my best mates brother has just been sponsored by pokerstarshe gets 50k a month to play any tourneys he wantsa at the end of the month he gets a percentage of winnings. how many others are doing the same thing for pokerstars how can this make it fair in anyway, there all cheats ipoker software the worse.

It seems like what deez was talking about would most likely work the best. Either that or what Jed has said.

@MRE

Just use base 6, and have the 6′s represent 0.

If you wanted a random number from 0-1295, just roll 4 dice. 3526, would be 3520 in base 6 or 840 in base 10.

Well, that is an awkward typo.

I have a true RNG set up. It collects Wi-Fi raw signals, audio line-in noise, thermal data, dick IO, Intel’s on-chip random number generator, and radio noise, as well as Linux’s built-in PRNG. It’s pretty much impossible to predict.

“who the fuck is complaining about the quality of the random numbers?”

Obviously, the losers.

Pedro i am talking about with nothing plugged in, highly amplified analog inputs make noise by themselves from electronic noise of transistor junctions etc, the crappier the circuit (onboard audio) the better.

how about a diy version of something like this?

@deez – exactly the concept on which craps is based. Snake-eyes and double six are quite hard to roll, thus the take is quite high. 6 and 7 ‘any way’ (1 and 5, 2 and 4, 3 and 3, etc) is pretty easy (common), and thus the take is low.

@blue – another method that amounts to the same thing is to say that the first die represents a row and the second the column on a 6×6 table, in which the numbers 1 to 36 are filled in.
Each die adds a dimension, so 3 dies yields 216 numbers, etc. This could get pretty cpu intensive to maintain the look-up tables as you add successive dies (dimensions)
removing the idea that the die itself represents a random number and instead represents an *indexing component* to a number should give flat results (as you say).
But as everyone else pointed out, quality of the die affects it quite a bit.

As no-one’s mentioned it yet: collecting entropy from your laptop’s wireless receiver is quite hard to duplicate.

deez, you only need two dice to represent every number from 1 to 36 if you use each dice as one “bit” in a base-6 number system. So just let (1,1) represent 1, and count up from there to get to 36. I am pretty sure since each bit has a nice flat distribution, then the whole range 1-36 would also have a nice flat distribution.

This is a joke – but a good one. Useless but nice machine. I imagine that the main point of it is to entertain the web site users, or to make people talk about it.

Generating good random numbers is not that much a problem, it has been widely investigated by crytologists: there exists robust and efficient algorithms.

There also exist simple ways to get “real” random: recording white noise, taking least significant bits, for example.
