Japanese mahjong scoring rules: Difference between revisions

'''Fu''' {{kana|符}} (''pronounced as foo'') takes the hand composition into consideration in terms of [[mentsu|tile melds]], [[machi|wait patterns]] and/or win method.  Every hand begins with a default start value of 20 fu.  To determine the final number of fu, the sources of fu are added up along with the base number and then rounded up to the next multiple of 10. The exception is the [[chiitoitsu]] yaku, which is fixed to 25 fu and is not rounded.  While fu may be counted for hands worth 5 han or greater, it is not necessary.  At 5 han and above, the hand value is dependent only on the han count, and the fu count is ignored. When playing with the uncommon [[aotenjou]] rule, however, the fu count is used for hands of any han value.
