A Guide To Casino RTP Percentages

In the world of online casinos, RTP is arguably the single most important mathematical statistic a player can understand.


Standing for "Return to Player," this percentage dictates the mathematical generosity of any given casino game.

What Exactly Does RTP Mean?

It is a statistical calculation based on millions, or even billions, of simulated spins or hands.


The remaining 4% is kept by the casino, representing their guaranteed profit margin, known as the house edge.

Understanding the Difference: RTP and Volatility

RTP dictates how much money is returned overall, but "variance" or "volatility" dictates exactly how that money is distributed.


A low variance slot will pay out small amounts very frequently, keeping your bankroll highly stable.

Maximizing Your RTP Advantage

Most modern software developers are legally required to list the RTP directly within the game's information or help screen.


As a general rule, avoid playing any online slot machine that offers an RTP below 95%.
