Random Number Generator
All of our games, with the exception of Live Casino games, use a Random Number Generator (RNG) to determine the outcome of every hand or spin. The outcome cannot be influenced by any external factors, including ourselves, in any way.
Every 3 months, the leading independent and internationally approved testing agency eCOGRA conduct an audit of all bets placed on our RNG games to determine the Return To Player % (RTP).
You can find those results here.
Frequently Asked Questions
What dos RTP (Return to Player) mean?
A Return to Player % indicates how much a game should pay out over a long period of plays.
If a slot has a stated RTP of 93%, you can expect this game to return 93p for every £1 wagered.
Seem like a pretty raw deal? Not in the short-term – results can swing wildly in either direction during any individual session.
How is RTP Calculated?
The RTP is calculated on the results of millions (or even billions) of game rounds.
You can work out your own RTP using this simple formula:
Wins / Wager x 100
For example, you wager £100 on a game that returned £90, so you’re £10 down overall:
90 / 100 = 0.9 x 100 – gives you an RTP of 90%.
If you wager £100 on a game that returned £110, giving you a £10 profit:
110 / 100 = 1.1 x 100 – an RTP of 110%

Why Have I Won Less Than The Advertised RTP%?
The RTP isn’t the best indicator of how much you can win in a single playing session. Instead, a game’s RTP is a measure of all wagers from all players pooled together, over time.
You may have a good day on one slot, but someone else could have had a bad one – or vice versa.
The longer you play a particular game, the closer it should get to its theoretical RTP. But like we said, this is over a very long period of time - think months not minutes.
As with all gambling, if you’re starting to feel frustrated or find yourself chasing losses, consider giving yourself a break, setting deposit limits or self excluding Here .
Only ever bet with money you can afford to lose.
What does RNG mean?
RNG stands for Random Number Generator.
It’s a mathematical construct used to generate a random set of numbers which, when applied to casino, could translate to a cherry on the reels, a red on the roulette wheel, or an ace in your hand.
RNGs are just the modern application of randomness devices that have existed since ancient times such as dice, shuffled cards, a coin toss, drawing straws, etc.
They ensure the randomness and fairness of all our non-live games.
Frequency of Feature/Bonus rounds in Casino games
Almost every casino player has asked themselves this question at some point.
You might hit the bonus on your first spin one day, then play hundreds of spins the next day without the feature hitting.
This is due to the random nature of casino games, and there is no guarantee of a feature hitting over the course of a single playing session. It’s also true that previous results hold no bearing on the next spin/round, so you could hit a feature multiple times in a session.
Nobody knows when a feature will hit, but when you gamble responsibly, it’s all part of the fun.
Are Live Casino games fair?
All Live Casino games on Parimatch are supplied by licensed providers. The games take place in controlled environments which are regularly audited to standards approved by the regulators. This includes monitoring of all equipment used (Roulette wheels etc). Some games also use an element of RNG (deciding multiplier amounts for example) which are also tested and certified in the same way a slot game is.
Live Roulette – valid spins?
According to procedures, a valid spin is full 3 revolutions starting from the release point in the wheel rim until the point when the ball leaves the wheel rim. If the ball rattles in the wheel, but still made 3 revolutions in the wheel rim (not counting the rattling) the spin is considered as valid.
If the ball leaves the wheel rim, hits the diamond, and comes back into the wheel rim this game is not considered valid. If the dealer takes the ball and prepares to make a spin however do not make a spin for some time, this spin is deemed valid if the ball made 3 full revolutions.
