Mahjong for two players

There is no single official two-player rule book for the Chinese or Hong Kong game, so what follows are the approaches players use most, simplest first. Pick one, agree on it before you start, and keep the rest of the rules from the four-player game.

What changes with two players

Three things stop working when two seats are empty. The wall lasts too long, because there are twice as many tiles per player as usual. Chows become too easy, because the other player is always the one who discarded just before you. And seat-based scoring has two winds nobody sits in. Each approach below fixes these in a different way.

1. Full set, standard rules

The quickest way to start: build the wall exactly as for four players, deal thirteen tiles each, and play. Sit opposite each other as East and West.

• Allow chows from every discard, since your opponent always plays just before you.

• With twice the usual tiles per player, a hand can drag on. Agree to call it a draw once a set number of tiles is left in the wall, for example the last 40.

• Expect long hands with lots of discards in the middle of the table.

Good for a first evening when you just want to get the tiles moving.

2. A smaller set (our pick)

Many two-player games in China and in mahjong apps use a reduced set. The usual version keeps one suit and the honors:

1. Set aside the dots and bamboo. Keep the flowers and seasons in if you like bonus tiles, for 72 in total.
2. Each player builds a wall 16 tiles long and two high, or 18 long with the bonus tiles. Push the two walls together end to end.
3. Deal thirteen tiles each as usual. The dealer takes a fourteenth and discards first.
4. Play with the normal rules: pung and kong from any discard, chow from your opponent's discard.

With only one suit, hands come together quickly and the game feels close to the four-player pace. It also changes the strategy: everyone is collecting the same suit, so watching your opponent's discards matters much more.

3. Two hands each

In American homes, two players often fill all four seats by playing two hands each, one on each side of them. The rules stay the same, although many players skip the Charleston when playing this way. You play both of your hands in turn order, each hand can win on its own, and the game ends when the agreed number of hands has been won.

It is the most faithful option and good practice for a real table, but it takes concentration to keep two hands straight, and it is slower.

Scoring for two

Keep it simple. Use the usual hand values, and have the loser pay the winner. Drop any scoring for seat winds or seat flowers that refer to the two empty seats, or treat East and West as the only seats. If you use a minimum to win, lower it by one, because reduced sets make big hands harder to build.

Tips for two-player games

• Read the other hand. With one opponent, every discard tells you something. If they have not thrown a single wind all game, they are probably keeping winds.

• Hold back the tile they need. Defense matters more than in a four-player game, because there is only one person to feed.

• Play more hands. Short hands mean luck evens out quickly. Agree on a number of hands, or a score to reach, before you start.
