Re: [vpFREE] Pseudorandom number or just random - is there difference



Slots and VP use "pseudorandom" number generators, which use a mathematical function to generate the numbers used to decide which cards come up in VP, or which payout you get in slots. The math function has to be carefully designed to give numbers that are, by various mathematical tests, essentially random. If the function is not properly designed, it can give non-random numbers

A true random number generator has to use physical processes that are not predictable. For example, you can use radioactive decay, or "white noise" in the atmosphere. See https://www.random.org/ for the latter.

If done properly, a pseudorandom generator (PRNG) is as good as a true random one for gaming purposes.

The Wired article that was linked here by nightoftheiguana is interesting, because it shows what happens if the PRNG is not well designed - which the hackers were able to determine because they had access to the software. There was a similar case where a player figured out that the PRNG in a video keno machine was reset every day and had predictable number draws at the start of each day, but he wasn't cheating - he did nothing to the game or use any computing tools.

I seem to remember reading, I think, VP random referred to as pseudorandom number generator.  Maybe I am remembering wrong.  Is it correct term, does it exist as the term or is it different than random as in a live

deck of cards as opposed to electronic deck of cards?
