According to the Scrabble Official Rulebook, a word may be challenged by another player by checking a previously agreed upon dictionary. Once a word has been played, the challenge must occur before the score is added up and the next player starts their turn. If the challenged word is found to be unacceptable according to the dictionary, the player who played it must take back their tiles and loses their turn. Note that while players may consult a dictionary during a challenge, they are not permitted to use a dictionary to search for words to fit the tiles on their rack during regular play.
Step-by-Step
Step 1: A player plays a word on the board.
Step 2: Another player identifies the word as invalid and declares a challenge before the current player's score is tallied.
Step 3: The challenger consults the pre-agreed dictionary to verify the word.
Step 4: If the word is invalid, the player who played it removes the tiles and loses their turn.
Example Play Situation
Alice plays the word 'ZAX' on the board. Bob suspects it is not a valid word and challenges it before Alice adds her score. Bob consults the agreed dictionary and finds 'ZAX' is not listed. Alice must remove her tiles and her turn is forfeited.
