RISK! Unit 1 Review

The Rules … • You will be playing against your partner – whomever has more money at the end of the game wins! • After a problem appears on the board, you have 3 seconds to record your bet. • Solve the problem – on your own! • After a few minutes, I’ll show the answer. If you got it correct, add the amount you bet to your total. If you missed it, subtract. • You’ll be keeping track of your own total – keep your partners honest! You’ll all start with $50. You can bet in increments of $20. You must bet each time (even if you’re in debt).
