Online poker sites that are legitimate and have passed through third-party scrutiny are NOT rigged. But some players won't believe this, and feel they are being cheated over issues such as: Too many bad beats. More pots being won by depositing players (to encourage new players)

Most people only talk about it being rigged after a big losing session or a bad beat in a tournament. The fact that so many online poker players have made hundreds of thousands, or even millions of dollars playing the game, proves that the games are not rigged.

Poker is a family of games that exhibit imperfect information, where players do not have full knowledge of past events. Whereas many perfect-information games have been solved (e.g., Connect Four and checkers), no nontrivial imperfect-information game played competitively by humans has previously been solved.

There is some evidence that professional poker players tend to have higher than average IQs, though poker skill involves multiple factors beyond raw intelligence: A study of young poker players found their mean IQ was 112, compared to a norm mean of 100. Players identified as "experts" had a mean IQ around 120.
