Ms. Cox bought her son a version of a Nintendo console called the RetroN, which used the same hardware as the original Nintendo console, from a pawn shop, as well as an old cathode ray tube television to help him get started. In a week, Willis said, she plays about 20 hours of Tetris.“I'm actually fine with it,” said Ms. Cox, a high school math teacher. “He does other things besides play Tetris, so it wasn't that hard to say OK. It was harder to find an old CRT TV than it was to say, “Yeah, we can do this for a while.”For decades, players have "beated" Tetris by hacking the game's software.
