2by2 is a lottery game played in Kansas, Nebraska, and North Dakota. It is drawn nightly at the Iowa headquarters of the Multi-State Lottery Association (MUSL). Kansas and Nebraska started the game in 2002; North Dakota joined in 2006.
Players choose two numbers from 1 through 26 in each of two number fields (red and white.) Only one match (in either field) is needed to win. The top prize of $22,000, originally $20,000 (which is fixed, rather than a jackpot), is won by matching all four numbers.
Players who buy a ticket good for seven consecutive drawings are eligible for a doubling of the top prize (to $44,000) if the top prize is won on a Tuesday.
MUSL, from 1996 to 1998, offered a similar game called Daily Millions, with a grand prize of $1 million cash. Daily Millions had red, white, and blue number fields, in which players chose two numbers of each color.
The Arizona-only game 2by2, begun in 2009, was played in the same manner; it had a top prize of $20,000. The Arizona version of 2by2 held its final drawing May 17, 2014; it was replaced by All or Nothing, of which it joined several versions of that game, including one played in both Minnesota and Iowa.
