Playing rules
- Four players use 108 suited tiles. Choose a missing suit and discard it first whenever present. Pung, kong and win require clearing your missing suit first; chow is not allowed. No opening tile exchange.
- Base score 1. Plain hand ×1, all triplets ×2, seven pairs ×4, pure suit adds ×4, each four-of-a-kind adds ×2. A kong draw, kong discard or robbed kong adds ×2; hand value caps at 16. Self-draw adds 1 point from each active opponent; a discarder alone pays discard wins. Match points do not change platform chips.
- A discard may have multiple winners. Winners leave subsequent play and payments. End after three winners or an empty wall. Exposed kong costs the discarder 2; concealed kong costs each active opponent 2; added kong costs each 1. At exhaustion, missing-suit holders pay every other player, including winners, 16. Other non-listening players pay each listening player their maximum hand value. Active non-listening players refund kong income.
- Timed-out and departed players act automatically. Passing a win blocks discard wins until your next draw.
