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.
You can play real money Sit and Go poker tournaments at PokerStars across a wide range of formats, variants, and buy-ins. These tournaments start when the correct number of players have bought in, from only two up to 180.
The tournament prize money gets divided based on the number of players and the amount in the pot. The unfortunate truth is that most players will not get paid. You must finish within a certain percentage of the entire field even to make a min-cash in other words, the least amount of money you can win.
