Oops Overview
They’ve gone and done it once more! That’s right, online casino game developer Shady Lady has rolled out another highly talked-about slot, and we’re here to break down why it’s creating such a buzz. But before diving in, be sure to take the demo for a spin above—there’s no better way to experience everything this game has to offer than by playing it yourself.
Game Introduction
Set in a shadowy government lab, likely tucked away in a dim, underground bunker, Oops is a 6-reel slot with 4 rows per reel. At its heart, this game tells the tale of how experiments can go disastrously wrong when left in the hands of the careless. And when things inevitably spiral out of control, it shows how chaos can escalate when those in charge are utterly unfit for the job.
Paying Symbols
Featuring 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 respect. The paying symbols on the reels include four dubious scientists and a range of odd accessories like a syringe, underwear (yes, really!), a sandwich, a glove, and even a pair of shoes (pun fully intended!). Payouts for these symbols 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 high-volatility game (rated 10 out of 10 by Shady Lady themselves) with a maximum win potential of a whopping 20,000x your bet. Bet sizes on Oops range from as little as 0.10 per spin up to 50.00 per spin, meaning you have a shot at substantial wins regardless of your stake, 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 get filled with mystery reveal symbols.
- Cough: A random number of spots on the reel grid get filled with mystery reveal symbols.
- Congestion: A cluster of mystery reveal symbols is randomly added to the reel grid.
When any of these flu-like 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 this bonus round, Virus symbols can appear on the reels, with the ability to split or spread across multiple positions. When this happens, all Virus symbols turn into the same paying symbol. The extent of the split or spread depends on their mutation level (there are 5 mutation levels in total). To increase the mutation level, you must collect 3 mutation symbols, which also awards 3 additional free spins.
The Store
As is standard for all Shady Lady slots, Oops includes a feature called “The Store,” letting you purchase various features for your enjoyment. First, you can buy bonus boosters for a higher chance of triggering the bonus round, or jump straight into the bonus round 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 in one go, keeping the 3 highest-paying results from all those spins. For 75x your bet, you keep 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 the loot boxes, which give you a chance to trigger 1 of 9 enhanced bonuses, ranging from bronze to silver to gold. What’s great about loot boxes is that even if you don’t hit the jackpot, the average enhanced bonus still outperforms the average regular bonus, 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 the reels—like the notecard in the background reading “your mom doesn’t work here…” and 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 taking a different approach than other providers, and that deserves applause. With so many casino games out there, it’s refreshing to see a developer putting players first by crafting games that are both fun to play and potentially very rewarding. That’s exactly what Oops is all about—tons of fun and the chance to score some impressive wins. If you haven’t already, be sure to try the demo at the top of this page to see for yourself what the fuss is about.
