Call My Bluff

In Call My Bluff, one player creates a secret five-letter word, then the other player takes turns guessing letters in the word as well as whether they're in the proper location, similar to Mastermind. But while one player is guessing, the word creator is secretly listing words that can be created from the letters in the goal word. After guessing that word, the guesser then has a set amount of time in which to create a word list of their own. Whoever has the longer list wins.
