So the reason that Tetris Attack isn’t a category on Twitch, is because (with a few special exceptions) Twitch will only pull the original version of a game from IGDB, and Tetris Attack is a version of the original game ‘Panel de pon’ that was just renamed for the international market.
Twitch currently has the wrong Panel de pon game on Twitch, ’ Panel de Pon Event ‘98’ but this will be changed so that the correct original ‘Panel de pon’ will be a category on Twitch.
