Mahjong Tile Guide
A standard National Mah Jongg League-style set commonly contains 152 tiles:
36 Craks
36 Bams
36 Dots
16 Winds
12 Dragons
8 Flowers
8 Jokers
Each numbered suit contains four copies of tiles numbered one through nine. There are four copies of each wind and dragon. Flowers and jokers have special rules and do not function like ordinary numbered tiles.
Some sets include additional tiles for other Mahjong styles. Before beginning, confirm that your set contains the correct tiles for the version you plan to play.
