Highest RTP casino-style slots ranked
There are thousands of vegas-style slot games currently on the market for players to try, so much so that it can often be very confusing in terms of which one to pick. Furthermore, the RTP rates are not always made readily available, at certain social casinos this information can be difficult to find. That’s why I’ve decided to compile a list of some of the highest RTP online slots for you to try out at your favorite sweepstakes casino, so if you’ve been on the hunt for the best RTP slots then sit back as we provide you with a comprehensive list.
If you’re wondering what is considered high RTP, it’s anything above 97%. The 94 – 96% category is where a lot of slots fall under, and anything below 94% is not recommended as it’s considered a low RTP value.
In the table below you’ll find a list of the highest RTP slots to play:
| Slot Game | RTP | Developer |
| 1. Ugga Bugga | 99.07% | Playtech |
| 2. Mega Joker | 99% | NetEnt |
| 3. Book of 99 | 99% | Relax Gaming |
| 4. 1429 Uncharted Seas | 98.6% | Thunderkick |
| 5. Marching Legions | 98.12% | Relax Gaming |
| 6. The Catfather | 98.10% | Pragmatic Play |
| 7. Blood Suckers | 98% | NetEnt |
| 8. Money Cart | 98% | Relax Gaming |
Ugga Bugga – Playtech – 99.07% RTP
Ugga Bugga Slot
Ugga Bugga is the highest RTP slot on this list, coming in at first place. This slot game was developed by Playtech who are pioneers in the gaming industry and for good reason. With such high return rates you’ll be able to spend many hours of fun on this excellent game. This game features 10 reels and 10 paylines, with the potential to 1,000x your initial playing amount. However, the slot is generally seen as a low volatility game, meaning you’re more likely to see small returns than large ones.
Mega Joker – NetEnt – 99% RTP
Mega Joker Slot
Mega Joker is another excellent option for those looking to find the highest RTP sweepstakes slots. This NetEnt progressive slot features 5 paylines, 5 reels and a progressive jackpot. I love the theme for this game too, it’s extremely engaging through-out and really helps to bring the reels to life. It’s truly one of the most nostalgic fruit slot machine experiences that you can get out there currently and the high RTP rates are of course a great added bonus.
Book of 99 – Relax Gaming – 99% RTP
Book of 99 Slot
Released in 2022, Book of 99 remains one of the highest RTP slots in the market. This time it’s from the developer Relax Gaming and features a more traditional layout of 5×3. Additionally, the ancient mythology theme to this slot is a fan favorite, helping to bring that little bit of added magic to this slot. Watch out for the Sacred Scripture symbol, as this acts as both the wild and scatter. Three or more book symbols will trigger ten free spins.
1429 Uncharted Seas – Thunderkick – 98.6% RTP
1429 Uncharted Seas Slot
Dropping down from the 99% threshold into an RTP of 98.6% we have 1429 Uncharted Seas. While it might have slightly lower RTP, it still remains one of the highest payout slot machines. Worth a shot in my opinion! It’s produced by the developers over at Thunderkick and features 5 reels and 25 paylines. This sea-themed slot will trigger a round of 10 free spins when 3 scatter symbols land on the reel. This can go up to 50 free spins with the maximum 5 scatters. There’s also the chance for returns 670x your initial playing amount.
Marching Legions – Relax Gaming – 98.12% RTP
Marching Legions Slot
Marching Legions by Relax Gaming is one of the high RTP slot machines that made this list and it has earned its place in my opinion. Of all the games I’ve played and reviewed in my time, Marching Legions is one of my favorites, but maybe because I truly love the whole Roman Empire theme that this slot offers. There’s plenty of excitement when spinning the reels; stacked symbols can trigger respins, build up a meter that can lead to a free spins bonus round. Progressing through it can win up to 10,000x your total bet.
The Catfather – Pragmatic Play – 98.10% RTP
The Catfather Slot
The Catfather is a high RTP slot machine with a wide variety of cool bonus features that make it an exciting play. From generous wilds to free spin rounds and more, you’re always kept on the edge of your seat with excitement when it comes to this awesome slot. An interesting part about the free spins round is that all potential returns are multiplied by 4 during this time, making for prizes of epic proportions. Furthermore, this one is developed by the team over at Pragmatic Play and features a 5×3 layout.
Blood Suckers – NetEnt – 98% RTP
Blood Suckers Slot
When thinking of the highest RTP online slots, one that immediately jumps out to any knowledgeable gamer is Blood Suckers. This game features an RTP of 98%, which is very generous to say the least, the game is played on 5 reels and has an exciting vampire theme to it. Keep an eye out for the hammer and stake as this is the bonus symbol. Three bonus symbols will trigger the bonus round, where the maximum win is 20,320.
Money Cart – Relax Gaming – 98% RTP
Money Cart Slot
Another slot with a whopping 98% RTP is Money Cart and this time it’s developed by Relax Gaming. As
high volatility slots
go, this game is definitely one of them, so I’d recommend it to slot players looking for the chance of big payouts. With 5 reels and 4 rows this slot game is set in the wild wild west, and has plenty of bonuses to look forward to. Land 3 bonus symbols in one spin to trigger 3 re-spins.

- Demolition Squad
– 97.1%
- Jack Hammer
– 97.07%
The Highest RTP Slots by Pragmatic Play
You might have noticed that Pragmatic Play didn’t feature heavily in my list of highest RTP slots. This is because Pragmatic Play isn’t known for very high RTP, with a lot of slots averaging 96-97%. Since Pragmatic Play is hugely popular, I’m listing the best from Pragmatic as anything above 96% is still respectable RTP.
- The Catfather
– 98.10%
- 888 Gold
– 97.52%
- Gold Train
– 97.16%
- Caishen’s Gold
– 97.08%

Pros and Cons of playing the highest RTP Online Slots
There are a lot of amazing reasons to play high RTP slot machines and there’s also a few reasons why you might not want to consider playing them. As with anything it’s always important to weigh up the benefits against the drawbacks. Here are some of the most significant pros and cons for playing the highest RTP online slots:
Advantages
- Greater percentage of virtual currencies redistributed to player
- Typically associated with less volatility
- Can help to extend gaming time
- Great entertainment
- Developed by leading software providers
Disadvantages
- Often lower return potential
- Limited game selection
- RTP is not a guarantee of returns
How is RTP for slot games calculated?
The simplest way that slot developers and casinos use to calculate the RTP of a slot is with the following equation: Return to Player = (Sum of Wins / Sum of Bets) / 100%.
For example, if someone was to theoretically play with 100 Gold Coins and the game returned a total of 95 Gold Coins then this can be seen as an RTP of 95%. Likewise, if the player uses 100,000 Gold Coins and is returned 98,000 Gold Coins then the RTP is assumed to be 98%. Therefore, the higher the RTP the more the player should theoretically expect to see returned to them. However, this is simply a guidance figure and players could see a slightly different return in reality, as slot games are subject to variance and chance.
How is RTP different from volatility?
Another term you’ll encounter very frequently is slot volatility or variance. A lot of players mix this up with RTP, but the two definitions refer to different things.
While RTP refers to the average return you can expect over a period of time, slot volatility is how often a game will pay out. There are three different categories:
- Low volatility slots: A slot will pay out frequently but in small amounts.
- Medium volatility slots:
A slot that is in between low and high. You expect semi frequent payouts that are neither too low nor high.
- High volatility slots:
High volatility slots can have lots of dead spins, but when they hit, they might hit big.
Final thoughts on this high RTP slots guide

However, these benefits come with some drawbacks, including lower return potential, limited game selection, and the fact that RTP is only an estimation, not a guarantee of returns.
