With online casinos and sweepstakes casinos experiencing a huge surge in popularity, it’s only right to take a look at some of the most popular slot providers in the world.
After all, the main reason why people play inside these casinos is to spin slots.
Whether you sign up with Betsson, BetMGM, FanDuel, or one of the other major casinos, you’re going to find thousands of slots, including MegawaysTM and hold to win slots.
The best part is that these slots come from a range of different providers who all offer their own flagship titles and something different from each other.
So, of the countless slot providers on the market, which are the most popular?
Pragmatic Play is the biggest and most popular slot provider of them all. Over recent years, they’ve released some modern classics, with the sugary Sweet Bonanza and Sugar Rush being the picks of the bunch, as well as the legendary Gates of Olympus. The reason why Pragmatic’s slots remain so popular stems mainly from the huge multipliers and insanely high maximum wins. Not to mention, the slots themselves are extremely well put together and tend to be on the colorful and vibrant side, so players naturally get hooked.
Hacksaw Gaming is still a ‘mobile-first’ provider of casino games to both online casinos and sweepstakes casinos. Outside of scratchcard and instant win games, Hacksaw is a top provider of slots and has released quite a few hit titles since 2018. Double Rainbow, Wanted Dead or a Wild, and Superstar Sevens are some of the standouts, appreciated for their gripping gameplay and highly immersive themes. Hacksaw’s slots have a certain ‘console’ feel to them, almost like you’re playing on a Playstation, and often come with Bonus Buy options, Sticky Wilds, and other epic features. Hacksaw has lots of playable demos as well, so we recommend checking them out so you can see what the experience is all about.
Play’n GO has been in the iGaming business for close to three decades now. In that time, they’ve released iconic slot games and have even released some iconic series over recent years, including the Book of Dead and Moon Princess series. What makes Play’n GO stand out is their simple approach: there’s no overly complicated mechanics yet you find yourself glued to your screen. Fire Joker is a great example of this, where it blends classic mechanics with a simple modern feel. You can’t go wrong with any of their big releases, which is why most online casinos are desperate to stack their libraries with them.
You can find Yggdrasil Gaming slots in close to most online casinos. Founded in 2013, some of the most noteworthy releases from the company include the much-loved Vikings Go Berzerk and Cazino Zeppelin, along with Golden Fish Tank and Raptor Doublemax. Smartly, what Yggdrasil has done is create exclusive in-slot mechanics for some of their most popular releases that you won’t find anywhere else, including the Gigablox™, DoubleMax™, MultiMAX™, and Splitz™ features, which introduce oversized symbols, expanding reels, cascading multipliers, and other novel ways to win. Yggdrasil is very much a provider for the ‘modern’ player, so you’ll want to check their catalogue out if you want a fresh change from classic slots.
Founded in South Africa, Microgaming has been around since 1994. They first caught attention in 1998 following the explosive release of Cash Splash, a legendary progressive jackpot slot, and have since released hundreds more. Mega Moolah is the top pick thanks to its huge jackpots, where a player once won a staggering $21.7 million. Then there’s Gold Blitz Extreme, where players can get 5,000x wins and other awesome perks. If you’re looking purely for big jackpots and the multipliers to go with them, it’s Microgaming all the way.
Relax Gaming is a highly popular provider of poker, bingo, and other slot games, not just slots. But when it comes to slots, they’ve released plenty of classics over the past decade and a half, such as Money Train 2, Temple Tumble, Iron Bank, Snake Arena, and Top Dawg$. All of the slots are mobile-friendly and come with player-favorite mechanics like tumbling reels and bonus rounds with huge multipliers. They come with beautiful designs, too, so it’s no surprise that Relax Gaming still continues to be one of the main slot providers to this day.
If some of the big jackpot, highly immersive slot games from the likes of Pragmatic Play and Hacksaw Gaming have got you interested, you can generally access them in most major online casinos and sweepstakes casinos. If you opt to play in a regular online casino you’ll be betting real cash, whereas in sweepstakes casinos you bet virtual ‘Sweeps Coins’ which can then be exchanged for prizes. Ultimately, it’s down to player preferences.
Slots are a huge hit inside today’s online casinos, which is why most game libraries are stacked with thousands of them.
These games mostly come from the slot providers broken down in this guide, along with several other major players in the industry.
Every slot provider, from Play’n GO to Hacksaw Gaming, has something unique to offer, so it’s always a great idea to experiment with different slots to find which ones you like the most.
Pragmatic Play has ultra-fun and colorful slots designed to keep you glued to your device, while Microgaming has big jackpot titles designed for the prize-chasers — each one is different.
Remember to spin responsibly, play with a budget, and always test the demo versions of these slots first before playing for real money.
