The short answer: Yes, absolutely. Three-player mahjong is common, and Japan even formalized it as sanma, three-player riichi with a reduced tile set, adjusted scoring, and one wall left unbuilt. Casual clubs usually just skip the fourth side and add house rules. It plays fine at most tables.
Third player just bailed and you’re down to three. Don’t fold up the table. Mahjong with three players is a real format with real history, not a broken game. Here’s how it works.
How do you set up a three-player game?
- Leave one wall untouched: three players draw from the active walls while the fourth side stays built.
- Drop some tiles: many house games remove a few suits or extra winds so hands finish at a normal pace.
- Keep the basics: dealer, turn order, and the goal — form a winning hand — don’t change at all.
What is sanma, and how does it compare?
In Japan, three-player riichi (sanma) has formalized rules: the tile set shrinks, one wall is never built, and scoring adjusts so hands stay fair without a fourth hand in play. Exactly which tiles disappear, and how the north wind is treated, varies by rulebook. Casual three-player games are looser — same walls, fewer players, whatever your group agrees on. Both work; sanma just has a rulebook behind it.

Can two people play mahjong too?
Yes. Duos shorten the walls and speed everything up. See our how to play mahjong with 2 players guide for the setup.
Is a three-player game faster?
Usually. Fewer tiles and fewer opponents mean hands come together quicker, and rounds rarely drag as long as a four-player game.
Does American mahjong work with three players?
American mahjong is designed for four racks and a full wall, but experienced groups adapt it casually. A fourth player is still the smoothest option.
