Japanese Mahjong scoring rules are used for Japanese Mahjong, a game for four players common in Japan. The rules were organized in the ''Taishō'' to ''Showa'' period as the game became popular. The scoring system uses structural criteria as well as bonuses. Players start with 20,000 to 30,000 points. Scores are counted using sticks of 10,000 points, 5,000 points, 1,000 points and 100 points. A game often ends when all the points of a player are lost, which is a situation called ''hakoten'',〔Literally "(empty) box points." Japanese mahjong sets often have four boxes to store tiles, and they are often used for point sticks. (Japanese: ハコテン)〕 ''dobon'',〔Sound of something heavy like a stone falling into water. (Japanese: ドボン)〕 ''buttobi'',〔(Japanese: ぶっとび)〕 etc. There are two criteria in determining the winning points: ''han'' and ''fu'', which correspond to a points table. ''Han'' is the unit for the value of ''yaku'', which are particular patterns or conditions of a hand. ''Fu'' is the value of melds, waits and "going out". ==Steps of calculation== The payment to the winner of a hand is calculated as follows: :1. Counting ''han'' (飜) :2. If it is five ''han'' or more, it is ''mangan'' (満貫) or more and the calculation of basic points is omitted :3. Counting ''fu'' (符) :4. If it is clear that the ''han'' and ''fu'' yield more than ''mangan'', the calculation of basic points is omitted :5. Calculating the basic points based on the ''fu'' and ''han'' :6. Multiplying the basic points depending on whether the winner is the dealer or non-dealer, and whether the hand is won by ''tsumo'' or ''ron'' :7. Adding bonuses based on the number of counters'' :(8. Adjusting the payment by the ''wareme'' rule) In the case of a draw, points are transferred according to the ''nō-ten bappu'' rule. In the event of a penalty, such as claiming a win with an illegal hand, then points are transferred via the ''chombo'' rule. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Japanese Mahjong scoring rules」の詳細全文を読む スポンサード リンク
