There's an infinite number of other options.

One possibility, the host only opens a door with a goat when you have chosen the one with the car. (The best strategy would be never to switch and end up wining 1/3 of the time.)

Another? The host only does so when you have chosen one with a goat. (The best strategy would be always to switch when offered the chance and end up wining every time.)

Another, the host does so 3/4 of the time when you have chosen one with a goat and 1/4 of the time when you haven't. (The best strategy would be always to switch when offered the chance and end up wining half of the time.)

Another, the host does so ever time if it's Monday, Wednesday, or Friday and uses option 1 on Tuesdays and Thursdays. (The best strategy would be to know what day it is and use the appropriate strategy from above.

And so on ...

Without that additional 'clarification' a
contestant would be inconvenienced/confused
HOW?????

In the most fundamental of ways--not knowing the best strategy! (Of course, I don't think anyone promises game show contestants that they will know the best strategy.)

get real!

I thought I was getting real!
