American Mahjong is built for four. Life is not. Here is how to keep playing when you are three, and how to handle the happier problem of five people and four seats.
Three players: what actually changes
The game works with three, and the tile count does not change: you still use the full set, and each player still holds thirteen tiles. What changes is that the wall lasts noticeably longer per player, so hands run further and more of them get completed.
Each player builds a longer wall section, or you build the same square with the fourth side split between everyone. Either works as long as the total is right and everyone can reach.
The Charleston with three
This is the real adjustment. The standard Charleston passes right, across, and left, but with three players there is no across. Most three-handed groups pass right, then left, then right again, keeping three rounds so tiles still circulate properly.
The courtesy pass at the end is usually dropped, since it is defined as a swap with the player across from you. Some groups substitute an agreed swap with either neighbour. Decide before the deal.
What three-handed play feels like
Faster and looser. With one fewer player discarding, you see fewer tiles per round, so information about what others hold accumulates more slowly. Defense gets harder because there are fewer discards to read.
Hands also tend to complete more often, since the extra wall depth gives everyone more draws. Expect fewer wall games and more finished hands than a four-handed session.
Two players
Two-handed American Mahjong is possible but it is a different game: no meaningful Charleston, very little to read, and most of the strategic texture gone. It works as a way to practice recognizing hands, not as a substitute for a real session.
If you are two and want to improve, drilling hands against a simulator is honestly better practice than playing each other, because you see far more deals per hour.
Five people, four seats
The standard solution is a rotating sit-out: the fifth player sits out a hand and swaps in, usually replacing the player who was East. Some groups have the sitting player keep score or handle the shuffle so they stay involved.
The sit-out is also the best teaching seat in the house. A beginner watching one hand over an experienced player's shoulder learns more than they would playing it badly, which is why five is often better for a mixed group than four.
