The lack of advanced search options can be considered a disadvantage, but you can use the search tool to filter games based on their titles and try them out in demo mode before you wager real money.

Our Take

Pros

  • This gaming library is composed of more than 1900 options, whereas most casinos stick to between 500 and 1000
  • Influential providers back the games up, such as Microgaming, NetEnt, and Playtech

Pros:

  • Considering that the slots standard is 500, this casino has more than 1100 options available
  • The site features some of the most popular developers in the industry, such as NetEnt and Playtech

With our +7 years of experience in the UK online casino industry, both new and seasoned players can benefit from our experience-driven reviews.

Monopoly Casino: Best online slots UK site for 2023

Our experts’ decision to go with Monopoly Casino was influenced by its diversity when it comes to slots. If you play mostly jackpots, then this site is perfect for you because it has more than 40 different jackpot titles, and a sizeable variety of high-variance titles.

Why we chose Monopoly Casino

  • 20+ exclusive in-house slots;
  • No wagering slots bonuses;
  • Instant Apple Pay withdrawals;
  • Android and iOS slots apps.

Alternatives

Monopoly Casino might not be the best choice for players that are looking for a good slot site with a low deposit. This is why we recommend Rhino Casino, as it has a 5/5 star rating in games and the lowest minimum deposit of £1.

Megaways Casino: Runner-up slots casino

The choice of Megaways Casino was driven by the fact that it offers popular slots and providers, on top of the fact that the number of slots available is high. We didn’t rate it to the maximum because it slightly lacks diversity.

Alternatives

Players that are looking for jackpots in particular might not be interested in Megaways Casino as it offers progressive jackpots. For this category of players, we recommend Immortal Wins Casino, which offers more than 50 jackpot titles.

Hot Streak Casino: Top new slots online casino

Relying on our expertise in the industry, we selected Hot Streak Casino for our top new slot site because it is a good all round Casino that offers both diversity and a good number of slots. The platform is online since 2022 and we think that for a Casino this new to provide the high standard that it does is very rare.

Vbet Casino: Best for number of online slots

Vbet Casino stood out for us for its extremely large slot catalog. It contains more than 8000 different slots from more than 80 providers, which is why we rated it the best casino for the number of slots.

VoodooDreams Casino: Top Netent slots site

Our team of experts picked VoodooDreams Casino for its extended collection of +114 Netent games. In our opinion, the website offers a high number of slots and progressive jackpots that are provided by some of the most popular developers of the industry, which adds to diversity.

Grosvenor Casino: Best for Pragmatic Play slots

We went with Grosvenor Casino for its proven catalog of Pragmatic Play slots which is not only vast, it contains the most popular slots available from this provider. The casino offers more than 700 slots from 55 developers which is a great way to impress a gambling expert.

Pokerstars Casino: Top Microgaming slots site

Pokerstars Casino appealed to us because of its extended slot catalog that offers more than 70 Microgaming slots.

The games catalog is vast and there are 19 providers available which makes the user feel the diversity.

You Can Trust Our Best UK Slots Sites Picks

Our experienced gaming experts manually analysed each recommended slot site. Our reviewers followed our review criteria about bonus options, specific and general terms of use, responsible gaming, wagering requirements, banking, support, and gaming content.

Slots Casino Real Money Sites’ Security

We considered several variables to determine a slot site’s security other than licensing. For instance, a factor as simple as popularity and reputation can signify reliability.

If an operator has high and positive ratings across several reliable online review platforms and forums, you can take it as an indicator of trustworthiness.

Essential Third-party Game Testing Certificates

Many of our recommended UK slot sites have independent third-party organisations test and evaluate their gaming software to ensure its fairness and functionality. To ensure the gaming quality is tested, we seek approval from eCOGRA, iTech Labs, Gaming Laboratories International (GLI), and similar testing labs.

Slots Variety and Software Provider Trustiness

A wide range of slot games can make it harder to pick a single game but gives you more range and allows you to find a game tailored to your gaming style. We promote only UK slot sites that provide licensed content from industry-leading software providers with a proven track record.

We Test Online Slots Real Money Bonuses Ourselves

  • We examine the casino bonus offers and their wagering requirements
  • We sign up and claim the bonus with a qualifying deposit or code
  • We start wagering on qualifying games
  • Once all bonus terms are met, we submit a request for a withdrawal
  • Provide withdrawal verification documents (if necessary)
  • Wait for the casino to approve the withdrawal and credit the bonus/winnings

We Manually Check Payment Methods

Alongside reviewing the availability of payment methods, we check the efficacy of each payment option. A few of the banking criteria include deposit and withdrawal limits, processing of transactions, and whether the casino or payment service charges any fees. At the very least, a casino should have the following payment methods available to all UK players:

  • Visa
  • MasterCard
  • Boku
  • Skrill or Neteller
  • Pay by Phone
  • Bank Transfer
  • Neosurf
  • PayPal

We additionally create and curate lists for casinos with specific payments:

Keeping up to Date With the Latest Mobile Gambling Trends

We tasted several slot games in each of the three casinos using an iPhone 14 Pro Max and a Samsung s22, and the games worked exceptionally well, with no lags, crashes, or similar issues, on both devices. Of course, you can even have an older smartphone model and still enjoy optimal game performance.

Our experience has shown that the bulk of online casino players in the UK, and beyond, tend to play on mobile casinos. If you want to play new mobile slots on their release date, you should seek the newest mobile casino platforms.

A mobile app is not necessary, but it may appeal to many mobile players. At the very least, we ensure the slot site is compatible for use on mobile in-browser on all major operating systems: iOS, Windows, and Android. Only after we’ve manually tested a casino’s mobile functionality relating to gaming content, payments, support, security, and user experience do we decide to recommend it.

Online Casino Slots: Sign-up and Bonuses Guide

Below we provide a short player guide on how to navigate between UK slots sites, find the best bonus for your specific slot preferences, sign-up and claim it.

How to choose your best online slots sites to play

How to Choose Your Best Slot Sites to Play

  1. Choose a licensed operator
  2. Pick a casino with proper game filters
  3. Pick sites with high RTP slots
  4. Look for medium-to-high volatility slots
  5. Find a casino with slots from leading providers
  6. Check for slot-specific promotions, like free spins
  7. It’s preferable for the slots to have demo (fun) mode

How to compare online casino slots bonuses

  • Look for UK Slots Sites for No Deposit Free Spins: Use our filter to select sign-up slot bonus rounds with favourable terms.  Note, easy as the bonus terms may seem, you still have a limited amount of time (around 7 days, on average) to satisfy the remainder of the terms before the bonus expires.
  • Find Online Real Money Slots Sites with a Free Sign-up Bonus: A casino can award you with a slots no deposit bonus for your active play, if you are a VIP member, or immediately after you create an account. The former case is to be found in any of UK’s casinos with VIP and loyalty programs. You’ll notice each of the no deposit bonuses above are cash bonuses (as opposed to free spins). But specified slot games qualify for each bonus, meaning you can play first-rate slot games and take advantage of the games’ features while redeeming your bonus at the same time.
  • Choose UK Slot Sites With a Valuable Welcome Bonus: By value we mean welcome bonuses with fair terms and wagering requirements and acceptable withdrawal and betting limits. Each of the listed sign-up promos meets our criteria. For some offers, like the Barz Casino welcome bonus, the wager terms may seem slightly above average, though the bonus compensates with other favourable conditions.
  • Best Source of Online Slots No Wagering Bonuses: For a small deposit of just £10, you can claim a no-wager free spins bonus at many of our listed casino operators, but PlayOJO is renowned for being a no wagering casino all-around.

Regardless of the no-wager benefit, you still need to read the terms for each bonus to know which games qualify and satisfy the remaining conditions.

A Comprehensive List of Slot Sites for Top Bonuses

 

 

Should you play with online slots real money free spins?

With free spins for online slots, real money games can become a much better experience, because you have the opportunity to test the online real money slots sites yourself before depositing.

If you choose from our selection of slots no deposit bonus offers, you are ensured to play on secure slot sites with free bonuses on sign-up and explore various slot games by top providers.

Despite an offer can theoretically result in a real money payout, the fact that it doesn’t require a deposit generates a low expectation due to the equally low value of the spins bonus itself. Still, no wagering slots bonuses give you a high chance of generating an early positive bankroll.

Reels

Vertical alignment of symbols that spin in slots.

Rows

Horizontal alignment of the spinning slot symbols.

Paylines

The patterns in which symbols match on the reels to form winning combinations, as encoded by the supplier.

Gamble/double feature

The option to trigger a mini-game within the slot machine and risk your winnings for a chance to double or multiply them – handle with care.

Slot game bonus features

These game features are usually triggered by special symbols or combinations. Most popular online slots bonus rounds include free spins features, re-spins, and pick-a-bonus rounds.

Autoplay

A set of automatic slot spins. Some games allow you to stop the autoplay feature if you land a winning payline or trigger a bonus round.

Re spins

A repetition of any single spin when a suitable payline pattern is activated or when special symbols trigger it.

Tumbling reels

A different slot mechanic where symbols fall instead of spinning, as in Gonzo’s Quest.

Wild symbols

Special symbols that replace other symbols to generate winning combinations.

Scatter symbols

Scatter symbols can appear on any reel and they activate various slots bonus rounds, as it happens in Piggy Riches Megaways and many other games.

Win-both-ways feature

A feature allowing winning combinations to form from both left to right and right to left.

Expanding wilds

Symbols that cover an entire reel or row during slots bonus rounds.

Stacked wilds

Wild symbols that appear stacked on top of each other on a reel.

The traditional fruit machine or poker machine with 3 reels and 3 rows.

Video slots

Slot games developed with a narrative and more attention to graphic detail like Rainbow Riches Megaways from Barcrest, or Microgaming’s Immortal Romance.

Progressive jackpot slot

Daily jackpot games

A popular interpretation of must-hit-by progressive jackpots, which don’t necessarily have a fixed value, but only a predetermined time when they will be randomly triggered by a player.

Hit frequency

A metric of how frequently a slot pays out, with the average value being at 20%-30%.

Volatility

A metric of how risky the game is, meaning how likely it is not to return winnings in predictable short-term patterns, but overcompensate later on – only suitable for big bankrolls.
