Monty Hall Dilemma - 3 Doors Game

This is a simulation of the Monty Hall Dilemma. Press the start button. At this point, the surprise will be randomly hidden. The game starts off with three closed doors. Only one of them hides a surprise, while the others are empty. After you choose one of the doors, one of the other doors will be revealed as empty. Your next choice is between your first pick and the other remaining closed door. Which one will you choose? Which odds are better to pick the surprise?

When the game is over, press start to play again. Your results will be summarized, so you can track the probabilities of either staying or switching.

There is also a set of "Cheat" text boxes at the bottom of the window. Only check off "Cheat" if you want the location of the surprise to be revealed in the text boxes. Of course, if you're cheating, the probability results will not be accurate. It's only there to prove that the game isn't fooling you and moving around the surprise in the middle of the game.
