American mahjong
Little reminders, close at hand
Four single-sided reference cards to keep beside your rack. Print at actual size and cut around each card. No folding or duplex printing.
The Charleston
First
Pass to: Right · Across · Left
Receive from: Left · Across · Right
Pause. Anyone may stop.
Second · if everyone agrees
Pass to: Left · Across · Right
Receive from: Right · Across · Left
Stop before anyone looks at second-left tiles. Once begun, finish all three passes. Blind only on first left and last right; own plus unseen tiles total three.
Courtesy: exchange 0–3 agreed tiles across. No jokers.
Jokers have a job
3 or more
Use jokers in matching groups: pungs, kongs, quints and sextets.
- Never a single or pair, even to win.
- Never in a Charleston or courtesy pass.
- A discarded joker cannot be called.
Exchange: after drawing or completing a legal exposure call, trade a matching natural for an exposed joker before discarding. A redeemed joker cannot join the group just called.
Before you call
Mahjong? A discard may complete a single, pair or concealed hand if the whole hand matches your card.
Otherwise: call only for a complete pung, kong, quint or sextet in an exposed hand that fits your card and earlier exposures.
No partial groups. No singles or pairs unless declaring mahjong.
Call the latest named natural discard before the next player racks, discards, starts a joker exchange or declares mahjong. Drawing alone does not close the window. A simultaneous call/rack favors the call.
Who pays what?
On a discard: discarder pays 2× the hand value; each other player pays 1×.
Self-picked: each other player pays 2×.
Eligible jokerless hand? Double the card value first.
No extra bonus for Singles & Pairs. Quints hands on the supported NMJL card cannot qualify.
A win completed by joker exchange is self-picked. Dead hands still pay.
Four-player references. Use your own NMJL card for complete hands. Each card is 88 × 86 mm.
