Street Knockout: Slot Overview 

Street Knockout, developed by NowNow Gaming in collaboration with Hacksaw Gaming, bursts onto the scene with fists flying and reels tumbling. Set in a gritty back-alley fight club ambiance straight out of an urban beat-’em-up video game, the slot drops players into a 6×6 battle arena where brawlers clash in a no-holds-barred match. Released on June 24, 2025, the game adopts a cluster pays mechanic that thrives on momentum, chaining wins through cascading symbols, rising multipliers, and unique knockout mechanics. 

Thematically bold and mechanically fresh, Street Knockout offers a high-octane gaming experience with a 96.30% RTP, 28.32% hit frequency, and a satisfying maximum win of 10,000x the stake. Volatility is high, rated 4 out of 5, giving players a solid chance at meaningful payouts, especially during free spins when progressive multipliers persist. A mix of chaos, control, and combat, Street Knockout lands like a haymaker and invites players to step into the digital fight club arena.

Design and Graphics 

Street Knockout’s visual presentation mirrors its street-fighting theme perfectly. The reels are framed by a rusted metal cage, dimly lit by alleyway lamps, with the backdrop exuding urban menace and underground tension. Each symbol is styled like a character or object you’d expect in a bare-knuckle brawl narrative—ranging from street thugs and fighters to traditional playing cards stylized to match the gritty atmosphere.The interface is clear and responsive, with reel multipliers displayed above each column and the game’s logo pulsing like a neon sign in a backstreet dojo. When clusters explode or fighters get knocked out, the animations are slick and impactful, with highlighted frames, smoke bursts, and screen shakes adding dynamic intensity. 

NowNow Gaming clearly drew inspiration from arcade fighting games, giving the slot a visual identity that merges seamlessly with its gameplay. It’s not overly polished or glossy—on purpose—staying true to its urban combat aesthetic.

Gameplay Mechanics 

Street Knockout features a 6×6 reel layout with cluster pays—wins are formed by landing five or more matching symbols in vertical or horizontal adjacency. Symbols cascade following a win, allowing new ones to drop and potentially form consecutive winning combinations. 

The key gameplay element is its Knockout mechanic, which transforms the slot’s format from standard cluster play into an exciting combo-based system. During base gameplay or through bonus triggers, a random number of reel positions can be highlighted. If any fighter symbols land on these highlighted areas, they transform into wilds with attached multipliers—ranging from x1 to x10 for general symbols and up to x500 if it’s the highest-paying fighter. 

Winning combinations remove symbols from the screen, and multipliers are collected above their respective reels. These multipliers accumulate and apply to all wins involving their reel, compounding potential as the round continues.

Sound and Music 

The audio design of Street Knockout amplifies its back-alley battle vibes with a raw, industrial soundtrack. A gritty metal guitar riff loops in the background, mimicking the intensity of a street brawl, while voice samples like “Fight!” or “KO!” punctuate key events like wild transformations or big wins. 

Sound effects are punchy and direct—literally—featuring thuds, smashes, and audio spikes when clusters explode or multipliers kick in. These aren’t just cosmetic additions—they serve to build anticipation and reward, complementing the animations and reel reactions perfectly. The atmosphere is one of controlled chaos, and the audio plays a critical role in immersing the player in that energy.

Bonus Features 

Street Knockout comes armed with an impressive selection of features, designed to fuel the combo-heavy chaos that defines its identity:Knockout Wilds 

Triggered randomly during base game spins, knockout wilds occur when fighter symbols land on highlighted positions. These fighters transform into wilds with multipliers from x1 to x500, depending on the character. The resulting wilds can substitute for any symbol in a winning cluster and apply their multiplier to the win. Multipliers stack and are collected above reels, applying to subsequent wins involving that reel. 

Golden Fist 

During knockout events, the Golden Fist symbol can appear and trigger one of two effects: 

Cross Smash – Removes symbols in a horizontal and vertical line, replacing them with fresh symbols and potentially triggering new cascades. 

Low-Pay Clear – Eliminates all low-paying symbols from the board, increasing the odds of higher-value wins. 

This function adds depth to the knockout system by shaking up the board and clearing paths for larger wins. 

Power Bonus 

Landing 4, 5, or 6 scatters awards 6, 8, or 10 free spins, respectively. The highlight of the Power Bonus is that reel multipliers do not reset between spins, meaning the potential for progressive accumulation and larger payouts increases dramatically as the session progresses. Combined with wild multipliers and cascades, this bonus round can deliver knockout punches of its own. 

Bonus Buys 

Three bonus buy options are available:BonusHunt FeatureSpins (2x bet): Increases chance to trigger a bonus game by 3x. 

Knockout FeatureSpins (50x bet): Each spin includes guaranteed knockout wilds and reel multipliers between x1 and x100. 

Power Bonus Buy (100x bet): Grants immediate access to the Power Bonus with persistent multipliers. 

These allow more aggressive players to dive straight into the most lucrative parts of the game without waiting for natural triggers.

Betting Options and Payouts 

Street Knockout accommodates a wide range of budgets, with bets ranging from €0.10 to €100 per spin. This makes it accessible for both casual players and high rollers. The game offers two RTP models—96.30% and 94.34%—so it’s important to check which version your chosen casino offers. 

The max win is a solid 10,000x your stake, aligning it with other top-tier high-volatility slots. Cluster payouts start with 5-symbol clusters and can go up to 13+ symbols, rewarding from 0.1x to 100x the bet, depending on the cluster size and symbol involved. Thanks to the stacking wild multipliers, reel multipliers, and cascade system, the math model is rich in combo potential, especially during bonus rounds.
