Our Methodology

At AhoyGaming we evaluate gambling sites according to a fixed set of objective criteria. These criteria mirror our thinking about the most important facts and features of any casino or gambling site. We evaluate every site we encounter according to this strict list.

Our formal evaluation methodology ensures that gamblers can learn which sites are the most fun, the most trustworthy, and the most secure from our reviews. And it ensures that all of the reviews we publish are apples-to-apples comparisons. It’s a bit of rigor in a web ecosystem that frankly lacks rigor. Our approach lets us stand tall in the industry and face ourselves in the mirror in the morning.

Each website on our list represents one of the best slots sites on the internet. We have subjected each of them to our exacting six-point evaluation program:

User Experience

Our first category refers to the visual and technical sides of the website and how players interact with it. An appealing design makes a site more effective at luring players in, while an effective organization plan makes playing simpler and more enjoyable.

The quality of the online casino experience depends on the ease of navigation of a slot website, plus the quality of the graphics, the smoothness of the gameplay, the alacrity of game loading times, and the personalisation and customisation options for players.

Another feature that affects the score: compatibility of the site and its games with multiple platforms, including mobile devices.

Game Variety

Among the most important factors is the variety of slot games at the website. We ensure that each casino that makes our list has a varied selection of slot offers, slot types, and slot themes.

Old-fashioned real-world slot machines were once limited to three reels. Online games can have five, seven, nine, and even 12 reels. This not only increases the number of paylines and the variety of winning combinations, but also comes with bonus rounds and hidden levels of play.

The best slot sites offer highly interactive 3D slots with fantastic graphics and sound effects that immerse players in the action and enhance the gambling experience. Some 3D games require a software download, while others can be played directly from a browser.

Finally, we look for progressive jackpot games. The exciting part of these slots is that the jackpot builds and builds over time, and the jackpot can be won from any designated slot machine. Whoever matches a specific payline wins the progressive jackpot.

Welcome Bonus

The online slots bonus offered upon registration or the occasion of making a first deposit is quite often a decisive factor for players who are deciding whether or not to play at a particular site. It’s an important element of our review rubric as well.

A welcome bonus for new players can be a deposit bonus, free spins, or a combination of both.

Newcomers need to know how to get the best out of these extras. For example, some sites offer matching bonuses of various values for the first three or more deposits. You can use the free money to take higher risks in your betting – and maybe score bigger wins.

Then there are the free spins you get just for registering. Possible limits include using the slot bonus spins only on specific slots, a maximum stake, or bonus expiration times.

Wagering Requirements

Wagering requirements are conditions you must meet before withdrawing bonus funds. Every online gambling site has wagering requirements, and it is here – more than in bonus matching amounts – that sites most differ.

Let’s say you received a welcome bonus from one of the best slot sites listed in this review. The bonus is worth £10 and it has a 30x wagering requirement.

What does wagered 30 times mean? It means that the casino requires you to wager that £10 bonus 30 times – or place £300 worth of bets – before you can withdraw the money or any money that you won by wagering it.

Some wagering requirements have limits. For example, a site might require that you finish meeting the wagering requirements within 30 days or forfeit the bonus funds. Every slot bonus really ought to have its own page on the site’s policies page.

Players should focus on finding the smallest wagering requirement they can clear over the longest period of time.

Banking Options

Online payments have evolved tremendously. For those reasons, the best gambling houses offer a variety of payment options to meet the player’s payment preferences. Options for making deposits include debit cards, credit cards, e-wallets, bank transfers, pay-by-phone, and cryptocurrency.

At most sites, withdrawals can generally be made via the same channels. We take special care when evaluating withdrawal options because some sites make withdrawing your own money a complicated, slow process. At the best online slots sites, withdrawals are easy and fast.

When we think of banking, we naturally think of safety and security measures taken to keep our funds and our bank accounts safe. All of the sites we list here are regulated, which means government agencies periodically review security measures and technologies to ensure customer interests are protected.

Customer Support

Plenty of people like to play slots, and naturally enough, some of them encounter problems or have questions. That’s why our final evaluation criterion is reserved for customer support.

The best slot sites in the UK employ dedicated, reliable staff members to help players and answer their questions. We pay particular attention to the variety of customer support channels available – email, phone, chat, fax, and so on. We measure response times. We assess whether customer service agents are polite and whether they are sufficiently knowledgeable to help players with all the questions that might arise.

In addition, an easy to understand Help or FAQ page earns a site point. We are always sure to report details such as hours of operation, the presence or absence of toll-free telephone numbers, and so on.

william hill logo best poker sites

Constant promotion

Reputable casino

Hundreds of slot titles

William Hill was founded by bookmaker William Hill in 1934. Hill took bets via mail and telephone. William Hill’s online casino has been operating since 2000, and today it is one of the most widely recognised betting brands and UK slot sites around the world. The William Hill Sportsbook app passed a staggering two million downloads in 2018.

The William Hill platform is visually appealing. Both the website and the mobile app load quickly. Rules about the welcome bonus, wagering requirements, and bonus clearance time frame are clear and easy to understand. Although the site is still devoted primarily to bookmaking, it offers a solid catalogue of more than 700 slot games.

William Hill runs a lot of promotions. During our review period, the page of bonuses listed 16 active promotions, including two for new players. However, 15 of the 16 promotions are related to sports betting. The welcome bonus for UK players is a slots bonus of 10 free 10p spins on the William Hill Megaways slot.

All 10 spins must be used within 24 hours, otherwise they are forfeited along with any winnings you have earned with free spins. Funds you win through this promotion can be withdrawn immediately after the tenth spin as cash or wagered on the site in any way you like – there is no wagering requirement.

William Hill accepts debit cards, credit cards, and e-wallets like PayPal, Skrill, Neteller, WebMoney, Yandex.Money, QIWI, and ecoPayz. Credit cards and some e-wallet options are not available for UK slot sites customers due to the regulations of the UK Gambling Commission.

As for customer support, you’ll find a comprehensive Help and FAQs page. The Contact Us page lists chat, email, and phone as support channels. A notice on the site says that due to the coronavirus pandemic, the support staff is currently unable to provide phone support.

casumo logo best slot sites

Award-winning platform

More than 2,000 slots

Live chat customer support

Casumo is an award-winning online casino founded in 2012. Among its recent awards is the International Gaming Awards Best Online Casino Operator trophy for 2019.

The design is modern and appealing, and the website is fast and easy to navigate. Players can find updates on the latest game releases and betting news in the casino’s blog. Amazingly, there are more than 2,000 slots and games available. Casumo picks the games from the best game developers and launches new ones every week.

New players receive 30 free spins on the Book of Dead slot game. In addition, they get a 100% match bonus up to £300 on their first deposit. The deposit bonus must be wagered 30 times before funds can be withdrawn.

Slot players can deposit money using Visa, Mastercard, Skrill, Neteller, Paysafecard, MuchBetter, or mobile billing.

777 casino logo best slot sites

Over 800 slot titles

Numerous payment options

Fantastic design

777 Casino is part of Gibraltar’s 888 UK Ltd, whose online slots and gaming operations are licensed by the UK Gambling Commission. Players from the UK, Germany, Austria, Canada, and Ireland can play freely on the platform.

The website is fantastically appealing to anyone who enjoys a vintage design mimicking retro Vegas casinos. Performance wasn’t quite as thrilling: The website felt a bit laggy when we were scrolling through the slots.

The casino offers more than 800 virtual slot machines. Players can explore the games using a handy filter option and select Jackpots, Classic Slots, Low Volatility, High Volatility, or In-House slots.

The online slots bonus for new players consists of a matching bonus of 100% of your first deposit up to £200. New players can also claim 77 free spins by responding to a verification email within 48 hours. That’s the good news. The bad news: This online casino has a 50x wagering requirement for withdrawing bonus funds.

Additionally, players new to 777 should note a couple of things when it comes to deposits and withdrawals.

Deposit channels that can also receive withdrawals include Visa, Mastercard, ecoPayz, iDebit, MuchBetter, Neteller, PayPal, QIWI Wallet, Rapid Transfer, Skrill, Trustly, WebMoney, Interac e-Transfer, and wire transfer.

Deposit methods that can’t receive withdrawals are Apple Pay, AstroPay Card, Bitcoin by Skrill, Instadebit, Instant Payments by Citadel, Interac Online, QR Code, Nordea, online bank transfer, Op-Pohjola, Oxxo, Paysafecard, PurplePay, Sofort, Todito Cash, Transferencia Bancaria, Boleto Bancario, Verkkopankki, and Yandex.Money.

The FAQ and Support pages of this slot website are a bit confusing. Some parts contain large blocks of text that, in our opinion, should be organised better so users can find information more easily.

If you can’t find what you’re looking for in the online guides, you can reach out to 777 customer-support agents any time via email or telephone.

What is the most popular slot machine?

The progressive jackpot game Mega Moolah seems to be getting the most attention from players across the world. It’s a five-reel slot with 25 pay lines, and the jackpot amount, which often exceeds €1 million, makes it one of the best slots to play.

Yes, they do. The amount depends on factors that differ from casino to casino.

Jackpots, especially progressive jackpots, can represent climb to life-changing heights. At many sites, the Mega Moolah progressive jackpot quite often climbs higher than €1 million.

What are the odds of winning on online slots?

The odds are directly connected with the type of slots you’re playing and the number of pay lines or winning combinations. You’ll win more often if you play more lines on slots with more reels.

Is there a way to tell if a slot machine is going to hit?

No. The best you can do is to check the slot’s Return To Player rate, which is the percentage of the initial stakes a player can expect to receive as winnings over a large number of spins.
