Coins and Cannons (Slotmill) Slot Review

Coins and Cannons: Slot Overview 

Slotmill has returned to what it does best—creating sharp, lively, and feature-rich slots—with the release of Coins and Cannons on September 3, 2024. This high-volatility slot brings together two of the studio’s most successful ideas: Cluster Pays and Coin mechanics, wrapped in a bright and breezy pirate theme that sets sail on a 6×6 grid. It’s a spiritual successor to games like Coin Quest and Coin Quest 2, but with a distinctly lighter tone and some meaningful mechanical shifts. 

Gone is the Coin Quest Collect Meter. Instead, Coins and Cannons replaces it with Multiplier Cannons—symbols that can dramatically boost your wins by up to 100x. Players still benefit from Coin Clusters, which explode and regenerate, and the Avalanche mechanic keeps the action flowing. Add in a choice of Free Spins, Super Free Spins, and even a Fast Track menu, and you’ve got a slot with energy, variety, and explosive potential, topped by a 15,000x max win.

Design and Graphics 

Visually, Coins and Cannons is a colorful detour from Slotmill’s usual dark or epic settings. It throws players onto a sun-kissed beach next to a pirate ship, with golden treasure gleaming in the distance and rock formations shaped like skulls adding a bit of cheeky flair. The game’s bright aesthetic immediately sets it apart from more brooding pirate slots. The 6×6 grid is framed in weathered wood, packed with vibrant symbols like: 

• Gemstones in multiple colors (blue, green, red, purple) 

• Card suits (hearts, clubs, diamonds, spades) 

• Pirate skulls as premium symbols 

• Coins and Cannons (the main feature symbols) 

Animations are fluid and fun—symbols pop off the reels with each win, and the Cannon Multipliers land with a satisfying boom. It’s got all the personality of a cartoon pirate adventure without feeling juvenile.

Gameplay Mechanics 

Coins and Cannons utilizes a 6×6 cluster pays grid, with wins formed by landing 5 or more matching symbols connected vertically or horizontally. When a win occurs, the Avalanche mechanic kicks in—winning symbols disappear, and new ones fall from above. The grid stays alive as long as new clusters keep forming. 

The minimum and maximum bets range from €0.20 to €50, placing it within easy reach of both casual players and mid-level risk-takers. With an RTP of 96.08% and high volatility, it’s a game that plays the long game—expect dry spells broken by high-impact feature rounds. 

There’s no payline math to worry about here. Instead, you’re chasing symbol clusters, Coin explosions, and the perfect Cannon Multiplier combo that can turn modest wins into serious payouts.

Sound and Music 

The soundtrack matches the game’s sunny pirate vibes perfectly. A cheerful, upbeat tune loops in the background, complete with jaunty string instruments and light percussion that evoke a sense of tropical mischief. It’s bright, but not intrusive. 

Sound effects are well-placed and satisfying. Avalanches trigger crisp pops, Coin Clusters sparkle and hum with energy, and Cannon Multipliers slam onto the reels with bassy thuds that amplify their impact. During free spins, the music shifts into a more suspenseful groove, underscoring the raised stakes. 

Overall, Slotmill has created an audio package that is fun, fast-paced, and polished—no sea shanties required.

Bonus Features 

Coins and Cannons is a slot where features are constantly in motion, even in the base game. Avalanche 

Every winning cluster causes an Avalanche, clearing winning symbols and dropping new ones from above. After each Avalanche, a wild symbol is guaranteed to land in one of the empty spots (except during Coin Cluster wins). 

Coin Clusters 

These are the stars of the show. Coin symbols can land with values between 1x and 40x your bet. When 5+ Coin symbols form a cluster, they explode, awarding their combined bet multiplier total. Then, one new Coin lands in the empty space left behind, carrying the total win value of the cluster. These do not generate wilds but often lead into follow-up cascades and payouts. 

Cannon Multiplier 

The Multiplier Cannon symbol is a powerhouse—it lands with values ranging from x2 to x100. When there are no more winning combinations left, all Cannons on the screen combine their values and are applied to the total round win. 

This feature is especially powerful when used with Coin Clusters, where Cannon multipliers can exponentially boost payout totals. 

Free Spins 

Landing 3 scatter symbols in the base game triggers 10 Free Spins. During this bonus: 

• Coin symbols remain at the bottom of the grid until the round ends 

• Hitting a +1 symbol awards an extra spin 

• Avalanche wins and Multipliers remain active, increasing the odds of substantial returns 

Super Free Spins 

Triggering this mode requires 2 regular scatters + 1 Super Free Spins scatter, also awarding 10 spins. In this version: 

• A Multiplier Cannon is guaranteed to land on every spin 

• Coin Clusters, Avalanches, and bonus mechanics remain fully active 

This mode brings serious potential, particularly when high-value Cannons land consistently. 

Fast Track 

Slotmill’s Fast Track feature buy menu offers direct access to bonus rounds: 

Multiplier Cannon: 40x bet 

Free Spins: 100x bet 

Super Free Spins: 500x bet 

This system is ideal for players who want to skip the base grind and dive into the slot’s most lucrative features.

Betting Options and Payouts 

With a betting range of €0.20 to €50, Coins and Cannons suits a wide audience, although the ceiling is a little lower than some Slotmill titles (€60 max). The 15,000x max win figure is impressive, especially considering the frequency and potential of Coin + Cannon combinations. 

Symbol payouts depend heavily on cluster size: 

• 5-symbol clusters: 0.2x to 1.2x your bet 

• 14+ symbol clusters: 6x to 100x 

• Coin values: 1x to 40x per symbol 

• Multiplier Cannons: up to 100x applied to total win 

The potential lies in stacking Coin Cluster wins with Multiplier Cannons in a single round. And during Super Free Spins, the combination of guaranteed Cannons and sticky Coins can lead to wild, runaway wins.

Conclusion 

Coins and Cannons is Slotmill at its creative best—bright, bouncy, and brimming with potential. It delivers complex mechanics in a simple, accessible package and balances high volatility with rapid-fire base game activity. The Coin Clusters bring satisfying chunk-style wins, and the Multiplier Cannons offer a fresh twist that can transform any round. 

While some players might miss the progression systems found in Coin Quest, this game feels like a more dynamic, more immediately rewarding evolution. It’s a “just one more spin” type of slot—one that’s cheerful on the surface but has real teeth underneath, especially in Super Free Spins mode. 

With a 96.08% RTP, up to 15,000x potential, and a feature set that doesn’t rely on elaborate setups or progression bars, Coins and Cannons sails smoothly into the upper ranks of Slotmill’s portfolio. For fans of Cluster Pays, Coin mechanics, and high-volatility chaos, this one’s a treasure worth digging up.
