Most players who land on a slots page want one number: the RTP. At Pub Casino that number is the first thing you can't easily find. The category pages don't print per-game RTP — you have to open each title to see it, and even then a few are missing. So this page does the work for you. I've gone through the slots Pub actually features, separated the titles with verified figures from the ones where the data isn't published, and laid out RTP, volatility and max win side by side. One thing to settle before you spin: bonus buy is switched off for players in England. That's a UKGC rule, not a Pub quirk — every GB-licensed casino disables the feature buy. Knowing that up front saves the disappointment of seeing a "Buy Bonus" button greyed out.
What slots are available at Pub Casino?
Pub Casino runs a mixed library — counts reported across review sites range from roughly 2,000 to 3,000+, which tells you the menu is large but not that anyone has counted it precisely. The titles it pushes to the front lean British and recognisable: Big Bass Splash, Eye of Horus, Fishin Frenzy. Providers behind them include Pragmatic Play, Blueprint Gaming, Fortune Factory Studios and Octoplay. Mechanics split into three broad types — standard payline slots, cluster/tumble titles like Gates of Olympus 1000, and Hold & Win games such as Gold Blitz Ultimate and Break the Piggy Bank.
Here's the honest version of the featured list. Where Pub or a reliable database publishes the numbers, you'll see them. Where they don't, it says so — I'd rather leave a gap than invent an RTP.
| Slot | Provider | RTP | Volatility | Max win | Bonus Buy | Demo | Notes |
|---|---|---|---|---|---|---|---|
| Big Bass Splash | Pragmatic Play / Reel Kingdom | 96.71% | High | 5,000x | Blocked (GB) | Yes | RTP and max win verified; feature buy disabled for England |
| Gates of Olympus 1000 | Pragmatic Play | 96.5% | V.High | 15,000x | Blocked (GB) | Yes | The "1000" edition — 15,000x, not the original 5,000x version |
| Fishin Frenzy | Blueprint Gaming | Unknown | Medium | Unknown | No | Yes | Figures not published in reviewed sources — open the title to check |
| Eye of Horus | Blueprint Gaming | Unknown | Medium | Unknown | No | Yes | Egyptian favourite; expanding wilds in free spins |
| Gold Blitz Ultimate | Fortune Factory Studios | Unknown | High | Unknown | No | Yes | Hold & Win classic; specs not verified |
| King Kong Splash | Blueprint Gaming | Unknown | High | Unknown | No | Yes | Action slot with bonus features; specs not verified |
| Break the Piggy Bank | Octoplay | Unknown | High | Unknown | No | Yes | Hold & Win title; specs not verified |
Which slots pay the most — RTP and volatility explained
RTP is the long-run figure. A 96.71% slot returns, on average, £96.71 for every £100 staked across millions of spins — not across your session. Two slots can share that number and feel nothing alike. That's volatility. A high-volatility title pays rarely but large; a medium one trickles smaller wins more often. High RTP on a very-high-volatility game does not mean frequent wins. It means the eventual payouts are big enough to drag the average up — between them you can sit through long dry runs.
Below is a ranking by RTP. Only Big Bass Splash and Gates of Olympus 1000 carry figures verified for Pub's own listings; the rest of the ranking draws on a comparison pool of common UK titles to show where the band typically sits.
| # | Slot | RTP | Volatility | What it means for you |
|---|---|---|---|---|
| 1 | Big Bass Splash | 96.71% (verified) | High | Strong RTP, but wins cluster in the free-spins round |
| 2 | Gates of Olympus 1000 | 96.5% (verified) | V.High | Big ceiling, brutal variance — short sessions can show nothing |
| 3 | 9 Coins [fallback data] | 96.8% | High | Reference figure from comparison pool, not Pub-specific |
| 4 | Gems Bonanza [fallback data] | 96.51% | High | Tumble mechanic; reference figure only |
| 5 | Fruit Party [fallback data] | 96.47% | High | Cluster pays; reference figure only |
| 6 | Reels on Fire [fallback data] | 96.1% | Medium | Steadier swings; reference figure only |
The scatter below plots the same idea visually — RTP up the side, volatility across the bottom. Notice how the points sit in a narrow RTP band (96.1–96.8%) but spread right across the volatility scale. That's the lesson in one chart: RTP barely moves between these titles, yet the experience changes completely as you go from medium to very high.
Can you try these slots for free in demo mode?
Most of Pub's featured titles offer a demo. You play with virtual credits, the bonus features behave the same, and you risk nothing. The catch is the obvious one — you can't withdraw demo winnings, because there aren't any. Demo is for learning the mechanic and feeling the volatility before real money is on the table. On a very-high-variance slot, ten minutes in demo will tell you whether you've got the patience for it.
On Pub Casino, demo play is generally available without depositing, though some titles ask you to be logged in. If you haven't registered yet, the sign-up process takes a couple of minutes and unlocks the full library. Remember slots are an 18+ product — demo or real, the age check applies, and you'll need to complete KYC verification before any real-money withdrawal clears.
| Slot | Demo | Login needed? | Difference vs real play | Notes |
|---|---|---|---|---|
| Big Bass Splash | Yes | Usually no | No real winnings; no bonus buy either way (GB) | Good for learning the wild-collection feature |
| Gates of Olympus 1000 | Yes | Usually no | Demo balance hides how fast real funds can drop | Feel the variance before staking real money |
| Fishin Frenzy | Yes | Usually no | Same feature set; no payout | Medium volatility — gentler for new players |
| Eye of Horus | Yes | Usually no | Same expanding-wild feature; no payout | Simple paylines, good demo to start on |
| Gold Blitz Ultimate | Yes | Usually no | Hold & Win round plays identically; no payout | High volatility — test patience in demo first |
Author's tip from Benjamin Clarke, Online Casino Content Manager: "Use demo to count, not to dream. Play fifty spins, see how often a feature triggers, then ask whether your real bankroll could absorb that gap. If the answer is no, the slot is wrong for you — not unlucky."
Which providers power the games at Pub Casino?
The featured shelf leans on a handful of studios, each with a signature. Blueprint Gaming supplies the British-flavoured, mechanic-light slots — Fishin Frenzy, Eye of Horus, King Kong Splash — built for medium swings and recognisable themes. Pragmatic Play brings the higher-variance crowd-pleasers, Big Bass Splash and the cluster-and-multiplier engine of Gates of Olympus 1000. Fortune Factory Studios and Octoplay round things out with Hold & Win titles, where the appeal is the coin-collection bonus rather than the base game.
The chart below counts how many of the featured titles come from each studio — the only fully countable figure on this page, since it's drawn straight from the featured list rather than from RTP databases.
And to close the loop on the headline question — which featured slots carry the biggest ceilings — the final chart ranks the top titles by max win, blending the two Pub-verified figures with the wider comparison pool. Treat the unverified numbers as the band you'd expect from titles of that type, not as confirmed Pub specifications.
Author's tip from Benjamin Clarke, Online Casino Content Manager: "Pick a provider whose style fits your patience, not just a slot whose theme catches your eye. If long dry spells bother you, Blueprint's medium titles will treat you more kindly than a 50,000x monster ever will."
High RTP and high volatility rarely sit in the same title, so it's worth treating them as separate decisions. The free spins page often points at the same games these promotions favour, and the bonus page explains why slots clear wagering faster than table games. For a change of pace, the live casino and sportsbook sit a click away.
