As with any game, certain infractions in Mahjong are considered fouls, and are enforced through a penalty system.
The player commiting a foul pays a fine in chips, which is split among the 3 remaining players.
When a Non-dealer commits a foul, he pays 4,000 to the Dealer and 2,000 each to the remaining players.
When the Dealer commits a foul, he pays 4,000 to each player.
