Oops Overview
Oops, they’ve gone and done it once more! That’s right, online casino game developer 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 diving in, be sure to test a few spins on the demo above—nothing beats experiencing this game firsthand to grasp everything it brings to the table.
Game Introduction
Set in a shadowy government lab, likely tucked away in a deep, dark basement, Oops is a 6-reel slot with 4 rows per reel. At its core, this game spins a tale of how things can go horribly wrong when lab experiments are 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 folks who probably shouldn’t be running anything at all.
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 definitely a modern slot in this respect. The paying symbols on the reels include four dubious scientists and various accessories like a syringe, underwear (yes, underwear!), a sandwich, a glove, and even some footwear to boot (pun 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 highly volatile game (rated 10 out of 10 by Shady Lady themselves) with a maximum win of a whopping 20,000x your bet. Bet sizes on Oops range from as low as 0.10 per spin up to 50.00 per spin, meaning you have a shot at a substantial payout regardless of your wager, thanks to that 20,000x max win.
Flu-like Features
While spinning 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 across 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 kicks off the Pandemic free spins. During this 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 splitting or spreading depends on their mutation level (there are 5 mutation levels total). To raise the mutation level, collect 3 mutation symbols, which also grants 3 additional free spins.
The Store
As is now 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 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 in one go, keeping the 3 highest-paying results from all 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, offering 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 beats 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 even before you spin the reels. Case in point: the notecard in the background with a “your mom doesn’t work here…” message! Plus, there’s the “days since last incident” counter that ticks up as you spin.
Though Oops is only the third slot from Shady Lady, it’s clear they aim to do things differently from 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 with the chance for impressive wins. If you haven’t yet, be sure to try the demo at the top of this page to see for yourself what the buzz is about.
