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.

In reality, the RNGs used by online poker sites come as close to real randomness as possible, simulating random outcomes by running through millions of card combinations per second.

PokerStars has one of the best bot and collusion security prevention teams in the industry. They take this very seriously. But of course whenever there is money involved in anything in life, people will try and cheat. So it doesn't stop people from trying to run a bot on PokerStars.
