Scoring
Fan
Also called: 番, MCR scoring unit
MCR (and Sichuan) scoring unit. Each fan pattern has a fixed point value 1-88.
Fan (番) is the scoring unit in MCR (Chinese Official) mahjong and in Sichuan. In MCR, fan is additive — you sum all applicable patterns up to a hand total. In Sichuan, fan is exponential — total payout = 2^(total fan). MCR requires an 8-fan minimum to declare a winning hand; Sichuan requires 1 fan. Han in Riichi and fan in MCR/Sichuan are conceptually similar but the math is totally different.
