Mahjong Joker Rules

Jokers are wild tiles, but they cannot be used everywhere.

Important joker rules include:

  • Jokers may replace tiles in a pung, kong, quint, sextet, or larger identical grouping.

  • Jokers cannot be used in pairs.

  • Jokers cannot be used in Singles and Pairs hands.

  • A discarded joker cannot be called.

  • Jokers should not be passed during the Charleston.

  • An exposed joker may be exchanged for its matching natural tile.

  • The player exchanging for a joker must use the joker in their own hand.

  • You may exchange for a joker when it is your turn or when another player has made an exposure.

Understanding joker rules can prevent illegal hands and help you recognize valuable exchange opportunities.
