usually if you dont immediately know why youve lost or won, theres 2 reasons. if youve lost seemingly without reason or people leaving the game, its because the imposters have killed the amount they need to kill to win the game. If youve won without the imposters voted out or leaving the game, its because youve finished all your tasks and beat the imposters. idk if theres anything else that could happen to win or lose a game without knowing why immediately.
