Zombie Circus (Relax Gaming) Slot Review

Zombie Circus: Slot Overview
Zombie Circus is a horror-themed video slot developed by Relax Gaming and released on October 24, 2018. The game draws players into a macabre circus setting where undead performers shuffle across the screen amid blood splatters and claw marks, blending carnival aesthetics with zombie folklore origins from Haitian Vodou traditions popularized in Western media. It features a classic 5-reel, 3-row layout with 10 fixed paylines, appealing to fans of high-volatility slots who enjoy straightforward yet thrilling gameplay punctuated by undead hordes and big-win potential. Targeted at experienced players seeking tense sessions with the possibility of massive payouts up to 10,587x the stake, Zombie Circus delivers a compact experience focused on its unique Zombie Wave mechanic leading into Free Spins.
Design and Graphics
The visual design of Zombie Circus evokes a gritty, atmospheric big top overrun by the undead, with a dark color palette dominated by deep reds, shadowy blacks, and sickly greens that underscore the horror-circus fusion. Reels are framed by tattered circus tents and flickering spotlights, while bloodied claw marks streak across the background, enhancing the sense of chaos and impending doom. Symbols include low-paying card royals stylized with grotesque twists, such as cracked skulls and oozing wounds, alongside higher-value thematic icons like shuffling zombies, contortionist undead, acrobatic ghouls, and a menacing ringmaster zombie as the top payer.

Animations are fluid yet restrained, befitting the game’s 2018 release era: zombies lurch realistically when part of winning combinations, with subtle decay effects and blood splashes on hits. Wild symbols, appearing as dual variants, expand or substitute dynamically with eerie glows. The Bonus symbols manifest as brain-like orbs that pulse ominously before triggering features. Sound design complements the visuals with a haunting carnival tune interspersed by moans, creaks, and dramatic swells during wins, creating immersion without overwhelming the player. Overall, the aesthetic is polished and thematic, prioritizing moody horror over flashy excess, rendering crisply on desktop and mobile devices for a cohesive experience across platforms.
Gameplay Mechanics
Zombie Circus employs a standard 5×3 grid with 10 fixed paylines, where wins form by landing three or more matching symbols from left to right on adjacent reels starting from the first reel. The base game emphasizes simplicity, with all pays calculated based on the total bet and a hit frequency of 19.74%, meaning roughly one in five spins yields a winning outcome. Players adjust bets via intuitive controls, spinning manually or using autoplay with customizable loss/win limits.
Special symbols drive the action: two types of Wild symbols substitute for all standard symbols (except Bonus) and appear stacked on reels, increasing hit potential during regular play. These Wilds land frequently enough to sustain base game momentum, often forming clusters amid the zombie horde. The Bonus symbol, depicted as a glowing brain, triggers the core mechanic when three or more land anywhere on the reels simultaneously. Payouts are swift via tumbling or direct animations, with total win displays prominent. The game’s high volatility (rated 10/10) manifests in prolonged dry spells punctuated by sharp bursts, rewarding patience as symbols like the ringmaster zombie deliver up to 500x line bets for five-of-a-kind. No additional base game modifiers exist, keeping flow predictable yet tense, with reel respins absent but Wild prevalence compensating for the lean feature set.
Bonus Features
While Zombie Circus maintains a minimalist approach, its features pack punch through the innovative Zombie Wave and ensuing Free Spins. Landing 3, 4, or 5 Bonus symbols (brains) initiates the Zombie Wave, a pre-Free Spins selection mini-game. Players choose from a selection of zombies, each revealing prizes that enhance the upcoming round: options include extra Free Spins (up to 10 additional beyond the base award), or converting specific standard symbols into Wilds for the entire Free Spins duration. For instance, selecting a zombie might transform all low-paying royals or high zombies into stackable Wilds, drastically boosting win potential.

The base Free Spins trigger yields 8 spins for 3 Bonuses, 12 for 4, and 20 for 5, played on the same reels with all chosen enhancements active. During Free Spins, the two native Wilds continue appearing, synergizing with converted symbols for massive overlaps. Retriggers occur via 3+ Bonus symbols anew, appending spins and potentially reactivating the Zombie Wave for further upgrades. No multipliers or separate bonus rounds exist, but the Wild conversions create volatile cascades of wins, where full screens of upgraded symbols can approach the 10,587x max win. Feature frequency aligns with high volatility, making activations rare but high-impact, as the undead horde “infects” reels for prolonged high-value sequences.
Betting Options and Payouts
Zombie Circus accommodates a broad range with minimum bets of €0.10 and maximums up to €100 per spin, suiting casual players and high rollers alike. The RTP stands at an above-average 96.92%, returning €96.92 for every €100 wagered over theoretical long-term play. High volatility ensures infrequent but substantial payouts, evidenced by the 19.74% hit frequency and peak potential of 10,587x the bet—translating to €1,058,700 at max stake.
| Betting Parameter | Value |
|---|---|
| Min Bet | €0.10 |
| Max Bet | €100 |
| RTP | 96.92% |
| Volatility | High (10/10) |
| Hit Frequency | 19.74% |
| Max Win | 10,587x |
Payout behavior favors big hits during Free Spins, where Wild conversions amplify line pays across the 10 paylines. No progressive jackpots or buy features dilute the pure volatility-driven model, with max win probability undisclosed but aligned to extreme highs.
Conclusion
Zombie Circus excels in delivering high-stakes tension through its Zombie Wave and Wild-heavy Free Spins, bolstered by a compelling undead circus theme and impressive 10,587x max win capped by 96.92% RTP. Strengths include the innovative symbol-conversion mechanic that turns modest triggers into reel-infecting spectacles, paired with dual Wilds for base game reliability, making it a standout for volatility chasers. Weaknesses lie in its light feature roster—no respins, multipliers, or gamble options—potentially feeling sparse for players craving constant action, alongside the high variance demanding bankroll discipline. Players can test the slot risk-free using the built-in demo available on this page. Overall, Zombie Circus offers a solid, atmospheric high-volatility outing from Relax Gaming, ideal for those who relish surfing zombie hordes toward life-changing payouts amid a carnival of the damned.
