How to Find the Best Casino for Slots

Given how popular online slot machines are, you’d think finding a site that qualifies as the best casino for slots would be easy. It’s challenging precisely because slots are so widespread. Almost all gambling sites on the internet offer at least a modest collection of these games, but that does not automatically mean they are attention-worthy.

The best slots casinos online offer an array of benefits and perks to their customers. For starters, you can play games on instant play platforms or by downloading lobbies. Mobile casinos are also in demand, as spinning the reels on smaller screens anywhere you want appeals to the modern audience.

Payouts are an integral element of the entire experience, which means you have to consider payment options before you sign up and start playing slots for real money. There is also the question of bonuses, wagering requirements and contribution, licencing, and customer support.

We know this all could be a lot to take in at once, so we crafted this guide to help you out. Below you will find everything you need to know about finding the best casinos for online slots. We also threw in a list of our all-time favourites where you can enjoy a premium experience regardless of the game category you’re going for.

Main Aspects of the Best Casinos for Slots

To find a slot casino that you feel welcome and safe at, you must first ensure that it is a safe and welcoming spot to join. Ask yourself: is this casino offering everything that I want?

Well, sometimes it’s hard to know exactly what you are looking for because your gambling adventure may entail a host of other things you aren’t aware of. Luckily, you have experts who are here to point you in the right direction. When players are searching for a good online casino for slots, they have to consider the following factors:

  • Game selection
  • Bonus offers
  • Ease of access
  • Available payment methods
  • Licencing and reputation

Needless to say, each item on the list includes many other aspects that you have to have in mind. We’ll explain everything in detail below.

Game Selection

If players want to play slots, it makes no sense to sign up at an online casino that doesn’t offer many. Instead, players should ensure that the portfolio contains at least 500 slot machine games, preferably from multiple providers. Check the software too, and always go for acclaimed game-making companies.

Bonus Offers

We advise players to search for slot-specific bonuses. Most top-rated online casinos offer signup bonuses that are meant to be used only on slot machine games. No deposit casino bonuses, free spins, and deals with slot-friendly wagering contributions are great examples of deals you can take if you are into slots.

Ease of Access

Sign up at online casinos that make it easy for players to find their favourite slots games. Top-rated slots casinos offer search bars and various game filters to help players sort their slots according to popularity level, game provider, alphabetical order, game category, themes, and so on.

Available Payment Methods

To get money to and from your gambling account, you need a payment option. But you cannot pick just any, as not all are as reliable and efficient as you’d want them to be. The key is safety along with speed, as most punters aren’t too keen on waiting days for their money to appear in their bank accounts.

Licencing and Reputation

You can find a plethora of titles and promotions that promise a wonderful adventure, but who can guarantee that the adventure will be safe? The licencing authority, that’s who. Sites must be licenced by authorities like the UKGC or MGA; otherwise, there’s no say in what they can do to scam their customers and how dangerous they are. Licences guarantee that the venue is compliant with laws and protects its players.

10 Best Online Slots to Play at Casinos

No slot casino guide is good if you don’t know what to play. So besides searching for the top 10 casinos for slots, we also searched for the best gaming choices you can play for real money at these websites.

Here are the top 10 online casino slots to play at casinos online.

  1. Starburst – NetEnt (96.10% RTP)
  2. Book of Dead – Play’n GO (94.17% RTP)
  3. Reactoonz – Play’n GO (96.51% RTP)
  4. Hades Gigablox – Yggdrasil (96% RTP)
  5. Gonzo’s Quest – NetEnt (96% RTP)
  6. Absolootly Mad: Mega Moolah – Microgaming (92.02% RTP)
  7. Lucky Neko Gigablox – Yggdrasil (96.40% RTP)
  8. Aloha! Christmas – NetEnt (96% RTP)
  9. Slot Vegas Megaquads – Big Time Gaming (96.56% RTP)
  10. Bonanza – Big Time Gaming (96% RTP)

You might recognise most of these games because they are common on most ‘Featured Games’ lists. Indeed, most gambling websites we present here display these games right at the lobby’s entrance because most punters go right for them.

Another thing you might’ve noticed is the diversity, both in terms of RTP and themes. Moreover, they are not all standard video slots, as the list includes progressive jackpots, Megaways games, and Yggdrasil’s special slot mechanics embedded into Hades and Lucky Neko. This means you get to play with thousands of winning ways, which certainly adds spice to the overall experience.

These games are here at Best Casinos too! You can play free casino slot games for fun right here. Just visit our free play section and enjoy these 10 best online slots, along with hundreds of other award-winning titles.

Top Slot Casino Bonuses

Like we already mentioned, slot-oriented bonuses are a thing, and there’s no reason to miss an opportunity to enhance your casino slot experience.

With the following offers, every day can be a great day for playing slots for real money.

Slot Bonus Offer

Slot Casino

Playthrough

61 Free Spins on Slot of the Month King Billy 30x
10 Free Spins No Deposit Bonus Guts None
50 Free Spins on Slot of the Month VipSlots 40x
100% Low Playthrough Bonus Uptown Aces 15x
£10 No Deposit Bonus 32Red 50x

 

The listed offers include both free cash and free spins. Free Spins are the most common version of a slot bonus because they allow punters free spinning on their favourite slots. Alternatively, you can also try no deposit bonuses as they include free cash that you can spend on any game without any restrictions.

Reliable Payment Options for Slot Casino Players

If you are worried your money will take longer to transfer to/from your account, you need to find a reliable payment method. But which one is reliable? And how can we know that it will transfer the money safely?

Our best advice is to follow what other punters are doing. Nowadays, the banking world offers various efficient payment services, and your options are virtually limitless. From mobile banking services that you can use straight from your smartphone to infallible credit cards, the choice is all yours.

Here are 3 most popular payment options that players use at online slot casinos.

Visa is a credit card option available worldwide. The benefit of sticking with Visa is that you can use it at nearly every gambling website on the internet. However, speed is a downside, as Visa withdrawals take days to complete. If you want something a bit faster, we suggest going with AstroPay and MuchBetter, as they both cash out in less than a day.

AstroPay is a virtual prepaid card that you can use for safe deposits and withdrawals. It’s available at most new gaming sites, especially those that work in Latin America. If you can get over the lack of currencies, you’ll surely enjoy transferring money with AstroPay. If not, you can check out MuchBetter.

MuchBetter is a UK e-wallet that accepts deposits and withdrawals. Highly flexible, cost-efficient, and fast, MuchBetter gives its customers a tailored experience no matter where in the world they currently are. A drawback is the MuchBetter Mastercard restriction in Europe, which leaves Europeans without this delightful perk.

The Best Casino Sites for Slots 2021

The top 10 casino sites for slots list that you saw above includes the all-time favourites for slot gaming. They are all established names with decades of experience and hard work. With impeccable reputations, fair gaming conditions, and strict licencing regulations, they cannot afford to be anything less than perfect.

But what about newer sites? Players often get tired of big brands and want something new or exotic to try. And can new casinos offer the same kind of experience as the biggest online casinos in the world?

The answer is yes; they can. Smaller sites that haven’t been live for long can still have a respectable offer that’s more than worthy of your energy and time.

The table below includes our top 2021 picks that you can think of as an extension of the list above. Here are our top slot casino picks for 2021.

Best Slots Casinos for 2021

Casino Name

Welcome Offer

1 Mason Slots 100% up to €200 + FS Click Here
2 Bitcasino.io None Click Here
3 Woo 300 AUD + 200 FS Click Here
4 GreenSpin.bet 125% up to 0.01 BTC+ 100 FS Click Here
5 Slotum 100% up to $/€100 + 100 FS Click Here

 

Why did we choose these sites exactly? We chose them because they passed every single test of ours with flying colours. They have spectacular offers, thousands of titles in the library, and drool-worthy bonuses every player would want to claim.

But best of all, each is unique and offers something you cannot find anywhere else. For starters, Mason Slots takes a playful stance on the theme of masonry. It’s fun if you are into mysterious societies and cultish roleplay.

Bitcasino.io, along with most of these websites, is a Bitcoin casino. The site is one of the first BTC sites that came into existence and is going strong after years of catering to BTC players. It does not offer a welcome pack because you have a plethora of other deals to claim when you become a new member.

Woo is a world-class gambling website, but one that’s among the most popular ones in Australia. Australians love their pokies, and the fact that they choose Woo time after time speaks volumes about the operator’s exclusive offer.

When it comes to GreenSpin.bet and Slotum, the only thing we can say is – daily promotions and delicious bonuses. This is especially true for GreenSpin, where you get a bonanza of green deals that you can claim every single day.

Frequently Asked Questions
What are the most popular slots?

The popularity of individual games depends on the market in question. For instance, UK players love Gonzo’s Quest and Book of Dead, while US players always pick Frankenstein Monster and Bonanza Megaways. You can visit our top 20 online slots list and see the most popular slots online.

What slots can you win real money?

Any slot game can bring you real money wins if you play with real cash. Visit any casino and pick a slot that you like from the lobby. When you start playing the game, wager real money, and if you win, you will win real money. If you pick demo/free play, you will not win real money.

What percentage do slots pay out?

Payout percentages vary from slot to slot, but in general, the RTP (Return to Player) should not drop below 95%. The highest it can go with slots is 98%, and slots do not tend to offer higher payouts than that. Hence, the standard theoretical RTP rate for slots is 95%-98%. The industry average is 96.20%.

What casino has the best slot payouts?

Videoslots is hands down the best online casino for slots. Players love visiting Videoslots not only because it has the biggest collection of slots in the world but also because it offers fair and fast payouts and gives fairly good payouts to all its players.

What is the best online slots casino?

In terms of content and the quality of service, Videoslots is one of the best casinos to visit for slots. If you live in a country not accepted by Videoslots, you can explore crypto casinos known as sites that offer the most content and fairest conditions. They are also quite safe because they provide anonymous crypto transactions, so your personal info stays protected always.

Are online slots legit?

Yes, online slots are 100% legit. Companies producing slots have to go through numerous tests and checks before they release a game. Moreover, they have to comply with countless rules and laws from gambling authorities if they want to retain their working licences. Therefore, they use RNG (Random Number Generator) to ensure all number and symbol combinations are unpredictable and impenetrable.

What is the best online casino for slots in the UK?

The best online casino to visit and play slots in the UK is PlayOJO. This remarkable venue is one of the safest online casinos in the UK, and the UK is very strict when it comes to gambling regulation.

Do casino apps pay real money?

Yes, casino apps pay real money because they are the same as playing casino games via PC or mobile browser. The only difference casino apps have is that you can download the app and access the games faster. Other than that, everything is the same – you can both win real money, play any casino game, and even claim exclusive casino app bonus offers.

How do online slots work?

Online slots use RNG (random number generators) to produce infallibly random number sequences. By pressing the Spin button, a player triggers the game code that uses RNG algorithms to generate a random sequence. That sequence is seen on the screen as a reel full of symbols. If you happen to land three or more identical symbols in a specific order (the provider sets paying sequences or paylines), you will get a payout.

What is a slot casino?

A slot casino is an operator with a special offer of the best online slots for its customers. Moreover, top slots casinos offer slot-focused deals and promotions and payment options that suit slot players.

What is the best online casino for slots?

The best online casino for slot machines is a site that honours the players by giving them enough content variety and safe playing conditions. Low wagering requirements, big bonuses, and transparent terms and conditions are necessary for a site named the best casino for slots.
