Quick Note

• Tile: Similar to cards in Poker. There are a total of 136 tiles.

• Wall tile: Tiles that have not been drawn.

• Hand tile: Tiles held by players.

• Discard tile: Tiles discarded by players.

• Yaku(役 or 役): Winning pattern. A player wins when their hand tiles form a winning pattern.

• Chii (吃 or チー): Players can make an open-sequential-tiles, a sequence (3 consecutive tiles in the same suit), by calling “chii” using a tile discarded by the left player, who is the prior player. This means every player can claim the left player’s discarded tile to make a sequence.

• Riichi (立直 or リーチ): A player can declare Riichi if and only if the player needs exactly one more tile to have a winning pattern and has not Chii-ed in the game. After declaring Riichi, the player can only discard the tile they draw on that round.
