Who’s playing

Mon and multipliers

The base is simply the yaku value in mon times the per-mon stake. Doubling at seven mon or more is the most common house rule and is on by default; you can turn it off.

Tables disagree on koi-koi. You can choose doubling per call, doubling once if any call was made, or no multiplier at all — settle it before you start and nobody argues later.

Common questions
