Rush is the game played within a certain period of time after the game starts.

Rush Rules

• As soon as the game starts, the counter starts counting down.
• Two players have a shorter playing time.
• The game ends as soon as the time runs out.
• The last card drawn is discarded at the end of the time limit.
• If both players fail to knock or gin, at the end of the time, the deadwoods are subtracted from each other and added to the one with less deadwood.
