The following are simple tests that can be run on a large sample size and would more than satisfy anyone sane (some people will never be satisfied, they lose and don't want to accept it).

1. Preflop card distribution

Every hand you get cards and in say 100K hands you have a really good sample and you know how much you are "expected" to have of each type of hand (AA, KQs, J4o, etc.)

I only have 50K or so hands in my PT database but the distribution is near statistically pefect. Obviously there are deviations but nothing whacked out.

2. How often particular draws come in

When you flop a 4 flush and stay in for turn/river how often do you make your flush? When you flop an OESD and stay for turn/river how often do you make your straight? etc.

This can be done with fancy SQL on a PT database but I'm too lazy.

Obviously these are simle checks but would effectively prove a random shuffle.

And since everyone thinks every site is rigged, you'd probably have to repeat this test on every site.
