Not all slots are built the same. Understanding the different types helps you find games that match your style, your budget, and the kind of session you’re looking for.
| Slot Type | How It Works | Best For |
|---|---|---|
| Classic Slots | 3 reels, simple paylines, traditional fruit and bar symbols | Players who prefer straightforward, fast-paced gameplay |
| Video Slots | 5+ reels, multiple paylines, bonus rounds, free spins, wilds, scatters | Most players; the broadest and most popular category |
| Megaways Slots | Random reel modifier, up to 117,649 ways to win per spin | High-volatility fans who enjoy big win potential |
| Progressive Jackpot Slots | Prize pool grows with every bet across the network | Players chasing life-changing payouts |
| Fixed Jackpot Slots | Set maximum win amount regardless of player activity | Those who prefer known maximum payouts |
| Cluster Pay Slots | Wins form through clusters of matching symbols rather than paylines | Players who like grid-based puzzle-style mechanics |
| Cascading Reels Slots | Winning symbols disappear and new ones fall in, creating chain reactions | Players who enjoy multiple wins from a single spin |
We carry all of these types and more. Our lobby updates several times a week with new releases, so there’s always something fresh to explore.
Popular Online Slots in the UK
Some online slots have stood the test of time and remain firm favourites with UK players. Here are some of the most-played titles in our lobby, along with what makes each one worth a spin.
Starburst (NetEnt)
Starburst is one of the most widely played online slots in UK casino history, and it’s easy to see why. It’s a 5-reel, 10-payline game with an RTP of 96.09% and low-to-medium volatility. The expanding Starburst Wild triggers re-spins across the middle three reels, creating frequent small-to-medium wins. It’s simple, colourful, and a great starting point if you’re new to online slots.
Big Bass Bonanza (Pragmatic Play)
Big Bass Bonanza is one of the most successful slot franchises in recent years. It’s a 5-reel, 10-payline fishing-themed slot where landing three or more scatter symbols triggers free spins. During the bonus round, fisherman symbols collect the values of any fish symbols on screen. The series has expanded into multiple sequels including Big Bass Splash, Big Bass Bonanza Megaways, and Big Bass Secrets of the Golden Lake, all of which are available in our lobby.
Rainbow Riches (Light & Wonder)
Rainbow Riches is a classic of UK slot gaming. Originally released for land-based machines, the online version keeps everything players love: the Road to Riches bonus, the Wishing Well pick feature, and the Pots of Gold bonus round. It has an Irish theme with a friendly leprechaun character, medium volatility, and an RTP around 95%. The franchise has spawned dozens of sequels and spin-offs, many of which you’ll find here.
Gonzo’s Quest (NetEnt)
Gonzo’s Quest was one of the first slots to use cascading reels (NetEnt calls them “Avalanche” reels). Instead of spinning, symbols fall into place, and winning combinations disappear to let new symbols drop in. Each consecutive cascade in a single spin increases the multiplier, up to 5x in the base game and 15x during free falls. It’s a 5-reel, 20-payline game with an RTP of 95.97% and medium volatility.
Book of Dead (Play’n GO)
Book of Dead is a high-volatility, Egyptian-themed adventure slot with 5 reels and 10 paylines. The Book symbol acts as both wild and scatter, and landing three or more triggers 10 free spins. Before the free spins begin, a random symbol is chosen to expand across entire reels when enough appear. With an RTP of 96.21%, it rewards patience and can deliver substantial payouts during the bonus round.
Megaways Slots UK
Megaways is one of the most exciting developments in online slots over the past decade. If you enjoy high-energy, high-volatility gameplay with massive win potential, this section of our lobby is worth exploring first. We carry 100+ Megaways titles.
How Megaways Works
The Megaways mechanic was created by Big Time Gaming and is licensed to other studios. On each spin, the number of symbols on each reel changes randomly. A standard six-reel Megaways game can produce anywhere from 324 to 117,649 ways to win on a single spin. There are no fixed paylines; instead, matching symbols on adjacent reels from left to right create wins.
Most Megaways slots also feature cascading reels: winning symbols are removed and replaced by new ones falling from above. This means multiple wins can occur from a single spin, and many Megaways games increase a multiplier with each consecutive cascade.
Popular Megaways Titles in Our Lobby
| Game | Provider | Key Feature |
|---|---|---|
| Bonanza Megaways | Big Time Gaming | The original Megaways slot; mining theme with unlimited multiplier in free spins |
| Gonzo’s Quest Megaways | Red Tiger / NetEnt | Cascading reels with earthquake feature and increasing multipliers |
| Big Bass Bonanza Megaways | Pragmatic Play | Fish-collecting mechanic combined with Megaways ways-to-win |
| Eye of Horus Megaways | Blueprint Gaming | Egyptian theme with expanding symbols during free spins |
| Fishin’ Frenzy Megaways | Blueprint Gaming | Fisherman feature with cash-value fish symbols |
| Wolf Gold Megaways | Pragmatic Play | Hold and Win jackpot feature built into a Megaways format |
Things to Know About Megaways Slots
- High volatility – Megaways games almost always feature longer dry spells between wins, but when wins arrive, they can be significant
- RTP range – typically 95% to 96.5%, similar to other video slots
- Variable reels – the changing reel setup means every spin feels different, which is a big part of the appeal
- Cascading wins – most Megaways slots remove winning symbols and drop new ones in, allowing multiple wins from a single spin
- Increasing multipliers – many Megaways games boost the multiplier with each consecutive cascade during free spins
If you’re used to fixed-payline slots, Megaways can feel like a different game entirely. We’d suggest trying a few in demo mode first to get a feel for how the mechanics work before playing with real money.
Progressive Jackpot Slots
Looking for the chance to land a life-changing win from a single spin? Our progressive jackpot collection is the place to be. We host 150+ jackpot titles, split between progressive and fixed jackpots.
How Progressive Jackpots Work
Progressive jackpots pool a small fraction of every bet placed on the game across the entire network of casinos offering it. That means every player spinning the same progressive slot, regardless of which casino they’re playing at, contributes to the same prize pool. The jackpot keeps growing until one player triggers it.
Once hit, the jackpot resets to a seed value and starts building again. Some progressive jackpots have paid out seven-figure sums.
Notable Progressive Jackpot Titles
| Game | Provider | Jackpot Type | RTP |
|---|---|---|---|
| Divine Fortune | NetEnt | Three-tier progressive (Minor, Major, Mega) | 96.59% |
| King Cashalot | Microgaming | Single progressive jackpot | 90.70% |
| Age of the Gods series | Playtech | Four-tier progressive (Power, Extra Power, Super Power, Ultimate Power) | 94.03-95.02% |
| Mega Moolah | Microgaming | Four-tier progressive; historically one of the largest online jackpots | 88.12% |
| Sisters of Oz WOWPot | Games Global | WOWPot network jackpot | 92.50% |
Jackpot RTP: What to Know
You’ll notice that progressive jackpot slots tend to have lower RTPs than standard video slots. That’s because a portion of each bet feeds the jackpot pool rather than going back to players through regular wins. King Cashalot at 90.70% or Mega Moolah at 88.12% are significantly lower than the 96%+ you’ll find on most video slots.
This is the trade-off: lower regular returns in exchange for the chance at an enormous payout. If you primarily enjoy consistent, steady gameplay, standard video slots with higher RTPs may suit you better. If the dream of a massive jackpot appeals, progressives offer that possibility but are best played with a bankroll you’re comfortable with.
Understanding RTP and Volatility
Every online slot has two key numbers that tell you a lot about how it plays: RTP and volatility. Understanding both helps you make more informed choices about which games suit your style and budget.
Return to Player (RTP)
RTP stands for Return to Player and is expressed as a percentage. A slot with 96% RTP will, over millions of spins, return £96 for every £100 wagered. The remaining 4% is the house edge, which is how every casino generates revenue.
Two important things to understand about RTP. First, it’s calculated over millions of spins, not a single session. In any given session, you could win significantly more than the RTP suggests, or you could lose your entire balance. Second, operators can sometimes select different RTP configurations from the same provider. The same game might run at 96.5% at one casino and 94.5% at another. We’d always encourage you to check the RTP in each game’s info panel before playing.
Volatility (Variance)
Volatility describes the pattern of payouts. It works alongside RTP to give you a fuller picture of what to expect.
| Volatility Level | What It Means | Example Games |
|---|---|---|
| Low | Frequent smaller wins; bankroll lasts longer | Starburst, Blood Suckers |
| Medium | Balanced mix of win frequency and size | Gonzo’s Quest, Thunderstruck II |
| High | Less frequent wins, but larger when they hit | Book of Dead, Bonanza Megaways |
| Very High | Long dry spells; potential for very large payouts | Dead or Alive 2, San Quentin |
Neither low nor high volatility is objectively better. It depends on what kind of experience you enjoy. Low-volatility games suit longer, steadier sessions. High-volatility games deliver more dramatic swings and are better suited to players who are comfortable with the risk of longer losing streaks in exchange for bigger win potential.
Slot Features and Bonus Mechanics
Modern online slots come packed with features that go well beyond spinning reels. Knowing what each feature does helps you understand a game’s mechanics and get more out of your playing time.
Wilds
Wild symbols substitute for other symbols to help complete winning combinations. Common wild types include:
Expanding Wilds – stretch to cover an entire reel when they land
Sticky Wilds – stay locked in place for multiple spins
Walking Wilds – move one position across the reels on consecutive spins
Multiplier Wilds – multiply the value of any win they help create
Scatter Symbols
Scatters typically trigger bonus features regardless of their position on the reels. In most slots, landing three or more scatters activates free spins. Some scatters also pay out a multiplier of your total bet.
Free Spins
Free spins are the most common bonus feature. You spin a set number of times without it costing your balance. Free spin rounds often come with added benefits like increased multipliers, extra wilds, or expanded reels.
Multipliers
Multipliers increase your winnings by a set factor. A 3x multiplier turns a £5 win into £15. They can appear in the base game, during free spins, or as part of cascading reel mechanics where consecutive wins increase the multiplier.
Bonus Buy (Feature Buy)
Some slots let you skip the base game and buy direct access to the bonus round for a fixed price, usually between 50x and 100x your stake. This is higher variance than playing normally, since you’re paying upfront for a feature that might not return your investment. Available on selected games from providers like Pragmatic Play, Nolimit City, and Hacksaw Gaming.
Hold and Win / Respins
Hold and Win features lock specific symbols in place and give you a set number of respins to land more matching symbols. Each new symbol resets the respin counter. These mechanics often appear in jackpot-style games and can deliver large payouts when the grid fills up.
UK Slot Stake Limits
Since 2025, the UKGC has introduced mandatory stake limits for online slots at all UK-licensed casinos. These limits apply to slots only and do not affect table games, live casino, or other game types.
| Player Age | Maximum Stake Per Spin |
|---|---|
| 25 and over | £5 |
| 18-24 | £2 |
These limits are set by regulation and apply across every UK-licensed casino, not just ours. They were introduced as part of the Gambling Act review to provide additional protection, particularly for younger players. The minimum spin duration is also set at 2.5 seconds.
If you’ve played online slots in the UK before these limits came in, you may notice that some high-stakes options are no longer available. The limits are designed to reduce the risk of harm during extended play sessions.
How Online Slots Work
If you’re new to online slots or just curious about what happens behind the scenes, here’s a clear explanation of how every spin is determined.
Random Number Generators (RNG)
Every online slot uses a Random Number Generator, a computer algorithm that produces thousands of random number sequences per second. When you press the spin button, the RNG selects a sequence that determines where each reel stops and what symbols appear. The outcome is decided the instant you press spin; the reel animation is simply a visual representation of a result that’s already been determined.
This means every spin is independent. Previous results have no influence on future spins. A slot that hasn’t paid out in 100 spins is no more likely to pay out on spin 101 than on any other spin. There is no such thing as a slot being “due” for a win.
Are Online Slots Fair?
All slots offered at Conquer Casino are supplied by licensed providers and tested by independent auditing firms. Our games run on the ProgressPlay platform, which operates under UKGC licence 39335. The UKGC requires regular audits of RNG systems to verify that outcomes are genuinely random and that published RTPs are accurate.
You can check the RTP and rules for any game by opening its info or help panel. This transparency is a requirement of UK regulation, and it’s there to give you confidence that every spin is fair.
Mobile Slots
Every UK slot in our library works on mobile. Whether you’re on an iPhone, Android phone, or tablet, you can access the full range of online slots through your mobile browser with no app to download.
Games are built using HTML5 technology, which means they automatically resize to fit your screen. Touchscreen controls replace the mouse clicks, and the interface adapts to portrait or landscape orientation. You won’t miss out on any features, bonus rounds, or graphics quality compared to playing on desktop.
Our slot lobby loads quickly on mobile, and you can search or filter by game type, provider, or theme to find what you’re looking for without scrolling through thousands of titles. You can also deposit, withdraw, and manage your account entirely from your phone.
If you enjoy a quick spin during a commute, a break, or from the sofa, the experience is the same as sitting at a desktop.
