In September 2002, Chopdat, Faiz, 23, of Blackburn, was sentenced to 4 months in prison after refusing to turn off his mobile 3 times on a flight from Egypt to Manchester. The crew asked him three times to switch off the phone, which was interfering with the plane's communications system, but each time Chopdat turned it on again. He was playing Tetris and got arrested, because playing Tetris is prohibited by law in airplanes (if you play Tetris, the FBI confiscates your phone and you are sentenced to 11.5 years in prison: 10 for possessing an unlawful item, and 1.5 for circumventing airport security (which has banned everything from metal in general to fidget spinners)).
- There are many other laws against Tetris. See 13b, 18b, and 21b to learn more. So this is just one way to go to prison for playing Tetris.
- Anyone who has gone to prison for playing Tetris gets Template:Arrested on his page.
