How we Rate Slot Sites
With over 30 years of combined industry experience, the team here at Online-Slot.co.uk live and breathe online slot games. Any slot site we list here has gone through a rigorous process whereby we register, deposit and play the slots on offer. Then we look at important aspects like bonuses and promotions, payment methods available, cashout times, customer support and reputation. Let’s dig a little deeper into what goes into our slots sites reviews:
|Play ‘n GO||Playtech|
|Big Time Gaming||IGT|
Whilst not all online slot sites have games from all the providers mentioned, a good mix of providers will give you a wide choice of slots to play. Some of the best slot sites do have most providers covered. The likes of Videoslots Casino and SlotsMillion Casino focus on slots and have over 3,000 and 2,000 slots respectively.
A good sign of a top slot site is one that has the best slots – i.e. the most popular titles. We look for the likes of:
|Starburst, Gonzo’s Quest + Dead or Alive II||NetEnt|
|Book of Dead + Wild Blood 2||Play ‘n GO|
|Immortal Romance + Thunderstruck II||Microgaming|
|Age of the Gods + Buffalo Blitz||Playtech|
|Bonanza Megaways + Star Clusters Megaclusters||Big Time Gaming|
|Book of Ra Deluxe + Lord of the Ocean||Novomatic|
|Cleopatra + Da Vinci Diamonds||IGT|
|Zeus + Black Knight II||WMS|
Another indicator of the better slot sites is how many new slots they have. New titles are released almost daily with over 100 new games available every single month. The best slots sites will offer new games as soon as they are available.
Some slot sites even release slots exclusively early. The likes of Mr Green, LeoVegas, bgo, Paddy Power and Rizk frequently have slots not available anywhere else (for a limited period).
Finally, have a good section of jackpot slots is also important to many players. Whilst they are different types of jackpot slot games, some offer life-changing jackpots. We look for the likes of Mega Moolah, Mega Fortune and Hall of Gods which offer jackpots that can reach 7 or even 8 figures. For more on progressive jackpot games, check out our list of jackpot slots.
Bonuses + Promotions
Everyone wants slot sites with a bonus. The best slots casinos sites will offer a slots-focused bonus. Most slot games contribute 100% to the wagering requirements so they are the best games to play when claiming a slots bonus.
Many top slot sites also offer free spins on slot games. You can get no deposit free spins or free spins upon your first deposit. The better slots-focused casinos will have offers on the most popular slots like Starburst and Book of Dead. Most free spins offers are valid on NetEnt, Play ‘n GO or Microgaming slot games.
It’s not just slot site’s welcome bonus that matters. Ongoing promotions and offers are equally if not more important to players. We look for good slot sites that have a range of incentives for slots players that include:
- Free spins on new releases
- Free spins on a certain range of slot provider games
- Leaderboard prizes for playing certain slots
- Random cash prizes + drops
- Slot Tournaments with free spins + cash prizes to be won
If you’re a loyal customer at a slot site, they can drop you free spins to try out the latest release or a top slot game every so often. Having promotions and incentives aimed at slot games is a great indication of how good a slot site actually is.
A growing trend are slot tournaments. Players compete against each other for the chance to win prizes such as cash bonuses or free spins. Normally, you have to play a slot game or from a selection of slots. The players who wager the most or achieve the biggest win multipliers will win a share of the prizes. Some slot sites run tournaments every 15 minutes or hour. As with all promotions and offers, please check the Terms & Conditions prior to claiming.
Payment Methods + Withdrawal Times
Playing slots is what you want to do but being able to deposit and withdraw is a crucial part in doing that. Whilst most slot sites will offer debit card deposits, having a range of payment methods is important to many. Make sure a site has the most popular payment options such as:
The best slots sites will also have newer payment methods like MuchBetter, Apple Pay and Boku which are aimed at mobile slots players. You should also consider the minimum deposit amount with £10 the average. Make sure deposits are free and have no charges.
Whilst it may be easy to deposit, a sign of a good slot site is how quickly they process withdrawal requests. The better ones will process within a matter of hours or even minutes. On average, expect e-wallet cashouts to hit your account within 24 hours. As for debit cards and bank transfers, between 1 and 3 days is the average.
Some of the better slots casinos offer facilities such as lock withdrawal features. This allows the player to lock in their cashout request so they cannot reverse it and play with their winnings. It guarantees their receive their winnings no matter what. The likes of SlotsMillion Casino and Risk Casino have this option available.
Finally, you need to consider fees for both depositing and withdrawing. On the whole, depositing is normally free. Some withdrawals can come with smalls, albeit small. The best slots sites will process your withdrawals quickly and for free. Make sure to read the fine print when requesting a cashout.
Being able to contact a slot site’s support team is an important factor sometimes overlooked. You may need to query a promotion or might need help withdrawing your winnings. Having a reliable customer service team in place is crucial to a site’s reliability and success.
Whilst picking up the phone nowadays has by and large become redundant, there should be a number of ways you can get in touch if you have any questions, queries or issues. The best slot sites offer various ways you can get help including:
|Live Chat||The quickest way to contact support|
|Telephone||A UK freephone number is ideal|
|Online Services||WhatsApp + Skype are popular these days|
|Having an email address is a must|
|Social Media||Active Facebook + Twitter accounts helps|
|FAQs||Extensive help section on website can help cover most queries|
|Callback||Some sites offer to call you back at a time convenient for you|
Whilst most slot sites will offer most of their contact methods, the Live Chat function has become the most way to communicating with a support team. Everything is written down in black and white with some sites sending you a transcript of your interaction with them via email. This allows for your documentation to be documented if you wish. With Live Chat, you can send attachments (like copies of ID), send voice notes and even make calls.
Whilst having all these ways to interact with a slots casino’s support team is great, response times are equally if not more important. You don’t want to be waiting for hours to hear back regarding a small query. The best slot sites will be with you in a few minutes at most, even during peak hours.
Track Record with the UKGC
First and foremost, slot sites in the UK need to be licensed and regulated by the Gambling Commission. They are also known as the UKGC. They were set up under the Gambling Act 2005 to regulate commercial gambling in the UK. They ensure licensees follow the License Conditions and Codes of Practice.
If a slots site doesn’t follow their rules and regulations, the UKGC will take action which can include fines and a license suspension. Their aims include:
- Prevent gambling from being a source of crime or disorder
- Ensure that gambling is fair and transparent
- Protect children and vulnerable persons from harm or exploitation
All slot sites listed here are licensed by the Gambling Commission and have a fully operational trading license. We also look at the companies behind the sites to ensure you safety and protection. Whilst many new sites popup all the time, we like to know where we play our favourite slot games and if it’s safe to do so.
We keep on top of industry news to ensure we only recommend the best slots sites. If we take a look at Rizk Casino for example, it’s part of the Gaming Innovation Group. They also run Guts Casino which tells us they are trustworthy and reputable.
