MCR vs Taiwanese
MCR is the international tournament code; Taiwanese is the family-table tradition of Taiwan. Both are Chinese-origin, both use chow/pung/kong melds — but the structures and scoring philosophies couldn't be more different.
81 fan patterns with strict exclusion rules and 8-fan minimum.
5 melds plus a pair instead of 4 — bigger hands, faster draws.

Common questions
Are these two even comparable?+
Loosely. Both have Chinese roots, both use the same tile set, both score on a flat point system. But the 14-vs-17 tile difference and the 81-vs-13 pattern difference mean they play like different games.
Why doesn't MCR use 17 tiles like Taiwanese?+
MCR was codified by international authorities standardizing on the most common Chinese mainland format (14 tiles). Taiwan's 17-tile tradition was deliberately not adopted to keep MCR closer to global norms.
