Finding a slot site won't take much, they're literally all over the internet. Picking out the ones that count though, now that can be time-consuming, or it could have been. Luckily you have us and we've gone in all guns blazing with a list of the best slot sites the market has to offer. We aren't saying that these are the only online casinos that you can trust. Of course, there are others out there. Then again, these are the ones we're willing to take a gamble on and we have the casino reviews to prove it.

New Slot Sites are the Hidden Gems

Experience isn't always a good thing. There are some veterans who are still at the top of their game but they're competing against the new kids on the block. The thing about being an old-timer is that there's a risk of complacency. That's where new slot sites could be a good alternative. They're looking to prove themselves, of course, they're going to try and offer a better deal. 

More often than not, their welcome bonuses will be enough to reel you in. Would we take a chance on a new brand slot site? Considering what's out there, we'd be hard-pushed not to. Some of them are already up there with the big guns in iGaming. It just takes knowing what to look for. For what it's worth, we've listed a few ourselves.

Which are the Best Slot Sites Though?

Our top 7 slot sites should get you off to a good start but even that's quite a lot to choose from. We'll cut you some slack and narrow it down even further. Here's our pick of the best 3 online casinos. When it comes to online slots, they don't just deliver, they go above and beyond.

888 Slots A.K.A. The Hybrid

You can talk about online slot sites and not 888. That's mainly down to their proprietary software. If you're looking to play 888 originals, this is the only place to get them. That and a few other sister sites like 777 Casino. How do they compare to other top game developers like NetEnt? Well, they don't have to because the casino hasn't just stuck to their in-house online slots. They've looked to collaborate with other big names like Red Tiger and Yggdrassil.

Perhaps the only thing missing here are the record-breaking progressive jackpots Mega Fortune and Mega Moolah. They actually don't offer Microgaming slots. Then again with enough of their own 888 exclusive casinos, we're willing to close an eye. Their welcome bonus is also pretty appealing. As far as online slot sites go, these guys mean business.

William Hill Slot Site - Beyond Betting

We didn't think we'd ever see the name William Hill on a slots focused page. Then again, probably neither did he. What started off as a bookmaker is now also a successful online casino. Needless to say, they've come a long way. The actual casino is similar to a lot of other Playtech sites available online. They haven't stopped there though but looked to diversify their casino games rather. Blueprint, Novomatic, IGT; take your pick. There's also a Macau section specifically for players who like these Asian themed slot games.

The thing we like most about William Hill slots though is their approach to bonuses. Their welcome bonus is decent but what will really get you fired up are the rest of their promotions. Free spins, deposit bonuses, cashback; the slot site looks to give something away almost every day. With so much to choose from, you'll need every little boost that you can get. How else are you going to get through such a wide array of slot games!

Betfair Casino - Nothing Like a Good Old Playtech Site!

William Hill isn't the only betting site that knows their way around slots. There's Betfair too and they're also big on Playtech. Similarly, the slot site has looked to extend their product by adding in a long list of other game providers. Multiple slots sections with several game filters in each, the choice is that massive!

That's not even the best part, especially for UK slots players. They tend to have some special bonuses just for this niche. That's not to say that there are no bonuses for players from the rest of the world but the UK ones are that bit better.

What Sets Good Slots Apart from the Rest?

We've given you a list of some of the best slot sites around but don't take our word for it, do your own research. There are certain qualities to look out for. A valid casino license is always the best place to start. It's something that most gamblers do look out for. Here's some of the more important stuff that tends to get overlooked.

Keep Your Eyes Peeled for Game Filters

A casino lobby may have the choice we're after but no one likes scrolling through endless lists. Quite frankly we'd take an online slots site with a smaller game choice over a massive one with navigation issues any day. That's where game filters come in. Most games lobbies have them in, in some form or another. The most basic ones just group games according to game type. When slot games are in the 100s, even 1000s, that's nowhere near enough.

The best slot sites will look to narrow things down even further with subsections within each game category. Slots come in all shapes and sizes, we'll talk about this in more detail later on. In the meantime, here's a list of how these games can be filtered at some of the better online casino lobbies.

  • Type of slot game
  • Slot volatility
  • Return to player
  • Game provider
  • Features
  • New slots
  • Theme

Chances are that you won't find one online casino with all of the above filters. Most of the good ones will, however, have enough options to help you browse at ease. A user-friendly slot site is always at the top of our list.

Slot Sites and Bonuses - The Perfect Match

Even if we don't always admit it, everyone loves a casino bonus. The good thing about slots though is that they tend to contribute fully to wagering requirements. They aren't the only casino game, scratchcard are another. Table games, on the other hand, aren't so lucky.

Welcome offers, cashback, reload bonuses; there are so many out there. That doesn't necessarily mean that you should snap up any offer that comes your way, just because you can. This is why we always do our research on slot sites bonuses. Whether it's free spins or a deposit bonus, always read the print. Sometimes its a mix of the two, which is definitely the most flexible option. Just remember to look out for other things like minimum deposit limits, maximum winnings and wagering requirements. The last thing you want is to get caught out.

Quality Payment Portfolio

Banking is something that a lot of players fail to observe, especially new customers. It's actually one of the first things we look at on slot sites. Transparency, for starters, says a lot about the online casino. Then there are the specific payment methods on display. We aren't talking about the regular suspects like Visa and MasterCard or e-wallets Neteller and Skrill. We'd assume that most casino sites cater for this. The thing we really look for are country-specific methods.

Take UK slot sites, for instance, there's a reason all of the top-rated ones are PayPal approved. Boku Pay is another example of a payment option tailored specifically to this market. This comes as a result of the surge in the demand for mobile casinos but we'll take a closer look at this in the next section. 

Mobile Slot Sites are a Necessity

In a world where literally everything is going portable, it was only a matter of time before mobile slot sits came about. Literally, every casino out there is mobile-friendly but some are better than others. Opt for instant-play or download a casino app; some give this option, the choice is yours. Just make sure that the platform has in fact been fully optimised. Tick that box and take your favourite slot games literally anywhere.

Ironically, this is often where new slot sites come out on top. Well of course they do, they were born in the age of mobile gambling, they didn't have to adapt to it. For what it's worth, the best ones will ensure that their app is almost an exact replica of their desktop site. At times they're even better; you've heard of mobile-first slot sites, right?

The online casinos aren't the only thing to consider. That's only half of the story, mobile slots are the other half. A mobile-friendly interface won't get you very far if there aren't any games to play. The good news is that software providers caught on pretty fast. New or not, nowadays, most mobile slot sites have a well-sized games lobby.

Online Slots & Safety - What They Didn't Teach You in School

Safety was bound to come up at some point. This is online gambling after all; doubts are expected. There were cracks in the past but the industry has tightened things up a lot over the years. This is particularly so for UK players. All slot sites targetting this jurisdiction must be licensed by the UKGC.

For some, it may just be a license but in the world of iGaming, this is the cream of the crop in regulatory bodies. Slot sites must abide by a strict set of criteria. The same goes for software providers looking to make their slot games available to UK players.

This is why any of the online casinos that mean the real deal will have some form of seal from a third-party auditor like eCogra. The better slot sites will also look to make the game details fully transparent. Some will even provider payout reports with all of the relevant RTP values. There's no cutting corners with the UK Gambling Commission.

Always Read the Fine Print At Slot Sites!

A word of advice when it comes to slot sites, always check back to the full terms. New or not, most will make this information easy to access. We aren't just talking about new players looking to pick up a welcome bonus. Even then though, the bonus terms are important to check back to. Not all online slots contribute fully to wagering requirements for instance.

That's just the tip of the iceberg though. Other things to keep in mind are minimum deposit limits, maximum bet per spin and more importantly the policy on progressive jackpots. The last thing you want is to hit a win only to find issues when trying to cash out.

The fine print counts, although when it comes to the best online slot sites, it's not that fine at all!
