'''Fu''' {{kana|符}} (''pronounced as foo'') is a component of [[scoring]]. It takes the hand composition into consideration in terms of [[mentsu|tile groups]], [[machi|wait patterns]] and/or win method. In addition, 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 nearest 10.
