Online slots make up a significant part of most online casino game libraries.
But a good slots casino isn’t simply the operator advertising the largest number of games.
At UK Casino Play, we compare regulated UK casinos based on slot variety, game providers, mobile usability, navigation, promotions and responsible-gambling features.
Our current casino reviews cover Betway, Coral, Ladbrokes and Hippodrome Casino.

Hippodrome Casino Slots
Hippodrome says its online casino provides access to more than 450 casino games.
Its online offering includes slots alongside traditional casino games such as roulette, blackjack, baccarat and video poker.
One interesting aspect of Hippodrome’s online casino is that some of the games available online are also associated with the casino experience at its London venue.

Coral Slots
Coral provides a substantial slots offering as part of its wider casino.
Players can browse categories that include:

Ladbrokes Slots
Ladbrokes provides online slots alongside table games, live casino gaming and its sportsbook.
Its slots catalogue covers a variety of themes and game formats from multiple casino software providers.
Players interested specifically in slots should compare the current catalogue rather than choosing Ladbrokes purely because of the wider brand.

What We Look for in a Slots Casino
Game Variety
We look at the types of slots available rather than just the headline number.
These can include:
- Classic slots
- Video slots
- Megaways
- Jackpot games
- New releases
- Branded games
Software Providers
Different game developers produce very different types of slots.
A broad range of established providers can therefore be more useful than simply having thousands of similar titles.
Navigation
Can you actually find the games you want?
Search, categories, favourites and provider filters can make a large catalogue considerably easier to use.
Mobile Experience
Slots are commonly played on mobile devices.
We therefore consider how well games and casino navigation adapt to smaller screens.
Promotions
Free spins are commonly used in casino promotions.
We consider the conditions attached to them rather than simply counting the number advertised.
Understanding RTP
RTP means Return to Player.
It’s a theoretical long-term percentage describing how much of the money wagered on a game is expected to be returned to players over a very large number of plays.
For example, a theoretical RTP of 96% does not mean that if you stake £100 you will receive £96 back.
Individual sessions can produce very different outcomes.
RTP is a long-term statistical measure, not a prediction of what will happen during your session.
Slot Volatility
Volatility describes the general payout pattern of a slot.
Lower-volatility games tend to produce smaller wins more frequently.
Higher-volatility games can have longer periods without wins while offering the possibility of larger payouts when certain combinations occur.
Neither type guarantees better results.
What Are Megaways Slots?
Megaways is a slot mechanic where the number of symbols and possible ways to form winning combinations can change between spins.
It’s now widely used across online slot games.
The exact rules vary by title, so check the individual game’s information and paytable.
What Are Jackpot Slots?
Jackpot slots include prizes that can be considerably larger than standard game payouts.
Some use fixed jackpots while others use progressive jackpots that can increase until they’re won.
A large displayed jackpot shouldn’t be interpreted as an indication that you’re likely to win it.
Which Slots Casino Is Best?
Among the four operators currently reviewed by UK Casino Play:
Betway offers a broad dedicated slots catalogue covering multiple categories.
Hippodrome combines online slots with the identity of its famous London casino.
Coral offers slots, Megaways and Slingo through its broader gambling platform.
Ladbrokes combines a substantial slots offering with table games, live casino and sports betting.
The best choice depends on the particular games, providers and experience you prefer.
Can You Play Slots on Mobile?
Yes.
The casinos reviewed by UK Casino Play provide mobile access to online slots.
Modern slot games generally resize automatically for smartphone and tablet screens.
Betway, for example, provides slots through both supported mobile browsers and its iOS and Android apps.
Are Online Slots Random?
Slots offered to UK customers through licensed operators must comply with applicable regulatory and technical requirements.
RNG-based slots generate independent outcomes.
A previous spin doesn’t make a win on the next spin “due.”
Gamble Responsibly
Slots can move very quickly, which makes it easy to lose track of spending.
Set limits before playing and don’t increase your stakes to try to recover previous losses.
Casino games are entertainment, not a way to make money.
