A domino is played in error

When a player plays the wrong domino, it is called a misplay. If a player misplays for example, joins a 2 to a 3 and it is discovered before the next player makes his play, he must restore the misplayed tile to his hand and play a correct tile. If a player misplays and no one notices until after the next play has been made, the wrong tile is considered played and cannot be replaced with the correct tile. If a score is realized on the undiscovered misplay, the player is allowed to keep it. If it is not a misplay, once a tile is played and a player takes his hand off the tile, it may not be taken up by the player.
