Best Slots Sites – Top Websites For Slots

Video slot games are the mainstay of nearly all international online casino sites today. With literally thousands available, and more being launched every month, you’ve probably seen them on casino homepages many times.

Video slots also offer some of the biggest jackpot prizes in the world, outside of state lottery services.

Progressive jackpot games, like Microgaming’s Mega Moolah or NetEnt’s Divine Fortune and Hall of Gods, give you the chance to play for multimillion-dollar prizes, with stakes as low as $0.20.

The Best Slots Sites

In general, a superior slot site should be a reflection of an outstanding online casino. Below you have a list of the top 10 best slot sites casinos.

You should expect these sites to have:

  • Complete safety and security, with appropriate licenses
  • Upward of 500 slot games
  • Lots of fast and efficient banking methods
  • Exemplary customer service

You’ll also want to see the best of the diversity that slots developers can provide, from the latest big-budget licensed titles to old-school classic three-reel games and mega jackpots. If you have a keen historical, cultural, or geographic interest of any kind, the best sites should feature at least a few slot titles to suit your preferences.

How We Pick the Best Slot Sites


Security and Licensing

No matter how many slots, bonuses, bells, and whistles a casino has, if they’re not a safe and respected operator then we won’t recommend you play there. It’s as simple as that.

We check a casino owner’s history, licenses, and third-party reputation, as well as their security protocols, so you can be assured your funds and data are securely protected.



Imagine winning a slots jackpot of thousands of dollars, and not being able to get it into your bank without a hassle. We help you avoid situations like that.

At the end of the day, the best slots collection in the world doesn’t mean much if a casino’s banking system uses outdated or slow payment methods and takes days (or weeks) to process.

We’ll help you discover the greatest online casino banking systems there are, so you can start enjoying your winnings as soon as possible.


Slots Collection

Because selection is one of the most important factors for slots fans,  any casino we recommend will have at least 500 games, and some may have well over 1000.

These should cross several dozen developers, including the top-tier Microgaming and NetEnt but also others such as PlayTech, Red Tiger, Yggdrasil, Scientific Games, Play’n Go, and many more.

The best sites will have a significant range of popular games, licensed tie-in titles, jackpots, and more niche-themed games, as well as old-school slots with three reels, blazing hot 7s, cherries, and the like.


Slots Sites Bonuses

The very best sites will give you a no-deposit bonus, often in free spins. If not, you should expect at least 10 or 20 spins for every $10 (or your local currency equivalent) you deposit, as well as bonus cash.

Be sure to read our expert reviews carefully, to check for those casinos with the most favorable bonus terms.



Of all online casino games, slots are most perfectly suited to mobile play. We know many of you want to spin the reels on-the-go, and any site we recommend will fulfill that need.

Compatibility also covers tablet play as well as various desktop browsers and add-ons, such as Flash. This is becoming a less common problem as things become standard across the Net, but you do still find such issues occasionally.

The Top Slot Providers


Microgaming is one of the oldest online slots developers in the business. They were one of the first companies making online casino software in the late 90s, and today they’re among the best-known developers worldwide.

Among their hundreds of slot games, you’ll find licensed titles from the latest pop culture smashes including Game of Thrones, Jurassic World, Playboy, and many more. 

You might also be familiar with the iconic Mega Moolah series—the record-breaking jackpot game that handed out the world’s biggest-ever online casino win in 2015, of €17,879,645.12, or just over below $20,000,000.

Oh, and that life-changing winning bet was just €0.25—or about 33 U.S. cents.


This Swedish developer was also founded in the late 90s, although the family operation has a history in land-based casinos going back 50 years before that.

Today they offer a broad range of online casino services but are mostly known for their extremely high-quality slots titles. These include some of the most popular games in the whole online world, such as Gonzo’s Quest and Starburst, or the jackpot games Hall of Gods, Divine Fortune, and Mega Fortune.

NetEnt games are among some of the most innovative and interesting titles on the market, offering you fantastic graphics and unique bonus-round mechanics by the bucketload.

You might also see NetEnt live-casino games quite often as well, an area in which they’ve been expanding their interests in recent years. 


The youngest of the three main slots providers, having started up in 1999, this Israeli company is, nevertheless, just as respected in the online casino world.

PlayTech’s slots are developed across no less than nine other developers from all over the world with whom they have merged, bringing you a different feel and design with each and every title. They also tend to bid for the biggest popular licensed titles, such as The Matrix, The Dark Knight, Justice League, and Gladiator.

Their main progressive jackpot game is the Age of Gods series. Still, with a highest-ever win just short of $1 million, it doesn’t quite reach the incredible levels of Microgaming’s or NetEnt’s jackpots. 

PlayTech is also well known for its RNG casino table games, like blackjack and roulette, and is one of the world’s foremost developers of such titles. 

Slots Bonuses

If you’re a slots player and you like bonuses, you’re in luck. That’s because slots are, by far, the most popular game for online casino promotions.

You’ll find free spins bonuses at almost every site, but they may not always be available on your favorite games.

Nevertheless, the best free spins offers will have:

  • Reasonable wagering requirements of 20-30x or less
  • No maximum win clauses
  • At least 10, and up to maybe 50 or more spins

Best Free Spins Offers

You’ll nearly always be able to use deposit-match bonus cash on slot games as well, except for in the rare cases when they are specifically designated for table games or the live casino. If so, the bonus offer will be clearly marked as such.

Keep checking our reviews every so often, as we’ll keep you updated with the latest and best offers—and you might just find a sweet no-deposit free spins deal with brilliant terms to go with it. 

Playing Slots on Mobile

Slots developers and casinos know that more and more of you want mobile play each year. For that reason, on-the-go casino experiences have improved a lot over recent years.

Whether you’re on the latest large-screen tablet or a small-screen budget smartphone, 90% of slots should work well on your device—if you’ve got a strong enough connection, of course. 

Aside from the game itself, the rest is up the individual casinos. We’ll take a good look at each site’s mobile version and let you know exactly how it holds up compared to the standard. 

Everything should be simple and easy to use on a small touchscreen, with responsive icons and intuitive menu design. Top-tier slot sites will even have their own dedicated mobile applications for Android and iOS, and our reviews will point them out too.

What are slots?

Slots are the most popular casino game of the modern-day. They are so-called because physical casino players bet by putting coins in the ‘slots’ to start the reels spinning.

Online, video slots are some of the most big-budget and graphically impressive casino games you can play—with some of the biggest jackpot prizes too.

Are slots fair?

99% of slots available online today have to submit to some kind of third-party independent verification from organizations such as E-Cogra or Gaming Labs International.

With many jackpot slots, you can even track recent and past winners online yourself, and most games from the big developers have their Return-to-Player (or RTP) rates clearly published.

This online transparency is certain to increase the appeal of these well-known and fast-paced games.

Can I play slots with a no-deposit bonus?

100%, yes. No-deposit bonuses might be more scarce than those requiring a deposit, but when you do find them, they’ll always be suitable for slots play, though not for all games.

Check out reviews, to find the best no-deposit casino promotions available.

What are the best slot games?

This is a highly subjective question. Some people prefer high RTP games like Mega Joker by NetEnt (99%) or PlayTech’s Ugga Bugga at 99.07%.

However, these kinds of slots often have less volatility, which usually means fewer bonus rounds and smaller jackpots.

Other players prefer big jackpots. If this is your preference, you might want to look at Microgaming’s Mega Moolah or NetEnt’s Mega Fortune, amongst others.

On the other hand, you might prefer themed games with recognizable characters and styles, such as Microgaming’s Game of Thrones, Playtech’s The Dark Knight, or Monty Python by IGT.

Lastly, there are some games that are just popular because they are very high-quality or have iconic themes. Just three of these are Microgaming’s Cleopatra and NetEnt’s Starburst and Gonzo’s Quest.
Of course, you could just go out there and try some completely different slots games until you find your new favorite.
