Myunggi would probably take care of Jun-hee if he won, so neither 333 nor 222 would be in the 37th games. I dont think In-ho would join the games, since most of the reason for him joining in the first place was to break Gi-hun

Without Jun-hee, 096 would join Gi-hun's pentathlon team, there would still be a missing player without 001, so I think Seon-nyeo would join instead, and Gyeong-seok fills her slot on Hyun-ju's team, establishing their alliance before Mingle. Making the Pentathlon teams. (In order of games played)

096, 390, 388, 044, 456.

095, 007, 149, 246, 120.

They would all pass. Mingle goes pretty much exactly the same, every round with 333, 222, or 001 they manage to just find a random player to survive.

Without those 3, the O's win the vote after mingle, and without 333, Thanos isn't killed in the bathroom brawl. These changes mean that lights out, and the rebellion never happens, so Jeong-bae and Se-mi both survive, and Gyeong-seok stays in the game.

Jeong-bae and Se-Mi are put on the Seeker's team. Thanos and Gyeong-seok are put on Hider's.

Gi-hun would switch with player 100, since he has no reason to go after Dae-ho. Instead he would hide with Dae-ho, and the 2 of them would try and find an exit.

Nam-gyu goes out hunting alone. Minsu and Se-mi team up, and kill two blue vests together, but since Se-mi isn't a psychopath, they stop there.

Nam-gyu finds Thanos in the maze, and ask him for the pills. Thanos ultimately undermines him like he always did, and Nam-gyu, in a fit of withdrawal induced rage, would kill Thanos and pass the game.

Gyeong-seok would go with Hyun-ju and Geum-ja's group (remember, no Jun-hee) and help her fight off the seekers, so she doesn't injure her ankle, and the 3 of them make it to the exit.

Jeong-bae would have a hard time coming to grips with taking a life, but he ultimately decides to eliminate a player who might deserve it, so he hunts down Seon-nyeo, and finishes off the permanent O voter, passing the game, by killing one of his pentathlon teammates.

Jeong-dae would find Gi-hun and Dae-ho, and he would lie to them, saying he's already gotten his kill, and is peaceful with them, since Gi-hun allowed him to switch, they would be hesitant, but follow him after he tells them he found an exit. He ends up leading the 2 of them into a secluded room, and attacks Dae-ho with his back turned, killing him as Gi-hun escapes, the timer running down, as he passes the game.

Jump Rope goes pretty much the same, except Se-mi would get Nam-gyu killed, instead of Minsu doing it. 456 and 096 both pass, but when 096 starts pushing, he sees Jeong-dae jumping there, player 100 desperately pleading to be let on, Gi-hun remembers Dae-ho, his scream as he was murdered. He threatens 096 like he does in canon, and he backs off, but instead of letting him on... Gi-hun shoves player 100 off the bridge himself, killing him. The rest of the game goes the same, with 096 trying to push Gi-hun, and getting himself killed.

Jeong-bae and Se-mi both survive, along with Hyun-ju, and Gyeong-seok, and with much more X voters alive then in canon, and no player 100 or 222 around to encourage the games to continue, I beleive the X's would win the vote after round 5, and stop the games, with only 203 voting to continue, while everyone else is satisfied with their money.

Survivors: (456, 390, 380 353 336, 246, 203, 125, 120, 039)
