The Answer Champ Game
is a fantastic and fun way to review>
In general, after moving to your first match up position, two players or teams will vie to answer the question you'll now introduce by clicking on one of the black question buttons. The player or team that responds first gets to answer the question. This might be determined by the first player to raise their hand, sound a noise maker that you've provided, or slam a wireless buzzer device. If they answer correctly, in rounds with just one question, they advance (click on name box itself to advance team/player) to the next round.
