King of the Streets (Slotmill) Slot Review

King of the Streets: Slot Overview 

Released on June 17, 2025, King of the Streets is a bold and gritty slot experience from Slotmill, a provider known for its distinctive visuals and thrilling mechanics. A spiritual successor to Coins and Cannons (2024), this 6×6 cluster-paying slot swaps pirates for prohibition-era gangsters, with the ferocious Don Corlion—a lion in a purple pinstripe suit—leading the criminal underworld. It’s a setting dripping with machismo, old-school mobster charm, and serious bonus firepower. 

Designed for players who enjoy high volatility, King of the Streets offers a maximum win of 15,000x the bet, an RTP of 96.04%, and multiple entry points to its intense feature suite. But beyond its numbers, this game aims to immerse players in a noir-like narrative full of risk, reward, and roaring ambition.

Design and Graphics 

Slotmill once again flexes its muscles in the visual department. The design is soaked in gangster nostalgia, with the game screen framed by skyscrapers and old-school cars, exuding a stylized New York cityscape. Don Corlion is a charismatic lion boss with expressive animations and a commanding presence that gives the game character and personality.Symbols range from poker suits to guns, cigars, whiskey glasses, and glinting coins. Every visual element reinforces the underworld theme, right down to the backdrop of The Lion’s Den—a smoky underground club where shady deals are made and dreams are gambled. 

Animations are fluid and dynamic, with explosive symbol drops, lighting effects when multipliers hit, and special cues for Avalanche wins and bonus entries. From street-level grunge to plush interiors, King of the Streets nails the aesthetic.

Gameplay Mechanics 

This is a 6×6 cluster pays slot where wins are formed when at least five identical symbols are connected horizontally or vertically. Thanks to the Avalanche mechanic, winning symbols are removed and replaced by new ones, allowing consecutive wins on a single spin. 

One of the game’s strategic hooks is the Xtra-Bet option, which increases the stake by 50% but boosts the chance of triggering Free Spins by 2.8x—a tempting offer for those chasing feature rounds. The overall volatility is high, making for a more swingy ride geared toward high-stakes players. 

The standout feature, however, is the interplay of cluster wins and multipliers. Every symbol cleared from the grid opens up potential for Coin Clusters, Multiplier Safes, and symbol-enhanced drops that continuously evolve the game state.

Sound and Music 

The audio design is immersive and complementary. A jazzy soundtrack with moody undertones plays in the background, setting a smoky, suspenseful vibe reminiscent of 1920s speakeasies and gangster flicks. When the action intensifies, especially during Free Spins or Super Free Spins, the music picks up tempo and the sound effects layer in gun clicks, coin jingles, and electric zaps that signify special symbol activations. 

Slotmill has ensured that the audio cues are not only thematic but also informative, letting players know when something significant is happening on-screen.

Bonus Features 

King of the Streets offers a full suite of powerful features that blend together seamlessly:Avalanche 

All winning symbols (and all symbols of the same type) are removed from the grid. A wild then spawns in one of the cleared spaces, continuing the cascade. This repeats as long as new wins land. 

Coin Clusters 

Coin symbols have values of 1x to 40x the bet. If a cluster of 5+ coin symbols forms, the total coin value is summed, and that value is awarded. After payout, a new coin with the total multiplier appears in a fresh space before the next Avalanche. 

Multiplier Safe 

A persistent game-changer. These symbols hold values ranging from 2x to 500x. They remain on the reels during cascades and are summed at the end of the round to multiply the total win. They are especially impactful during bonus rounds. 

Free Spins 

Triggered by landing 3 scatter symbols, this feature awards 10 free spins. During these spins, any Multiplier Safe values are added to a total multiplier, which is applied to all wins and doesn’t reset between spins. Players can also earn extra free spins via +1 symbols. 

Super Free Spins 

Even juicier. Land 2 scatters and a Super Free Spins symbol, and you’ll unlock 10 Super Free Spins. During this mode, leftover Coin symbols accumulate at the bottom of the screen, allowing for massive cluster win potential. 

Fast Track 

For those who prefer direct access to bonus content, Slotmill offers buy-in options:100x for Free Spins 

500x for Super Free Spins 

40x for a guaranteed Multiplier Safe round 

This Fast Track feature provides instant gratification and is useful for high-rollers or testers alike.

Betting Options and Payouts 

King of the Streets accepts bets from €0.25 to €50, offering flexibility across different bankrolls. The game is clearly tailored to cater to those who enjoy high-risk, high-reward experiences. 

Cluster payouts vary depending on the number of matching symbols: 

5-symbol clusters pay 0.2x to 1x the bet 

14+ clusters can pay up to 50x the bet 

Add the Coin Cluster wins and the Multiplier Safe mechanics into the mix, and you have a game that’s capable of delivering explosive payouts, especially during bonus modes. 

The maximum win stands at a staggering 15,000x the bet, putting it in the same tier as slots like Gates of Olympus or Money Train 4. However, it’s worth noting that regular base game spins may feel dry in between feature hits—typical for a high volatility title.

Conclusion 

Slotmill has struck gold with King of the Streets. It’s more than just a thematic re-skin of Coins and Cannons—it’s a thoughtfully upgraded slot with engaging features, tactical gameplay, and dizzying win potential. The game’s design oozes style, from the streets of faux-1920s New York to the fierce lion king himself. Add to that a slick user interface, cinematic audio, and a dense web of bonus mechanics, and you have a slot that’s built for serious thrill-seekers. 

Sure, the high volatility and complex feature layering may not suit casual players, but for experienced spinners who relish high-octane sessions and calculated risk, King of the Streets is a must-play. With a top payout of 15,000x and a gripping bonus round structure, this title confidently steps out of its predecessor’s shadow to claim its place in Slotmill’s top-tier lineup.
