The Gambling Commission describes percentage RTP as the part of the money paid to play a machine that is then given back to players as prizes. For slots, RTP describes the payout percentage the game is designed to return to players over the long run. This guide explains why the same slot title can show a different RTP at different casinos, and how to check the live figure before you spin.
What RTP Means and How It Is Measured
A published RTP figure is an average achieved over a significant number of game plays. It is not a return that is paid back every time you play the game. A 96% RTP slot, for example, is built to return about $96 for every $100 wagered across a very large sample of play. The rest represents the casino's expected edge.
- The Gambling Commission gives measurement examples for gaming machines. Average %RTP is generally measured over 10,000 or 100,000 games for compensated machines. Random machines need more games, depending on their category. Compensated machines are also random, but their prize chances vary with earlier results. This classification is separate from the online RTP versions discussed below.
- If a gaming machine displays an 85% RTP, a player should not expect to win an average of 85 pence for every £1 staked during a single playing session.
- House edge measures the percentage a casino would expect to keep, on average, from each hand or spin, given normal patterns of play.
Why the Same Slot Can Show Different RTP Numbers
Providers set a slot's RTP during development. They run computer simulations that replay millions or even billions of spins based on the game's paytable and rules.
Hacksaw Gaming lists Wanted Dead or a Wild with RTP options of 96.38%, 94.55%, 92.33% and 88.42%. These are the choices published for this game, not a confirmed setting at any particular casino. Use that example as a reason to check the game you open, rather than relying on its name alone. Compare the figure shown at each casino before deciding where to play.
How to Check a Slot's RTP Before You Play
Start with the slot you want to compare. Work through the checks below before placing a bet. Keep the exact game title and the casino name beside your notes, so you do not mix up the versions you have checked.
- Open the slot and look for its info or help menu, often marked by an i icon. That menu shows the paytable, the rules and the RTP percentage.
- Some slots have more than one RTP version. The in-game info panel is the most reliable way to confirm the RTP of the version you are actually playing.
- Check the full game title before comparing your notes with a review or another casino. Do not treat a similar name or matching artwork as confirmation that you have checked the same game.
- Once you find the percentage, write it down before you play. That number applies to this exact build of the game, so you can compare it if you switch casinos, come back to the same title later, or check whether a different version is running elsewhere.
Hit frequency is a separate statistic that measures how often any win shows up. Players often confuse it with RTP, even though the two numbers describe different things. For a separate game review, read Aviator's published RTP figure alongside this guide.
How to Compare RTP Numbers Across Slots
Pragmatic Play lists 96.50% RTP on its official Gates of Olympus page. That is a provider-published figure, not confirmation of the version installed at a casino you are considering. When using a provider page or a review as a reference, make a separate note of what the game itself shows. Keep a general comparison separate from your own session results.
- BGaming treats about 96% as the industry standard. It calls the 96–97%+ range favorable, sees 95% as average, and regards anything below 94% as low RTP.
- Instant-win scratch games are typically configured at around 90%. That is lower than the usual video slot range.
- RTP shows how much a slot is built to return over the long run. Volatility describes how often payouts appear and how large they can be when they hit.
- Theoretical RTP is the percentage built into the game's math and confirmed by testing. Experienced RTP is the return one player actually sees over a limited run of spins.
Compare volatility as well as RTP. Consider whether the payout pattern described in the rules suits what you want from a game. For a closer look at how RTP and volatility play out together in one specific game, see the Gates of Olympus RTP breakdown.
What a Higher RTP Number Does Not Guarantee
For online slots with independent spins, each result is decided by a random number generator. It does not keep track of earlier outcomes. A long losing run does not mean a win is due. That remains true after several losses or several wins.
Free demo play will not reveal a real-time return figure. It cannot prove the percentage in a short test, because RTP is a long-term average. Use the demo to learn the reels, the bonus features and how the paytable behaves. Then check the live RTP figure in the info panel before you wager real money, so you know which version of the game you are actually playing.
