Clothespin Arithmetic

I like to play games. One of the many games that I enjoy playing I call clothespin arithmetic. It's a simple math game of addition and subtraction and it goes a little something like this -

I blindfold the submissive and apply a number of clips somewhere on the body. Then I remove the clips in various fashion and the submissive is to guesstimate the number of clips they think there might be left dangling. Wicked laughter ensues. If they guess the correct number of clips left, they win a prize. If they guess wrong, well...they still win a prize. It just may not be the prize they want.
You get the idea. *wink*
