You're missing some of the best ones, like that time Yugi basic blinded a guy for life into seeing nothing but mosaic patterns, the one where Yugi just straight up lights a dude on fire (who, to be fair, WAS a goddamned escaped serial killer), or the time Kaiba, after losing his first game of Duel Monsters against Yugi and spending some time trapped in a card, built a freakin' tower of deadly games to put Yugi and the gang through, including (IIRC) a game of Lazer Tag against a bunch of ex-military guys where the vests explode and another where they just start dropping blocks on them with them having to avoid them all and get to the door before it gets blocked off (with Tristan seemingly dying to ensure everyone else makes it).
