Best RTP Slots

highest RTP slots

For experienced slots players, one of the most important pieces of information about a casino game is its RTP. The Return to Player value can help players to gauge, roughly, how much they can expect to lose when playing a particular title.

Need a refresher? No problem. Think of RTP as a sort of ‘reverse’ House Edge. Let’s take that favourite slot, Starburst, as an example. NetEnt tells us that the RTP for Starburst is 96.1%. If we apply our previous analogy, that means the ‘house edge’ would be 3.9%. Theoretically, that means that players will get back 96.1% of what they wager.

Of course, this doesn’t mean that for every £100 wagered on Starburst a player will necessarily win back £96.10. That’s where that word ‘theoretically’ comes in. If there was such certainty, there’s no real point to gambling at all is there?

[js-featured-quote]RTP is calculated over the long-term, not per wager. [/js-featured-quote]

RTP is calculated over the long-term, not per wager. So a player could walk away with an £80 win on a £10 wager or with a completely empty bankroll. Slot games are completely random, thanks to their RNG technology, but the Return to Player value gives a helpful indication.

So what are high RTP slots? Well, that’s kind of an arbitrary thing and it varies depending on who you ask. At JohnSlots, we think that:

  • A high RTP is anything at or above 98%
  • A mid-range or average RTP is anything that falls between 95% and 97.99%
  • RTP values below 94.99% would be considered low

Highest RTP Slots

As you might imagine, the highest RTP online slots are very attractive to players as they are the ones players are less likely to completely wipe out their bankroll on. Read on to find out which games have the highest return to player and where you can find the best RTP slots to win most of your wagers.

1. Ugga Bugga by Playtech

Ugga Bugga slot from Playtech

RTP: 99.07%

Playtech takes us to the jungle in Ugga Bugga, a slot released in 2006. There are tropical fruits, tribal masks and bongos galore on this unusual slot, which lines up no fewer than 10 rows of 3 reels each, in two groups. Each reel spins independently of the others and there are 10 paylines built in.

Ugga Bugga has low volatility and the Wild symbol is the only real bonus feature to speak of but this game still keeps us coming back for more thanks to its unique layout and high RTP.

2. Rainbow Riches Pick n Mix by Barcrest

Rainbow Riches Pick n Mix

RTP: Up to 98%

This 2016 sequel to Rainbow Riches throws in a number of new bonus features that will appeal to players who enjoy high RTP online slots. As you can see, we’ve listed this one as ‘Up to 98%’ and that’s because of the Big Bet feature.

The Big Bet feature allows players to increase their stake while simultaneously triggering three bonus features, which will then be applied to the subsequent set of free spins. This aside from the coin wins, multipliers and more that Rainbow Riches Pick N Mix has to offer by way of bonuses.

3. Mega Joker by NetEnt

Mega Joker slot from NetEnt

RTP: 99%

With its classic fruit machine style and a progressive jackpot, the Mega Joker slot from NetEnt has been a fan favourite since its release in 2013. Much like the old slot machines, it takes its inspiration from, Mega Joker is fairly simple – 3 reels, 3 rows and 5 paylines.

However, there’s a lot more to this slot than meets the eye. Aside from the high RTP, it also has a progressive jackpot. And if there’s one phrase that is more enticing to players than ‘high RTP’, it’s ‘progressive jackpot’!

4. Ooh Aah Dracula by Barcrest

Ooh Aah Dracula slot by Barcrest

RTP: 99%

We love the catchy title on this Barcrest slot! Ooh Aah Dracula (it’s just so fun to say!) was released in 2015 and features an equally lively soundtrack to match its whacky design.

Built on a 5×3 reel set, this game has 10 betlines, a medium variance, and free spins, Wilds and a pick and click bonus game. There’s also a high-roller option that triggers 5 spins at the given stake. Though perhaps saying the word ‘stake’ around vampires may be a little insensitive.

Jackpot 6000 slot by NetEnt

RTP: 98.86%

With 5 reels, 3 rows and a familiar classic slot appearance, Jackpot 6000 may not appear to be all that exciting. But look closer and you’ll notice not just a high RTP but an in-game jackpot too!

The Supermeter feature is where the fun is at. When a win is struck, players are given the option to use those winnings to play the Supermeter, which costs more but can reward with up to 6,000 coins when two jokers land on the reels to reveal a mystery prize.

RTP: 98%

This high RTP game from Yggdrasil brings classic fruit machines into the modern world, with sharp graphics and exciting features. Jokerizer was released in 2016, so it still looks mighty fresh and its high variance is also appealing.

Built on a standard 5×3 reel set and replete with familiar fruit symbols, Jokerizer changes the game with its Jokerizer Mode and the Mystery Win feature.

9. Blood Suckers by NetEnt

Blood Suckers by NetEnt

RTP: 98%

What is it about vampires? Blood Suckers is the second slot on our list with a vampire theme, though this one is very different to the Barcrest title we talked about earlier.

Blood Suckers was released in 2013, with a sequel launched four years later. The first instalment is all about that creepy Victorian violin music, free spins and a rather macabre pick and click bonus game that only ends when the player has dispatched all of the undead.
