Welcome to the most spectacular game show on the planet! You now have a once-in-a-lifetime chance of winning a fantastic sports car which is hidden behind one of these three doors. Unfortunately, there are only goats behind the other two doors. Select one to make your choice!

Are you sure about that? You can still change your mind and select a different door…

I’m sure!

A great choice, but let me make life a little easier for you. I’ll open one of the other doors with a goat, so that there are only two doors left for you to pick from. Do you want to stick with your choice, or do you want to swap?

I want to stay!I want to swap!

Ok – let’s see how you did…

Open the doors…

Looks like you made the right choice. Congratulations, you just won a beautiful new sports car! Sorry – it seems like this time you only won a goat. But don’t worry, you can play again!
