WRONG NUMBER OF TILES (Article 205)

Commentary: The League states that 13 tiles must be “in or on” a player’s rack at all times, with the normal exception of temporarily having 14 tiles during an active turn. This rule establishes the required composition of the hand; it should not be interpreted to mean that every tile must physically touch the rack during every moment of normal game procedures (Article 168).

During the Charleston Phase

Sometimes North—the player to East’s left—is short a tile because they forgot to take their 13th tile during the deal. If the error is discovered before East discards to begin the pick-and-discard phase, North may take the missing tile and the game continues. If it is discovered after East’s first discard, another player may disqualify the hand. If more than one player has the wrong number of tiles during the Charleston, all tiles are thrown in, and a new game begins.

The 13-tile requirement should not be applied literally to moments when tiles are being passed or rearranged. Those tiles are temporarily in motion as part of normal play.

During the Pick-and-Discard Phase

Tiles may temporarily be off the rack while a player performs normal game procedures, such as rearranging tiles or completing one or more joker exchanges. These moments should not be confused with having a hand containing the wrong number of tiles. What matters is whether the player has the correct number of tiles when the procedure is complete.

For example, exchanging two natural tiles for two jokers during the same turn does not create an 11-tile hand simply because two tiles are temporarily off the rack. The player is completing permitted exchanges rather than playing with an 11-tile hand.

League Clarification: In August 2026, a player contacted the NMJL directly for clarification about exchanging multiple jokers during the same turn. The League confirmed that multiple joker exchanges may be made together and do not need to be completed one at a time. Tiles temporarily removed from the rack while completing the exchange do not constitute a wrong-number-of-tiles violation and are not grounds for disqualification. Tournament directors may establish additional procedures for their events, but those should be understood as tournament-specific requirements rather than League rules.

Likewise, a player may pick a tile with one hand and discard with the other while the picked tile is still being held. The tiles are in motion during a normal pick-and-discard procedure. If the completed turn leaves the player with the correct number of tiles, the hand does not have an incorrect tile count.

If a hand actually contains the wrong number of tiles during play, another player may disqualify it. Because players cannot disqualify themselves, a player who recognizes their own error continues playing until another player intervenes. Once disqualified, the player stops picking and discarding. Jokers in valid exposures made before the disqualification remain eligible for exchange.

When a player has the wrong number of tiles during the play, they can be disqualified by another player (Article 24). Since a player cannot disqualify themselves, they should discard to block opponents from winning. When they are disqualified by another player, they stop playing and do not discard. Valid exposures with jokers are available for exchange.

Question from a Player: When a player picks a tile and discovers that they have too many tiles, do they discard the picked tile?

Answer from the NMJL:  Should a player’s hand contain the wrong number of tiles after East has discarded the first tile, or if an incorrect number of tiles are exposed, the player’s hand is “dead”. Mah Jongg cannot be called. The “dead” hand ceases to pick and discard but will pay the winner the full value of the hand. A player should not declare their own hand dead. It is up to other players to declare a hand “dead.”
