Oops Overview

They’ve done it once more! That’s right, online casino game developer 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, make sure to take the demo for a spin above—there’s no better way to experience everything this slot has to offer than by trying it yourself.

Game Overview

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 heart, this game explores how experiments can go disastrously wrong when left in the hands of the careless. And when things inevitably spiral, it shows how chaos escalates when those in charge are the last people who should be running anything at all.

Paying Symbols

With 4,096 ways to win in the base game, which can expand to a massive 262,144 ways to win during the bonus round, Oops is undeniably a modern slot in this regard. The paying symbols on the reels include four questionable scientists and various accessories like a syringe, underwear (yes, you read that right—underwear!), a sandwich, a glove, and even a pair of footwear (pun fully intended!). Payouts range from 0.1x your bet for landing three of the lowest-paying symbols up to 3x your bet for six of the highest-paying ones.

By the Numbers

Oops boasts a default RTP of 96.28%, which is quite impressive for a slot of its kind. It’s a high-volatility game (rated 10 out of 10 by Shady Lady themselves) with a maximum win of a whopping 20,000x your bet. Bet sizes range from as little 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 playing Oops, three flu-like features can trigger randomly on any spin during 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 are filled with mystery reveal symbols.
  • Congestion: A cluster of mystery reveal symbols is randomly added to the reel grid.

When any flu-like feature activates, 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 three or more rat symbols anywhere on the reels, which activates the Pandemic free spins. During this round, Virus symbols can appear on the reels, capable of splitting or spreading to cover 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 five levels total). To increase the mutation level, you must collect three mutation symbols, which also awards three 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. 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 three highest-paying results. For 75x your bet, you keep the top three results from 100 spins. For 190x your bet, it’s the top three from 300 spins. And for 292x your bet, you keep the top three from 500 spins.

Finally, there are loot boxes, offering a chance to trigger one of nine 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 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 each spin.

Although 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 today, it’s refreshing to see a developer putting players first by creating games that are both fun to play and potentially very rewarding. That’s exactly what Oops is about: loads of fun and the chance for 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 all about.
