The short answer: Three dice for most mahjong games. Chinese-style games use three; riichi and some other variants use two. The dice do exactly one job — they pick the dealer and decide where the wall breaks. Nothing else rolls during play.
Mahjong gets all its drama from tiles, but the dice have a small, quiet job at the start of every hand. Lots of players go years without thinking about them. Here’s everything you actually need to know.
How many dice do you need?
- Chinese mahjong: three dice, the standard.
- Japanese riichi: two dice.
- American and other variants: usually two, sometimes three — house rules decide.
What do the dice actually do?
- Pick the dealer: everyone rolls, and the highest total becomes East.
- Break the wall: East rolls again and counts the total.
- Find the spot: count that many stacks from the corner of the wall, and dealing starts there.
- Move on: the dice come back out only between hands, to pick the next dealer.

Do I need dice for mahjong solitaire?
No. Matching games deal tiles straight onto the board. Dice belong to the four-player game.
How is the wall break counted?
Players count the dice total in stacks around the wall and deal from the break point. The exact direction varies slightly by ruleset.
Can you play with one die?
You could, but two or three is standard so the break point isn’t trivially predictable.
Are dice rolled again mid-game?
Not during play. They come out between hands to decide the next dealer, then sit quiet again.
