Oops Overview
They’ve gone and done it once more! That’s right, online casino game provider Shady Lady has unleashed another hit slot that everyone’s talking about, and we’re here to break down why. But don’t just take our word for it—be sure to spin the demo above, because nothing beats experiencing the gameplay firsthand to truly appreciate everything it brings to the table.
Game Introduction
Set in a shadowy government lab, likely tucked away in some deep, dark basement, Oops is a 6-reel slot with 4 rows per reel. At its heart, 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 out of control, it also shows how chaos can escalate quickly when those in charge are people who 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 certainly a modern slot in this regard. The paying symbols on the reels include four questionable scientists and a range of 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 symbols.
By The Numbers
Oops has a default RTP of 96.28%, which is quite impressive 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 little as 0.10 per spin up to 50.00 per spin, meaning you have a shot at a significant payout regardless of your stake, thanks to that 20,000x max win.
Flu-like Features
While playing Oops, there are 3 flu-like features that can trigger randomly on any spin in the base game:
- Fever: A random number of reels are filled with mystery reveal symbols.
- Cough: A random number of spots on the reel grid are 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 round, Virus symbols can appear, capable of splitting or spreading to cover multiple positions. When this happens, all Virus symbols transform 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 has become standard for all Shady Lady slots, Oops includes a feature called “The Store,” where you can purchase various features for your playing pleasure. 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 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 the loot boxes, offering a chance to trigger 1 of 9 enhanced bonuses, ranging from bronze to silver to gold. The great thing about loot boxes is that even if you don’t hit the jackpot, the average enhanced bonus outperforms the average regular bonus, so it’s a win-win situation either way.
Before You Go
If we had to pick one word to sum up Oops, it would be quirky. And the quirkiness starts before you even spin the reels—like the notecard in the background with a “your mom doesn’t work here…” message, or the “days since last incident” counter that ticks up as you spin.
Although Oops is only the third slot from Shady Lady, it’s clear they plan to do things differently than other providers, and they deserve applause for that. With so many online casino games to choose from these days, it’s refreshing to see a provider putting players first by creating games that are both fun to play and potentially lucrative. That’s what Oops is all about—tons of fun and a chance at 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.
