of two han or more from yaku when the honba count surpasses a certain number. Usually, this count is five or more. Chombo Under the rule of chombo (チョンボ, 錯和 or 冲和), a player is given an infraction. Point penalties vary by organizations and/or events. Typically, a player pays a penalty of the same amount as mangan to other players in most rules. A non-dealer pays 4,000 to East and 2,000 to the other two players, while a dealer pays 4,000 to each. In other times, chombo does not affect the current score of the game; and instead, the penalty is applied at the end of the game. Chombo occurs for any of the following: Invalidly claiming a winning hand Winning on a discard under the situation of sacred discard (furiten) Revealing a false rīchi, that is, rīchi with a hand that is not in the state of tenpai Closed kan after rīchi if the kan changes the hand structure (in other words a kan of a tile after rīchi is not allowed if the hand can be interpreted such that the tile is a part of a sequence) Having more tiles than allowed (depending on the rules) Knocking the wall over so that it cannot be recovered to the way it was before In game infractions, such as the false rīchi and invalid kan after rīchi, they are caught only after draws or winning declarations by players who declared the rīchi. If other players happen to win the hand, then the infractions are not revealed and therefore made null and void. Any rīchi bets are returned to the players after the end of a chombo hand. Other settings for chombo apply point penalties after the game's conclusion. This is especially the case under tournament settings. Under this method, players do not benefit with any point gains. Instead, the infracted player solely takes a point deduction. The deduction may be set to any specified number. Final points and place At the end of the game, the final scores may be calculated. Under casual game settings, this calculation is not necessary. However, under more formal settings, it may be required. This calculation takes the game's scores and adjusts them according the setting of oka and uma, which were predetermined before the game. The calculation for each player is as follows: End score = ((End points + Oka - Target)/1000) + Uma
