No strategy changes how a slot pays. Every spin is decided by a random number generator, independently of the spins before it, and the game is set to pay back less than is staked over time. What you can choose is the game's RTP, its volatility, your stake and how long you play, and those decide how fast money goes and how the results arrive.
RTP and volatility at a glance
| Term | What it means | Where to find it |
|---|---|---|
| RTP (return to player) | The share of all stakes a slot pays back over a very large number of spins. 96% RTP means about €96 back for every €100 staked, in the long run. | The game's info or paytable screen at your casino; our slot reviews |
| House edge | 100% minus the RTP: what the game keeps on average. A 96% slot keeps 4%. | Work it out from the RTP |
| Volatility | How the return is spread: many small wins (low) or rare big ones (high) | Our slot reviews; the maximum win in the paytable is a good hint |
| Maximum win | The biggest payout one spin or feature can give, as a multiple of the stake | The paytable or game rules |
RTP: what it tells you and what it doesn't
RTP is an average over millions of spins by all players. One session can end far above or far below it. What RTP does tell you is the cost of playing over time: stake €1 a spin for 1,000 spins and you have wagered €1,000. At 96% RTP you lose about €40 of that on average; at 94% about €60.
The same slot can come in several RTP versions. The studio offers them and the casino picks which one to run, so a game reviewed at 96% may run at a lower setting where you play. Open the info or paytable screen (usually an "i" or a menu button next to the reels) and look for the RTP before you start.
Volatility: how the money comes back
Two slots with the same RTP can play very differently. A low-volatility slot pays small amounts often; a high-volatility slot can go hundreds of spins with little and then pay a lot. The maximum win is the easiest sign of which you are playing. From our own reviews:
| Slot | RTP | Maximum win | What to expect |
|---|---|---|---|
| Magic Eggs | 96.14% | 40× | Small, steady results |
| Big Bad Wolf | 97.34% | 1,225× | Moderate swings |
| Fishin Frenzy | 96.10% | 2,000× | Moderate swings |
| Gonzo's Quest Megaways | 96% | 20,000× | Long quiet spells |
| Iron Bank | 97% | 49,998× | Very volatile |
With a high-volatility slot, the budget that lasts an hour on a low-volatility game can be gone in a few minutes, even at the same RTP. If you play these, use a smaller stake per spin.
What a session costs
The average cost of playing is stake × number of spins × house edge. Spin speed matters: in Great Britain a slot spin must take at least 2.5 seconds, which allows at most 1,440 spins an hour. At 96% RTP, an hour at that pace costs on average:
| Stake per spin | Wagered in 1,440 spins | Average loss at 96% RTP | At 94% RTP |
|---|---|---|---|
| €0.20 | €288 | €11.52 | €17.28 |
| €1 | €1,440 | €57.60 | €86.40 |
| €5 | €7,200 | €288 | €432 |
These are averages; a real hour can lose the whole budget or end in profit. Bonus wagering works the same way, and our bonus guide has a calculator for it.
Rules that change how slots play
- Great Britain: since 31 October 2021 slots must show your net position for the session, spins take at least 2.5 seconds, and autoplay, turbo or slam-stop features and sounds that celebrate a "win" smaller than the stake are banned. Since 9 April 2025 the stake per game cycle is capped at £5, and since 21 May 2025 at £2 for players aged 18 to 24.
- Germany: licensed slots run with five seconds per spin and other limits; see our German licence guide.
Myths that cost money
- "This slot is due to pay." Spins are independent; a long losing run doesn't make the next spin more likely to win.
- "A near miss means the jackpot is close." Two jackpot symbols and a blank pay nothing and tell you nothing about the next spin.
- "Raising the stake after losses wins it back." It raises the cost per spin; the house edge stays the same.

How slots pay: FAQ
Can you beat a slot machine?
No. Results are random and the game keeps a share of all stakes over time. You can only choose how much it costs you, through RTP, stake and time.
Does a higher RTP mean I will win?
No. It means you lose less on average over a long time. A single session at 97% can still lose more than one at 94%.
Where do I find a slot's RTP?
In the game's info or paytable screen at your casino. Check there, because the casino may run a different RTP version from the one in a review.
What is the maximum stake on slots in the UK?
£5 per game cycle, or £2 if you are 18 to 24, at casinos licensed by the Gambling Commission.
