Lego Masters producer Endemol Shine North America and Hasbro’s eOne are developing a game show based on Guess Who? that has been in the works since 2019. "In each episode, contestants make snap judgements based on intuition and clues in an effort to win cash prizes, according to Deadline. "In the original guessing game, each Guess Who? player chooses a mystery character and then, using yes-or-no questions, tries to figure out the other player’s mystery character. When they think they know who their opponent’s mystery character is, players make a guess. If the guess is wrong, that player loses the game. Players also can challenge opponents to a series of games in the Championship Series, where the first player to win five games is the Guess Who? champion."
