#1 🥇Ugga Bugga – Playtech – RTP: 99.07%

Ugga Bugga Slot Playtech

  • 📈 Volatility: Low
  • ⚙️ Layout: 3×1
  • 💱 Paylines: 10
  • 💰 Jackpots: ❌
  • 💵 Max Win: $5,000,000
  • 🃏 Bonus Features & Symbols: Hold feature, Respin, Scatters, Expandable Wilds

Ugga Bugga is not your typical online slot – it’s known as the highest payout online slot in the industry. Besides being one of the slots with highest RTP value, it has unique reel mechanics. The paylines are fixed at 10, but you can adjust your bet per spin.

Released by industry giant Playtech in 2006, it’s a low-variance affair with 10 reels. It has a hold reel option like video poker games do and a respin feature borrowed from top online slots. The symbols belong to 4 categories: food bowls, huts, drums, and masks. The highest paying symbol is the Black Mask, bringing 125x your bet.

While this isn’t one of the casino slots that have progressive jackpot networks behind them or Megaways mechanics, the maximum win is $5,000,000, which is more than high! That is if you win on all 10 lines and if you’ve placed a maximum bet of $50 on each line. And once again, for the ones in the back – the RTP of this tiki-themed slot is a massive 99.07%, putting it on the throne of the highest paying slot machines.

#2 🥈Book of 99 – Relax Gaming – RTP: 99.0%

Book of 99 Slot Relax Gaming

  • 📈 Volatility: High
  • ⚙️ Layout: 5×3
  • 💱 Paylines: 10
  • 💰 Jackpots: ❌
  • 💵 Max Win: 12,075x your bet
  • 🃏 Bonus Features & Symbols: Expanding symbols, Wild Book Symbol, 10 free spins, Wild collection

Book of 99 by Relax Gaming is the latest slot with a sky-high RTP to hit the market. Released in early 2021, it’s a cartoon-themed slot game that pays homage to ancient Greece. A bit surprisingly, it’s a volatile title, unlike the others on this list. However, the fact that the stakes are higher also means that you have a shot at higher cash rewards.

The 10-payline slot can deliver wins of 12,075x your bet if you hit the right symbols. With bets ranging from $0.1 to $100 per spin, you stand a chance to get sky-high rewards in the bonus round. The main bonus round uses the popular “Book” style expanding symbols made famous by Book of Ra Deluxe (Novomatic) and the Book of Dead slot from Play’n GO.

This is the perfect high RTP casino slot to clear the bonus wagering requirement, as the RTP is set at 99%, a whole 3% over the industry average.

#3 🥉Mega Joker – NetEnt – RTP: 99%

Mega Joker Slot NetEnt

  • 📈 Volatility: High
  • ⚙️ Layout: 2×3
  • 💱 Paylines: 5
  • 💰 Jackpots: Progressive jackpot ✅
  • 💵 Max Win: 2,000x your bet
  • 🃏 Bonus Features & Symbols: Progressive jackpot, Supermeter reels

With an RTP of a clean and exact 99%, Mega Joker is one of the best casino slots ever developed by NetEnt. Unlike Ugga Bugga, this is as vintage a slot as they come. It’s a classic Joker-style slot that’s the favorite of many players and pays up to 2,000x your stake if you’re lucky.

There’s a catch, though. The 99% RTP is for the Supermeter bonus game. Getting to it isn’t easy, but once you do, you’ll get a better return to player percentage than on any other slot.

Even though it isn’t as complex as Ugga Bugga, Mega Joker is far from the simplest Vegas casino game you’ll find. With 3 reels and 5 paylines, this progressive mystery jackpot slot attracts reel lovers like no other. The maximum bet is $2, which is not really suitable for high rollers, but this is one of the very few high RTP slots that also qualify as jackpot slots.

#4🎖Ooh Aah Dracula – Barcrest – RTP: 99.0%

Ooh Aah Dracula Slot Barcrest

  • 📈 Volatility: Medium
  • ⚙️ Layout: 5×3
  • 💱 Paylines: 10
  • 💰 Jackpots: ❌
  • 💵 Max Win: $250,000
  • 🃏 Bonus Features & Symbols: Free Spins, Big Bet feature

Barcrest is a top slot machine developer – it has been so for quite some time. The legendary studio is behind some of the biggest industry classics and top slot machine games. One of them is undoubtedly the Ooh Aah Dracula slot with an RTP of 99% and the Big Bet feature.

The maximum RTP comes into play when you activate the High Roller mode, so make sure not to miss it. In the base game, the RTP goes up to 96%, which is still decent for a 10-pay lines slot with medium volatility, but the big bet mode and gamble features are where this slot truly shines. The tongue-in-cheek vampire design and funny horror elements make Ooh Aah Dracula a truly unique slot.

Released in 2014, you bet a minimum of $0.1 or a maximum of $500 per spin, which makes this high payout slot a fit for players on a limited budget and for high rollers. You won’t be able to configure the paylines, but if luck is on your side and you’re a high roller, you can get a maximum win of up to $250,000.

#5 🏅Jackpot 6000 – NetEnt – RTP: 98.90%

Jackpot 6000 slot NetEnt

  • 📈 Volatility: Medium
  • ⚙️ Layout: 3×3
  • 💱 Paylines: 5
  • 💰 Jackpots: ❌
  • 💵 Max Win: 6,000x your stake
  • 🃏 Bonus Features & Symbols: Supermeter bonus, Heads or Tails bonus rounds, multipliers

Yet another joker-style slot game by NetEnt, Jackpot 6000 is another vintage slot machine with a sky-high RTP. The payout percentage stands at 98.9%, which is rather close to Ugga Bugga. Play at the max coins to get to the Supermeter bonus, and you’ll get fantastic payouts, which is why Jackpot 6000 is one of the top 10 slot machines on this list and many others.

Make sure you read through the paytable and instructions before playing, as this classic slot requires some optimal strategy to reap the best returns. This is a 3D slot with a fruity theme, 6 betting levels, and 4 coin values.

#6 1429 Uncharted Seas – Thunderkick – RTP: 98.60%

1429 Uncharted Seas slot Thunderkick

  • 📈 Volatility: Low
  • ⚙️ Layout: 5×3
  • 💱 Paylines: 25
  • 💰 Jackpots: ❌
  • 💵 Max Win: 670x your bet
  • 🃏 Bonus Features & Symbols: 50 free spins, wild, scatters

Thunderkick may not be known as the king of online slots with high RTP, but 1429 Uncharted Seas definitely falls into that category. It’s a slot with an RTP of 98.60% that puts you on a voyage through uncharted seas in the Age of Discovery. It’s quite a unique weel-weel-themed slot taking place in an almost live treasure map, with great graphics and animations that stand out from the crowd.

In terms of gameplay, it’s a low-volatility slot game with 25 fixed paylines. The maximum possible win is 670 times your stake, which is more than solid for a slot with such a high RTP. Considering the maximum bet is $100 per spin, you can win a substantial amount of cash with a bit of luck.

Given the low volatility and the high RTP, this makes a perfect machine for completing bonus wagering requirements on!

#7 The Catfather – Pragmatic Play RTP: 98.1%

The Catfather slot Pragmatic Play

  • 📈 Volatility: Low
  • ⚙️ Layout: 3×5
  • 💱 Paylines: 9
  • 💰 Jackpots: ❌
  • 💵 Max Win: 2,251x
  • 🃏 Bonus Features & Symbols: Wild Night, Free Spins, pays both ways, multipliers

A unique blend of cats and the legendary movie The Godfather, the Catfather is one of the highest payout slot machines in Pragmatic Play’s portfolio. This video slot has an RTP that varies between 94.96% and 98.10%. Therefore, this pay-both-ways slot can pay great sums of cash.

Special features include the Wild Night, which is a random expanded wild feature that can cover multiple reels. Get to the free spins round, and that’s where things turn cute and meowy. It’s a purrfect slot that you don’t want to miss if you’re a fan of cats.

With a high RTP, low variance, a minimum bet of $0.09, and a maximum of $45, this game is the perfect video slot for all gambling enthusiasts.

#8 Blood Suckers – NetEnt – RTP: 98.0%

Blood Suckers Slot NetEnt

  • 📈 Volatility: Low
  • ⚙️ Layout: 3×5
  • 💱 Paylines: 1 to 25
  • 💰 Jackpots:
  • 💵 Max Win: $30,000
  • 🃏 Bonus Features & Symbols: Scatter wins, 10 free spins, wild substitute, bonus rounds

One of the premier vampire-themed slots of all time, NetEnt’s Blood Suckers slot is also known for its sky-high RTP, which stands at 98%. A low variance with 25 paylines in play and very regular bonus feature triggers make it an amazing slot choice.

The maximum you can win is up to 900x your stake, which isn’t exactly the biggest winning potential we’ve seen, but it’s more than enough to put it among the best RTP slots in 2023. If you want a touch more variance and volatility in your slot play, then Blood Suckers II, the sequel, offers this along with improved visuals but a slightly lower RTP.

#9 Jokerizer – Yggdrasil Gaming – RTP: 98.0%

Jokerizer Slot Yggdrasil Gaming

  • 📈 Volatility: High
  • ⚙️ Layout: 5×3
  • 💱 Paylines: 10
  • 💰 Jackpots:
  • 💵 Max Win: $6,000
  • 🃏 Bonus Features & Symbols: both way paylines, Mystery Wins

Is there a link between joker-themed slot games and the highest payout slot machines? If you take Jokerizer into question, there surely is. Yggdrasil’s premier 3D slot has an RTP of 98%, but this time, it’s a high instead of a low variance slot game.

The thing that sets it apart is the fun gameplay, which blends old-school action with modern features such as 10 pay both-way paylines. Mystery Wins are a welcome mystery addition that can spice up your wins even further. There’s the same 6000-coin max mystery win, but in Jokerizer mode, it only takes 2 jokers to get a mystery win, which could be a 6000-coin win!

#10 Rainbow Riches – Barcrest – RTP: 98.0%

Rainbow Riches slot Barcrest

  • 📈 Volatility: Medium
  • ⚙️ Layout: 3×5
  • 💱 Paylines: 1-20
  • 💰 Jackpots: ❌
  • 💵 Max Win: $25,0000
  • 🃏 Bonus Features & Symbols: Pick Me bonus round, Pots of Luck feature, Gamble Feature

Yet another vintage Barcrest slot, Rainbow Riches, remains one of the best and most popular RTP slots of all time. It may be over a decade old, but its 98% RTP, medium variance, and 500x wins have stood the test of time.

Due to its overwhelming popularity, numerous versions have been released over the years: Pick n Mix, Megaways, and many other variants. Yet, none of them can beat the original version! You can try it for free to learn the ropes or play it with real money or a no-deposit bonus. Whatever you choose, one thing’s for sure – it’s one of the top highest payout online slots ever.

#11 Starmania – NextGen – RTP: 97.87%

Starmania Slot Nextgen Gaming

  • 📈 Volatility: Low to medium
  • ⚙️ Layout: 3×5
  • 💱 Paylines: 10
  • 💰 Jackpots: ❌
  • 💵 Max Win: 1,000x your stake
  • 🃏 Bonus Features & Symbols: Wild Star bonuses, free games feature, Gamble feature, Wilds, Scatters, Re-spins

NextGen’s sole position on this list is taken by Starmania. The star-studded slot game has an RTP of 97.87% and a low-medium variance. With 10 paylines into the mix and fun gameplay, Starmania is a top slot machine that you don’t want to miss.

Heavily inspired by the more well-known Starburst slot from NetEnt, this machine has very similar base game features but adds a proper bonus round. The base game may not be particularly exciting with wild reels and re-spins, but wait until you get to the free spins bonus round, where the full potential of this slot is to be found.

#12 Zeus Lightning Power Reels – Red Tiger Gaming – RTP: 97.73%

Zeus Lightning Reels Slot Red Tiger Gaming

  • 📈 Volatility: High
  • ⚙️ Layout: 7×6
  • 💱 Paylines: 30
  • 💰 Jackpots: ❌
  • 💵 Max Win: 5,037x your bet
  • 🃏 Bonus Features & Symbols: Expanding Lightning feature, free spins, Zeus wild symbols, scatter

Zeus Lightning Power Reels may not be the slot with the highest RTP on this list, but it surely is among the most exciting ones. Apart from the 97.73% return to player percentage and the high volatility, it also features 30 both-way paylines and Red Tiger’s own Power Reels mechanic.

This special engine pays massive wins if you manage to fill the screen with wilds. Keep a lookout for the large Zeus 1×3 super symbol; this is where the main action comes from. The maximum you can hit is just over 5,000x your bet, which is more than enough to appeal to all slot players.

#13 White Rabbit Megaways – Big Time Gaming – RTP: 97.72%

White Rabbit slot

  • 📈 Volatility: Medium to High
  • ⚙️ Layout: 5 reels
  • 💱 Paylines: 248,832
  • 💰 Jackpots: ✅ Megaways
  • 💵 Max Win: 17,416x your stake
  • 🃏 Bonus Features & Symbols: random bonus features, bonus wilds, multipliers, free spins with expanding reels, Megaways

What is RTP (Return To Player)?

RTP stands short for Return to Player. It’s a term displayed in percentages that shows the likelihood of a slot’s pay rate in the long run based on the money wagered on it. For example, a top slot machine with an RTP of 97% means that it pays back 97% of all bets made back to players, but this figure is worked out over a higher number of wagers (in the millions or even billions while testing the slot for fairness).

To put things into perspective, such a slot will pay you back, on average, $97 on every 100 one-dollar bets per spin. Many players confuse the high slot RTP with a winning guarantee, but they’re not the same. A high-RTP slot may pay more back overall based on the money wagered on it, but winning in online slots is never guaranteed.

For an individual player to win, they need to achieve more than 100% RTP, which essentially means the machine for that specific session paid out more money than what was wagered on it.

Think of the stated RTP on the machine as an indication of how tight or loose it is; the remaining percentage value of 100% is effectively the house edge. The closer to 100% the RTP is, the smaller the casino’s house edge is.

With that being said, all experts recommend playing the highest payout slot machines. They give you a much better chance to win at least some of your bets, which is precisely what all players are hoping for.

Of course, other factors play a role, such as the volatility and variance of a machine, but for what it’s worth, the slot RTP is one of the most important ones. You may also want to read our separate guide on which slot machines have the best odds.

How Is Slot RTP Calculated?

No calculator can tell you the exact slot RTP; the figures displayed on an online slot machine are based on millions of spins where all possible outcomes have been recorded from the machine. In reality, this value should be called theoretical RTP, but players have not adopted this terminology.

You can calculate your own RTP as long as you track how much you have wagered. Simply divide the amount returned from your spins by the total amount you’ve wagered. Let’s put things into perspective:

  • Amount returned: $96.50
  • Total bets: $100 (100 spins at $1)
  • RTP: $96.50/$100 = 96.50%

In most good casino cases, the slot RTP will be displayed clearly in the game instructions, or how can ask customer support to provide this information. However, for slots that don’t list the RTP, be very cautious.

You can start placing $1 bets up to $100 and see what you get in return to calculate the slot RTP, but remember the figures are normally based on millions of spins to avoid errors, so if you are playing a very volatile machine your actual results may vary massively.

How to Tell When A Slot Machine Is About to Hit

Slots is a game of pure chance, so there’s no way to tell when a slot machine is about to hit. They sometimes tend to run hot or cold, just like all random events do. The variance implemented in all slots can result in a string of wins or losses. That’s where the hit frequency and variance come into play, along with the slot RTP.

What’s important to remember is that slots don’t have a programmed predictive value. They aren’t programmed to catch up after big wins and owe you nothing after a string of losses. If anyone tells you they can predict a hot or cold streak on the best casino slots, they’re lying. They can certainly show you one based on previous results, but this has no bearing on the future outcomes of a slot machine.

The RTP percentage value is one of the most important for a slot, so make sure to choose shots with the highest RTP. Secondly, consider the variance and volatility of a machine and pick the ones that match your goals from playing. That goes for both real money play, sweeps casinos, and playing with a no-deposit bonus.
