King of the Streets: Slot Overview

Climbing the street ladder from a nobody to the top dog usually means ruffling a few feathers along the way. In Slotmill’s online slot King of the Streets, the spotlight falls on Don Corlion, a character who looks more than willing to trample—or even tear up—any toes standing between him and the crown. And yes, that’s intentional: Don Corlion, public enemy number one, is a lion leading a slot inspired by Coins and Cannons (2024), but with a couple of compelling twists.

You’ll meet the Don almost immediately, posted beside the grid, chain-smoking, occasionally flashing a weapon, and generally projecting a no-nonsense attitude. The setting is a gritty, anything-goes take on 1920s New York, complete with sirens in the background. Trigger or purchase the bonus, and you’re welcomed into the Don’s club, The Lion’s Den, where the real business of smoking, gambling, and acting tough goes down. Slotmill nails a slick gangster atmosphere that’s worlds away from the swashbuckling tone of its predecessor, even though the core gameplay has familiar DNA.

Symbols land in a 6×6 area, and a winning cluster forms when at least 5 matching symbols connect horizontally or vertically. Players can stake 20 c to $/€50, or opt to buy features, switch on the Xtra-Bet, or jump into the rapid-fire Burst Mode. With Xtra-Bet enabled, the wager increases by 50%, and it becomes 2.8 times more likely to trigger free spins. King of the Streets offers a maximum RTP of 96.04% and plays as a highly volatile slot.

The symbol ladder includes diamonds, clubs, hearts, spades, guns, cigars, glasses, knuckle dusters, and Don Corlion. Clusters of 5 OAK pay 0.2x to 1x the bet, scaling up to 14+ clusters that return 6x to 50x the bet. The police badge acts as a wild, replacing all symbols except scatters. If a wild substitutes for Coins, it carries no value of its own.

King of the Streets: Slot Features

For anyone aiming to take over the streets, King of the Streets comes loaded with Avalanches, Coin Clusters, Multiplier Safes, free spins, super free spins, and feature buys.

Avalanche

All symbols part of a win, along with all non-winning symbols that match the winning symbol types, are removed from the grid, causing new symbols to drop into the empty spaces. On top of that, a wild spawns in one of the gaps before the remaining symbols fall. The cycle continues for as long as fresh wins keep appearing.

Coin Clusters

Coin symbols carry a multiplier of 1x-40x the bet. When Coins create a cluster of 5 or more, the multipliers on the Coins in that cluster are summed and paid out. Once awarded, the cluster detonates, and a new Coin showing the total multiplier value of the winning Coin Cluster is placed into one of the empty spots before the next drop.

Multiplier Safe

Multiplier Safe symbols come with a random value of x2 to x500. If wins occur while a Multiplier Safe is on the reels, it stays in place until the round stops producing wins. After that, all Multiplier Safe values are added together, and the combined multiplier is applied to the round’s total win.

Free Spins

Landing 3 scatters grants 10 free spins. In the free spins bonus, whenever a Multiplier Safe appears and the spin results in a win, the Multiplier Safe value is added to a total multiplier, which then multiplies that spin’s win. Throughout the feature, the total multiplier does not reset. Hitting a +1 Spin symbol during the round awards an extra free spin.

Super Free Spins

Hitting 2 scatters plus a super free spins scatter awards 10 super free spins. During this mode, leftover Coin symbols collect along the bottom of the reels, keeping them in play for new winning combinations until the feature ends. Aside from that, the free spins rules also apply to super free spins.

Fast Track

Fast Track lets players purchase free spins or super free spins for 100x or 500x the bet, respectively. Players can also buy a round that starts with a triggering Multiplier Safe for 40x.

King of the Streets: Slot Verdict

If you enjoyed clustering Coins while playing pirate in Coins and Cannons but thought it could use a heavier dose of crime, this is exactly that wish fulfilled. Slotmill has taken the framework of Coins and Cannons, swapped the open seas and salty air for a dense city backdrop, and topped it off with a criminally inclined lion to create King of the Streets. Beyond the shared foundation, Slotmill has made additions and removals—both small and significant—that noticeably change how the game unfolds. Still, Coins and Cannons remains the best indicator: if that one hit the spot, this likely will too.

Some of the lighter tweaks include a slightly lower RTP, balanced by a modestly improved chance of triggering free spins thanks to Xtra-Bet. More impactful is the removal of the highest-paying symbol, which is a bit of a letdown, alongside a major boost to the top-end Multiplier Safe value. Where the Cannon symbol previously maxed at x100, the Multiplier Safe now reaches x500. That matters because multipliers can dramatically shape a bonus outcome, especially since they now feed into King of the Streets’ new persistent total multiplier, which boosts Coin wins as well as cluster wins. This Gates of Olympus-style layer creates a clear separation between the two games’ bonus rounds—so much so that returning to Coins and Cannons might feel difficult after trying this. That said, the fact that Coins don’t accumulate during standard free spins in King of the Streets could be the deciding detail for some players.

On top of that, some will likely question the choice to keep the winning potential unchanged at 15,000x the bet. With the extra punch from larger multipliers and the total multiplier mechanic, it would be reasonable to expect King of the Streets to push beyond its predecessor’s ceiling. Apparently not. Even so, King of the Streets still stands out as a lively follow-up that takes an already strong slot and piles on plenty of appealing extras.
