Payout reference
Base value = points on your card (you type it in). Jokerless doubles that value for payout — unless Singles & Pairs is on (no jokerless double). Won on discard — discarder pays 2×; other two pay 1× each. Self-picked — all three opponents pay 2× each. Wall game — no winner, 0 payouts.
Highest session total wins. Live payout preview appears before you save.
Not affiliated with the National Mah Jongg League. Does not reproduce any NMJL card hand charts or artwork. Bring your own current card.
