Enter each numbered tile once: 1125 means two 1s, a 2 and a 5. Leave unused fields blank. Colours can use any suit, but different colours must use different suits.
Pattern notation: 1–9 = numbered tiles; F = flower; N/E/W/S = winds; 0 = white dragon; D = dragon matching the group's suit (Bams: green, Dots: white, Cracks: red). Jokers fill groups of 3 or more identical tiles. Each space-separated group is treated as a separate group.
