While we play games for a spot of fun and relaxation, we have to admit that we also enjoy spinning the reels for that chance at getting a potentially big payout. But which slots, you might ask? Allay your worries, my friend - this guide is about exactly that! We went through the Slingo library of real online money slots to find which of our games have both the highest RTP and biggest maximum wins.
These are games that, according to their creators, can potentially pay out the most over a long period of time - and we’re going to tell you all about them! Then you’re also at the right place, as we’ll point out what you have to look out for when looking for your next favourite slot.
Check out Slingo’s Best Paying Slots of 2025
So, without further ado, we’re going to introduce you to these slots mentioned above, all available to play here at Slingo this year. What makes these games the best paying? First off, it’s high RTPs that are well over the 96% found in the majority of slots.
The second is big potential prizes that reach well into the thousands of quid. Third, these are slots that are just plain fun, meaning you’ll enjoy playing them no matter the results!
Gold Digger: Mines
First in our list of top payout games at Slingo is Gold Digger: Mines. The first “mines” release from iSoftbet, this is actually not a slot! Instead, Gold Digger: Mines is an instant-win title inspired by the classic Minesweeper. Set your preferred number of mines and, with just one, you’ll get an RTP of 98.88%. Speaking of the wins, these can reach up to no less than £25,000,000, which is more than solid as far as maximum payouts go.
Fruits ChaseNWin
Fruits ChaseNWin is a Spinomenal slot in the classic fruit machine style. This means 3 reels, 3 rows, and 5 paylines. However, it does have a twist - the Chase scatters, which can not only award you with free spins, but are key to this game’s biggest wins. As a result the game has a generous RTP of 98.88%, not to mention a maximum win that can reach up to £25,000,000 through the multipliers unlocked during the free spins feature.
Neon Fever
A stylised classic-style game from Synot, Neon Fever brings 5 reels, 3 rows, and 10 paylines of glowing slot action. Look out for the Double and Triple symbols, which can act as 2 or 3 symbols of that type to further boost any wins you might get. Speaking of wins, these can reach up to £25,000,000 when playing with the game’s maximum bet. Meanwhile the RTP is set at 98.14%, which can potentially allow for decent winnings.
Grand Gems
Enter a world of glowing stones in Grand Gems! This Synot slot features a high RTP of 98.06%, together with prize potential that can reach no less than £4,096,000 when playing with the game’s biggest stake. Land any of the game’s 20 paylines and it will trigger a respin where the winning symbols will stick on the reels. If this leads to more winning symbols or combinations then the process will repeat! Helping you with this are the wilds, which can substitute for all paying symbols and are found on reels 2, 3, and 4.
The Wild Job
The Wild Job is a Synot slot with a Wild West theme set on 5 reels and 3 rows. This setup allows for a total of 9 fixed winning combinations, together with an RTP of 98.05%. Land the 3 scatters found on reels 1, 3, and 5 for a round of free spins. During these the scatter will act as an expanding wild, filling the entire reel whenever landed and substituting for all other paying symbols. This way you can potentially get the maximum win, which can be worth no less than £3,750,000.
Fruity Gold
Synot’s Fruity Gold brings a familiar setup with its 3 reels and 3 rows, but it does have 27 winning combinations - further adding to the excitement! The symbols making these paylines are the classic fruits, but an RTP of 98% and wins that can reach up to £2,500,000 only boost the fun. The reels hold mystery symbols, which can award you with a payout of up to 300x the stake when landed, and double wilds which can double the payout of any winning combinations they make part of.
Lucky Pot
Ready to get your share of the Lucky Pot? This Irish-themed slot from Synot features an RTP of 97.99%, together with 4 reels, 3 rows, and 25 fixed ways to win. The pot itself is, of course, the maximum win, which can total up to £2,500,000! Key to some of the game’s biggest wins are the scatters. Land 3 of these for a mystery win of up to 64x your stake, or 4 for a mystery win that can reach 128x your bet.
How Does RTP Work in Slots?
We’ve been talking about RTP for a while now, but some of you might be asking what this term even means. RTP stands for “Return to Player,” and it refers to the theoretical amount a player can win back from a slot after playing for a long period of time. Let’s say you’re playing a slot with the average RTP of 96%. This means if you’ve wagered £100 on this game over a few hours you should be set to get £96 back, with the remaining £4 going to the online casino.
This sounds easy but there is a big but involved - the RTP is, ultimately, theoretical. Slots are games of luck, and that means you might get a big win on your very first spin or endure a long dry stretch where every spin is a loser. RTP also goes hand in hand with volatility, which is how much frequently a game brings winning spins. As such, it’s important to understand both RTP and volatility if you’re to become a better slot player!
How to Check a Slot Game’s RTP?
Now that you know what the RTP is, how do you check it in the slot you’re playing? This is quite straightforward, and there are three main ways to do it:
- Most online casino sites publish the RTP and volatility information right on the game page.
- The game’s Paytable or About section usually includes the RTP and volatility.
- Failing the above check slot reviews and blogs such as ours!
It’s worth knowing the RTP and volatility information of the games you’re playing if you’re thinking of getting serious about your bankroll management, and it’s just smart practice overall. As a rule slots have a button marked with either “Paytable” or a “?” that will not only let you check the value of the symbols they involve, but also the RTP and volatility.
Weighing the Pros and Cons of High RTP Slots
High RTP slots might sound great on paper, but alas they’re not perfect. What are the issues with this kind of game, you might ask? That’s why we’re listing both the pros and cons of these slots so you can make your informed decision regarding what to play next:
High RTP Slot Pros
- The payouts can get potentially larger through highly volatile gameplay.
- Many high RTP slots add to the excitement with novel bonus features.
- If the high RTP slot has a progressive jackpot then the win potential can only get even bigger.
Low RTP Slot Cons
- You might end up depleting your bankroll faster if you don’t manage it carefully.
- You can only get the biggest wins by placing the biggest bets as you play.
- Slots are ultimately based on luck, so while the RTP might be high you can still end up with regular dry streaks.
Can RTP in Slot Games Vary Over Time?
Some people wonder whether the RTP of a slot varies over time as they play - maybe it gets higher or, even worse, lower? The answer to this question is a firm no. In digital games the RTP is set at a specific value after long periods of testing, and in turn this is audited by third party agencies. This process ensures the fairness of the slot, and is necessary for the game’s developer if they want to be licenced to operate in the UK by the UK Gambling Commission (UKGC).
So, again, remember that the RTP is simply a theoretical value that has been worked out after an amount of spins that is far greater than the average play session. Luck is always a factor when playing slots, and there will be times when you either manage to get good winnings and others when you’ll be left hanging high and dry. So don’t worry too much about the RTP while playing slots and focus on having fun and managing your bankroll to ensure you maximise your time spinning!
Have Fun and Play Smart with the Best Payout Slots at Slingo!
High payout potential can make a slot even more attractive, but do keep in mind that this is just one element that makes for a great game. Slots should make a relaxing pastime, not something to earn money with! This is why the RTP makes for key information since it lets you know the risks a slot involves as you place your bets and spin the reels.
In conclusion, we will always recommend that you play responsibly. Set yourself a bankroll, and manage it carefully by always sticking to it. While you’re at it, never chase your losses. Slots are games of chance, and there’s nothing you can do to affect the final results. Still, we wish you the best of luck while playing at Slingo and, as always, have fun!
