We Checked the RTP of 114 Online Slots
We pulled the published RTP of all 114 slots and live games we've reviewed and ran the numbers. The average return was 95.84%, slightly below the 96% baseline the industry likes to quote, with individual games ranging from 88.12% up to 99.59%.
Key takeaways
- Across the 114 games we've reviewed, the average RTP is 95.84%, just below the 96% figure commonly quoted as the slot baseline.
- RTP ranged from 88.12% on Mega Moolah to 99.59% on Cash or Crash, a spread of more than 11 percentage points.
- Only 8 of the 114 games returned 97% or more; the largest group, 42 games, sat between 96.00% and 96.49%.
- Among studios with several titles, Evolution averaged highest at 96.72% and Play'n GO lowest at 94.66%.
- A higher RTP improves long-run returns but says nothing about volatility, so it is not a shortcut to winning.
We wanted a clear answer to a question players ask constantly: what RTP do online slots actually return? So we took the published return-to-player figure for every one of the 114 slots and live games in our review library and ran the numbers. The headline: the average sits at 95.84%, a little under the 96% the industry treats as standard, and the gap between the best and worst game is wider than most players expect.
What we found
The mean RTP across all 114 games was 95.84%, with a median of 96.06%. The full range ran from 88.12% at the bottom to 99.59% at the top, a spread of over 11 percentage points. In plain terms, the worst-returning game in the set keeps almost twelve cents of every dollar staked over the long run, while the best keeps less than half a cent. That spread is the single most useful thing to take away: the label “slot” covers games with very different long-run economics.
The full RTP distribution
Most games clustered in a narrow band just under and just over 96%, with a thin tail of high-RTP titles above 97%.
The biggest single group, 42 of the 114 games, returned between 96.00% and 96.49%. Another 29 sat in the 95% band, and 18 came in below 95%. At the top, just 8 games returned 97% or more. So while 96% is a fair rule of thumb, more than two in five games we reviewed actually returned less than that.
The highest and lowest RTP games
The top of the table is led by live and table-style formats, which tend to carry higher returns than reel slots:
- Cash or Crash (Evolution): 99.59%
- Blood Suckers (NetEnt): 98%
- Sugar Rush 1000 (Pragmatic Play): 97.5%
- Lightning Roulette and XXXtreme Lightning Roulette (Evolution): 97.3%
At the other end, the lowest returns came from a mix of high-volatility slots and one famous progressive jackpot:
- Mega Moolah (Microgaming): 88.12%
- Pirots (ELK Studios): 94%
- Das xBoot (Nolimit City): 94.02%
- Twin Spin (NetEnt): 94.04%
- Deadwood (Nolimit City): 94.15%
Mega Moolah is the clear outlier, and there is a reason. Progressive jackpot slots skim a slice of every bet to fund the headline prize, which pulls the base return down sharply. Its 88.12% is the price of a shot at a life-changing jackpot, and it is worth knowing before you spin.
RTP by studio
Returns also varied by the studio behind the game. Among developers with several titles in our set, the averages ran like this:
| Studio | Games | Average RTP |
|---|---|---|
| Evolution | 9 | 96.72% |
| Big Time Gaming | 6 | 96.40% |
| Relax Gaming | 6 | 96.25% |
| NetEnt | 7 | 96.08% |
| Pragmatic Play | 32 | 95.97% |
| Hacksaw Gaming | 15 | 95.78% |
| Nolimit City | 11 | 95.69% |
| Play’n GO | 8 | 94.66% |
Evolution sits highest, helped by its live and game-show titles. Play’n GO sits lowest in our sample, and that points to a wider trap: several studios, Play’n GO among them, ship the same slot in more than one RTP version, often a high one and a noticeably lower one. The casino chooses which to run, so the figure you actually play can sit below the maximum the game supports. Always check the RTP shown in the game itself.
What the numbers mean for players
The practical takeaways are simple. Treat 96% as a baseline rather than a promise, since our average came in just under it and a large share of games returned less. Bear in mind that a higher RTP improves your long-run return but tells you nothing about the ride, which volatility describes: a 96.5% slot with very high volatility can still empty a balance in a short session. And watch the format, because live and table games often return more than reel slots, while progressive jackpots return the least, since they are funding a prize.
You can compare every game in this study yourself in our RTP comparator, sort it by return or volatility, and dig into individual titles through our slot reviews and the studios behind them on our providers pages. RTP is one of the few hard numbers a player can check before staking a cent, so it is worth the look.

Frequently asked questions
What is the average RTP for slots?
Across the 114 games we reviewed, the average RTP is 95.84%. The widely quoted industry baseline is 96%, so our sample came in just under it. Averages shift by studio and game type, and individual titles range widely, so treat 96% as a rough benchmark rather than a fixed rule. Our comparator sorts every game by RTP so you can see exactly where one falls.
Is 96% RTP good?
Yes, 96% is solid and sits right around the industry baseline. In our data it is slightly above the 95.84% average, so a 96% slot is a touch better than typical. Anything above 96.5% is genuinely player-friendly and fairly rare, while below 95% is on the stingy side. Remember that RTP is a long-run average measured over millions of spins, not a guarantee for one session.
What slot has the highest RTP?
Among the games we reviewed, Cash or Crash leads at 99.59%, though it is a live game-show rather than a reel slot. The highest pure slot is Blood Suckers at 98%, followed by Sugar Rush 1000 at 97.5%. Live and table formats often edge above reel slots on return. Sort the comparator by RTP for the full order from highest to lowest.
What slot has a 99% RTP?
Very few games reach 99% RTP. In our sample only Cash or Crash, a live game-show, clears it at 99.59%. Reel slots rarely go that high, and the best ones we reviewed top out around 98%. A 99% return means roughly a 1% house edge, which is unusual for slots and closer to what some table games offer.
How to find slot machines with higher RTP?
Check each game's published RTP before you play, usually shown in the game's info panel, and compare it against the 96% baseline. Our comparator does this across all 114 games at once, sorted highest to lowest. One catch: some studios release the same slot in several RTP versions, so the figure a given casino uses can be lower than the maximum the game supports.
What slot machine is most likely to pay out?
There is no machine that is due to pay, since each spin is independent. What you can control is the long-run return and the swing. A higher RTP returns more over time, while volatility describes how often and how big the wins land. A low-volatility slot pays smaller amounts more often; a high-volatility one pays rarely but larger. Read RTP and volatility together rather than chasing either alone.
