Get multiple (recommend 3) players, or private windows/devices, in a game. Using one of the accounts, answer question wrong. Once in the killing Floor, use one of the following methods to survive the killing Floor:
1) Take a picture of the screen, pause/unpause and solve the puzzle.
2) Pause/unpause and answer questions quickly for points {mainly the math Floor}
3) Use the other accounts to sabotage and guess correctly {for example poison the cup and now you know which one not to drink}
This has to be done all in a single game/play through.
