The term 'Rhyming Word Game' refers to two popular word games, Crambo and Hinkypinky. Crambo is a game in which players take turns trying to guess a word based on a rhyme given by another player. Hinkypinky is a game in which players take turns giving clues to a word that rhymes with the clue given by the previous player. Both games are fun and engaging for all ages, and can help improve language skills.
