Our top 10 list of best-paying slots

It might be hard to determine the top 10 best-paying slots ever, but not impossible. Nothing is truly out of the question for me, and this falls under that category. So, let me introduce you to the top 10 best-paying slots, right here on Casino Hipster.

What are the best-paying online slots of all time?

Let’s get straight to the point! Below you see our list of the top 25 best-paying slots of the most prominent slot providers.

The best-paying slots are the slots with the highest theoretical Return to Player (theoretical RTP or simply RTP).

With so many slots out there, you have more than enough options to choose from.

Yes, you can look at the slot’s attractiveness in terms of animations, smoothness, gameplay or variance.

But it is also essential to look at the RTP of the slot. After all, you want a fighting chance at beating the casino, don’t you?

I looked at the RTP’s of slots of 23 providers, all released from 2011 till September 2023.

RTP Comparison with other slots

Below, the RTP of these top 25 slots (red dots), compared to the payout rates of  1660 other slots of 23 providers (grey dots).

The green line is the average RTP of online slots, which is 96.2%.

Why a higher RTP matters

The higher the RTP, the more you benefit. For example, take an RTP of 96%. In that case, you can expect to lose $€4 for every $€100 you spin. But would the RTP be 97%, your expected loss would “only”  be $€3.

Is the 1% difference so relevant? More than you think. If, for example, your starting balance is €100, the difference is $€1. But remember that you also wager your winnings. So in a session, your total staked amount could easily top €500. In that case:

• If the RTP is 96%, your expected loss amounts to: $€500 x 4% = € 20
• If the RTP is 97%, your expected loss is: $€500 x 3% = € 15

So, you already see that the difference is more substantial. And it becomes more and more so once you start to wager higher amounts.

The RTP has nothing to do with the slot’s volatility (or variance) for the avoidance of doubt. Variance says something about the variation of the sizes of wins. High volatility slots pay more top prizes (but less often).

Low variance slots payout smaller prizes and (on average) more often. Thanks to the volatility of slots, it’s possible to win big!

So, tell me more about these best-paying online slots

CasinoHipster loves to play slots and will seek out the best-paying slots where possible.

Here are some of our favourite high-paying online slots:

Book of 99 (Relax Gaming, released in 2021): RTP of 99.00%

Relax Gaming just released Book of 99  (September 2023). It’s outstanding for many reasons, but the fact that the RTP is 99% is truly unique!

Book of 99 is captivating as well. Yes, there are many more Book of Ra type of slots, but this one has something extra. You can trigger the free spins in 2 different ways, either by spinning three books at once or by collecting 99 (our magical number!) books!

Mega Joker (Netent, released in 2011): RTP of 99.00%

Mega Joker has the more familiar classic features, such as three reels in the main game and three upper reels in Supermeter mode.

Mega Joker has the highest RTP of 99%. However, this only applies in the top game with the three upper reels, and only if you play the maximum bet.

The variance of Mega Joker is medium to high.

1429 Uncharted Seas (Thunderkick, released in 2016): RTP of 98.60%

Thunderkick’s 1429 Uncharted Seas slot is an absolute pleasure to play. The slot looks fantastic, and the bonus rounds are also entertaining and sometimes pretty rewarding.

The theme of this new title is the mythical sea stories from the 15th century.

What’s also striking: the payout rate of 98.6% is exceptionally high.

The volatility is low, and the maximum win is 670x the bet.

Marching Legions (Released in 2016): RTP of 98.12%

Relax Gaming is becoming more and more of a serious provider, and some of their 2020 slots are stunners! Think of slots like Money train 2, Hellcatraz or Iron bank. But they also released Marching Legions, which has an outstanding RTP.

The RTP of the Bonus Buy Feature is also a lovely 97.13%.

What I also like is the high volatility of this slot. Most slots of this list have a low variance, but not this one!

The Catfather (Pragmatic Play, released in 2016): RTP of 98.10%

Pragmatic Play has based this slot on The Godfather, with a twist. Nevertheless, more than entertaining, What helps is the fantastic payout rate of 98.10%.

So effectively, you are “only” giving away 1.90% to online casinos. Yes, you can outsmart them. If you can use this slot to unlock your bonus money, why not do it?

The volatility of this slot is low: you will not see any mega wins here.

Blood Suckers (Netent, released in 2013): RTP of 98.00%

Netent’s Blood Suckers is a fantastic vampire-themed slot with excellent animations.

In the main game, there are 25 paylines. In addition, the game has free spins as well as a Pick and Click bonus.

The variance (volatility) is low. It implies that there are relatively many smaller wins, not massive wins.

Jokerizer (Yggdrasil, released in 2016): RTP of 98.00%

Jokerizer is a mix of a fruit slot and a video slot, with limited features.  Thanks to Mystery Wins, you can win big.

Yes, the RTP is 98%, but this is only when you play the Jokerizer Mode. If you don’t, the RTP drops to a poor 88,8%. Our advice: always play in the Jokerizer Mode.

The variance is medium to high. The max win is 600x the bet. So you can expect mega prizes of around 500x to 600x the bet, relatively often.

The Ruby (iSoftbet, released in 2018): RTP of 97.50%

The Ruby is a Jackpot slot with 5 reels and 3 rows of symbols. There are 30 paylines.

The slot looks a bit retro, and the bonus feature is like a “Big Bertha” slot where you pull the handle to get either a mystery win, free spins or one of 3 jackpots.

Yes, the RTP is excellent, but a part is attributed to the jackpots, which is only for the happy few. It would help if you liked these kinds of slots.

Big Bad Wolf (Quickspin, released in 2016): RTP of 97.34%

Big Bad Wolf is a fairytale where three little piglets are hiding from the big bad wolf.

This award-winning video slot has progressive wilds, free spins, retriggers, three cute piglets and one angry wolf.

The gameplay is excellent, and the RTP as well. The variance is low to medium.

Børk the Berzerker (Thunderkick, released in 2018): RTP of 97.30%

It’s an entertaining slot with 5 reels and 3 rows of symbols. It’s a cartoon slot with a Norwegian “berserker” theme. The animations are spot-on, and it just looks good.

The gameplay is entertaining and offers more than enough variety.

The volatility is medium, and the maximum win is 2,100x the total bet.

White Rabbit Megaways (Big Time Gaming, released in 2017): RTP of 97.24%

It is a special mention for this slot, even if it’s outside the top 10 list (15th spot):  White Rabbit Megaways.

For starters, it’s the best paying Megaways slot. Then the slot itself: it’s magical. There are 5 reels up to 7 symbols in the main game, but these can expand to 12 symbols in the free spins.

So you can end up with 248,832 Megaways in the free spins.

Did you also know that this was the first Feature Buy slot? With the Buy a Bonus feature, you get immediate access to the free spins. In that case, the RTP is a more than fantastic 97.77%!

Beware: unlocking bonus money with high-RTP slots is not always possible

An obvious question is whether you can use these slots when you want to unlock bonus money.

My advice is to check the terms and conditions of the online casino.

For example, many casinos will not allow you to play slots with an RTP of, say, 97% – 98%, with bonus money.

It would otherwise be too easy to convert your bonus money into real money. But having said this, you can play these slots with real money.
