Challenge other players to dispute a word. If you think that a player has played a word that does not exist or that another player has misspelled a word, then you can challenge that player. When you challenge a player, you look up the word in the dictionary.[11]
If the word is in the dictionary and the player has spelled it correctly, then the word stays and the player gets the points. The challenger loses his or her turn.
If the word is not in the dictionary or the player has spelled it incorrectly, then the player must remove the word from the board. The player gains no points and loses that turn.
