- High RTP 3 Reel Mobile Slots. There will be a slot game or a group of slot games that you are going to find very appealing no matter at which of our featured and fully licensed casino sites you choose to play at, and as such you are going to have a very enjoyable slot playing session when you do sign up to those casino sites.
- Have you ever wondered which slot machines have the best odds? If you’ve ever played at a land based or online casino before, then you probably know that there is a huge amount of machines to choose from, and this can be a bit daunting and confusing for a lot of people. Sure, some people just pick the games they are most attracted, however there are others who are in it to win it, and could.
The best-payout casinos are easy to find online. Several publications offer details of the payout rate for the top Internet casino sites. You might only be able to find one month per year that is closely covered (at least for online eyes), but you can extract a lot of information from the data offered.
That isn’t to say the numbers give a perfect view of how much casinos seek to pay back gamblers. Just like live casinos, the online websites can’t manipulate their numbers so well that they can hit their target numbers on the dot. For a game of chance to be legal, you have to be gambling on the odds. But the house edge yields a set of probabilities that the final numbers should get close to, especially in the casinos with a high volume of play. The more hands, spins, or rolls are bet upon, the more likely the expected return is likely to look like the final payout rate.
We’re starting off the list with the best payout slot machine, which has an RTP of 99.07% - Ugga Bugga Slot. That’s right! That’s right! We’re talking about the highest RTP slot in our selection that runs on the Playtech software platform.
Online Casinos with the Highest Paying Slot Machines

What Payout Reports Mean
As I mentioned, just because one casino sits at the top of one month’s numbers, that doesn’t mean they will do that the month before or the month after. Over the course of a simple 30 days, a lot of deviation gets into the numbers. The expected payback on a site’s most popular slots might be one number, but one big jackpot can throw those numbers way off for the month. Or the lack of a big payout can lower the overall numbers for a casino which plans to have the lowest house edge–therefore they highest payouts. As they say, it’s gambling.
Still, the numbers are what they are, meaning past numbers are the closest answer you’ll get to which casinos are offering the best odds now. Casinos can say they offer this or that, but unless you’re willing to crunch the numbers on all the games (or know the payouts on your favorite games by heart), it’s hard to say which offer the best games. My suggestion is you learn the expected return on your favorite games and know how to spot alterations to the basic formula. If you like blackjack, learn what a switch from 3:2 payouts to some other ratio means to the odds of a game of blackjack. Know how to spot the best video poker games, along with how to learn whether an online casino offers imprisonment rules on their double-zero roulette. These are the ways you’ll assure you have the best odds online. Now let’s look at some numbers.
Summer 2015 Payout Reports
The numbers I list below are the total payout reports for all games at the following top casinos, including blackjack, craps, roulette, keno, video poker, slots, specialty games, and other assorted table games. I did not include the numbers for the slot machines by themselves, because I wanted to show which casinos offered the best all-around casino experience over the period covered (mainly June of 2013).
- 97.35% – Bet365 Casino – Playtech Software
- 97.25% – Ladbrokes Casino – Microgaming Software
- 96.95% – Mummy’s Gold Casino – Microgaming
- 96.81% – 32 Red Casino – Microgaming
- 96.60% – 888casino – 888 Proprietary Software
- 96.53% – William Hill Casino – Playtech
- 96.13% – All Jackpots Casino – Microgaming
- 95.77% – Spin Palace – Microgaming
- 94.93% – Party Casino – Party Gaming Software
You’ll want to cherry-pick information to suit your gaming needs, while you’ll want to know how to analyze the numbers and to learn which site gives you what you want.
For instance, Spin Palace Casino sits near the bottom on this list, but this was hurt by their incredibly high house edge on their slot machines (92.11% payouts for a gigantic 7.89% house edge). I’ll guess Spin Palace didn’t pay out any big progressive jackpots that month, which lowered their overall payouts for the whole month on everything. Since slots make up as much as 70% of the revenues for certain casinos, those low numbers hurt their final payout rates (from a player’s perspective). But if you weren’t playing the slots, that means the payouts on the other casino games like blackjack, craps, and roulette were much higher. This would lift the table game numbers to the top of the rankings.

Just so you’ll know, the best payouts on the slots for the month were Mummy’s Gold, 32red, AllJackpots, and Jackpot City. These were the seven casino sites with final slots numbers over 96%.
Best Payouts on Table Games
Since the top payout casinos like Ladbrokes and Bet 365 weren’t listed among those numbers, that means their table game payouts were off the charts. Since blackjack, roulette, and craps don’t have big progressive jackpots to pay out, the deviation on these games should be flatter from month to month. That means you should expect better blackjack odds from Bet365, William Hill, Ladbrokes Online, and 888 Casino on a monthly basis
Top Payout Rates for Online Casinos
These numbers are changing constantly, of course. Even the numbers offered are still a small idea of the wider world of online gambling out there. The poker rooms, sports books, and racing books associated with each of these brand names would likely look a whole lot different. Other online brands might offer better odds, if you looked at more of the Playtech and Cryptologic payouts, or you looked at online software development companies like IGT, RTG, or Rival Gaming. The numbers listed were supposed to be the best for the month, but even these might be cherry-picked by the presenters, hoping to lure you to their favorite casinos. That’s why I wanted to give a report based upon all the information I had and not some sampling. I wish a list of comprehensive payout numbers for online casinos existed in one place, but with all the online operators, software design companies, licensing authorities, and jurisdictions, that would be a tall order. These should give a good idea of the payout numbers for some of the top casinos online, though.
Games offering progressive jackpots and bonus rounds are popular with players, but slots with the best payout rates or payback percentages are considered among the top prizes in the world of gambling. After all, even a couple of extra percentage points can make a major difference when calculating the profitability of an individual slot.
This article examines the definition of “payout percentage” and explains where to find the most generous slot games. While it won’t improve your actual chances of winning, the knowledge that you’re playing a more liberal slot machine should at least boost your confidence.
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.
Best Payout Slots At Casinos
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.
