Oops Overview
Oops, they’ve done it again! That’s right, online casino game provider Shady Lady has rolled out another hit title that players can’t stop talking about, and we’re here to break down why. But before diving in, be sure to test a few spins on the demo above—there’s no better way to get a real feel for everything this slot offers than by trying it firsthand.
Game Introduction
Set in a mysterious government lab—likely a dark, dingy basement—Oops is a 6-reel slot with 4 rows per reel. At its core, this game tells the tale of how experiments can go horribly wrong when left in the hands of the careless. And when things inevitably spiral, it also shows how chaos can escalate fast when those in charge are people who probably shouldn’t be running anything at all.
Paying Symbols
With 4,096 ways to win in the base game, expanding to an impressive 262,144 ways to win during the bonus round, Oops is definitely a modern slot in this regard. The paying symbols on the reels include four questionable scientists and various accessories like a syringe, underwear (yes, underwear!), a sandwich, a glove, and even some footwear (pun intended). Payouts range from 0.1x your bet for landing 3 of the lowest-paying symbols up to 3.0x your bet for landing 6 of the highest-paying ones.
By The Numbers
Oops boasts a default RTP of 96.28%, which is solid for a slot of this caliber. It’s a highly volatile game (rated 10 out of 10 by Shady Lady) with a maximum win of a whopping 20,000x your bet. Bet sizes range from as low as 0.10 per spin up to 50.00 per spin, meaning you have a shot at impressive payouts regardless of your stake, thanks to that 20,000x max win.
Flu-like Features
While playing Oops, three flu-like features can trigger randomly on any spin in the base game:
- Fever: A random number of reels fill with mystery reveal symbols.
- Cough: A random number of spots on the grid get mystery reveal symbols.
- Congestion: A cluster of mystery reveal symbols is randomly added to the grid.
When any flu-like feature hits, all mystery reveal symbols transform into the same paying symbol on the reels.
Free Spins Bonus Round
To trigger the free spins bonus round in Oops, land 3 or more rat symbols anywhere on the reels, which activates the Pandemic free spins. During this round, Virus symbols can appear, splitting or spreading to cover multiple positions. When that happens, all Virus symbols turn into the same paying symbol. How much they split or spread depends on their mutation level (there are 5 levels total). To boost the mutation level, collect 3 mutation symbols, which also awards 3 extra free spins.
The Store
As is standard for all Shady Lady slots, Oops includes a feature called “The Store,” letting you buy various perks for your gameplay. First, you can purchase bonus boosters to increase your chance of triggering the bonus round, or jump straight into it with a bonus buy. Costs are 1.5x bet for a bonus boost, 5x bet for a big bonus boost, or 89x bet for a bonus buy.
Next up are the highlight reels, which let you buy a batch of spins and keep the 3 highest-paying results. For 75x your bet, you get the top 3 results from 100 spins. For 190x your bet, it’s the top 3 from 300 spins. And for 292x your bet, you keep the top 3 from 500 spins.
Finally, there are loot boxes, giving you a shot at triggering 1 of 9 enhanced bonuses, ranging from bronze to silver to gold. Even if you don’t hit the jackpot, the average enhanced bonus beats the average regular one, so it’s a win-win either way.
Before You Go
If we had to sum up Oops in one word, it would be “quirky.” And that quirkiness starts before you even spin the reels—check out the notecard in the background with a “your mom doesn’t work here…” message, plus the “days since last incident” counter that ticks up with each spin.
Though Oops is only the third slot from Shady Lady, it’s clear they’re doing things differently from other providers, and they deserve applause for that. With so many casino games out there, it’s refreshing to see a provider putting players first by creating slots that are both fun to play and potentially very rewarding. That’s what Oops is all about—tons of fun with a chance for impressive wins. If you haven’t yet, try the demo at the top of this page to see for yourself what the buzz is about.
