About This Slot

Following is a respresentation of the 21 Bell Slot Machine, © 1973. A mathematical analysis of this slot can be found in my slot machine appendix 5.

My source for the design of this game is Brett Niver of Kent State University. My brother found the design as part of one of the professor’s homework assignments. Professor Niver credits John Scarne, Scarne’s New Complete Guide to Gambling, New York: Simon and Schuster, 1974, as the original source.
