The Best Grosvenor Casino Slots

Big Bass Splash

• RTP: 96.71%
• Progressive Jackpot: No
• Best Feature: Free Spins with Multiple Modifiers

Big Bass Splash from Pragmatic Play uses a fishing theme with symbols like fish, a tackle box, fishing rod, truck, and the angler wild. The action takes place on a colourful underwater backdrop.

This is a high volatility slot, so wins don’t land often, but the potential payouts can be significant. The maximum win is 5,000× your stake, most likely to be hit during the bonus round.

The Free Spins feature is triggered by three or more scatters, awarding 10–20 spins depending on how many land. Before the round begins, up to five modifiers can activate, such as extra fish symbols, added wilds, hooks, dynamites, bazookas, or extra spins. These boost the feature and increase winning chances.

With its 96.71% RTP and big-win potential, Big Bass Splash is best for players who prefer a higher risk-and-reward style of play. If you enjoy fishing-themed slots with strong bonus rounds, this one is a natural catch at Grosvenor Casino.

Zeus Hyper Frames

• RTP: 96%
• Progressive Jackpot: Yes (via Lightning Multiplier)
• Best Feature: Hyper Frames & Enhanced Bonus Modes

Zeus Hyper Frames from Snowborn Games brings a Greek mythology theme featuring stacked wilds and a modern twist on the classic god-of-thunder aesthetic. The setup uses 5 reels, 3 rows, and 243 ways to win, offering players a familiar yet refined layout.

With an RTP of 96% and medium volatility, this slot strikes a balance between frequent wins and meaningful payouts. The maximum win can reach an impressive 6,200× your stake, making it especially appealing during feature play.

The main draw is the Hyper Frames bonus: land six or more bonus symbols simultaneously to trigger the Free Spins round and begin building frames around triggering symbols. These frames can be upgraded from bronze to silver to gold as more bonus symbols hit, unlocking three enhanced bonus variants—Super Gold, Super Spinz, and Super Stackz—each offering different ways to magnify win potential and gameplay variety.

Additionally, the Lightning Multiplier can randomly activate upon a jackpot win, boosting the reward by a multiplier of 2×, 3×, or 5×.

At a 96% RTP with moderate volatility, Zeus Hyper Frames suits players who appreciate a balanced risk profile—but who also want the excitement of inventive bonus mechanics and the chance for a sizable jackpot. If you’re looking for a myth-themed slot with clever features and decent win opportunities, this one is a strong pick for your Grosvenor slots lineup.

Cleopatra

• RTP: 95.02%
• Progressive Jackpot: No
• Best Feature: Free Spins with Tripled Wins

Cleopatra, a classic slot from IGT, features a well-crafted Egyptian motif with symbols like Cleopatra as the Wild, scatters represented by the Sphinx, and a backdrop reminiscent of tombs and hieroglyphs.

With a 95.02% RTP and low-to-medium volatility, this game is geared toward players who prefer steady wins over long sessions rather than chasing big jackpots. The top payout is an impressive 10,000× your stake, achievable by landing five Cleopatra Wilds on a payline during the Free Spins or base game.

To trigger the Free Spins feature, you need three or more Sphinx Scatter symbols. You’ll receive 15 Free Spins, and landing another three during the round can retrigger up to 180 spins in total. Importantly, every win in the Free Spins round is tripled, making this one of the most straightforward but effective bonus mechanics around.

Ideal for players who appreciate straightforward gameplay with reliable bonus value, Cleopatra brings a familiar and trusted experience to the Grosvenor Casino slots selection.

9 Pots of Gold

9 Pots of Gold offers a vivid Irish luck theme, featuring symbols like pots of gold, shamrocks, four-leaf clovers, leprechaun hats, harps, and a mushroom wild, set against a lush green Celtic background with cheerful audio.

This is a medium volatility slot with a 96.24% RTP, which gives a balanced experience—enough action and occasional wins without extreme fluctuations.

The game’s standout feature is the Pot Pays mechanic: collecting 3–9 pot scatter symbols awards instant cash prizes from 1× up to a top pay of 2,000× your bet. The larger amounts come when more scatter symbols appear together.

It also includes a Free Spins round, triggered by landing three Free Spin symbols (typically on reels 2, 3, and 4). This opens a wheel that offers 10–30 free spins with a 2× or 3× multiplier, which applies to all wins during the round.

With its solid RTP, moderate volatility, and a combination of scatter pays plus multipliers, 9 Pots of Gold is a great fit for players who enjoy thematic slots with a mix of regular payouts and feature-driven win potential.

This slot comes with high volatility and a respectable 96% RTP, offering less frequent but potentially rewarding wins. The maximum win potential is a notable 21,000× your stake, especially within bonus features.

The gameplay centers on Avalanche Reels, where winning symbols disappear and new ones fall into place, triggering cascading payouts and increasing multipliers up to 5× in the base game and up to 15× during Free Falls. Added depth comes from Unbreakable Wilds that stay active across avalanches, and the Earthquake feature, which can remove low-paying symbols mid-spin to make room for higher-value ones.
