DOTS (Numbered 1-9; 4 of each, for a total of 36)
BAMS ("Sticks" numbered 1-9; the 1 looks like a bird; there are 4 of each, for a total of 36)
CRAKS (Chinese characters numbered 1-9; there are 4 of each, for a total of 36)
WINDS (Chinese characters labeled E, S, W, N; there are 4 of each, for a total of 16)
DRAGONS (Red Dragon, Green Dragon, White Dragon; there are 4 of each, for a total of 12; the whites may have a rectangular design or may be blank)
