Shuugi

Shugi 「祝儀」 is a set payment (in money, not points) others owe when someone wins with a special hand. When used, shuugi is awarded for: akadora, certain luck-based yaku (uradora, ippatsu, rinshan), and/or yakuman. It is used almost exclusively in gambling settings.

Shugi is generally marked with poker chips. Each player starts with a set amount of chips, usually 5. When a ron happens, the ronned player pays 1 chip. When a tsumo happens, each player pays the winner 1 chip. Chips are then exchanged for money at the end of the game.
