Game rules

Preparation:2 or more people, a transparent cup, a bottle of drink and a stable tabletop. First place the cup in the center of the table and fill it until it is about 80% full.

Use rock-paper-scissors to choose the first player, and players take turns pouring drinks into the same cup clockwise.
At least one drop must go into the cup each round; more or less is decided by the player. The round is completed when the mouth of the bottle is away from the mouth of the cup and the table is still dry.
As long as there is liquid flowing out of the cup or the liquid level in the cup overflows during the pouring process, the current player will lose immediately.
The loser accepts the punishment agreed at the beginning; empties the central cup until it is about 80% full and starts the next round.
If the entire circle does not overflow, the game will continue and does not end merely because everyone has poured once.
