Best new bingo sites selection - Best RTP Slots

All of the slot games on this page have Return To Player of 97% or more, making them some of the best RTP slots available.


  • Play King’s Honour at Videoslots
    11 Wager Free Spins & Deposit £10+, Get 100% bonus up to £200

    King’s Honour is a ten reel slot that features the same Colossal Reels engine found on Rainbow Riches Reels of Gold. As a result, the game includes the same bonus features albeit with a medieval twist. The Big Bet mode is also available.

    The action takes place across two reel sets. The main reels feature a 5×4 layout while the Colossal reels have a 5 x 12 configuration. Low value symbols are represented by playing card icons (brilliant!) while medium to high symbols are signified by goblets, crowns and axes.

    Like Reels of Gold, King’s Honour includes an excellent array of bonus features. Highlights include transferring wilds in which stacked wilds transfer to the Colossal Reels and fully expand.
    Then you’ve got the Kings Charge Bonus mechanic – a random ‘mystery’ bonus where a picture symbol is selected and then repeated across the reels, sometimes covering multiple positions.

    There’s also a Siege Spins feature that awards a single re-spin when you land 2 free spin symbols. Should at least three bonus symbols appear on reels one, three and five, the Reel of Honour is activated and you’ll get the chance to spin for free spins, multipliers and cash prizes.

    As is the case with all Barcrest Big Bet slots, you can also purchase five linked spins for either £20 or £30. With both options, any wild that turns up on the left reel set will expand to fill all positions and transfer to the Colossal reels game area. The same applies for the £30 mode but with the added benefit of bonus symbols which can appear in any position across both game areas.

    RTP: 97.5%, Minimum Stake: 0.10

  • Play Steam Tower at Win British
    Deposit £10+ To Spin The Mega Reel - Top Prize 500 Slot Spins On Chilli Heat

    Steam Tower is a five-reeler from Net Ent that offers a reasonably generous RTP of 97.04%, stacked wilds and a standout free round featuring multipliers of up to x7. Inspired by the Steampunk subgenre this sleek and polished offering from Net Ent has managed to survive the ravages of time, despite being released six years ago.

    Sporting a retro-futuristic theme, the game area is set against a kind of industrial background. The top-hat protagonist stands next to the reels – the goal is to help him climb a tower in order to rescue a princess. This can be achieved in the free spins game.

    To activate the round you’ll need to land one or more stacked wilds. Achieve this and you’ll be rewarded with 10 free spins and the hero will climb to the first floor. To ascend the floors you’ll need to land the same amount of wilds. Each floor contains the following multipliers:

    • Floors One to Three – 2x
    • Floors Four to Six – 3x
    • Floors Seven to Nine – 4x
    • Floors Ten to Twelve – 5x
    • Floors Thirteen to fifteen – 6x
    • Floor Sixteen – 7x

    RTP: 97.04%, Minimum Stake: 0.15

  • Play Fruit Warp at Casushi
    Deposit £10 - £50, Get 100% Slot Bonus & 50 Spins (Book of Dead)

    Fruit Warp is an unusual ‘slot’ game from Thunderkick with no reels or pay-lines to speak of. So instead of matching symbols across pay-lines, the object of the game is land combinations of three or more fruits.

    Although it’s been seven years since the game’s release, Fruit Warp remains highly original. This may be because nobody deemed the concept worth imitating. But no matter – it’s a highly playable slot, albeit without much imagination in the visuals department. A mystical soundtrack accompanies play which happily doesn’t require the mute button.

    Instead of reels, you’ve got floating symbols that comprise bananas, grapes strawberries and origins. Nine of these appear for each spin – match at least three and you’ll win. If you manage 4, the winning symbols remain in position and a re-spin kicks in.

    The game’s standout feature (in addition to a generous RTP of 97%) is the ‘Fruit Mode’ which is activated by landing five symbols. During this round, you’ll receive a spin every time the triggering symbols appear. There’s also an incremental multiplier in play that increases with each sinning spin.

    RTP: 97%, Minimum Stake: 0.10

  • Play 1429 Uncharted Seas at Playzee
    Deposit £20 - £300, Get 100% Slot Bonus, 100 Zee Spins + 500 Zee Points

    1429 Uncharted Seas is a five reel slot from Thunderkick with 25 pay-lines, a potentially generous free spins bonus round and a high RTP of 98.5%. This nautically-themed game was released in 2014 but still manages to hold its own in the visuals department.

    In fact 1429 drifts dangerously into the mysterious waters of design originality – the reels are actually themed around an ocean chart and are replete with items one might associate with the mythical high seas, including an octopus, lobsters and a mermaid. Should five of the latter symbols emerge on a pay-line, you’ll receive 50x your stake.

    A ship serves as the wild, appearing on the second, third and fourth reels. Replacing all other symbols save the scatter, it will expand when part of a winning combo. It’s possible to land three expanding wilds during the base game.

    The bonus round is unlocked by unveiling the scatter symbol (compass) at least three times. You’ll then be rewarded 10, 20 or 50 free spins depending on how many appear. The lofty return to player rate is one of the main USPs here as is the low volatility, which means this well conceived slot is ideal for playing through bonus wagering.

  • Play Wild Orient at Videoslots
    11 Wager Free Spins & Deposit £10+, Get 100% bonus up to £200

    Wild Orient is a Microgaming slot with five pay-lines, 243 pay-lines and a 97.55% RTP. Launched in 2015, it also includes free spin and re-spin features.

    The game sports an Asia jungle theme. Accordingly, the reels are framed in bamboo and set against a dense jungle background. A plunking inoffensive far-eastern ditty plays in the background – sadly this is undone by the vacuum-cleaner sound effect accompanying every spin.

    The reels are populated by an assortment of exotic animals including a monkey, tiger and elephant. Not in keeping with the game’s theme in any way are playing card symbols which represent low value symbols.

    In the base game all wins pay left to right with standard wilds also in play on reels two and four. These substituted all other symbols apart from the scatter.
    After each spin, you get the option to re-spin individual reels at a small extra cost. This can prove useful in forming winning combinations or by landing the third scatter – all wins arising from scatters are multiplied by the total amount you stake.

    If you manage to land at least three, with or without the re-spin feature, you’ll receive 15 free spins and each win is tripled. The free spins can be re-triggered should you manage to uncover another three wilds during the round.

    RTP: 97.5%, Minimum Stake: 0.01

The Best Slot Payouts?

Players at online casino and slot sites are always looking for the best payout slots.  A very important factor in this is Return To Player (RTP) but as we’ll explain later, the best payouts can often come from slots with lower RTP.

Online slot games with high RTP are popular with players for two reasons.

  1. Better long term returns
  2. The best RTP slot games are ideal for clearing wagering requirements

While there are other important metrics that should be considered when choosing a slot game to play, RTP is a pretty good starting point.

What is Slot Game RTP?

RTP (return to player) is a measure of the amount of money that an online slot will pay back over time. It’s an important piece of information, offering a reasonably accurate indicator of what will happen to your bankroll if you keep playing the same game for tens or hundreds of thousands of spins.

RTP rates are expressed as percentages and specify your average winnings per £100 staked. So if you were to play a slot game with a 98.3% RTP, you would on average receive back £98.30 for each £100 of play. This means that the house would hold an edge of 1.7%. Of course, the £98.30 is per £100 of play, not per £100 deposited; if you continue to play with whatever you have left after the first £100 of play, the 98.3% applies to that as well, rather like compound interest.

Given that RTP is based on very long-term projections, what you actually end up with after a few hundred spins may bear very little relation to the RTP figure. Nonetheless, it’s a useful bankroll management tool that can prevent you from haemorrhaging cash on slots with a big house edge. So what’s considered a high RTP slot game?

High RTP Slot Games

The best RTP slots have a return to player of 98% or more, but there aren’t too many of these. Typical examples include Beat the Bank (99.17%), Ugga Bugga (99.07%), Blood Suckers (98%), Mega Joker (99%) and 1429 Uncharted Seas (98.6%).

Medium to High RTP Slot Games

RTP of between 95% and 96% is pretty par for the course for modern online slot machines.

Once you get above 96%, anything up to 98% is considered a mid-to-high RTP slot game. There are plenty of titles that fall into this range such as Jack Hammer 2 (97.1%), Kingdoms Rise Chasm of Fear (97.06%) and Steam Tower (97.04%).

Latest High RTP Slots

Although more than a few high RTP slots have been released in 2021, many have fallen under the radar, both with players and online casinos. There are a few exceptions that can be found at certain operator sites. These include Money Cart 2 (98%), Money Cart Bonus Reels (98%) and Book of 99 (99%). But be advised that most online casinos have seen to it that these games contribute 0% towards wagering – so in all likelihood, they can’t be used to play through welcome bonuses.

Slot Game RTP – Other Things to Consider

When choosing which online slot game to play, there are a few other metrics to consider along with RTP.  Variance is perhaps the most important.

RTP vs Variance

While RTP describes expected returns over the long term, it isn’t a good indicator of potential win size or win frequency. To determine this, seasoned players use a measurement called variance which essentially describes how much difference there is likely to be between the slot’s RTP and what you ACTUALLY win or lose in a session.  Another, somewhat more descriptive, term for variance is volatility; the dictionary definition of the word is “liability to change rapidly and unpredictably” and that’s just what happens with a high volatility slot game.  One minute, you’re winning big and the next, you’re losing your shirt.

Low Variance Slots

Low-variance slots will pay-out regular small prizes. As a result they’re often popular among players with limited budgets playing with low stakes, spinning out time on device to a maximum. Many players also find the whole experience more entertaining when they win more often.

High Variance Slots

Then you’ve got high variance slots that feature larger but less frequently awarded prizes. More often than not, big payouts are generated via bonus rounds as opposed to the actual base games which means that until and unless you trigger the bonus round, your bankroll will steadily dwindle. Unfortunately, high variance slots can drain your budget pretty quickly, even if the RTP is the same as a low variance game and you’re playing at a low spin value. This is why they’re better suited to high-rollers, who are financially and psychologically equipped to absorb the cost of waiting it out.

The main takeaway here? Although a slot’s RTP can prove helpful, it’s better to rely on variance in determining financial risk over the shorter term. Once you know this, you should then cut your coat according to the cloth. If you’ve got a small budget, stick with low variance games while also keeping in mind that the best RTP slots don’t necessarily guarantee the best payouts.

Using High RTP Slots to Clear Bonus Wagering

So let’s say you got lucky with your welcome bonus and got a big win.  Now, you have to play your winnings through 35 times or more (as much as 65 times at many sites) and hope to have something left at the end of it.  A high RTP slot (98% or more) with a low variance is just the ticket, right?

Wrong!  If you can do those sums, so can the casino – and the vast majority of online casinos have taken steps to prevent you from using those juicy high RTP games to clear wagering requirements.  Check the terms and conditions and you’ll most likely find one or more of the following:

  • A list of games that contribute to wagering requirements at a lower rate than usual.  With a game that contributes at 50%, each £100 of play only clears £50 of wagering, so a 35x wagering requirement effectively becomes a 70x wagering requirement.
  • A list of games that don’t contribute to wagering requirements at all.
  • A list of games that can’t be played with bonus, only cash.
  • A list of games that are not to be played at all, even for cash, if the player has a bonus active (or else the bonus is confiscated).

Pretty harsh, eh?  Good luck finding any high RTP slots that aren’t on the list! A slot in the medium to high RTP range may not be included, though – as long as it doesn’t have other features such as bonus progression that casinos take a dim view of.

Progressive Jackpot Slot RTPs

As far as progressive jackpot slots are concerned, RTP can be quite misleading as it may be quoted with or without the progressive jackpot contribution. Progressive jackpot games are super high variance, of course – it’s all about extremely infrequent, extremely large wins! As it’s almost certainly NOT going to be you that wins the progressive jackpot, there’s an argument for looking at the RTP excluding the jackpot if you want to see how quickly the game can drain your cash, but these days it is most frequently specified including the jackpot.  Some progressive jackpot slots have a lower RTP than non progressive games even when you include the jackpot contribution.

Buy the Bonus Round, Super Bet etc

Extra bet options, particularly those from Barcrest, allow you to buy access to extra features such as linked spins, special mystery pay-outs and additional pay-lines, or increase the number of certain types of symbol in the game, either increasing the chances of triggering the bonus round or increasing the winning potential of the bonus round once triggered. In many cases, the game’s RTP is slightly better with the bonus bet (or whatever ) active than it is without.

Look out for Adjustable RTP Slots!

As mentioned on our new slot games page, operators are now encouraging developers to offer their games with adjustable RTPs. This practice has become really prevalent over the past two years with many of the big operators including the option, among them NetEnt, Red Tiger and Play n’Go.

For instance, Princess of the Forest has an RTP in the range of 94.85% to 97.80%.  And there are now hundreds of other slots with variable RTPs including the likes of Starburst which features an RTP range of 90.05% to 96.09%.

Obviously, the problem here is that operators are able to lower a slot game’s RTP (let’s take it as a given that raising the RTP isn’t foremost in their minds). While some gamers wouldn’t sweat such discrepancies, they can have a big impact.

So when you happen across a game with a seemingly high return to player rate, be sure to check the RTP at your chosen casino before playing.

Which Developers Offer the Highest RTP Slots?

Swedish developers NetEnt have rolled out a raft of high RTP slot games such as Bloodsuckers (98%), Devil’s Delight (97.6%) and Kings of Chicago (97.8%). Microgaming is also known for releasing slots with above average RTPs, most of which are in the 96% range; for example, the classic Immortal Romance has RTP of 96.86%.  Playtech includes a decent collection of high RTP slots like Goblins Cave (99.32%), Mega Joker (99%) and Alchemist’s Lab (97.32%).

What you probably don’t know is that there is one site where all but one of the games has RTP of 98% or more, and that is Tombola Arcade.  Their selection of instant win games includes Spin, a suite of 11 different proprietary slot games with RTP of around 98.5% and there’s another game, Pick, which comes in at a whopping 99.6%.

Online Slots vs Land Based Slots: RTP Range

Believe it or not, most online slots feature considerably higher RTPs than their land-based counterparts, which typically have return to player rates of around 85% – rather miserly in comparison to the 96% average with web-based games. The main reason for this discrepancy comes down to expenses. To begin with, bricks and mortar operators usually lease their cabinets from the developers and must pay them a percentage of all winnings. Then you’ve got the normal costs of running a casino as well as the fact that venue owners only have a limited number of slot games with which to generate a profit and each machine can only be played by one player at a time. As a result, the RTP dial is turned right up for most physical slot machines. Online casino and bingo operators are under no such pressures and can therefore serve hundreds of the best online slot games at a far more favourable RTP.
