American mahjong (NMJL rules) is a four-player game where legal hands are defined entirely by an officially published card that changes every year, played with 152 tiles including 8 wildcard jokers and preceded by the Charleston tile-passing ritual.
| Total | 152 |
| Suits | Craks, Bams, Dots — 1–9, four of each |
| Honours | Winds (E/S/W/N) and Dragons (Red/Green/White) — cannot substitute for suited tiles |
| Flowers | 8 flowers — a distinct honor category; how many a hand needs is set by that year's card |
| Jokers | 8 jokers — wild only in groups of three or more (pungs/kongs/quints), never singly or in a pair |
152 total = 108 suited + 16 winds + 12 dragons + 8 flowers + 8 jokers.
A winning hand: A hand must exactly match one of the patterns printed on that year's official NMJL card — not a generic four-sets-plus-pair shape.
Scoring: Each pattern on the annually-published card carries a preset point value (commonly 25–75); self-draw and jokerless wins double the score.
| Unit | points (card-assigned) |
| System | fixed point value per card pattern |
| Minimum to win | 25 points is the lowest-value hand on the card |
| Limit | no universal cap; the highest patterns (Singles & Pairs) reach ~75 points |
Who pays: Commonly: on a discard win the discarder pays double the hand's points and the other two pay the base amount; on a self-draw all three pay double.
In Mahjiku. American mahjong is defined by the annual NMJL card and jokers — a different game from faan scoring, not supported in Mahjiku.
