Best Payout Slots FAQs
Here’s a sneak-peak at each of these games in descending order, going from the highest to the lowest RTP!
1. Monopoly Big Event (by Barcrest) RTP: 99%
Monopoly is a well-known game and one we all love. But did you know that Barcrest has created their own online slot version of it, which offers a stupendously high RTP of 99%? The catch, though, is that you have to play it on Big Bet mode to qualify for this RTP.
It might be a good idea to play on the normal mode first and get used to the game before you raise your stakes. However, we strongly recommend using this feature as you’ll then be spinning with a house edge of only 1%!
2. Mega Joker (by NetEnt) RTP: 99%
Mega Joker is another classic slot from NetEnt. It presents two screens with spinning symbols and all of these are just as traditional as the ones found in Jackpot 6000. However, the RTP in this particular game is high enough to enter the very top percentage of payouts.
Mega Joker is a super-fun slot to play and is one we highly recommend. The slot is simple enough for beginners to pick-up instantly whilst the high volatility aspect of the game means that when you do win you will win big.
3. Jackpot 6000 (by NetEnt) RTP: 98.8%
Jackpot 6000 from NetEnt is as classic as online slots get. It even features both the top and bottom parts of the classic fruit machine and offers a sweet RTP of 98.8%. The slot’s three reels and rows will show you traditional symbols such as the lemon, the Joker, the cherry and the grapes. So, go down the nostalgic lane for some big wins!
Jackpot 6000 is a high volatility slot so you have to be patient when playing. Don’t expect frequent wins but be certain that when you do win, the reward will be great.
4. 1429 Uncharted Seas (by Thunderkick) RTP: 98.6%
Pirate-themed slot 1429 Uncharted Seas from Thunderkick has a crazy-high RTP of 98.6%. Unlike many of the other high RTP slots, this game doesn’t require any high roller tactics for you to be able to spin with the incredibly high RTP. This happens automatically, no matter what your bet size is!
1429 Uncharted Seas is a low volatility slot so if you are looking for a game that offers lots of wins then this is the one for you. This slot is also fantastic for beginners who want to experience the feeling of lots of small wins mixed with the odd big win!
5. Joker Strike (by Quickspin) RTP: 98.11%
Joker Strike is a retro-themed slot with top modern graphics and features. The game allows you to play in Hi-Roller mode, which means you’ll have to bet more. But increasing your wager will also mean that you’ll be spinning with a staggering RTP of 98.11%.
As aforementioned, this game is a calling to all you high-rollers out there. Joker Strike offers huge rewards to those players who are willing to risk big money to win big money. Joker Strike is also the highest RTP in a Quickspin game, ever. Take advantage!
6. Blood Suckers (by NetEnt) RTP: 98%
This vampire-themed slot is one of the most popular NetEnt games available. And one of the reasons could be its massive RTP of 98%. It’s often exempted from wagering rules as the RTP is so high that it’s almost possible for the casino to lose money on this slot!
Blood Suckers really is a slot that has it all. From creepy vampires and dark and heavy music to lots of wins and rewards, there is a reason this game is one of the most widely played out of all slot games in existence. You will not be disappointed with this one. Now make sure you have your stake and garlic cloves handy, it’s time to go vampire hunting.
7. Rainbow Riches Pick n Mix (by Barcrest) RTP: 98%
Rainbow Riches Pick n Mix is probably the most interactive of all the games in the Rainbow Riches slots series. It allows you to choose between one to three bonus features before each spin and only the chosen ones appear during your rounds.
The fewer features you choose, the more likely it is that they’ll trigger. To reach the RTP of 98%, again, you’ll need to use the Big Bet feature. If RTP is important to you and you are NOT a high-roller then we would recommend you to pick another game from this list. However, if your priority is playing a super interactive and fun slot then Rainbow Riches Pick n Mix fits this description perfectly.
8. Starmania (by NextGen) RTP: 97.87%
This slot is probably NextGen’s take on a Starburst-like slot. It features glowing symbols in the form of stars and gemstones, all hanging against a backdrop of space. The RTP of 97.87% is just as alluring as the symbols. And thanks to the slot’s generous wilds and bonus symbols, there’s always a new win waiting around the corner.
If you are looking for a slot that is similar to the famous Starburst slot game but with the added factor of a super high RTP, then look no further than Starmania. This slot is a low to medium volatility slot so win should be frequent.
9. Kings of Chicago (by NetEnt) RTP: 97.8%
This is one of the older games from NetEnt’s large selection of slots. Combining elements of video poker with a slot game, it’s relatively simple to play, featuring cards as symbols. However, pay mechanics are a little different. When it comes to RTP, although old, this slot beats many new games as it offers as much as 97.8%!
This slot reminds us of the USA in the 1920s – sharply dressed gangsters, beautiful and elegant ladies mixed with stern looking businessmen. Kings of Chicago is one of our favourites from a looks perspective. Check it out today!
10. Rainbow Riches Drops of Gold (by Barcrest) RTP: 97.75%
Rainbow Riches Drops of Gold from Barcrest works in an identical way to Home Sweet Home (see below) when it comes to RTP. You need to use the Big Bet feature, which gives you a few pre-determined bet sizes to choose from, to be able to spin with a high RTP of 97.75%.
Once again, we would recommend this slot for the high-rollers only given that you need to use the Big Bet feature in order to access the RTP of 97.75%. Alternatively, you can always play this game for free to ensure you are ready to step up as a high-roller.
11. Rainbow Riches Home Sweet Home (by Barcrest) RTP: 97.75%
We have another Rainbow Riches slot on the list, proving that Barcrest is definitely good at offering slots with high RTPs. However, sometimes, like in this case, you’ll need to bet big to reach the high RTP value.
Again, in Rainbow Riches Home Sweet Home you can either bet normally or improve your RTP with the Big Bet feature. Either way, you’ll get to see the Leprechaun knocking on doors above the reels, which will turn certain symbols wild.
Rainbow Riches games are always crowd pleasers and will always come recommended.
12. Rainbow Riches Fortune Favours (by Barcrest) RTP: 97.7%
Completing Barcrest’s bevvy of high RTP slots on this list is Rainbow Riches Fortune Favours, which has an RTP of 97.7%. Just like every other Rainbow Riches slot, this game contains a Big Bet option, and it’s thanks to this special feature that you can increase the RTP to such high levels. Should you opt for a regular bet, the RTP will decrease quite a lot.
If you are not a high-roller you should only use the Big Bet option if you are willing to risk a large percentage of your bankroll. of course, if you win the rewards will be great, but due to the high volatility nature of this slot, wins are sometimes tricky to come by.
13. Devil’s Delight (by NetEnt) RTP: 97.6%
In this slot game, devils and demons spin around on the reels and are surrounded by pentagrams, tombstones, skeletons and even a grim reaper. It’s not NetEnt’s most modern game, but it still holds up quite well against the competition. The RTP of the slot is exactly the same as it is for Magicious below.
The graphics on this slot are fun and the theme is certainly unique. Devil’s Delight is not one for the faint of heart but you should certainly try it out if you are looking for a new kind of slot to play!
14. Magicious (by Thunderkick) RTP: 97.6%
Magicious is a slot from Thunderkick with a truly unique style of animated circus performers and magicians. With an RTP of 97.6%, some pretty decent returns await on this magical slot game. In Magicious, you can hope to land symbols either from the right or the left, as this game pays out from both sides.
Magicious is a low volatility slot so it offers you plenty of wins if you decide to opt into playing this slot. The graphics are fantastic, the theme is magical and the payouts are plenty – what more do you need?
15. Retro Reels Extreme Heat (by Microgaming) RTP: 97.5%
At position 15 is Retro Reels Extreme Heat from Microgaming. This game offers an RTP of 97.5%, which means that for every £1,000 you bet, you can expect to get around £975 back. Just like the name suggests, this is a flaming hot slot with a retro style and traditional layout.
Although this game comes 15th in our list, it is still a slot with one of the lowest RTPs out there. Remember, there are thousands upon thousands of online slot games. Retro Reels Extreme Heat will offer you hours of colourful fun, so sign up and play today!

What is RTP?
RTP stands for ‘Return-to-Player’ and is essentially a way to describe the house edge in a slot. If a slot has an RTP of 95%, it means that the house edge is 5%. The value of the RTP tells you how much you can expect to win (or lose) when playing for a long time. This is why you should always choose a game with a high RTP for the best online slots payout percentage.
The RTP of any slot online is usually available either at the developer’s game page, in the paytable of the slot or in game reviews. The volatility of a slot is usually a little harder to find as developers aren’t actually required to declare that information. However, most reviews will include volatility, also called variance, figure as well.
How Does Slot Variance Work?
Variance describes how often you can expect to win and how likely it is that these wins will be big. So, in a high-variance slot, risks are higher and in slots with a low variance (or volatility), the opposite is true.
Low Variance Slots
When the volatility of a slot is low, you can expect to win more often. However, the wins paid out in low variance slots are usually smaller than in higher-risk games. As a result, you’ll need to put out less money before getting a win, and the risk of running out of funds before actually managing to trigger that payout is small. Still, you probably won’t get a life-changing win.
Here are some examples of the best low variance slots:
- 1429 Uncharted Seas
- Blood Suckers
- Thunderstruck II
Medium Variance Slots
When a slot has medium volatility, you can be sure that it’s a game suited for most players. Medium variance slots pay out less frequently than the lower-risk games, but more often than the higher variance slots. The wins can be either really small or very big, which means that the anticipation for the next spin usually stays high as you never know what’s going to happen!
Some of the best medium variance slots are:
- Rainbow Riches Pick n Mix
- Monopoly Big Bet
High Variance Slots
These are high-risk, high-reward slots. Any win paid out has a higher probability of being bigger than in a low or medium variance game. The downside is, of course, that you might have to spin for quite a while between payouts. Jackpots are great examples of high variance slots.
Here are some of the best high variance slots:
- Book of Dead
- Dead or Alive
- Raging Rhino
Why Do Jackpot Slots Have Lower RTP?
You might have noticed that jackpot slots often have a lower RTP than regular games. This is generally the case with progressive jackpots. The reason is simple: since the slot takes a small percentage of every bet to fill the jackpot, the percentage of your bets paid back to you has to get smaller.
So, as online slots with the best payout go, progressive slots aren’t the greatest, unless of course you’re lucky enough to bag the jackpot!
How Do I Choose the Best Slot?
To choose the best payout online slots for you, you’ll need to consider several factors. First, you should always check the RTP. Don’t go for a game with 95% or lower, unless it’s a jackpot slot. If the RTP of a regular slot is lower than 95%, it just gives the casino an unnecessary advantage. Second, look up the volatility of the game to find out whether the slot you’re considering is high, medium or low risk.
The very last thing to consider is the theme and bonus features. Since there are plenty of games with just the right volatility and RTP out there for you to try, it shouldn’t be too much of a problem to find one that fits you just right!

Thanks for the tips.
I just won a nice amount playing Rainbow Riches Pick n Mix (no jynx). Blood Suckers is a cool game too that I have managed to cash in on.
The Monopoly slot is a dream come true for high slot payouts. Thanks for this!
If you are reading this the Monopoly is the best value for money. I have played every single one of the 15 games in this article and the Monopoly slot is the one I have actually won money by playing.
I am a big big fan of Bloodsuckers slot by Netent, they make good slots and their graphics are amazing. Definitely my No1 game.
I am not a fan of the rainbow riches series at all. I prefer netent slots and my favourite high RTP one is Bloodsuckers 1.
