The long history of Tetris resulted in Guinness World Record awarding the franchise 9 world records in the Guinness World Records: Gamer's Edition. These records include, "Most Ported Video Game", "Game With the Most Official and Unofficial Variants", and "Longest Prison Sentence for Playing a Video Game", which is held by Faiz Chopdat, who was jailed for four months for playing Tetris on his cell phone while on a flight to Manchester, England. He refused to stop playing after being repeatedly warned by the cabin staff.
