Tired of spinning those reels that end up eating your bankroll? You’re in the right place ‘cause I might know a few of the best high payout online slots.
Why am I sharing them with you? Let’s be real; online slots are games of chance. So we all have an equal chance to win. Besides, I’ve been around the block since the whole digital thing kicked off, and reviewing games has always been a passion of mine.
For a start, you should know that high payout online slots have a return rate higher than the industry’s average of 96%. So don’t settle for less. Some even bring huge multipliers and big jackpots. But not everyone knows how to find them.
I did your homework for you, so relax and enjoy a list of the 7 best payout slots you’ll ever play.
Top 7 High Payout Online Slots
These high-RTP (return rate) slots are an absolute must for slot fans seeking huge payouts. Plus, they’re packed with bonus features, crazy themes, and multiple ways to score big. Enjoy!
#7 Blood Suckers Megaways Slot by Red Tiger
- Launched: 2023
- RTP: 97.66%
- Volatility: High (huge payouts, although less frequent)
- Max Win: 20,521 times your bet
I start the list with a pretty new online slot game.
It’s all about dark castles, an eerie soundtrack, and creepy vamps. The design is 100% more modern than the OG Blood Suckers slot you’ll also find on the list, by the way.
There are a lot of bonus features you’ll get to enjoy, such as wilds and vampire killers, free spins, bonus buy, and, of course, the Megaways mechanic with over 100K ways to win per spin. Plus, reels change size every spin, with wins triggering cascading reels.
That’s a good one to start with, right?
#6 Jokerizer Slot by Yggdrasil Gaming
- Launched: 2016
- RTP: 98%
- Volatility: High (wins won’t rain down on every spin, but when they hit, they do it big)
- Max Win: 6,000 times your bet
If you’ve been looking around for high payout slots, chances are you’ve come across this bad boy. Jokerizer gives retro vibes but with a modern twist. I mean, you’ll play with classy fruit symbols under neon lights and that creepy joker twist.
The setup? Simple. 5 reels, 3 rows, and 10 paylines. Why it stands out? Every time you land a win, you activate the Jokerizer Mode, with your chances of landing mystery wins significantly increased. Yep, no free spins, but the game is already engaging and rewarding.
#5 Blood Suckers Slot by NetEnt
- Launched: 2013
- RTP: 98%
- Volatility: Low (frequent smaller wins)
- Max Win: 1,014x your stake
Anyone into dark and creepy vampire slots? I’m sure you’ve heard about this one, even before mentioning it earlier. It’s got the whole gothic package. Even if this NetEnt slot has been out for more than a decade, the graphics are a whole vibe.
Nothing extra about the gameplay – 5 reels and 25 paylines. Easy to get into. Yet you’ll enjoy some amazing special features like free spins and a real bonus game where you hunt for coin prizes. Not gonna lie, I find it super satisfying and one of the best high payout slots.
#4 1429 Uncharted Seas Slot by Thunderkick
- Launched: 2014
- RTP: 98.6%
- Volatility: Low (frequent small wins)
- Max Win: 670x your bet
Don’t let the year fool you. This slot aged like fine wine.
If you’re in the mood for a vintage sea adventure and a high payout slot, that’s where you’ll find it. You’ll vibe this one. 5 reels, 3 rows, and 25 fixed paylines – classy setup. And symbols like old maps, sea creatures, and compasses will keep you company.
From special features, you’ll get to enjoy expanding wilds and free spins rounds. Yep, no extras but that’s what keeps the game simple yet rewarding.
#3 Mega Joker Slot by NetEnt
- Launched: 2011
- RTP: 99%
- Volatility: High (less frequent big payouts)
- Max Win: 2,000 times your bet
If you’re all about classic games and real gameplay with a massive win potential, you already know where to find it. With one of the highest payouts out there, this online slot is hard to miss.
This NetEnt slot is retro to the core. You’ll play with classy fruit symbols, jokers, and a chunky arcade-style slot machine. Don’t expect fancy 3D graphics or jaw-dropping soundtracks. A pure Vegas-style slot machine but online.
Of course, it’s a 3×3 layout with 5 paylines. But don’t let it fool you. The win potential is real, especially when the Supermeter Mode enters the game, including those Joker mystery wins of up to 2,000x. You won’t even miss a progressive jackpot here, with such a high payout rate.
#2 Book of 99 Slot by Relax Gaming
- Launched: 2021
- RTP: 99%
- Volatility: High (big wins, but you’ll need some patience till they hit)
- Max Win: 5,000 times your stake
The high payout makes this game one of the best online slots. Period.
Forget the most popular theme – Egypt for a sec. Now, Ancient Greece is a big deal. You’ll find everything from warriors to mythological magic here. Everything is wrapped in sharp graphics. You’ll basically deal with the classic layout of 5 reels, 3 rows, and 10 paylines but with a modern twist.
Free spins, expanding symbols, and the collect feature will help you score big. So if you’re sick of low-RTP slots, you’re into high-volatility games, and want a slot with better odds than the Book of Dead, try out this high payout game from Relax Gaming.
#1 Ugga Bugga Slot by Playtech

The list is topped by one of the highest paying online slots in the industry, coming from a giant provider – Playtech. This game has been keeping players glued to their screens since 2006 with its above 99% return rate. So expect a pretty sweet return on your stake, especially if you bet big.
Ugga Bugga has a jungle tribal theme – all about kiki masks, drums, and huts that will take you on a tribal adventure. Plus, things are pretty straightforward, with a 3×3 grid and 10 paylines. You get to enjoy this “hold” feature and lock in certain symbols to up your winning chances.
Ugga Bugga is simple, with constant rewards, and the potential for big wins over time, perfect for newbies, but experienced players who want some chill fun will also like it.
