Errores

During 'Red Light - Green Light' the player with the number 293 gets shot, reappears a few minutes later and gets shot again.

Crew or Equipment available: At about the 18:20 point as 390 and 456 are making their way to the Green Light/Red Light game, while it appears that a crew member's hand can be seen at the bottom of the screen in what looks like an attempt to pat or pull down the back of 390's jacket, the actor is actually scratching his back.

At the end of the first game, the 11 and another soldier communicate with each other, presumably without the use of voice distortion, thus violating the otherwise closely guarded secret of their identities.

Seong Gi-hun (player 456) should have immediately suspected Oh Young-il (player 001 - Hwang In-ho) the minute he saw him, since in the previous season, it was the very player 001, Oh II-Nam, that was the mastermind behind the games. Furthermore, their names are similar/have the same surname - Oh.

Because of these 2 very strong signs, anyone would have suspected player 001 immediately. So it would make sense that Gi-Hun shouldn't have been so trusting of him at all, instead of forming an alliance with him throughout the games.
