In order to provide players with the best, most fun and still the most bias-free online gaming experience, online casinos utilize Random Number Generators (RNG). Thanks to them the outcome of every game is arbitrary and it is not affected by the previously picked numbers or any other factor. Proper virtual casinos have their RNG regularly checked by authorities which deal with ensuring a fair online gambling. Such regulatory companies include eCOGRA, iTech Labs, Technical System Testing (TST) and a few other agencies.
