More Dice Fun: A while back I wrote about a maddening but interesting book called Scarne on Dice. It's a really huge book which I intend to get rid of ASAP, but before I do there's a couple things about dice, and cheating at dice, I wanted to quote.

In perhaps the most entertaining section of the book Scarne takes on the sleaziest parties in this whole wretched business, "the crooked gambling supply houses", who sell outdated cheating devices at huge markups. According to The Big Con: The Story of the Confidence Man, another book I read recently, the mailing lists of these supply houses were coveted by con artists, because by definition, everyone on those lists "liked the best of it." One catalog's advice to buyers, according to HoyleScarne:

When telegraphing use the following code: PAINT for cards and CUBE for dice.


This head-slapping entry from Scarne's inventory of trick dice needs to be quoted in full:


These are a very brazen brand of mis-spotted dice that show 7 or 11 every roll. Since the catalog lists them, there apparently are buyers, but they are strictly for use on very soft marks and then only on dark nights. One die bears only the numbers 6 and 2; the other nothing but 5's! Since anyone but a blind man would tag these cubes as mis-spots, the moment they rolled out, they are of no use except for night play under an overhead light when the chumps can't see anything but the top surfaces of the dice. Strictly for use by cheats who don't know what a real set of Tops is.

There's a a couple entertaining but long stories of specific cheats which I won't transcribe. The best is the story of "the mouth switch". Seems there was a craps hustler in the 30s who kept a trick die in his mouth and introduced into the game it by cupping the dice in his hands and "blowing" on them. They called him "Mononucleosis Joe". Actually they called him "The Spitter," but they only started calling him that after he tried this trick while drunk and ended up rolling all three dice onto the craps table.

Finally, a tale of collegiality which I feel gets really boring if you explain what the numbers mean:

Several years ago the Harvard Computation Laboratory put a battery of calculating machines to work and came up with a whole book full of answers. Since the binomial formula is used in many problems and so often requires staggering amounts of arithmetic, they constructed a set of Cumulative Binomial Probability Distribution Tables which give provability fractions for a wide range of values of n, r, and P. And because Dr. Frederick Mosteller, Chairman of the Department of Statistics, had seen a copy of Scarne on Dice and was aware of the 26 game problem, he saw to it that the calculating machienes were asked to provide figures for the terms n = 130 and P = 1/6.

It's easy to read this book and feel superior to the people who get fooled by seemingly rudimentary tricks (David Maurer, author of The Big Con, specifically points this out in his book), but I'm sure someone who knew their stuff could take my entire roll in a crooked dice game. Why am I so sure? Because you could take my entire roll in a completely fair dice game.
