Bet who can do the task best, and then Prove It! There are four categories: Mad Skills (use your skill!), Know-How (use your noggin!), Fingers Crossed (its all about luck!) and Buddy System (teamwork!). For example, a card may read, Bet how far you can launch a card, flicking it finger-football style! Now the two competitors bet back and forth until one person ends the betting by saying Prove it!, and now the other player must perform the task to get the point!
