Pick a curtain!
For example, I'll pick 3.
The person below me gets to choose what I won (a prize or a fake prize)
playerone: I pick curtain 2
playertwo: Sadly, you got a dirt mound.
I pick curtain 3
playerthree: You won 3 curtains!
I pick curtain 2
Keep going! You can give the person either a good prize or a false prize.
I pick Curtain 1
