Which Slot Machines Have the Highest RTP?

Slot machines are exciting and entertaining casino games. What makes them so much fun is that they have all sorts of features, and they come in a wide range of themes. If you’re interested in slot games, you should play high RTP slots with the highest payout rates. This article goes over what RTP is and shows you some slots with the highest RTP percentages.

What Is Slot RTP?

Every online casino game has an RTP, which is a figure that stands for ‘return to player’, and it’s represented as a percentage. It refers to the average amount of money a casino game should pay you in relation to your bet.

If a slot has an RTP of 96%, for example, it keeps roughly 96% of the money spent on it and returns the remaining 4% to players.

Of course, payouts can vary greatly, so when playing an Australian online casino real money 2023 game, you could have lots of losing turns, and a big win could come around. The point of RTP is that it’s an average figure. It’s a long-term average because the figure is calculated by simulating millions of turns.

If you’re trying to make money from online casino slots, you should stick to those with a high RTP. That said, it’s still possible to land a big win when playing a low RTP slot game.

Likewise, you can play high RTP slot machines and still make a loss. You’re more likely to lose less money over long-term play if you stick with slots with high RTP values.

What About Volatility?

Volatility refers to how often a slot pays out and how big the wins usually are. There are three main types of volatility:

  • Low
  • Medium
  • High

If a slot has low volatility, this means that you should win often, though the cash prizes will be on the smaller side. High volatility slots, on the other hand, don’t pay out too often, but when they do, the payouts can be quite large. That is why slot machines are often called machines of chance.

As for medium volatility slot games, these are somewhere in between low and high volatility slots. They can give out generous cash prizes, but they should also give plenty of smaller wins.

The Highest RTP Slots

For most online slot games, the RTP value is around 96%. Some slot games have lower RTPs, and some have higher ones. If you want the best chance of making money from slots, play some of the highest RTP slots listed below.

Ugga Bugga From Playtech – 99.07%

This online slot game from Playtech has perhaps the highest slot RTP ever, though it’s very hard to find; it isn’t available to play at many casinos. Lots of casino sites offer slots by Playtech, but very few of these have Ugga Bugga.

The slot has a tiki theme and ten 3×1 sections where the symbols appear. To win, you have to fill any number of sections with three matching symbols. The features include a wild symbol and a hold and respin feature.

Book of 99 From Relax Gaming – 99%

The theme of this online slot game is ancient Greek mythology. More specifically, the slot focuses on the Trojan War, or rather the aftermath of it.

The main feature of this online slot game is the free spins round, which triggers whenever three book symbols appear anywhere on the slot’s reels. When this happens, you earn 10 free spins, and while using these, one of the slot’s standard symbols is chosen to become the special expanding symbol.

If the special expanding symbol appears, it can expand to fill the reel it’s on. You can win with three or more instances of this symbol, even if they’re not on adjacent reels.

There’s a second way to trigger free spins and this is by collecting wilds. Every wild symbol that lands during the base game is collected in a meter on the left-hand side of the main grid.

Once you’ve collected 99 of these, the free spins round triggers, but there’s a key difference to it. Instead of each spin being worth your current bet, it’s worth the average value of all the bets placed when a wild appeared on the reels. This could be lower or higher than your current bet size, or it could even be the same.

Ooh Aah, Dracula From Barcrest – 99%

Developed by Barcrest, Ooh Aah Dracula is a spooky slot themed to the famous vampire. It has ten paylines and several special features, including a free spins round and a few bonus rounds.

The base RTP is 96%, though this increases to 99% during the hi roller features, which are two optional features you can purchase for an extra cost.

Each hi roller feature starts with free spins and ends with a pick-me game. The cheaper option costs 20.00, and the slightly more expensive one is 30.00. Both options can be worth your while, especially since they have RTPs of 99%.

Mega Joker From NetEnt – 99%

This online slot game from NetEnt came out in 2011 and has been enjoyed by loads of players thanks to its very impressive RTP. When you play Mega Joker, you should get quite a lot of your money back over long-term play. More than most other slots.

Mega Joker is designed to resemble a classic slot machine, though it has something of a jungle theme as there are tufts of grass on either side. The slot’s highly volatile, so while it’s possible to win big, you could go many spins without any wins coming your way.

The slot’s gameplay is stripped back, and there aren’t any bonus rounds. There is, however, a special payout you receive if you happen to land three wilds on the reels. Do this, and you’ll be awarded a mystery win of between 20 and 400 coins; the amount of money that you receive is determined at random.

Jackpot 6000 From NetEnt – 98.8%

Like Ugga Bugga, Jackpot 6000 is designed to look like a classic casino slot machine, though instead of having a jungle setting, it’s placed in a casino. It has three reels and five paylines on which winning combinations can be formed.

You can collect your winnings, gamble them, or play the super meter feature whenever you win. If you decide to gamble, you have to guess the outcome of a coin flip, and if you’re correct, your winnings will be doubled, though if you’re incorrect, you’ll lose your winnings.

As for the Supermeter feature, this is a free spins round where you spin the reels, and whenever two joker wilds appear, you win a mystery prize. This has a value of between 10 and 6,000 coins – hence the slot’s name – and the amount of money that you win is determined at random.

1429 Uncharted Seas From Thunderkick – 98.6%

Created by Thunderkick, 1429 Uncharted Seas is an online slot game with low volatility, a very high RTP and an immersive nautical theme. It’s named after the year that Christopher Columbus landed in the New World in what is now the Bahamas.

The 1429 Uncharted Seas slot game has a wild symbol that lands on reels 2, 3 and 4. Whenever this symbol appears, it expands to fill the reel it’s on, essentially giving you a fully wild reel.

The slot’s main special feature is the free spins round, which comes into play whenever three or more compass symbols land. The number of spins you receive depends on the number of compasses there are.

Should three compasses appear, you’ll receive a total of 10 free spins, and if there are four compasses on the reels, it’s 20 free spins you’ll get. Whenever you spin the reels, and there are exactly five compass symbols on the screen, you’ll be awarded a batch of 50 free spins. The wild expands in the free spins round just like it does in the base game, which can make the free spins round very valuable indeed, though only if you’re lucky. The slot’s gameplay is straightforward, so it should appeal to players who enjoy games with simple, uncomplicated features. It is not that difficult, like the eternal confrontation between IOS or Android when you select the one for yourself.


For your best chance at making money from slot games, stick to top RTP slots. It’s easy to find out what a game’s payout rate is. When you load a slot, check the paytable, and this should display RTP.

If not, the casino might list it alongside general information about the slot. If you still can’t find the RTP, a quick online search should solve the problem.

Before trying slots for real money, you might want to play demo versions of them to see what they’re like without risking your money. Most casinos let you play slots and other games in demo mode once you’ve set up an account.
