Unsure, and depends on what counts as "playing". My brother got an old computer for cheap a long time ago. There was a floppy disc with a game on it. I don’t have more impressions of it than walking around in some weird geometry on the black-and-white monitor. Some sort of chess-board floor I think.
Truly gaming would probably be one of those small Tetris handhelds. I still have mine. Used to play for hours on car rides. Either that or Game Boy Pocket.
