This is a game of numbers, probability, risk-taking, and very basic climbing animations. It's a fun game of chance for you students to take turns playing.
Press the spacebar and make the climber climb between 1-10 steps. If he climbs beyond 21 steps, game over! The winner is the student who can get the closest to 21 without going over! This is one of those games that students will be on their best behavior for the opportunity to play.
