How to Play
1. Every team begins with $50.
2. A category will appear on the screen. Your team must wager money based on your knowledge of the topic. You cannot risk more than half of your money at a time.
3. As a team, you will solve the problem. If you get it right, you receive the money you risked. If you get it wrong, that money is taken away. Record this on your chart.
4. The team with the most money at the end of the period wins!
**Good Teamwork is Rewarded**
