Mahjong Poker

Playing Poker Games with a Mahjong Set

In theory, you can substitute a poker deck for a mahjong set and still use standard poker hands:

  • Remove the flowers and seasons
  • Play with all 4 sets of tiles
  • Pip cards (coins, strings and myriads) are normal suits ranked 987654321
  • Dragons and winds are put together in a suit of “specials”
    • The special suit cannot be used to form straights
    • but for tiebreakers, specials are ranked higher than pip cards:
      1. Red dragon
      2. Green dragon
      3. White dragon
      4. North wind
      5. West wind
      6. South wind
      7. East wind
      8. Pip cards 9-1

Although the probabilities of each hand will be different, The probability ranking will be the same. 4-of-a-kind will be more rare than full house etc.

Additional Clarification: Like in poker, sets (pairs, triplets, etc.) can mix suits.
