Online slots are the most popular type of game in the iGaming industry and it’s not even close. Millions of people love spinning real money slots mobile or online, always looking for the best slots to play. That’s easier said than done. While there are thousands of slot games on the web you can play, not all of them pay equally or substantial sums of cash.
Online slots differ from their Vegas counterparts. They are much more complex and controlled by a device known as Random Number Generator that randomizes each spin. In that way, it ensures fair results. The top paying slot machines can’t be hacked – they either pay great money or don’t, depending on their payout odds. Since online slots are games of chance, you need to understand how top paying slot machines work before you play them.
Of course, spinning slots for free will give you an excellent overview of what to expect. Considering how many slots you can find online, it can be a Herculean challenge. The good news is that in this guide, we’ll tell you how to spot the slot machine with the best odds of winning and raise your chances at big money payouts. When you feel ready, you can join DraftKings Casino or the BetMGM Casino app to play them for free or real money.
Which Slots Qualify as Best Paying Slot Games?
You’ve probably come across ads of casinos with highest slot payouts, but what does that even mean? In order to learn how slots work, you have to understand a few terms. The key ones are RTP and variance/volatility. Players consider high RTP slots better-paying, although you may come across low and medium volatility slots that deliver solid wins.
Let’s take a deeper dive in both terms and explain how they determine the best slot machines to play online, so that you can device your online slots strategy.
RTP stands short of return to player. It’s a number displayed in percentage, showing the theoretical expected returns per slot. The best paying slots will have a higher RTP of over 97%. Of course, those come rare as the goal of casinos is not to lose money.
A percentage of 100% means that the odds are even and that it’s a game with no house edge or casino advantage. Those are the highest payout slot machines, yet such a game doesn’t exist. Few slots have come close to that magical number, but no developer or operator will ever create a game that pays on 100% of spins.
Many players confuse the best paying online slots as guaranteed money-making machines. That’s not the case. We already mentioned that the RTP number is theoretical. It shows the expected returns over a number of bets but doesn’t guarantee wins all the time.
Let’s put things into perspective. Your favorite slot has a solid RTP of 96.5%. You play it a few days per week with wagers that total $1,000. On average, the machine will return up to $965 in winnings in that period. It’s a statistical advantage, not a guaranteed return. The larger the spin sample size, the closer the number will be.
While high RTP doesn’t guarantee wins, you should always pick the best paying slots. Statistically, they pay better than other slot games, and that’s why you should go with them. Before you choose a slot machine just because of the high RTP number, you should also learn about slot variance. And keep in mind that 888 slots and BetMGM slot games carry some of the highest RTP rates you will find in the US.
Does Variance Matter?
Yes, it certainly does. Variance, also known as volatility, refers to the frequency and size of the average winnings across. There are three types of slot volatility:
- Low variance: many players will say that the best slots to play are low in volatility. These slots pay frequent wins, but of the smaller variety.
- Medium variance: medium variance slots pay varied wins, so expect frequent smaller wins and the occasional big one.
- High variance: the slot machines with the best odds of winning are highly volatile. However, these slot games usually feature long dry spells, so it may be a while before you score a win. Caution is advised when spinning these slots, especially when playing at a casino with $20 or less. You should be careful with your bets as things can get ugly, even when you’re choose the bests slots to play. The good news is that when they pay, they pay big.
In most casinos with highest slot payouts, the volatility won’t be displayed publicly. You can find this information on the game’s guide, or by reading BetRivers slots and Betway Casino slots reviews. If the developer doesn’t show it too, you can go for a demo version and spin the slot 100 times or close. Record the wins you hit – if they are small and frequent, it’s a low variance slot game. If the opposite happens, the slot is highly volatile.
If you get small and big wins, the slot is of medium variance; like several Borgata Casino slot games are.
In general, slots of low volatility such as Starburst pay often. Highly volatile slot games, which you can find in the Caesars Slots list, usually carry wins worth tens of thousands of times your stake, and sometimes progressive jackpots too. For example, Mega Moolah has a stunning jackpot on offer and high variance, but low RTP so you can’t hit it easily.
Highest Payout Slot Machines
Instead of looking for the best paying online slot games yourself, we’ve compiled a simple list for you. It features the most popular slots with high payouts, even if the RTP ranges are not that high. Just because a slot has a higher RTP doesn’t mean it pays solid due to the variance. The slots you’ll find below are rated by their payout size and frequency, which puts them on the list of best paying slots. For more high paying slots, check out DraftKings Casino slot games and FanDuel online slots.
Monopoly Big Event – 99%
There have been plenty of Monopoly slot games so far, and they all come with great winning potential. However, Barcrest’s Monopoly Big Event takes all the plaudits as one of the top real payout slots in the industry. The base game has an RTP of 96%, but in the Big Bet game, it shoots up to 99%.
Monopoly Big Event is inspired by the popular board game. It has 20 fixed paylines and vintage slot gameplay, so it’s not hard to spin at all. The Big Bet event is a special bonus round where you can win the top rewards. All wins during the Epic Spins are boosted with an x5 multiplier, with guaranteed wins also in the mix.
It’s one of the best Monopoly slots to date, and one we can highly recommend as the best slots on BetMGM casino.
Book of 99 – 99%
One of the newest slot on this list, Book of 99 by Relax Gaming has a 99% RTP as its ace in the sleeve. The slot comes with 10 paylines and high variance as well as maximum wins of just over 12,000 times the stake. It’s a game that perfectly blends the Book of… theme with Hommer’s Odyssey in a cartoon style slot game with sky-high returns in theory.
Just like most Book slots, this slot doesn’t reinvent the wheel. It doesn’t have that many features, but it has a great backstory and solid visuals. Of course, it’s a highly volatile title so you should be careful with your bets. Thanks to the Book and Wild Collection features, the variance is slightly softened, although not as much as we hoped.
The good news is that the slot has a free spins round with an expanding symbol that’s become a trademark feature of Book slots. With it, you can hit the biggest possible win in the game, making Book of 99 one of the best slots to play on the Internet. The only two other slots that can match its return to player rate are Mega Joker and Ugga Bugga.
Starburst – 96.09%
Here’s a slot that doesn’t shine with RTP, but it widely considered the best ever. Developer by NetEnt, Starburst’s technical stats are not that impressive. It has low variance, RTP of 96.09%, and 10 paylines, even if they pay bothway. The winning potential is not remarkable either at 600x the bet. What’s most striking about this slot is the low variance that all but guarantees regular smaller wins and the occasional bigger one.
The key to big wins is in the Starburst wilds. These expand whenever they land to help you score big wins. Land them often and you’ll realize instantly why many consider it the best online slot USA. It’s also one of the few slot machines with the best odds of winning, making it an all-time favorite of thousands of players.
As mentioned, it may not impress visually or technically, but on a prize level, it’s one of the top paying slot machines.
Bonanza – 96%
Australian developer Big Time Gaming is widely known for inventing the popular Megaways engine many slot developers use these days. It’s a high-paying gameplay engine that doesn’t rely on traditional paylines. Bonanza gives players thousands of ways to win for symbols on adjacent paylines. Bonanza is one of the most successful Megaways slots of all time. It comes with high variance and an RTP of 96% and features the iconic 117,649 ways to win.
At its core, this is a straightforward slot. BTG didn’t invest a lot in visuals, instead focusing on the payouts. The mining theme may not work for everyone, but we can all agree that it’s among the top paying slot machines. With a winning potential of 26,000x the stake, this is one of the best casino slot games you can try. For more Megaways games, check out the Golden Nugget Casino slots.
Thunderstruck II – 96.1%
Thunderstruck made the headlines when it first released in 2004. It was a medium variance slot with a high RTP (for the time) of 96.1% and 9 fixed paylines. The slot’s real highlight was a free spins round with tripled wins, but it all came crashing down when Microgaming unveiled its sequel Thunderstruck II.
Released in 2010, it’s still one of the best paying online slots a decade later. The RTP is higher at 96.65%, and so is the variance. This time, Microgaming went with its famous 243-ways to win mechanic, giving players better chances to win. On top of it all, it has extra features over the original and maximum potential wins of 8,000x the bet.
It’s a Norse mythology slot to the likes you’ve never seen before. If you ask us, it definitely deserves its spot on the best slots to play list.
Guns N’ Roses – 97%
NetEnt’s Guns N’Roses slot will definitely take you to Paradise City. Part of the studio’s trilogy of music-themed slot games, Guns N’Roses features the iconic band and some of its hits in a package with an RTP of nearly 97%. It has 20 paylines and low to medium variance which means you can expect solid returns for your bets.
While the winning potential is ‘only’ 1,250x the bet, this is a slot that pays more frequently than the others on this list. That’s what makes it one of the top paying slot machines in the industry, and a must try for all players.
Wheel of Fortune Megaways – 96.46%
The Wheel of Fortune TV show is known for its fantastic rewards and Big Time Gaming certainly aimed for that winning potential in Wheel of Fortune Megaways.
