The Four Core Payout Multipliers Explained
1. The Discard Liability Rule (2x Discarder, 1x Others)
When a player claims a fresh discard to declare Mahjong, the discarder is held responsible and pays double ($2\times$ base points). The other two non-winning players at the table pay single ($1\times$ base points).
2. The Self-Drawn Wall Double (2x from All Players)
When a player draws their own 14th tile directly from the working wall, every non-winning player at the table pays double ($2\times$ base points).
3. The Jokerless Hand Bonus (2x Total Value)
Any hand on the NMJL card that permits Jokers but is achieved with 100% natural tiles is awarded the Jokerless Double. Note: Hands in the Singles & Pairs category already forbid Jokers and therefore do not receive an extra doubling bonus.
4. Third Exposure Table Liability (Full Table Penalty)
If an opponent has 3 exposed melds on their rack that unambiguously define only one possible winning hand on the official NMJL card, any player who discards that specific winning tile is penalized with Table Liability and must pay for all three non-winning players at the table.
3-Player Settlement Note: Payout ratios remain identical, but total table payouts adjust to 3x (discard) and 4x (self-draw) since there are only 2 paying opponents. Read our guide to
