A player penalized with chombo must pay a specified point penalty. The most common is a [[mangan|mangan-sized]] penalty, i.e. a "reverse mangan [[tsumo]]". A non-dealer must pay non-dealers 2000 points and the dealer 4000 points. A dealer with chombo must pay 4000 points to each player. Some tournaments/professional leagues may have a higher penalty.

When chombo is applied will depend on the rules. The simplest case is to adjust points directly after the game ends. To save time, the chombo adjustment may be done after the entire game ends (along with [[oka and uma]]).

The 8000 point penalty is not flat, and may be adjusted as needed. For instance, intentionally committing chombo to disrupt another player's [[yakuman]] could be viable for the "cost" of 8000 points. In this case, a tournament judge could eject the player or increase the penalty value.

During riichi, a player may call [[kan]] with an ankan, or closed kan. However, this is invalid when the player's [[Machi|wait]] changes.  Typically, this occurs when the four concealed tiles are connected to another [[mentsu|tile grouping]]. Other players cannot detect this rules violation immediately, and it is punished at the same time as a noten riichi.
