Oops Overview

They’ve 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 you dive in, make sure to spin the demo above—there’s no better way to experience everything this game brings to the table firsthand.

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 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 fast when those in charge are people who really shouldn’t be running 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 definitely a 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 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 kind. It’s a high-volatility game (rated 10 out of 10 by Shady Lady themselves) with a maximum win of a massive 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 impressive wins regardless of your wager, 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 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 turn 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 kicks off the Pandemic free spins. During the bonus round, Virus symbols can appear, and they have the ability to split or spread across multiple positions. When this happens, all Virus symbols transform into the same paying symbol. How much they split or spread depends on their mutation level (there are 5 levels total). To raise the mutation level, you need to collect 3 mutation symbols, which also awards 3 extra free spins.

The Store

As has become standard for all Shady Lady slots, Oops includes a feature called “The Store,” where you can buy various features for your enjoyment. First, you can purchase bonus boosters to increase your chances of triggering the bonus round, or you can jump straight into the bonus round with a bonus buy. The 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 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 shot at triggering 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 that quirkiness starts before you even spin. Case in point: 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 each spin.

Although Oops is only the third slot from Shady Lady, it’s clear they’re doing things differently than other providers, and they deserve credit for that. 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 about: a ton of fun with the chance for impressive wins. If you haven’t already, try the demo at the top of this page to see for yourself.
