Singapore Fist

Game rules

Preparation: Two people face each other. First agree on the amount of each penalty.

1. Clap twice and play rock-paper-scissors; the winner becomes the attacker.
2. Clap twice again. The attacker points up, down, left, or right, while the defender turns their head in any direction at the same time.
3. If the directions match, the defender loses and takes one unit of punishment. If they differ, no one loses and you play rock-paper-scissors again.

Example: The attacker points right and the defender also turns right, so the defender drinks one unit. If the defender turns up, neither player drinks and the game starts again.
