In the card game "Whooo?" you have to determine whose face is the last one shown on the card. You will use word hints to find out your opponent's cards.
When it is your turn, you will have the opportunity to interrogate your opponent with a multiple-choice question that has four possible responses. Consider the people who are still playing the game with you and select a question that will allow you to get rid of the most cards. If there aren't any interesting questions, you can try using one of your golden keys to rewrite the questions. When you are down to your final two cards, try to guess which card your opponent is holding. After completing a set of matches, you will have the opportunity to spend your keys to unlock objects in random order. These can either be new characters or power-ups for use during tournaments.
To guess the card, use the left mouse button.
