Format

The format has changed slightly from previous seasons. The contestants, referred to as "houseguests," are sequestered in the Big Brother House with no contact to or from the outside world. Each week, the houseguests take part in several compulsory challenges that determine who will win food, luxuries and power in the house. At the start of each week, the houseguests compete in the Head of Household (HoH) competition. The winner of the HoH competition will select two houseguests to be nominated for eviction. Each week, six houseguests are selected to compete in the Power of Veto (PoV) competition: the reigning HoH, their two nominees and three houseguests selected by random draw. The winner of the PoV competition wins the right to either revoke the nomination of one of the nominated houseguests or leave them as is; if the veto winner uses this power, the HoH must immediately nominate another houseguest for eviction. The PoV winner is also immune from being named as the replacement nominee. This season's Have-not room features bumper cars. On eviction night, all houseguests vote to evict one of the two nominees, with the exception of the nominees and the Head of Household, who is only allowed to vote in the event of a tie, in which case they must do so publicly. This compulsory vote is conducted in the privacy of the Diary Room. Unlike most other versions of Big Brother, the houseguests may openly and freely discuss the nomination and eviction process. The nominee with the majority of votes will be evicted from the house on the weekly live broadcast, exiting to an adjacent studio to be interviewed by Chen, after which the cycle begins again. Houseguests may voluntarily leave the house at any time and those who break the rules may be expelled from the house. The last nine evicted houseguests will form the Big Brother jury and vote for the winner during the season finale. The jury members will be sequestered in a separate house and will not be allowed to watch the show except for competitions and ceremonies that include all of the remaining houseguests; the jury members will not be shown any Diary Room interviews or any footage that may include strategy or details regarding nominations.

Teams

Similar to the cliques twist in Big Brother 11, the houseguests initially competed in teams, which were selected by school-yard pick prior to the first competition. When a HouseGuest wins Head of Household, their entire team earns immunity from nominations, while the team with the worst performance in each Head of Household competition became the Have-Nots for the week. Frank, Michelle, Paulie and Bridgette formed Category 4; Da'Vonne, Paul, Zakiyah and Jozea formed Big Sister; James, Natalie, Victor and Bronte formed Team Unicorn; Nicole, Corey, Tiffany and Glenn formed Team Freakazoids. On Day 37, the teams were officially disbanded.

BB Roadkill

Following the nomination ceremony, the houseguests competed in the BB Roadkill competition, with the winner earning the power to privately nominate a third HouseGuest for eviction. For each Roadkill competition, an RV is placed in the backyard; one at a time, houseguests enter the RV to complete the task. Following the competition, the HouseGuests are privately informed if they won or lost the challenge, with no obligation to ever reveal their result; the winner then names a third nominee in the Diary Room. Unlike the Head of Household, the Roadkill winner could nominate a member of his or her own team, provided their intended nominee is not immune. If the Roadkill nominee is saved by the Power of Veto, the Roadkill winner has to privately name a replacement nominee. The power to privately name a third nominee and replacement was previously seen in Big Brother 15 with the MVP, who earned the power through public vote. On Day 37, the BB Roadkill competition was officially cancelled.

Battle Back

Instead of permanent eviction, the first five evicted houseguests received a chance to return to the game. The first two evictees faced off in a duel, with the winner advancing to face the next evicted houseguest, permanently eliminating the losers; following four duels, the remaining evictee will re-enter the house. All four duels aired in a special episode on July 22; Jozea defeated Glenn in the first competition, but Victor defeated Jozea, Bronte and Tiffany in the subsequent competitions to return to the house.

Round Trip Ticket

Shortly after the end of the Battle Back, Teams and Roadkill twists, the houseguests were alerted to the existence of a secret room within the house. To find it, houseguests deciphered a series of clues hidden on decorations throughout the house to uncover a five-digit code, and then dialed the code into a phone booth in the house to reveal a tunnel to the room; only one houseguest was allowed to enter the room at a time. Inside the room was 12 envelopes, and each houseguest could only claim one envelope. Inside one of the envelopes was a "Round Trip Ticket," which would allow the houseguest who picked it to re-enter the house immediately following eviction. Envelopes could only be opened by a houseguest following their eviction; If a houseguest opened their envelope prior to their eviction, their card would be voided. Once all remaining houseguests entered the room and picked tickets, they were free to enter the room with no restrictions. The tickets were valid until Day 65; Paul had the Round Trip Ticket, but was not evicted while the tickets were still valid.

America's Care Package

After Frank's eviction, Julie announced that for the next five weeks, beginning in Week 6, viewers would be able to give one houseguest per week a special power—or "care package"—as determined by a public vote. All five powers were revealed to the public upon the twist's introduction. The houseguests were made aware of this twist, though the weekly rewards were left unspecified until the package was dropped in the backyard for public unboxing. Once a houseguest receives a care package, they are no longer eligible to win future packages.

New HouseGuests

The 12 new HouseGuests were announced on June 14, 2016. Among them are two siblings of former Big Brother HouseGuests: Paulie Calafiore, brother of Big Brother 16 runner-up Cody Calafiore and Tiffany Rousso, sister of Big Brother 17 houseguest Vanessa Rousso.

Returning HouseGuests

This is the fifth season to feature former HouseGuests returning to the game. the first time since Big Brother 14 . The four returning players were announced during the premiere episode on June 22, 2016. As part of the House's travel theme, the returning HouseGuests were referred to as "stowaways," entering the House in suitcases shortly prior to the new HouseGuests' arrival.

Future appearances

Jozea Flores was one of two former Big Brother houseguests included in a public vote to compete in Big Brother: Over the Top, but lost to Jason Roy from Big Brother 17.

Summary

On Day 1, the 12 HouseGuests entered the House. They were then told about the first twist—four HouseGuests would join them and would be forming teams of four. James, Nicole, Frank and Da'Vonne then entered the House again. Paulie revealed his secret of being Big Brother 16 runner-up Cody Calafiore's brother while Tiffany decided to hold out about her sister, Big Brother 17 houseguest Vanessa Rousso, although Da'Vonne already knew Tiffany's secret and planned to use it to her advantage. Some of the new HouseGuests were set on sticking together and running the Vets out of the house while the Vets knew they needed some of the newbies on their side to stand any chance of surviving. Later on, the HouseGuests went outside to form their teams. Frank, Michelle, Paulie and Bridgette formed team Category 4; Da'Vonne, Paul, Zakiyah and Jozea formed team Big Sister; James, Natalie, Victor and Bronte formed team Unicorn; and Nicole, Corey, Tiffany and Glenn formed team Freakazoids. The HouseGuests were then told about a second twist. The four teams will compete in four competitions. The winning team of each competition will be safe and exempt from the next one. The last team remaining will then have to compete against each other as individuals. The loser of the final competition will be evicted from the House. The remaining three will then decide amongst themselves which one of them will be the first Head of Household. The HouseGuests then went outside for the Ride the Rocket competition. Each team must climb onto their rocket and stay on for as long as possible. The team who gets eliminated first will land in "Notburg" and be Have-Nots for the week. The second team to fall will go to "Mystery Land" and receive a mystery punishment. The third team will land in "Cash City" and be given $10,000 to split. The last team will land in "Safeville," which will guarantee the team's safety for the next two evictions. Big Sister became Have-Nots, Category 4 went to Mystery Land and Team Freakazoids received $10,000. Team Unicorn received immunity for two evictions. The three remaining teams battled in the first round of the Hit the Road competition. Three HouseGuests had to hold on to three ropes to suspend a beam. The other HouseGuest would dig in the sand for a puzzle piece, place it on their beam and switch out with a teammate. If a piece falls, they must start over. The first team to build their fifteen-piece sandcastle and hit their buzzer will win round one. Category 4 won the competition. Team Freakazoids and Big Sister then went head-to-head to build a sandcastle puzzle. The first team to complete the puzzle will win round two. Big Sister won the competition. Team Freakzoids then went head-to-head in the final round of the Hit the Road competition. Each HouseGuest will stand on a tilting island with the letters "SOS." The must climb up their palm tree, grab a coconut, and place it on one of the empty spaces of the SOS. The last HouseGuest to finish their SOS and grab the flag will be evicted from the House. On Day 2, Glenn lost and was evicted immediately.

Immediately after Glenn's eviction, the remaining members of Team Freakazoids decided Nicole should be Head of Household, much to the dismay of the other newbies, who were so comfortable with their numbers, they had no problem telling the Veterans after this week everyone will be after them. Da'Vonne informed Nicole on this and Nicole decided to make a move to target Jozea, the person Da'Vonne felt was the most vocal in the Veteran revolt. Da'Vonne convinced Nicole to nominate Paulie as a pawn to ensure Jozea's eviction. Not surprisingly, on Day 7, Nicole followed Da'Vonne's advice and nominated Jozea and Paulie for eviction, with Jozea as the target. In order to gain the numbers, the Vets pulled in Zakiyah, Michelle, Corey and Tiffany to form the "8 Pack" alliance. Big Brother revealed a brand new competition to the HouseGuests called the "BB Roadkill" competition, which will allow the winner to secretly name a third nominee. The HouseGuests then went outside to the Big Brother RV for the Take It Off Roadkill competition. In this competition, HouseGuests competed individually. They had to strip off their clothes while holding down three buttons while driving the RV. If a HouseGuest releases one button, their timer will go 30 times faster; release two buttons and their timer will go 60 times faster; release all three and their timer will go 120 times faster. The HouseGuest that hits their buzzer with the fastest time will win the competition. Frank was the winner. Natalie, Bridgette and Bronte formed the "Spy Girls" alliance. However, the alliance was made in full view of Tiffany, who informed the 8 Pack of this alliance. As a punishment for landing in "Mystery Land" on the Day 1 competition, team Category 4 had to wear pixelated costumes for the entire week. At the Roadkill Ceremony, Frank secretly nominated Paul for eviction. On Day 10, Nicole, Jozea, Paulie and Paul, as well as Corey and Da'Vonne, with Michelle hosting, barked in the Dizzy Dog Power of Veto competition. In this competition, HouseGuests must swirl around on their stand 15 times to earn 45 seconds. They can then use this time to begin stacking dog treats on top of their dog house. If they don't get back on their stand and resume spinning before their 45 seconds are up, they will be eliminated. The first HouseGuest to stack all forty treats on top of their dog house and hit their button will win the Power of Veto. Paul was the winner and, on Day 12, took himself off the block, forcing Frank to secretly name Bridgette as the replacement nominee. On Day 16, Jozea was evicted by a 7-4 vote, with Bronte, Natalie, Paul and Victor voting to evict Paulie. Julie then informed Jozea that he will join Glenn in the "Battle Back." In the coming days, Glenn and Jozea will face off in a duel, with the winner moving on to wait for the next competitor and the loser being eliminated for good. After five HouseGuests have been evicted, the last HouseGuest remaining will earn a second shot in the game.

Following Jozea's eviction, the HouseGuests challenged in the Berry Balanced Head of Household competition. Each team must send one player across one of two beams. They must grab a berry and return it to their station. If a HouseGuest falls, they will be eliminated. The first team to collect 40 berries and retrieve the final blue berry will win the competition. The HouseGuest who retrieves the blue berry will be the new Head of Household. Category 4 won the competition and Paulie became the new Head of Household. Due to collecting the least amount of berries, Da'Vonne, Paul and Zakiyah became Have-Nots for the week. On Day 17, Paulie nominated Bronte and Paul for eviction. The HouseGuests then competed in the 18 Dollas Roadkill competition. HouseGuests competed individually. HouseGuests had to look at a set of ten items of various prices. They must put tags on six items that add up to exactly $18. The HouseGuest who selects the six items and hits their buzzer in the fastest time will win the competition and earn the power to secretly nominate a third HouseGuest for eviction. Victor won the competition. On Day 17, Victor secretly nominated Tiffany for eviction. On Day 18, Paulie, Bronte, Paul and Tiffany, as well as Da'Vonne and Zakiyah, with Corey hosting, analyzed in the Toe-zarks Power of Veto competition. In this competition, HouseGuests had twelve minutes to collect letters one at a time. Each letter has a point value. They then had to take their letters back to their board and spell the best word possible. The HouseGuest who has a correctly spelled word with the highest point value will win the Power of Veto. Paulie won the Power of Veto. On Day 20, Paulie took Paul off the block and named Victor as the replacement nominee. On Day 23, Victor was evicted by a 9-1 vote, with Paul voting to evict Bronte.

Following Victor's eviction, the HouseGuests served in the Kiss My Ace Head of Household competition. In this competition, one HouseGuest from each team had to serve a ball into their court, hoping to land it in the highest numbered slot possible. The HouseGuest with the lowest score in each round will be eliminated. The HouseGuests will then rotate and serve again. If there is a tie, all tied HouseGuests will be eliminated, unless all four players are tied, in which case they serve again. The last HouseGuest remaining will be the new Head of Household. Bridgette was the winner. For being the first team eliminated from the Head of Household competition, Corey, Nicole and Tiffany became Have-Nots for the week. On Day 24, Bridgette nominated Paul and Tiffany for eviction, with Tiffany as the target. The HouseGuests later participated in the Horn Star Roadkill competition. HouseGuests competed individually. In this competition, they were required to listen to a set of horns. They then had to listen to a sequence of eight horn honks. They then had to repeat the sequence by pressing the correct horns. If they are incorrect, they must try again. The HouseGuest who repeats the sequence in the fastest time will win the competition and earn the power to nominate a third HouseGuest for eviction. Frank was the winner. On Day 24, Frank secretly nominated Bronte for eviction. On Day 25, Bridgette, Bronte, Paul and Tiffany, as well as Natalie and Paulie, with Da'Vonne hosting, mixed it up in the Vetolicious Power of Veto competition. In this competition, HouseGuests looked at a sequence of colored ingredients. They then were asked to place a certain ingredient in the pot. If a HouseGuest is incorrect, they will be eliminated. The last HouseGuest standing will win the Power of Veto. Bridgette was the winner. On Day 27, Bridgette decided not to use the Power of Veto. Da'Vonne considered flipping the vote against Bronte and using Tiffany to go after Frank. On Day 30, Bronte was evicted by a 5-4 vote, with Frank, James, Natalie and Paulie voting to evict Tiffany.

Following Bronte's eviction, the HouseGuests were quizzed in the Euro Trippin Head of Household competition. In this competition, HouseGuests were asked questions based on photos of the first three evicted HouseGuests on a European trip. An incorrect answer resulted in elimination. The last HouseGuest standing will be the new Head of Household. Paulie was the winner. For being the first team eliminated from the Head of Household competition, James and Natalie became Have-Nots for the week. Despite being enemies the previous week, Tiffany, Frank and Bridgette formed an alliance after all three were shunned by the rest of the House. On Day 31, Paulie nominated Natalie and Tiffany for eviction, with Tiffany as the target. Later, the HouseGuests freshened up in the Gasping for Air Roadkill competition. HouseGuests must hang air fresheners on their colored pipes. If an air freshener hits the ground, it is out of play. The HouseGuest who hangs the most air fresheners in the shortest amount of time will win the competition and earn the power to nominate a third HouseGuest for eviction. Tiffany was the winner. On Day 31, Tiffany secretly nominated Corey for eviction. On Day 32, Paulie, Natalie, Tiffany and Corey, as well as Da'Vonne and Paul, with Zakiyah hosting, got a sweet tooth in the Scooper Star Power of Veto competition. In this competition, HouseGuests competed in head-to-head matches. In each match, HouseGuests looked at a set of ice cream cones on a monitor. By transferring one ice cream scoop at a time, not setting any scoops on the ground, and only having three scoops on a cone at one time, they must replicate the ice cream cones on the monitor. If they are correct, they will win the round and eliminate their competitor. The last HouseGuest standing will win the Power of Veto. Corey won the Power of Veto. On Day 34, Corey took himself off the block, and Tiffany secretly named Da'Vonne as the replacement nominee. On Day 37, Tiffany was evicted by an 8-0-0 vote. Following Tiffany's eviction, Julie revealed to the HouseGuests that both the team and Roadkill twists were dissolved. Julie also announced to the HouseGuests that the first five evicted HouseGuests competed in the Battle Back competition. Victor was revealed to be the champion of the Battle Back duels and he returned to the House. Julie then revealed a twist to the viewers that would be in play for the next five weeks—in the House, there are secret clues to discover a secret room. Any HouseGuest who discovers this secret room will have the opportunity to claim an envelope. One envelope will hold a round trip ticket. Once a HouseGuest gets evicted, their envelope will be opened. If they have the round trip ticket, their eviction will be null, and they will head back into the House with another shot at the half million dollars.

Following Victor's return, the HouseGuests grooved in the Watch Your Dubstep Head of Household competition. In this competition, HouseGuests had a wristband attached to a confetti box. They must keep their hand above their head while stepping over the light bars that shuffle by their feet. If they drop their hand, their confetti box will open, eliminating them from the competition. The last HouseGuest standing will be the new Head of Household. James was the winner. On Day 38,James nominated Bridgette and Frank for eviction, with Frank as the target. On Day 39, James, Bridgette and Frank, as well as Michelle, Da'Vonne and Nicole, were riddled in the OTEV the Dope DJ Power of Veto competition. In this competition, OTEV asked the HouseGuests a riddle about a competition. They then had to find a record with the name of the competition described in the riddle. The last HouseGuest to return the correct record to OTEV will be eliminated. The last HouseGuest standing will win the Power of Veto. Michelle won the Power of Veto. On Day 41, Michelle decided not to use the Power of Veto. On Day 42, all the HouseGuests solved the clues and discovered the secret room. On Day 44, Frank was evicted by a unanimous 9-0 vote. Frank was revealed not to have the round trip ticket. Julie also revealed another twist to the viewers-- "America's Care Package"—where for the next five weeks, America had the opportunity to vote to send a care package to a HouseGuest. Once a HouseGuest receives a care package, they may not receive a future one.

Following Frank's eviction, the HouseGuests rolled in the Perfect Shot Head of Household competition. Each HouseGuest had a lane with slots numbered 1-21. They must roll their ball down their lane to try and make the highest score. They had the opportunity to practice by rolling their yellow ball down their lane as often as they wanted. Whenever they decided to take their best shot, they must roll the red ball. Whatever slot the red ball lands in will be their official score. The HouseGuest with the highest score will be the new Head of Household. Paul was the winner. For being the bottom four performers in the Head of Household competition, Corey, Natalie, Paulie and Zakiyah became Have-Nots for the week. However, Natalie received America's Care Package, which contained a Never-Not Pass, rendering her immune from being a Have-Not for the rest of the season. On Day 45, Paul nominated Bridgette and Paulie for eviction. On Day 46, Paul, Bridgette and Paulie, as well as Corey, Victor and Natalie, sprinted in the Ready, Set, Whoa Power of Veto competition. In this competition, HouseGuests had to hold down two buttons in their starting lane. At the end of their lanes, a monitor will cycle though the words "ready, set, go." If a HouseGuest releases a button before the word "go", they will be eliminated. Once they see the word "go," they must run to the end of their lane and hit one of the five buttons. The last person to hit a button will be eliminated. Once a HouseGuest uses a button, it is out of play for future rounds. The last HouseGuest standing will win the Power of Veto. Paulie was the winner. On Day 48, Paulie took himself off the block, and Paul named Da'Vonne as the replacement nominee. On Day 51, Da'Vonne was evicted by a 6-2 vote, with Michelle and Zakiyah voting to evict Bridgette. Da'Vonne was revealed not to have the round trip ticket and she became the first member of the jury.

Following Da'Vonne's eviction, the HouseGuests spun in the Harsh Hashtags Head of Household competition. In this competition, HouseGuests stood on a small disc suspended by a hanging rope. As the competition continued, they were spun into insult punching bags. If a HouseGuest falls off their disc, they will be eliminated. The last HouseGuest standing will be the new Head of Household. Victor was the winner. For being the first three HouseGuests to fall in the Head of Household competition, Bridgette, Corey and James became Have-Nots for the week. James received America's Care Package, which contained the power to prevent two HouseGuests from voting at the next eviction. On Day 52, Victor nominated Michelle and Zakiyah for eviction. On Day 53, Victor, Michelle and Zakiyah chose Paulie, James and Nicole for the Hide and Go Veto Power of Veto competition. HouseGuests had three minutes to individually hide their locked veto card in the House. Then, one at a time, HouseGuests entered the House and had one minute to attempt to find a veto card. If a HouseGuest's veto card is found, they will be eliminated, though the owner of the veto cards will not be revealed until the end of the competition. The HouseGuest who hides their veto card the best will win the Power of Veto. Paulie won the Power of Veto, but on Day 55, decided not to use the Power of Veto. At the live eviction, Julie informed the HouseGuests of the Double Eviction. Just before the first live vote, James used his America's Care Package to prevent Corey and Paul from voting. On Day 58, Zakiyah was evicted by a 3-2 vote, with Nicole and Paulie voting to evict Michelle. Zakiyah was revealed not to have the round trip ticket and she became the second member of the jury. Immediately after Zakiyah's eviction, the HouseGuests calculated in the Statcathalon Head of Household competition. HouseGuests were asked numerical questions. HouseGuests were required to state whether the real number was more or less than the number mentioned in the question. An incorrect answer resulted in elimination. The last HouseGuest standing will be the new Head of Household. Corey was the winner and immediately nominated Bridgette and Michelle for eviction, putting the plan to backdoor Bridgette in motion. Corey, Bridgette and Michelle, as well as Paul, Nicole and James, later tussled in the Veto Time Power of Veto competition. In this competition, HouseGuests had to run across their lane into their ball pit at the end. They must search through the balls to find three clocks. They must return their clocks to their stand one at a time. After they retrieve all of the clocks, they must grab their veto symbol above their ball pit and hit their button. The first HouseGuest to hit their button will win the Power of Veto. Corey was the winner, but decided not to use the Power of Veto. On Day 58, Bridgette was evicted by a 5-1 vote, with Natalie voting to evict Michelle. Bridgette was revealed not to have the round trip ticket and she became the third member of the jury.

Following Bridgette's eviction, the HouseGuests went head-to-head in the Hollywoods Squirrels Head of Household competition. In this competition, HouseGuests competed in one-on-one matches. In each round, HouseGuests were asked a question based on a grid of Benny the BB Comp Squirrels. If a HouseGuest buzzes in with the correct answer, they will move on and eliminate their opponent. If they are incorrect, they will be eliminated. The HouseGuest who survives in each round must pick the next two HouseGuests to face off. The last HouseGuest standing will be the new Head of Household. Victor was the winner. For being the first two HouseGuests eliminated in the Head of Household competition, Michelle and Nicole became Have-Nots for the week. Nicole received America's Care Package, which contained safety for the week, on the condition she wear a "Super Safety" costume all week. On Day 59, Victor nominated Corey and Paulie for eviction, with Paulie as the target. On Day 60, Zingbot made an appearance and hosted Victor, Corey, Paulie, Paul, Nicole and James in the Zingbot for President Power of Veto competition, with Natalie moderating. In each round, HouseGuests launched a beanbag at a map to claim votes for Zingbot. Once a spot has been landed in, any future tosses into that spot will have a score of zero. The HouseGuest who gets the least votes in each round will be eliminated from the competition. After each HouseGuest has been eliminated, they will claim a campaign gift. HouseGuests eliminated in future rounds have the option of keeping their gift or claiming a gift already revealed. The HouseGuest with the Power of Veto at the end of the game will win the Power of Veto. Paul became a member of the BB Secret Service, James won $5,000, Paulie must bake apple pies any time he is instructed by Big Brother for the rest of the season, Corey has to wear the "Patriotard" for the week and Nicole won a trip to anywhere in the United States. Victor won the Power of Veto. On Day 62, Victor decided not to use the Power of Veto. On Day 65, Paulie was evicted by a unanimous 5-0 vote. Paulie was revealed not to have the round trip ticket and he became the fourth member of the jury. All of the tickets expired and it was later revealed that Paul had the round trip ticket.

Following Paulie's eviction, the HouseGuests celebrated how far they have survived as they enjoyed a carnival, with a chance to win prizes such as $5,000, a tech-pack containing a new TV, tablet and smart phone, along with a performance from Ziggy Marley. They also picked pies to determine Have-Nots for the week, as well as an advantage in the next Head of Household competition. Michelle, James and Victor became Have-Nots for the week. After the carnival, the HouseGuests blacked out in The Black Box Head of Household competition. In this competition, the HouseGuests entered the black box and held down their button. Throughout the competition, HouseGuests were given opportunities to search the black box for discs. There are also dummy discs that will not fit on their pole. If a HouseGuest does not return to their button before time is up, they will be eliminated. After two hours and ten searches, the player who survives with the most discs will be the new Head of Household. Michelle won the advantage for the competition and she received an extra 30-second solo search. Natalie was the winner. Michelle received America's Care Package, which contained the power of co-HOH. She and Natalie will both have safety, share the HOH room and will each name one nominee. For winning this week's America's Care Package, Michelle's week as a Have-Not was also cancelled. On Day 66, Michelle and Natalie nominated Paul and Victor for eviction, respectively. On Day 67, all HouseGuests except Nicole memorized for the BB Storm Watch Power of Veto competition. In the days leading up to the competition, HouseGuests listened to a series of BB Storm Watch updates. In this competition, HouseGuests competed individually. HouseGuests looked at a teleprompter for sentences with blanks. HouseGuests had to report the weather and fill in the blanks with the name of one of the first five evicted HouseGuests while standing in a storm. If the sentence passes through the teleprompter before the HouseGuest fills in the blank, they will be incorrect. The HouseGuest who fills in the most blanks will win the Power of Veto. Paul was the winner. On Day 69, Paul took himself off the block, and Michelle named Corey as the replacement nominee. On Day 72, Victor was evicted by a 2-1 vote, with Paul voting to evict Corey. He became the fifth member of the jury. Julie then informed the HouseGuests that the jurors will compete in the next Head of Household competition, with one of them returning to the game.

Following Victor's second eviction, the HouseGuests and jurors put it all on the line in the Welcome to Loch Mess Head of Household competition. In this competition, HouseGuests stood on a small platform against a wall. If anyone falls off their platform, they will be eliminated. The last juror standing will be back in the game and the last HouseGuest standing overall will be the new Head of Household. Victor eventually beat out the other jurors to re-enter the game, becoming the first HouseGuest in Big Brother history to return to the House twice in one season. Nicole became the new Head of Household. For being the first two HouseGuests to fall in the Head of Household competition, Corey and Victor became Have-Nots for the week. Corey received America's Care Package, which gave him $5,000 to use to bribe another HouseGuest in the upcoming week. On Day 73, Nicole nominated Michelle and Paul for eviction, with Michelle as the target. On Day 74, all HouseGuests except Natalie tallied in the Santa's Little Counters Power of Veto competition. HouseGuests had a few minutes to count groups of items throughout the backyard. In this competition, HouseGuests were asked how many of a certain object were in the display. After everyone revealed their answer, they had a decision to stay or fold. If a HouseGuest folds, they are ineligible to win a candy cane, but they cannot be eliminated. If a HouseGuest stays and they are the closest to the correct answer, they will win a candy cane. If a HouseGuest stays and they are the furthest away from the answer, then they will be eliminated. The first HouseGuest to get three candy canes will win the Power of Veto. Nicole was the winner. On Day 76, Nicole decided not to use the Power of Veto. Corey used his bribe on Victor in return for him voting out Michelle. On Day 79, after Nicole cast the tie-breaking vote, Michelle was evicted by a 3-2 vote, with James and Natalie voting to evict Paul. She became the fifth member of the jury.

Following Michelle's eviction, the HouseGuests scrambled in the Poached Eggs Head of Household competition. In this competition, HouseGuests had to maneuver eggs through their chicken wire and through their hole. They then had to roll their egg down the ramp in an attempt to knock down the letters "HOH." The first HouseGuest to knock down all of their letters would then become the new Head of Household. Victor was the winner and became the new HOH. For being the last two HouseGuests to place an egg in their special "Have" holder, Natalie and Victor became Have-Nots for the week. However, because Victor won HoH and Natalie had a Never-Not Pass, all of the HouseGuests were safe from being Have-Nots for the week. On Day 80, Victor nominated James and Natalie for eviction. On Day 81, all of the HouseGuests used their resources in the Being Mac Power of Veto competition, sponsored by the new CBS show, MacGyver. In this competition, HouseGuests competed individually. They had to figure out how to escape three different rooms as fast as possible. The HouseGuest who escapes all three rooms in the fastest time will win the Power of Veto, as well as a trip to the set of MacGyver. Corey was the winner, but on Day 83, decided not to use the Power of Veto. On Day 86, Natalie was evicted by a unanimous 3-0 vote. She became the sixth member of the jury.

Following Natalie's eviction, the HouseGuests slid in the Slide-In Theater Head of Household competition. In this competition, HouseGuests had to fill their small scoop with butter, walk down to the end of their slippery lane and pour it into their bowl. If a HouseGuest fills up their small bowl, they will receive a larger scoop. The first HouseGuest to retrieve the ball from their large bowl will be the new Head of Household. Corey was the winner and, on Day 87, Corey nominated Paul and Victor for eviction. On Day 88, the HouseGuests zipped in the BB Comics Power of Veto competition. In this competition, HouseGuests competed individually. HouseGuests had to ride a zip line past the comic studio window to get a look at a set of sixteen comics. They must replicate the comic studio on their computer. However, there are decoy comics with slight differences. The HouseGuest who replicates the studio wall in the fastest time will win the Power of Veto. Nicole was the winner. On Day 89, Nicole decided not to use the Power of Veto. On Day 90, Victor was evicted by a 2-0 vote. He became the seventh member of the jury.

Following Victor's third eviction, the HouseGuests sought a spot in the final three in the What the Bleep? Head of Household competition. In this competition, HouseGuests were shown a series of clips with a censored word or words. Julie will then give them words as to what the blurred phrase may be. The HouseGuests must then state if Julie's suggestion is true or false. A correct answer earned a HouseGuest a point. The HouseGuest with the most points after seven questions will be the new Head of Household. Paul was the winner and, on Day 91, Paul nominated Corey and Nicole for eviction. On Day 92, the HouseGuests recalled in the Cover Your Bases final Power of Veto competition. In this competition, HouseGuests were asked on what day a certain event took place in the House. The HouseGuests had to step on their bases to display the correct day, then hit the umpire to lock in their answer. If they are incorrect, their counter will drop to zero and they must try again. The last person to display the correct day will get a strike and three strikes resulted in elimination. The last HouseGuest standing will win the Power of Veto. Paul was the winner, but on Day 92, decided not to use the Power of Veto. On Day 92, after James cast the sole vote to evict Corey, he became the eighth member of the jury.

Following Corey's eviction, the HouseGuests engaged in their final battle in the Hang In There Kitty Part 1 of the Final Head of Household competition. In this competition, HouseGuests had to follow a laser which would lead them to one of three endurance stations. Once the laser stops, they have fifteen seconds to climb onto the station. If the laser re-appears, they must jump off of their station and follow it again. If they fail to climb onto their station within 15 seconds or if they fall before the laser re-appears, they will be eliminated. The last HouseGuest standing will win Part 1 of the competition and automatically advance to Part 3. Paul was the winner. James and Nicole then faced off in the Snap Shot Part 2 of the Final Head of Household competition. In this competition, James and Nicole competed individually. They had to read a clue and place the three HouseGuests that applied to the clue into the roller coaster car. They had to push the car down the track, then take a snapshot of the HouseGuests while in frame. If they are incorrect or the HouseGuests are not in frame, they must try again. The HouseGuest who finishes all three snapshots faster will win Part 2 and advance to Part 3 against Paul. Nicole was the winner. Paul and Nicole had the final showdown in the Scales of Just-Us Part 3 of the Final Head of Household competition. In this competition, Nicole and Paul were read a series of statements made by the jurors. The HouseGuests were required to guess how the juror completed each statement. The HouseGuest with the most points after eight questions will be the final Head of Household of the season. Paul became the final Head of Household by a score of 4-3. On Day 99, after Paul cast the sole vote to evict James, he became the final member of the jury. On Day 99, after receiving Da'Vonne, Zakiyah, Paulie, Natalie and Corey's votes, Paul received $50,000 as the runner-up, Nicole received $500,000 and was declared the winner of Big Brother 18, the first female winner since Rachel Reilly in Big Brother 13 and the first female to win against a male in the final two and, Victor was revealed to be America's Favorite HouseGuest and received $25,000, bringing his cash winnings to $30,000.

Controversy and criticism

Bronte D'Acquisto and Paul Abrahamian were captured on live feed making racist remarks about fellow houseguest James Huling, who is ethnically Korean. Although Huling is a lifelong resident of the United States, D'Acquisto stated that she "will send [Huling] back to Hong Kong". In another incident, while discussing Huling, D'Acquisto said: "I want to kick his little Asian ass back to Hong Kong. Wherever he came from." Furthermore, Abrahamian referred to Huling as a "little Korean man" on multiple occasions in a derogatory manner. These incidents were not aired on the CBS television broadcasts, leading to speculation that CBS was editing the show to protect the image of HouseGuests who displayed bigoted behavior.

Jozea Flores also created controversy before the live feeds were streamed, saying that the 4th of July should not be a holiday. When a comment was brought up that "a lot of Americans died for our freedom," Flores replied with, "ain't nobody told them to do that." While his remarks were not aired, many of the HouseGuests talked about it. Corey Brooks also faced some criticism due to homophobic tweets that were found on his Twitter account, as well as homophobic remarks he made while inside the house. Brooks also faced more controversy after telling a story on the live feeds of his friend attempting to burn a goat. This was not shown on the CBS television broadcasts, leading to speculation that CBS was attempting to put out a clean image of Brooks.

Frank Eudy was criticized for sexual harassment due to his behavior with women in the house. In one instance, Eudy slapped Da'Vonne Rogers' buttocks without her consent and repeatedly called her a slut behind her back. Paulie Calafiore also made a series of offensive remarks to fellow GouseGuest Natalie Negrotti about her breast implants. Upon realizing that the house had grown weary of his abuse and running the game, including Natalie, Paulie began a campaign of harassment referring to Natalie's implants and body. Paulie routinely referring to Natalie as "F.T." (Fake Tits) and telling Negrotti that she was "as fake as those things on her chest." Paulie also received criticism for his misogynistic and sexist comments about women from New Jersey, stating they "play" men and "spit them out and eat them for breakfast, lunch and dinner." He referred to these type of women as "Jersey Girls" and afterwards received backlash from female viewers, particularly those from New Jersey, viewing it as a derogatory comment and reinforcing stereotypes.
