What Is RTP? Return to Player Explained
RTP, or Return to Player, is the percentage of all wagered money a slot or casino game is designed to pay back to players over the long run. Here is what it really means.

RTP stands for Return to Player. It is a percentage that tells you how much of the total money wagered on a game is designed to be paid back to players over a very large number of spins. A slot with an RTP of 96% is built to return R96 for every R100 wagered across millions of spins — with the remaining R4 representing the casino's long-term margin, known as the house edge.
RTP is a theoretical, long-term figure. It does not predict what will happen in your session. Over a few hundred spins you might win far more than 96% or lose your whole balance, because results are random. RTP only describes the average behaviour of the game over an enormous sample.
RTP vs house edge
RTP and house edge are two sides of the same coin. House edge is simply 100% minus the RTP. A game with 96% RTP has a 4% house edge; a game with 92% RTP has an 8% house edge. The lower the house edge, the better the long-term value for the player.
Because the house edge is built into every game, the longer you play, the closer your results tend to drift toward the theoretical RTP. This is why no betting system can overcome a negative house edge in the long run.
What is a good slot RTP?
Online slots typically range from about 92% to 97% RTP. Anything at or above 96% is generally considered player-friendly. RealTime Gaming (RTG/SpinLogic) slots — the engine behind Apollo Slots — commonly sit in the 94%–96.5% range, with the published figure varying by individual title.
- 97%+ — excellent, among the most generous online slots
- 96% — strong, a common benchmark for fair value
- 94–95% — average for many casino slots
- Below 92% — below average; the house edge is comparatively high
How RTP is calculated and audited
RTP is determined by a game's mathematical model — the symbol weightings, paytable and bonus features. Independent laboratories such as iTech Labs, GLI (Gaming Laboratories International) and TST audit this model and the Random Number Generator (RNG) to confirm that real-world results match the advertised RTP over millions of simulated rounds.
Reputable casinos publish or provide the RTP for their games on request. If a game's RTP is impossible to find anywhere, treat that as a small red flag.
How to use RTP when choosing games
Use RTP as one input, not the only one. A higher RTP improves your expected long-term value, but volatility (how the wins are distributed) often matters more to how a session actually feels. Pair this guide with our volatility explainer to choose games that match your bankroll and playing style.
- Compare RTP between similar games before you play
- Remember table games like blackjack often have higher RTP than slots
- Treat RTP as a long-term average, never a session guarantee
- Combine RTP with volatility and your budget to pick a game
