  The Pseudo-Random Number Generators (PRNGs) are key tools in Monte Carlo
simulations. More recently, the MIXMAX PRNG has been included in ROOT and Class
Library for High Energy Physics (CLHEP) software packages and claims to be a
state of art generator due to its long period, high performance and good
statistical properties. In this paper the various statistical tests for MIXMAX
are performed. The results compared with those obtained from other PRNGs, e.g.
Mersenne Twister, Ranlux, LCG reveal better qualities for MIXMAX in generating
random numbers. The Mersenne Twister is by far the most widely used PRNG in
many software packages including packages in High Energy Physics (HEP), however
the results show that MIXMAX is not inferior to Mersenne Twister.
