Monopoly Big Event RTP is the best paying slot

1. Monopoly Big Event by Barcrest RTP: 99.00%

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%!

Mega Joker RTP

2. Mega Joker by NetEnt RTP: 99.00%

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.

Jackpot 6000 RTP

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, it can quickly becomes one of the best paying slot machines you’ll get to play.

 1429 Uncharted Seas RTP

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!

Joker Strike RTP

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 staggeringly high 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!

Blood Suckers RTP

6. Blood Suckers by NetEnt RTP: 98.00%

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.

Rainbow Riches Pick N Mix RTP

7. Rainbow Riches Pick n Mix by Barcrest RTP: 98.00%

Rainbow Riches Pick n Mix is probably the most interactive of all the games in the Rainbow Riches slots series and also probably the best online slot in the collection. 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.


Starmania RTP

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.

one of the best paying slots Kings of Chicago

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 1920’s – sharply dressed gangsters, beautiful and elegant ladies mixed with stern looking businessmen. Kings of Chicago is one of our favourites from a aesthetics perspective. Check it out today!

Rainbow Riches Drops of Gold RTP

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.

Rainbow Riches Home Sweet Home RTP

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 Fortune Favours RTP

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 payout for this slot will be great, but due to the high volatility nature of this slot, wins are sometimes tricky to come by.

Devils Delight RTP

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!

Magicous RTP and best paying slot

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?

Retro Reels Extreme Heat RTP

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!

Simsalabim best payout slot

16. Simsalabim by NetEnt RTP: 97.5%

In position 16 we find Simsalabim, a 25-payline video slot with an RTP of 97.5%. This slot features a magician and truly has a magic feel to it and is very entertaining. Add on top of this the solid RTP percentage and you have a solid online slot game to try out.

The graphics here truly are fantastic, and the magician theme is unique and original. This slot also has a bunch of special features and game mechanics. When 2-5 scatters appear on the reels you can win up to 200x your money.

Hotline high RTP slot

17. Hotline by NetEnt RTP: 97.4%

Find yourself transported back to Miami during the 1980’s in this popular online slot from NetEnt. Hotline is the 17th best paying slot on our list and comes highly recommended by the team here at Labslots.

Although Hotline is several years old now, it still attracts a cult following. The slot has numerous special features making it unpredictable and exciting whilst there are lots of opportunities for big wins!

Jack Hammer 2 Best payout slot

18. Jack Hammer 2 by NetEnt RTP: 97.1%

Jack Hammer 2 is based on an old style comic book character called Jack Hammer. This is a great slot game for comic book fans as you are taken on a narrative as you progress through the slot.

Jack Hammer’s antagonist is the villain Don Crabby. Although this is several years old now, it still attracts a cult following. The slot has numerous special features making it unpredictable and exciting whilst there are lots of opportunities for big wins!

Hot as Hades high RTP

19. Hot as Hades by Microgaming RTP: 97%

As the title might suggest, Hot as Hades is a slot based on ancient Greek gods. Hades, the God of the underworld is featured heavily in this high RTP slot. Other Greek gods featured include Poseidon, Zeus and the Gorgon Medusa.

Microgaming have done a remarkable job here of developing a great looking game that also plays well and of course, pays well to. Hot as Hades is the 19th best payout slot game and you can find it at most slot sites.

20. Dazzle Me by NetEnt RTP: 96.9%

Play High Paying Slots At UK Slot Sites

Here is the larger list of the best UK slot sites offering players a selection of the best paying slot games:

How Do You Find a Slots RTP?

The RTP percentage of a slot or casino game can be found on the rules of the game’s pay table. Often you have to look for it, but many online casinos will provide the information in their review of the slot. Alternatively, you can check out the slot developer’s game page which will list the RTP of the slot.

RTP Information

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 high RTP slots for the best payout percentage.

The RTP of any slot online is usually available either at the developer’s game page, in the pay-table of the slot or in game reviews.

What Features make a Best Payout slot?

High payout slots offer players a great chance of winning money whilst playing slot games. However, there are several ingredients that make can transform an ordinary slot into one of the best paying slot games.

A High RTP Percentage

The RTP is the percentage of money staked that is returned to the player. For example, if a slot has a RTP of 95%, for every £100 you put into the slot, you will see a return of £95. Of course, this is only an average theoretical speaking. Slots are based on chance and luck, so you could see yourself scoop a jackpot after only two spins, alternatively you may never win before you  lose all your money!

Slot Volatility

The volatility of a slot is an important factor to consider as the volatility decides how often a slot will payout. Low volatility slots will reward players with frequent wins but the payouts will be small. High volatility slots will payout infrequently but when they do, they payouts will be large. Medium volatility slots are somewhere in between high variance and low variance slots.

If you are playing a slot with high variance then you should expect to be spinning the reels for a while before you trigger a bonus round. On the other hand, once you do trigger the bonus, your wins are likely to be huge.

Slot Hit Rates

This term refers to how often you can expect to hit a winning combination on an online slot. Some reviews publish this information but many do not. bear in mind that slots with high hit rates often payout small amounts to make up for the number of hits whilst slots with low hit rates usually payout larger sums.

Hit rates are similar to volatility rates, as slots with a high variance often have low hit rates whilst low variance slots will have high hit rates.

Payout Sizes

It is important to ensure that you are playing a slot game with high-paying symbols. Many slots will advertise frequent payouts but if the majority of these payouts are for less than your stake, you will quickly lose your bankroll.

You should choose to play a slot that offers symbols offering a decent payout each time you land a win from them. Alternatively, jackpot slots offer huge payout sizes, sometimes over £1 million. The downside is that they happen extremely infrequently.

How Do I Choose the Best RTP Slot?

To choose the best payout online slots for you, you’ll need to consider several factors.

  • Ensure the RTP is over 96% – Anything lower than 96% means you will be losing more money to the casino on average than you would be if you were playing a high RTP slot.
  • Pick a slot with a free spins bonus round – Free spin rounds are the rounds which allow you to hit the wins. You should not play a slot game that does not have a free spins bonus.
  • Don’t be drawn into a themed slot which are often not value for money – Many themed slots look pretty but they are often some of the worst for payouts.
  • Jackpot slots payout very infrequently – Be weary of jackpot slots if you are looking to profit. You will win huge money if you trigger the jackpot, but depending on the slot you are paying, the frequency here is super rare.
  • Play the slot for free before you play for real money – Most online slot sites allow you to play a slot for free once you register to their casino.

The surest path to finding the best paying slot games is by testing them for free. Most slot sites allow their players to play for free before depositing.

All you have to do is choose a casino, pick a slot and then click the ‘play for free’ option. You must register to the casino before you are able to play for free. This is so the casino can verify your age.
