Thanks, Jean! You picked up on my unwritten assumption, which is that it is
just about impossible to hit the DRAW button at the EXACT same moment for two
different holds. Even a millisecond difference would certainly give
different draw cards, considering the speed of microprocessors these days.

That's the whole point. As fast as the cards are shuffling, it is
unlikely - probably highly improbable - that you would choose one hold over
another and hit the "Draw" button at EXACTLY the same time. In your
example, you would use slightly different arm/finger movements to hold one
pair or the other. I stick with Brian on this point.

Thanks, Jean! You picked up on my unwritten assumption, which is

that it is

these days.

I agree. I figure a shuffle (RNG cycle) takes about 1/100 of a
millisecond. If you could hit the draw button within 10 milliseconds
for different holds (and that's pretty good), it would allow 10,000
shuffles to pass.

PS. I ran a test on my old PC with a 1 mhz processor and the number
was around 1/1000 of a millisecond for the RNG I tested. I assume a
Vp machine has a slower processor.

Hi Dick,

The actual RNG algorithm used is a trade secret of IGT's (and Bally and Aristocrat and WMS and everyone else) so we can't know for sure what the cycle time of the RNG is. However, as I wrote to Bob that isn't the critical factor, you also have to consider what the odds of hitting an equivalent point in the RNG cycle are.

And you are wrong about the processors. If you look at the graphics on the latest machines, both VP and video reels they are using the latest and fastest processors available. They are significantly faster than your poor old 1 mhz dinosaur. The only manufacturer that lists the processor is WMS that says the latest platform uses a P-IV with 2 GB RAM. They don't list the speed but...

If some of these games don't already use dual- or quad-processors they will within the year.

Hope this helps,

Bill

Bill, sorry about my typo. I meant 1 Ghz (not mhz) but without an
edit capability I usually don't correct my posts. The last I heard
IGT was using 200 mhz but you are probably right and they have
upgraded to something faster. However, some of the older machines (3-
4 years old) will likely have this processor.

In addition, I know the RNG is a trade secret but I doubt it is
substantially different from the current set of RNGs available
online. I tested two different RNGs and got almost identical numbers.
However, if anyone can give me any additional details I can go back
and change my program to account for the differences.
