How to Play American Mahjong with 3 Players

Four players is standard, but three shows up all the time — someone cancels, someone's late — and American Mahjong plays perfectly well with three. There are two established ways to do it: the official NMJL® method, and a popular house-rule version that keeps the Charleston by inventing a fourth player.

The official way: no Charleston

The National Mah Jongg League's official three-player rules are simple:

• Build all four walls as usual, then deal 13 tiles to each of the three players, skipping the empty seat (East takes 14, as always)
• Skip the Charleston entirely — no first, no second, no courtesy pass
• East discards and play begins; otherwise every rule is the same as four-player
• The unused fourth player's share stays in the wall and gets drawn from during play

Why no Charleston? The passing pattern is built for four. With three, one player would receive from both neighbors before passing, and tiles headed for the empty seat would be a free dump rather than a real trade. And because there are more wall tiles per player, everyone gets extra draws anyway — the game runs a little longer and walls out less often.

The house-rule way: the ghost player

Many groups love the Charleston too much to give it up, so they add a fictional fourth player — often nicknamed "Bob." But you can't deal a normal hand to an imaginary player and expect it to pass tiles it can't choose. Instead, Bob gets a pre-set pool built from his wall, so every pass to and from him is deterministic:

• Deal as usual — 13 tiles to each of the three human players (14 to East). Bob gets no rack and no hand.
• Before the Charleston begins, slide 21 tiles off Bob's wall and set them in front of him as 7 face-down stacks of 3 — one stack for each pass a player might make with him (the three first-Charleston passes, the three second-Charleston passes, and the courtesy pass)
• When you're due to receive from Bob, take his next pre-set stack of 3
• When you're due to pass to Bob, slide your 3 tiles back onto his wall to rebuild it — never into a hand
• If the Charleston stops early, put any unused stacks back onto Bob's wall

Once the Charleston ends, Bob is ignored for the rest of the game. His rebuilt wall stays in play and is drawn from in the normal rotation when the players' own walls run low. The usual Charleston rules still apply — including never passing a Joker.

It's not official, but it's widespread. Just agree before you deal which version your table is playing.

Everything else stays the same

Both versions use the same 152-tile set, the same year's card, the same calling rules, and the same scoring — with the discarder still paying double. If you can play four-player American Mahjong, you already know how to play with three.
