Game rules

Preparation: 2 or more people, four dice and one die bowl. It is first agreed that the person with the lowest point in each round will receive one unit of punishment.

Players roll four dice in sequence. You must throw at least one pair to get a point; if all four are different, or if three are the same and one is different, you must re-throw.
A pair: Set aside the matching pair and add the values of the other two dice. For example, 2, 2, 3, and 5 are 8 points.
Two pairs: Take the pair with the larger number and add them together. For example, 1, 1, 4, and 4 score 8 points; 2, 2, 6, and 6 are 12 points, also called "eighteen".
Four of a kind: Four dice are identical and beat all normal points. If several players roll four of a kind, compare the face value; 6 is highest.
Compare after everyone has valid results. Four of a kind ranks highest; ordinary scores range from 3 to 12, with higher scores ranking higher. The player with the lowest score receives one unit.
When there are multiple players with the same lowest point, only those tied players reroll until the player with the lowest score is determined.

Example: Two 3s are deducted from 3, 3, 5 and 6 to get 11 points; 1, 2, 4 and 6 have no pairs and must be re-rolled.
