oker rooms generally use software algorithms – typically based on the computer’s clock – to generate 52-card ’shuffled’ decks. This, however, does not come even close to representing the outcome of real-world shuffles.
In real life, there are 52! (that is,
10,783,978,666,860,260,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 . . . give or take) unique shuffles possible. That’s 10.8 novemdecillion.
Online, however, several factors reduce the number of possible shuffles. A 32-bit processor, for instance, is limited to generating 32-bit seeds . . . only 4.2 billion of them. This is a considerable reduction from the above figure. 64-bit processors can generate 18.4 or so quintillion unique numbers, still a far cry from a human dealer.
The useage of a system clock to seed a number sequence further reduces the number of possible unique shuffles; there are only so many milliseconds (just over 86 million) in a day.
Cigital, Inc. noted the above, and – taking an algorithm widely used less than ten years ago – showed not only how limited online shuffling was at the time, but was itself able to repeatedly predict which of the limited card shuffle sequences was in use for any round if five cards were visible.
Muffy, it would appear, had a point.
