How to check a Mahjong hand

Not sure where to start? Load the example, then calculate it. Change a tile or winning condition and calculate again to compare the result.

  1. Choose the rules used by your table.
  2. Enter concealed tiles and called sets; put the winning tile last.
  3. Set self-draw or discard win and any special conditions.
  4. Read the detected patterns and payments, then check their requirements in the table.

These calculators follow mahjchina’s rules. They evaluate one winner, not a whole match ledger. Previous kong payments, simultaneous winners, draw penalties and competitive points are outside the result. Local rules may differ.
