Its the Guess Who? game, the original guessing game! Each player chooses a mystery character and then using yes or no questions, they try to figure out the other players mystery character. When they think they know who their opponents mystery character is, players make a guess. If the guess is wrong, that player loses the game! Players can also challenge opponents to a series of games in the Championship Series, where the first player to win 5 games is the Guess Who champion.
