Why Riichi
Mahjong?

A four-player game of incomplete information where probability, psychology, and pattern recognition collide. Every draw changes the calculation. Every discard is a tell.

Chess gives you perfect information. Poker gives you hidden cards but only one opponent. Riichi mahjong gives you three opponents, a wall of 136 tiles, and the knowledge that every tile anyone discards tells you exactly what not to be afraid of — and hints at what you should be.

It rewards both the mathematician and the detective. You build hands toward scoring combinations called yaku, manage your risk of dealing into an opponent's win, and read the discards to model what the table is holding. No two hands play the same way.

What keeps it interesting
Probability

Tile counts are public. You can calculate draw odds in real time — then feel them disagree with the wall.

Discard reading

Every discard is a clue. Build a mental model of each hand and avoid the tiles that will pay them out.

The declaration

Lock your hand. Stake 1,000 points. Signal to the table: I'm ready. A gamble, a statement, a pressure play.

Variance

Even strong players lose sessions. The measure is decision quality across thousands of hands — not any single result.
