Click the 20 doors button to pop up 20 balls, one of which is hiding a car! Pick your first ball. Then all the balls other than your ball and another one will disappear. Ones of these had the car behind it the whole time. Do you stick with your gut, or pick the other door?
You pick the other door. There is a global variable to track how many time a player has picked the car on their first choice, whether or not they chose the other ball. I'll add something to keep track of that later, it's 2:30 in the morning.
