From the depths of a disastrously mismanaged laboratory comes Oops, a chaotic and satirical slot from developer Shady Lady. This high-volatility title takes players into a world where scientific errors have gone unchecked, unleashing viral madness and global panic — all wrapped in slapstick humor and innovative game mechanics.

Disaster strikes, but it pays:

Set in a crumbling research facility operated by well-meaning but clumsy scientists, Oops brings a comedic twist to the idea of biohazards and human failure. Players spin on a 6×4 grid that starts with 4,096 ways to win and can expand up to a staggering 262,144 ways during free spins. The design plays off pandemic-era anxieties but filters them through colorful animations, absurd hazards, and exaggerated lab mishaps.

In a setting where containment is a running joke and the cure seems as elusive as logic, Oops invites players to trigger chaos on every spin. The game’s RTP options include 96.28%, 94.13%, or 92.01%, depending on the operator’s configuration. Volatility is rated a maximum 10 out of 10, and the top win reaches a generous 20,000x the bet, as published in the game sheet (pdf).

The game’s paytable is a collection of biohazardous curiosities. Low-paying icons include a boot, glove, sandwich, underwear, and syringe — all contaminated. High-paying symbols feature four caricatured scientists, each progressively more disheveled or outfitted in hazmat gear. Scatters come in the form of a lab rat, the key to triggering the feature-packed free spins round. Notably, Oops includes no wild symbols — likely mutated out of the equation.

On any base game spin, one of three “flu-like” features may be randomly activated, each filling the grid with mystery reveal symbols that transform into matching regular icons:

  • Fever: Between 1 and 6 full columns are slimed with mystery symbols.
  • Cough: 3 to 20 individual spots get hit with mucous-covered reveals.
  • Congestion: A 4 to 16 symbol cluster of goo settles in for the win.

These modifiers provide a quirky and thematic twist on traditional symbol reveals, each adding unique grid interaction for visual flair and potential payouts.

Pandemic Free Spins with Mutation Levels

Triggering the bonus round requires three or more Lab Rat scatters, which initially award six free spins plus one for each additional scatter. Once inside, Virus symbols begin spreading or splitting — covering adjacent tiles or duplicating themselves — before transforming into matching high-value symbols.

What sets the free spins apart is the progressive mutation system. Players collect Mutation symbols to boost the virus’s impact, increasing its number of actions per spin (from 1 to 5) and earning three additional spins at each new level.

Oops delivers a bizarre but entertaining ride that feels part dystopian satire, part chaotic bonus bonanza. With its dynamic features, over-the-top humor, and massive win potential, the game appeals to players looking for something both edgy and exciting. Whether spreading viruses or unboxing bonus boosters, Oops dares players to find order in scientific disorder — and rewards them handsomely for the risk.
