حكم اجباري is a unique game designed for three players, where each player is dealt a hand of 10 cards, totaling 30 cards in the game. Before distribution, one player selects a specific rule from a set of options like Hase, Shirea, Spade, or Diamond. Players then write down the number of food items they have on a red counter, with a minimum of 2 items. Points are awarded based on successfully claiming the recorded food items, with deductions for unclaimed items. Additional features include the addition of "San" to the game and the inclusion of projects, where the player with the largest project gains points in the green counter based on the project's size.

The game introduces strategic elements where players must manage their food items efficiently to score points. With rules like "San" and project scoring, players need to balance their actions to maximize their points. The game's unique mechanics provide an engaging experience for three players, making each round a test of skills and decision-making.
