FAQ

Common questions

Do MCR and HK count the same patterns?+

Many patterns overlap by name (All Pungs, Great Three Dragons, Thirteen Orphans) but with totally different point values. A 6-faan HK All Pungs becomes 6-fan in MCR — same name, but in MCR it's a baseline pattern, while in HK it nearly doubles your score.

Why does Hong Kong feel more luck-based?+

Exponential 2^faan payouts mean a 5-faan hand pays 32 base units while an 8-faan hand pays 256. One lucky draw can swing the entire game. MCR's linear fan addition makes scores more predictable.

Is Hong Kong easier to win in?+

Generally yes — the 3-faan minimum is much easier to clear than MCR's 8-fan minimum. Casual HK games may even allow 0-faan 'chicken hand' wins for a fixed payout.
