Random Card Generation


Zynga Poker prides itself on being a fair and trusted gaming platform, which is why the card dealing algorithm, or Random Number Generator (RNG), utilized in our game is certified by Gaming Laboratories International, a leading independent certification agency for the gaming industry.

In a game like Poker, the order in which the cards are dealt is critical. The RNG algorithm used determines the sequence in which cards are drawn from the deck. By using a certified RNG algorithm, Zynga guarantees that this sequence is random and thus, the outcome of the game is random and does not follow any pattern.

Ensuring an authentic poker experience is of the utmost importance to our team.  Official certification of our RNG to ensure fair dealing is just one of the many steps that we are taking to provide the best poker gameplay experience possible.
