The integrity of the shuffle

We deal the cards in a fair and honest manner. Once the deck is shuffled, it is set, and the order in which the cards are dealt cannot be changed. The software that shuffles and deals the cards cannot control who wins and loses; it just deals the cards, and the rest is up to the players.

Our software produces a random shuffle that favors no player over any other. The methods we use ensure complete randomization and complete unpredictability of the cards to come. You can read more about the description of these methods by going to the Integrity section of our website.

We arranged for Gaming Laboratories International to review our shuffle. They are a widely recognized independent gaming product testing laboratory. Their investigation found the shuffling to be fair and random. To read further, go to the Random Number Generator page of our site.

This information is also described in one of our videos called How does PokerStars shuffle the deck?

We encourage you to review your own hand histories. Why not perform your own analysis using widely available poker tracking software? We have dealt over 200 billion hands and freely give real money hand histories anytime someone requests them. Whenever you want, we can send you a copy of every single real money hand you've played.

Other investigations carried out by third parties have also concluded that our cards are randomly shuffled. Many who have conducted such studies have posted their findings to the Internet.
