What Is a Payback Percentage?

The payback percentage—also known as the payout percentage or return to player—is the amount of money deposited into a slot machine that is eventually paid back to the customer. This percentage is not determined in weeks or months, but rather over the life of the machine.

For example, let’s say that $100,000 is inserted into a slot machine with a 92% payout percentage. According to the RTP (“return to player”), the slot should pay back $92,000 of the wager in the form of wins, while keeping the other $8,000 in profit. Keep in mind, however, that the true payout of a slot machine may take millions of spin to determine.

When a machine’s software is written at the factory, this is when the payback percentage is set in accordance with local laws. For example, slots in New Jersey must be set to pay back a minimum of 83%, while games in Nevada have a lower limit of 75%. On average, the payout percentage for most slots ranges from 82% to 98%.

Slots with a high RTP are known as “loose slots,” while their stingy counterparts are referred to as “tight slots.” Since these figures are rarely reported, it’s difficult for a player to accurately determine whether the machine they’re playing is loose or tight.
In previous years, the RTP was set at the factory and any additional manipulation by the casino required the software to be switched. Thanks to advances in computer technology, many casinos can now remotely manipulate the odds and payout, although they must wait until the machine has been vacant for at least four minutes (no mid-game manipulations).

How to Find the Highest Paying Slot Machine

Casinos love to promote their slots as being loose or easy to win slot machines, but they’re tight-lipped when it comes to actually identifying the machines. In most cases, a few loosest slots are sprinkled into rows of tight machines, which still give the casino the opportunity to brag about all the loose slots they offer.

Unless you happen to have a casino manager in your back pocket, it’s going to be difficult to determine a game’s true payback percentage. Gambling forums and chat rooms are often filled with people who claim to know the RTP for various machines, but you should only trust those sources with impeccable credentials. Otherwise, it’s probably an educated guess or outright lie.

Games with Top Payback / Payout Percentages

While it may be disappointing to hear, a so-called list of loose slot machines is useless. There are a couple of reasons for this, which I will explain below.

Varies by Machine – Just because one slot machine from a certain series pays back 96%, another identical machine may only pay back 89%. These differences aren’t listed by the casino, so the player is left to play a guessing game.

Location – Even if you somehow learn that the fifth machine on the fourth row pays back 97%, it’s only a matter of time before the casino changes its physical location.

When searching for the best RTP, the best strategy is to look at the minimum paybacks allowed by law. Any law-abiding casino cannot go below this number, which at least gives you a worst case scenario for the rate of return. Unfortunately, not all states have a minimum, and establishments aren’t always required to disclose their payback setting (especially Indian casinos, who regulate themselves). Still, I’ve included what meager information I could gather.

• Arizona – 83% minimum payback
• Delaware – Their video lottery terminals must pay between 87% and 95%.
• Kansas – 87% minimum (80% at Indian casinos)
• Louisiana – Casino slots must pay no less than 80% and no more than 99.9%. The minimum return at locations other than casinos is 80%, with a maximum of 94%.
• Maine – 89% minimum payback
• Maryland – 87% minimum payout
• Minnesota – RTP must be between 80% and 95%.
• Nevada – 75% minimum RTP
• New Jersey – 83% minimum payback
• New Mexico – Between 80% and 96%, although Indian casinos have a required minimum of 80%.
• North Carolina – Payout must fall between 83% and 98%.
• North Dakota – Slots carry a minimum return of 80%.
• West Virginia – Carries of minimum requirement of between 80% and 95%.
• Wisconsin – Minimum return of 80%.

Slots with the best payback percentage are highly coveted in the world of gambling, so expect a feeding frenzy whenever a game’s true RTP becomes known. This doesn’t happen very often, though, as casinos love to move machines around to keep savvy patrons guessing. Ultimately, your best chance comes from reading the rules, understanding the pay table, and keeping your expectations in check. Once you meet these requirements, you’re a lot more likely to walk away from the casino with a smile on your face.

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%

Best Payout Slot Machines Lake Tahoe

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.

Beau Rivage Best Payout Slot Machine

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.
