As a child, Guoga was the Rubik's Cube champion of Lithuania before moving to Melbourne, Australia at the age of 11. He has played poker since the age of 18, and is known for his outlandish table talk and frequent intimidation of his opponents. He had a fifth-place finish in the World Poker Tour Grand Prix de Paris 2003. He finished in the money twice at the 2004 World Series of Poker in Seven-card stud and Pot Limit Texas hold 'em tournaments and three months later earned his then biggest tournament money finish in the WPT Grand Prix de Paris 2004, where his second-place finish to England's Surinder Sunar earned him $414,478. He finished on the bubble later in the same month at the WPT 2004 Mirage Poker Showdown. On August 7, 2005, he won the £5,000 No Limit Hold-Em Main Event of the European Poker Championships, earning £260,000 ($456,822).

Also in 2006, he finished second to Yosh Nakano while representing Australia in the inaugural Intercontinental Poker Championship, taking down $150,000. True to his reputation, Tony G launched many verbal assaults against his opponents, most notably when he eliminated Russian Ralph Perry in fourth place. Tony G started to provoke Perry when he was deciding how to play his hand before the flop. When Perry called Tony G's all-in with a worse hand, Tony G proceeded to ridicule and lecture him. Tony's comments were so scathing that it prompted commentator Gabe Kaplan to quip "I think Tony G is speaking more like a Lithuanian than an Australian" and "Tony G could singlehandedly reignite the Cold War". Guoga was more respectful of some other players, such as Doyle Brunson, calling Doyle his idol after eliminating him.
In November 2006, he won the Asian Poker Tour event held in Singapore, walking away with $451,700, half of which he indicated he will give to Asian and Australian charities to be nominated by Betfair. In February 2007, he appeared on the NBC television program Poker After Dark, coming in third place behind winner Phil Ivey. In November of the same year, he won a tournament in Moscow, earning $205,000. Often telling his opponents that he has a "big heart", Tony claims that he left all of his prize money with the officials to give to Russian orphanages, having been inspired to do so by Barry Greenstein's habit of donating all his poker tournament winnings to charity. In January 2008, Tony received the Shining World Leadership Award in Melbourne Australia. As of 2011, his total live tournament winnings exceed $4,000,000. His 14 cashes at the WSOP account for $429,897 of those winnings.
