Furiten — When You Cannot Ron
tips
Furiten restriction
If you previously discarded a tile that is now your winning tile, you are in furiten and cannot ron off another player (rules vary on tsumo). Hand A illustrates the bad discard history:
Furiten — cannot ron
234 Man
345 Pin
Wait (discarded)
678 Sou
456 Pin
Clean wait
Hand B keeps the same structure without the furiten discard issue:
Not furiten — safe ron
234 Man
345 Pin
678 Sou
456 Pin
