It's a rework of guess who? to play with cards in this version of guess who? players place their cards with the characters in front of them and choose a mystery character from the deck of mystery cards. Subsequently, each player, in turn, asks his opponent a question whose answer can only be "yes / no" which will help him find out who the character of the opponent's mystery card is. When a player believes he knows who the mystery character is, he reveals it. If he guesses correctly, he wins, if he misses, he loses. This quick version of guess who? it is perfect for entertaining your children while traveling or at a friend's house.
