Oops Overview
Oops, they did it again! That’s right, online casino game provider Shady Lady has rolled out another hit slot that players can’t stop talking about, and we’re here to break down why. But before you dive in, make sure to try a few spins on the demo above—there’s no better way to get a true feel for everything this game offers than by playing it firsthand.
Game Introduction
Set in a mysterious government lab, likely tucked away in a dark basement, Oops is a 6-reel slot with 4 rows per reel. At its core, the game tells the tale of what happens when lab experiments go terribly wrong thanks to careless handlers. And when things inevitably spiral out of control, it shows how chaos can escalate fast when the people in charge really shouldn’t be in charge of anything at all.
Paying Symbols
With a total of 4,096 ways to win in the base game—which can expand to an impressive 262,144 ways to win during the bonus round—Oops is a thoroughly modern slot in this regard. The paying symbols on the reels include four questionable scientists and a mix of 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 3x your bet for landing 6 of the highest-paying ones.
By The Numbers
Oops comes with a default RTP of 96.28%, which is quite 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 wager, thanks to that 20,000x max win.
Flu-like Features
While playing Oops, you’ll encounter 3 flu-like features that 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 fill with mystery reveal symbols.
- Congestion: A cluster of mystery reveal symbols is randomly added to the grid.
When any of these features activate, 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, you need to land 3 or more rat symbols anywhere on the reels, which activates the Pandemic free spins. During the bonus round, Virus symbols can appear and split or spread to cover multiple positions. When this 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 increase the mutation level, you need to collect 3 mutation symbols, which also awards 3 additional free spins.
The Store
As is standard for all Shady Lady slots, Oops includes “The Store,” where you can purchase various features for your convenience. First, you can buy bonus boosters to increase your chances of triggering the bonus round, or jump straight into it with a bonus buy. Costs are 1.5x your bet for a bonus boost, 5x your bet for a big bonus boost, or 89x your 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 chance to trigger 1 of 9 enhanced bonuses, ranging from bronze to silver to gold. Even if you don’t hit the jackpot, the average enhanced bonus outperforms the 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 the quirkiness starts before you even spin—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 every spin.
Though Oops is only the third slot from Shady Lady, it’s clear they’re set on doing things differently from other providers—and they deserve applause for that. With so many online casino games out there, it’s refreshing to see a developer putting players first by creating slots that are not only fun to play but also have serious winning potential. That’s what Oops is all about: tons of fun and the chance to score some impressive wins. If you haven’t already, give the demo a try at the top of this page to see for yourself what the buzz is about.
