Random Number Generator

 Which RNG does GamesGrid use? 
Mersenne Twister (MT) is a pseudorandom number generator developed by Makoto Matsumoto and Takuji Nishimura (alphabetical order) during 1996-1997. MT was designed specifically for Monte Carlo simulations, to overcome the flaws found in previous generators. It has far longer period and higher order of equidistribution than other generators: the period is 219937-1 (approximately 4 followed by 6001 zeros), and 623-dimension equidistribution is assured. Period is the number of occurrences before the sequence repeats; the huge period of the MT generator means that for practical purposes, the sequence never repeats. Equidistribution means that every sequence of 623 (or fewer) numbers is guaranteed to occur with the correct frequency over the period of the generator; in practice, this means that every shuffled deck will be random. More information may be found on the MT home page. A slightly more readable version may be found at wikipedia.org. MT is one of the few RNGs that passes the independent DIEHARD and ENT randomness tests. Some test results are available at the randomizer site.
