What does RTP stand for?
So, what is RTP? Let’s start with the basics — it stands for Return to Player, and it’s the percentage of total wagered money that a casino game is expected to pay back to players over time.
Let’s put it into context:
If a slot has an RTP of 96%, it means that — theoretically — for every €100 bet, the game will pay out €96 over the long term. The remaining €4 is the casino’s edge.
Important: Return to Player does not guarantee individual results. You could win big in one session or lose more in another. It is a statistical average calculated over millions of spins or hands.
Why Is RTP Important?
Knowing what RTP is matters. It’s important because it can help you make better decisions and play it smart. Of course, the outcomes are still based on pure luck, but games with a higher RTP value will give you better long-term value because it means you lose less money over time. Well, it doesn’t guarantee short-term wins, but over many bets, you will likely keep more of your money than you would in a low RTP game.
Here’s why you should pay attention to it:
Based on our research, the key idea is that every time you replay your money, you’re giving the house another chance to take its cut. Moreover, cashing out at the right moment helps protect your winnings from being chipped away over time.
For example, imagine you start with € 200 and play a low-volatility slot with a 97% RTP, betting in small amounts. After enough spins, your balance might drop to around € 194. If you keep playing with that $194, you’ll eventually have about € 188, and so on. Repeating this process over and over — say, 30 or 40 cycles — your balance could shrink to half or less, even without any major losses in one go.
How Is RTP Calculated?
Now that you understand RTP, let’s talk numbers. RTP is calculated during extensive game testing. Game developers run simulations with millions of rounds to track how much is wagered versus how much is paid out, giving them a reliable statistical average.
For example:
Once verified, these figures are usually reviewed by independent testing labs like eCOGRA, GLI, or iTech Labs. This means these numbers are fair and accurate because they have been officially tested.
Comparison Across Casino Games
As stated before, you should keep in mind that not all RTPs are created equal — it depends on the game you are playing. Let’s compare the most popular game types — slots and table games!

RTP vs. Volatility: Don’t Confuse Them
So, the RTP tells you how much a game pays you back over time, but volatility describes how often and how big the payouts are.

Where to Find RTP Info?
Most reputable casinos show RTP stats in:
The game’s help or info menu
The provider’s official site
If a casino hides RTP information, that’s a red flag. Transparency is key in regulated iGaming environments.
Can RTP Be Changed?
Yes — and no. Some modern slot games offer configurable RTP ranges to operators (e.g., 88%, 94%, 96%). This means one casino might offer the same game with a lower RTP than another.
Always double-check the RTP in the actual game you’re playing, not just on a general provider list.
Final Thoughts: Does RTP Really Matter?
Absolutely — but it’s not the whole picture.
It helps you make better choices, but luck, timing, and gameplay habits all play huge roles in your session outcomes. Think of RTP as your map — it shows the terrain, but you’re still the one behind the wheel.
If you’re playing for entertainment and know the math, RTP becomes a useful tool rather than just a number. Always combine RTP awareness with responsible play. We understand that sometimes it can be confusing, so we encourage you to check out the RTP calculator we made for our dear readers. Scroll down to get easy instructions on how to use the RTP calculator.
According to our research, you may want to cash out regularly. Moreover, if you keep reinvesting your winnings into the same game, the RTP (Return to Player) applies each time, slowly eating away at your balance, even if you’re winning small amounts along the way.
So, now you know why understanding RTP matters and how to use it to your benefit. Good luck!
