Created by @gregatku for use in Coding Classes for Kids Unlimited. Simulates a TV Game Show where the big prize is behind one of 3 doors. You get to pick one, after which the host reveals a door you didn't pick, with a dud prize. You are offered the chance to stay with your original selection or switch to the other closed door. On face value it seems like a 50-50 chance so it shouldn't matter, but things aren't always what they seem. Play lots of games to see for yourself.
