It goes without saying the best payout UK online slots have the biggest maximum wins. We’re trawled the slots world to find you the best payout slots in different categories, giving you a direct line to the most exciting online slots from the last few years.

Since 2019, slot providers have released games with wins of over 100,000 powered by thousands of paylines, supercharged Free Spins bonuses and the biggest multipliers.

We’ll show you the best payout slots from the likes of Netent, Pragmatic Play and Big Time Gaming, and we’ll namecheck the games with the best RTPs too, just for good measure.

What are the best payout slots?

Which online slots payout the most? There are a few answers to that question. You might have come here to see which slots have the biggest multipliers, or find out which slots paid out the most money recently. Or you might want to know which slots pay back the most in general. Chances are, it’s the first one. But just to be sure, we’re gonna cover all of them!

Best payout slots by maximum win

How much can I win with one spin? When you’re learning how to play online slots, the max win isn’t everything. But for some players, that’s the big draw when they’re choosing games to play. Naturally, the slots with the biggest prizes up for grabs will all be progressive jackpot slots. But because jackpot sums change all the time and jackpot slots are in the minority, we’re going to focus on the max wins in non-jackpot slots.

Every slot has a maximum possible win (in coins) and it can vary hugely from game to game. The top win on any single spin of Thor’s Lightning is 1,800 coins – that’s 1,800 times your line bet or 1,800x, as they say most often in the slots world.

How you win that top payout will also vary from game to game. It usually involves the unlikely possibility of landing the highest paying symbol in all positions, perhaps even on all consecutive spins of a Free Spins feature. Pretty unlikely then!

So which of the best payout UK online slots have the biggest max wins? Although there are tens of thousands of slots out there and new games being released every week, this lot is definitely in the running.

1: Wild Cauldron – 211,995x

Wild Cauldron

Released in 2020, this grid game from Quickspin apparently involves tumbles, not spins. You start off with 6 reels, 4 rows and 4,096 Ways or paylines, and each win adds another row. You can get up to 8 rows and a whopping 262,144 Ways.

That epic number of paylines plus Wild Cauldron’s Free Spins and Locking Symbol features can very occasionally combine to produce a win of over 221,000 times your bet. That may well be the biggest non-jackpot payout in the slots world, and with a healthy 96.06% RTP too, Wild Cauldron is arguably kink of the best payout slots.

2: Peking Luck – 180,000x

Peking Luck

Everything gets the multiplier treatment in this Asian themed slot from Pragmatic Play. With a 180,000x max win, it’s no surprise that Peking Luck is a high variance game which scores 5 out of 5 in Pragmatic’s volatility meter.

The Free Spins game has 2 twists; You get a random number of spins and you get a random multiplier too, sometimes as big as 18x. There’s no limit to how many times you can retrigger 10 Free Spins, and when you win using a Wild, you’ll get a nice little 2x bump.

3: Wild Flower – 114,100x

Wild Flower

So fresh you can almost smell the paint, Wild Flower is a 6-reel slot with 4,096 Ways, which partly explains how it has a 114,100x max win. But this release from April 2021 also has Big Time Gaming’s new innovation, Megascatter Enhanced Free Spins.

Spin 3 scatters including a red Megascatter and you’ll get a choice of 2 Free Spins bonuses. Pick the Heart Beats Faster Free Spins and you could get a multiplier of up to 800x on any wins.

4: Dead or Alive 2 – 111,111x

Dead or Alive 2

You wouldn’t think a 5-reel, 3-row slot with 9 paylines could generate a 111,111x payout, but this one’s packed with bonuses that must pack a punch.

There are 3 Free Spins bonuses including one version with 16x multipliers, and this NetEnt western comes with a decent 96.80% RTP.

5: Rome The Golden Age – 100,000x

Rome The Golden Age

NetEnt are at it again with another slot for 2022, this time set in ancient Rome. This 20-line slot is all about the massive Free Spins bonus, which features a progressive multiplier that can go all the way to 1,000x.

Rome The Golden Age has a 3-4-5-4-3 reel configuration which makes for an interesting ride and has a big impact on how you win. But the standout factor that makes this a Best Payout Online Slot is the unusual structure of the bonus features. It’s impossible to explain in 1 sentence, so just try it for free!

6: Buffalo King – 93,750x

Buffalo King

There’s obviously something about 4,096 paylines that can deliver the biggest wins. This one’s from Pragmatic Play and they’ve turbocharged a familiar bonus feature.

Land 3 Bonus symbols to trigger 8 Free Spins. Nothing special there. But land 6 Bonus symbols and you get 100 Free Spins! If that wasn’t enough, there are Wild multipliers of up to 5x during Free Spins, and you can even retrigger up to 100 extra Free Spins. Bonkers. That Free Spins x Multiplier combo is a feature that recurs a lot in this list, and it’s like rocket fuel for max wins.

7: Razor Shark – 85,475x

Razor Shark

Razor Shark is a 20-liner from Push Gaming that stars a classic slot machine feature from yesteryear – the nudge! The reels are packed with Mystery Stacks which also play a big part in the game’s 5 star volatility rating.

Look out for Nudging Free Spins with a progressive, unlimited Multiplier, plus a Razor Reveal feature with multipliers of up to 2,500x.

8: Skeleton Key – 83,333x

Skeleton Key

Good to see old stager IGT joining the party with Skeleton Key, a popular 243 Ways slot from 2020. Like Wild Cauldron, you can expand the reels by spinning key symbols, for up to 7,776 Ways.

You can bag 10 Free Spins with 3 scatters, but any extra scatter adds another Free Spins, so you can bag a load. You can retrigger up to 30 Free Spins too. There’s a progressive or ‘accumulating’ multiplier here too, that ticks up when you hit key symbols. No wonder you can win over 80,000 times your line bet.

9: Toro Rockets – 81,800x

Toro Rockets

Games developer Lightning Box are always one to watch and this 243 Ways slot is a great example of why.

Spin 3 Bonus symbols to unlock the Rocket Collection Bonus featuring 7 Free Spins and a 2x multiplier for any wins using Wilds. Collect enough rockets and you’ll enter stage 2, 3 or 4 of the feature, where any wins using the Wild symbol award a multiplier of up to 25x!

10: Mega Fortune – 80,000x

Mega Fortune

This game, the third of our Netent slots on this list, achieves megastar-level fame because if its standalone progressive jackpot which often exceeds £2 million. But it has a pretty handy maximum win from the base game, too.

It’s also the oldest slot on this list having been released by NetEnt in 2009, a time when a max win of 80,000 was rare. There are various ways to net a big win, starting with 5 Wild symbols worth 10,000 coins on one of its 25 win lines. It is apparently a low variance game but with a jackpot of over £2.8m at the time we wrote this, plus 80,000 max multiplier, we have no idea how!

Best payout slots

Which games pay out the most in real terms? This way of measuring best paying online slots is slightly different. Excluding any crazy jackpot wins, the games that regularly pay out the most are usually the ones that had the most money bet on them in the first place. So this list is useful for seeing which games are the most popular. It’s basically the Top 10 Music Chart for slots.

Here are the best payout online slots at PlayOJO. These 10 famous games were among the highest paying and most popular slots every month at PlayOJO since the turn of the year. And what a collection; Classics like Rainbow Riches, Bonanza and Starburst joined by the new wave of online slots such as 2020 hit Gonzo’s Quest Megaways.

  1. Book of Dead
  2. Wolf Gold
  3. Starburst
  4. Fishin’ Frenzy
  5. Fluffy Favourites
  6. Rainbow Riches
  7. Gonzo’s Quest
  8. Eye of Horus
  9. Bonanza
  10. Mustang Gold

Best payout slots per month

If you’re interested in which slots are paying out the most, and being played the most, you can find out the top 10 every month on the PlayOJO Blog. The year started with Book of Dead as the highest paying slot for January, and by the end of February, there was little change at the top, although Reel King Mega snuck into the top 10.

In March 2021, Wolf Gold shot to 1st place after paying out almost £1.7 million, miles clear of Book of Dead in second. The following month it was business as usual when Book of Dead was the best payout slot for April, though the likes of Eye of Horus JKP, Big Bass Bonanza and 9 Pots of Gold awarded enough prize money to appear in the top 10.

Playing safe on the best payout slots

You may have arrived wondering what the best payout slots in the UK are, but by digging into the numbers, we’ve answered the question ‘what are the best slots to play online?’ too!

If you’ve seen something you like and want to give it a shot, just remember that many of the best slots with the biggest prizes are high variance. This means the results are more unpredictable and you could be waiting much longer – and spending more – before you hit a big win.

However exciting the hunt for a big win is, the most important part of playing the best payout online slots is to play safe.
