Mega Moolah – Few slot machines capture the imagination like Microgaming’s Mega Moolah. It is a progressive jackpots slots with four different jackpots.
The benefit of playing any of the highest payout percentage online slots is of course that you are going to get, over the long term, many more winning spins on those slot and will always get more play time from your bankroll and a much higher percentage of your stakes being paid out to you as winning pay-outs.
However, I can tell you for sure, that when you do go on the hunt for the loose online slots that are available to all slot players you can spend many hours, if not days checking out the RTP’s of such slot games, and no player is going to want to waste their time.
Therefore what I have done in the following guide is to do all of the research for you, and as such I will now be presenting to you the highest RTP slots online, and will also let you know which game providers have launched and designed those slot games.
That will then put you in the position whereby you can track down any casino site offering those higher paying slot machines, and can pick and choose just which casino sites to play at, based on other factors such as bigger and better bonuses, generous comp clubs and rapid winning pay-outs too.
1. Mega Joker Slot – RTP 99.00%
With its certified RTP of 99.00% there really is a lot to like about the Mega Joker slot and whilst it is a slot with a 3 reel, 5 pay-line playing structure, it will be slot that you can always rely on to deliver you with plenty of winning pay-outs.
The Mega Joker slot can be found at all casino sites offering the ever-growing range of NetEnt designed slots, all of which are fully licensed and regulated by the way.
2. Jackpot 6000 Slot – RTP 98.90%
Having launched literally hundreds of great playing slot machines over the years, it will not surprise you to learn that the second top paying online slot by virtue of its RTP is another NetEnt designed slot, that being their Jackpot 6000 slot machine.
That slot, much like the one above has been designed as a basic playing 3 reel, 5 line slot, and you are bound to want to give it some play time sooner rather than later once you discover its long term expected pay-out percentage is a whopping 98.90%.
3. 1429 Uncharted Seas Slot – 98.60%
Whilst the first and second slots with the highest RTP’s are the older styled classical slots, there are plenty of video slot games that do come with above average pay-out percentages, and the next one worth tracking down and playing is the 1429 Uncharted Seas slot.
That is a slot on which some huge winning pay-outs can be achieved via both its base game and bonus game, which is a set of free spins, and it’s a multi denomination slot game too and one has been designed by Thunderkick and has a verified RTP of 98.60%.
4. Blood Suckers Slot – 98.00% RTP
Never be under the impression that you are going to have to pay the slots boasting the very highest pay-out percentage online for high stakes, and each of them do come with fully configurable staking options, that put you in full control over the stake levels you can play them for.
If you do find yourself playing at a casino site offering you the range of NetEnt designed slots, then do make sure that you give the Blood Suckers slot game a whirl, for by doing so you will be playing a Vampire themed slot and one with a high RTP of some 98.00%
5. Starmania Slot – RTP 97.87%
Low to medium variance slots are as popular as ever with slot players, as too are the range of NextGen Gaming designed slots, and you will find that all their slots have stunning graphics and some very highly advanced sound effects too.
You are not going to have to look too hard to find a casino site offering their range of slot games, but one that you should be making a beeline to play is the Starmania slot, which has been set to return to plays over the long term 97.87% of their stakes as winning pay-outs.
6. Kings of Chicago Slot – 97.80%
I do hope you have now got plenty of slot games to add to your list of higher paying online slots, however there are still plenty of other slots that are going to be worth checking out and playing, such as the Kings of Chicago slot game from NetEnt.
That slot is unusual in as much as the reel symbols are all playing card symbols, and I would advise you to read through its pay table to get an idea of the very unique winning combinations that can be spun in and formed when playing it online and the bonus game on offer too, for you will find it a fun slot to play and a higher paying slot too thanks to its 97.80% RTP.
7. Devil’s Delight Slot – 97.60%
When it comes to finding the best slots to play online, the devil is always in the detail, which is a great introduction for the next slot with a higher than average pay-out percentage that you can play online that being the Devils Delight slot.
A fun to play video slot that does of course offer players all the unusual play configurable option settings which include a speed play setting and auto play option, and one thing you will love about that devilishly good NetEnt designed slot games is its 97.60% RTP.
8. Retro Reels Extreme Heat Slot – 97.50%
There is no doubt in my mind, that many of you slot players out there will have played Microgaming designed video slots before, and probably do always tend to play them regularly too, and they can be accessed by a downloadable and instant play gaming platform and a mobile casino app too.
One slot that you need to get stuck into playing to have the maximum winning chances at any casino site offering Microgaming designed slot machines is the Retro Reels Extreme slot, as it is a video slot on which you will find an RTP of a fabulously high 97.50%.
9. Simsalabim Slot – 97.50%
It isn’t too unusual to find more than one online slot that has been set to return a pay-out percentage of the exact same amount as some other slot games over the long term, and as such allow me to introduce you to another slot that comes with the same RTP as the above slot.
That additional slot though is part of the NetEnt collection of video slots and goes by the name of the Simsalabim slot, it’s a slot also boasting a magic type of themes and its RTP of 97.50% should ensure you get a fair amount of play time out of your gambling budget too.
10. Jack Hammer 2 Slot 97.10%
There are now two slot games from NetEnt that make up the Jack Hammer series of slots, however I should point out that if you have only played the original version of that slot you really do owe it to yourself of play the second slot in the series instead.
The reason for me saying that is that the Jack Hammer 2 slot is a game that boast a slightly higher and much more appealing RTP than that of the original game, and for reference that long term expected pay-out percentage has been set at 97.10%.
Single Session Slot Game RTP’s
One final aspect to playing slot machines, including each of the top 10 slots with the highest RTP’s that all players do need to be fully aware of, is that those slots are completely random, and as such you could win or lose when playing them.
On any one single slot playing session, that does of course mean that even though for example a slot such as the Jack Hammer 2 slot has been set to return a pay-out percentage of 97.10%, you are unlikely to achieve that exact pay-out percentage on every session that you have playing it.
But over the long term the more that you do play any slot the much more likely you are to achieve its pre-set RTP, and you could of course achieve a pay-out percentage of over 100% or a pay-out percentage much lower than the one it has been set to return to players.
However, make no mistake about it, when you do set about playing low paying and higher paying slots you are soon going to notice the difference in the type of gaming session you do have, as you are much more likely to spin in many more winning combinations, and trigger many more potentially huge paying bonus game feature rounds when playing those slots with the highestpaybacks.
So make sure that you do have each of those slot games listed up above higher up on your list of slots to play online, when you next fancy spinning some slot game reels online, as they are the very best ones you can play currently.

Every slot machine that you play at an online casino has their own Return to Player (RTP) percentages. The RTP determines the odds of making a profit during a session. The higher the RTP, the less of an edge the house has over you. In short, with a higher RTP percentage, you stand a better chance of making a profit.
Return to player – Understanding payouts
The minimum percentage is usually 85%, but a solid payback percentage is between 95% and 97%. Keep in mind that slot machines with higher bet denominations also come with higher percentages for payouts. But be aware, if you come across a slot machine with a very high RTP (+98%), you probably can’t trust it. Legal and verified online slot machines have a maximum RTP of 97%. Anything higher is unlikely to be legal or appear on trusted sites.
Online slot machines that pay the most
Out of the hundreds of online slot machines, some are of course more profitable than others. In general, a reliable online casino advertises its most profitable slot machines. After taking a closer look, we distinguished two kinds of machines; video slots and progressive slots. Video slots have the highest payout rates. The best performing casino sites have pay-to-player percentages that can be as high as 97%. By contrast, progressive slots can win you the most money, but with a lower Return to Player. Our experts conclude that video slots are the preferred choice because you can win more often and there are still huge jackpots.
