likewise it is easy to make a mistake and add both bias or non-
whiteness. The bits, 6
(2^6 = 64) or 32, or whatever have no real impact. 32-bits is not
MORE random than 6
bits, etc. The resolution has nothing to do with "randomness" at
all, so long as there are at
least 1 bit.
Yes and no. No pRNG is really random and that is what I assume IGT
uses. So one of the most important aspects is making it difficult to
detect the algorithm. While fewer bits can still be "random", it
takes more bits to impede hackers.
Also These kinds of random numbers are always band limited, and so
not truly white ("flat
DC to Daylight" as I like to say). The key is to make sure numeric
artifacts don't f-things
up, espcially binning or rounding. Finally, the requirement
for "whiteness" is not so
restrictive as the requirement for bias. That is a slightly
positve biased mean (higher EV)
could be a big problem for the casino, while a non-biased mean but
slightly non-white
distribution would not be a big deal.
Agreed. The overall entropy added by arbitrary key presses eliminates
almost all problems except a positive bias or a genius hacker.
