King of the Streets Slot Review

King of the Streets Slot Review

Slotmill’s King of the Streets drops me straight into a smoky 1920s back alley, with Don Corlion leaning on the side of a 6x6 grid and eyeing every spin. It is a cluster pays slot where wins need at least five matching symbols connected horizontally or vertically. The tone is pure gangster noir, but the gameplay is modern, high volatility stuff backed by a 96.04% RTP and 15,000x max win potential.

When I first sat down with King of the Streets, it felt like a natural evolution of Slotmill’s cluster line-up rather than a radical shift. The avalanching grid, coin prizes and chunky multipliers create a rhythm that rewards patience. This is not a gentle slot; the swingy nature of the maths means long quiet spells, but when the Coins and Safes line up, the game can explode into life very quickly.

King of the Streets Slot Information

King of the Streets runs on a 6-reel, 6-row layout with cluster pays, so there are no fixed paylines to worry about. Stakes start at 0.20 and go up to 50 per spin, with a default RTP of 96.04% and a lower 94.20% setting available at some sites. Volatility is firmly on the high side, and the game is capped at wins of 15,000x your bet.

King of the Streets Symbols and Paytable

On the symbol front, King of the Streets keeps things familiar. The low pays are card suits – diamonds, clubs, hearts and spades. In clusters of 14 or more, they award between 6x and 9x your stake, while smaller clusters from five upwards pay scaled-down amounts. Because this is a cluster slot, you can land multiple separate groups on the same drop, and those values stack together before cascades kick in.

The premium end of King of the Streets features a pistol, cigar, whisky glass, brass knuckles and Don Corlion himself. Hit clusters of 14+ premiums and you are looking at 12x up to 50x the bet, so lining up several groups in one avalanche can snowball very quickly. A police badge acts as the Wild, substituting standard symbols, while Coins, Safes and Bonus icons bring in instant prizes, multipliers and entry into features.

Base Game & Features in King of the Streets

In the base game, King of the Streets relies on Avalanches to keep things moving. Any winning cluster is removed from the 6x6 grid along with all non-winning copies of those same symbols, creating large gaps. Before new symbols drop in from above, at least one Wild is spawned in a random empty spot, which is a neat touch that often helps create a second, third or even fourth wave of connecting clusters.

The Coin Cluster feature in King of the Streets can swing a session on its own. Coins land showing values from 1x to 40x your bet. When at least five connect in a cluster, their values are totalled and paid out, then those Coins explode and reform as a single Coin holding the combined amount. If you chain more Coins into it on later avalanches, you can get paid on that same cluster again.

Multiplier Safes round out the King of the Streets base action. Safes land displaying potential multipliers from x2 right up to x500. When you hit at least one win in a round and a Safe is present, it activates and sticks around while Avalanches continue. Once no more wins appear, all active Safes open, their multipliers are combined, and that total is applied to everything you have collected on that spin.

King of the Streets Free Spins & Bonus Features

The standard Free Spins round in King of the Streets triggers when three Bonus symbols land in a single spin, giving 10 spins out of the gate. During this mode, every Multiplier Safe that activates adds its value to a running total multiplier that never resets. Whenever a spin produces a win and at least one Safe has been triggered, that accumulated multiplier is applied. +1 symbols can drop in as well, adding extra spins.

The Super Free Spins feature in King of the Streets raises the stakes. Land two Bonus symbols and a Super Bonus to get 10 Super Free Spins where Coins behave differently. Any Coins left on the grid after wins are collected at the bottom and remain for the rest of the bonus, making it easier to form fresh Coin Clusters. If you prefer skipping the wait, the Fast Track menu offers several buy-in options at 40x, 100x and 500x.

Our Honest Verdict on King of the Streets

From my sessions, King of the Streets feels like Slotmill at their best, with sharp maths, punchy features and a theme that ties everything together. The combination of Coin Clusters, persistent multipliers in bonus play and a realistic 15,000x ceiling gives the slot proper long-term bite. It is not a game for small bankrolls or impatient moods, but when the features align, the ride is gripping and well worth the grind.
