The Oops Slot Game
Like all other slots created by Shady Lady, this new release has an exciting storyline. It sheds light on a fictional government research facility with a team of inept scientists who bungle their way through experiments they don’t comprehend.
As such, expect to find yourself inside a generally disorganised lab, with spilt chemicals, an exposed sandwich, etc. Because of ignoring the laboratory code of conduct, the inept scientists poured a suspicious green slime, which caused flu-like symptoms. Even worse, the slime affected a horde of lab mice that escaped, spiralling into a fully-fledged panic mode.
But, Oops isn’t an ominous, apocalyptic scene. Instead, it assumes a humorous display, perhaps not to put players back in the COVID distress. Even the soundtrack and effects are jovial rather than eerie.
Symbols and Payouts
The game is played on a familiar 6x4 gameboard, which features nine regular symbols. And, according to the game rules, it offers 4096 ways in the base game, which could increase up to 262,144 ways in the free spins.
A winning combination happens when 3 to 6 matching symbols appear in any position of adjacent reels, beginning from the leftmost column. Only the longest matching combination per symbol pays.
It’s also worth noting that all payout combinations, along with their corresponding prizes, are displayed in the paytable and reflect the current stake.
The low-ranking symbols in Oops include the Boot In A Glove Cover, Glove, Sandwich, Underpants, and Syringe. These pay between 0.1x and 1x the bet for three or more of the same. Then, the high-paying symbols consist of the following characters:
- Green Glasses - 0.3x, 0.5x, 0.8x, and 1.5x the bet.
- Sweaty - 0.5x, 0.7x, 1x, and 1.5x the stake.
- Bald-Head with Pink Chemical on face - 0.5x, 1x, 1.5x, and 2x the bet.
- Hamzat Suited - 1x, 1.5x, 2x, and 3x the stake.
It seems that wild symbols and pandemics don’t go hand in hand. However, the video slot features a Lab Rat scatter symbol, which can trigger the bonus round.

Oops Slot Bonus Features
As the virus mutates, spreads, and strengthens by the hour, some people may take advantage of this slot’s features. They include base game modifiers, free spins, bonus boosters, and bonus buys.
Flu-like Features
One of three Flu-like features may randomly trigger on each Oops base game. After appearing in the gameplay area, all the mystery reveal symbols transform into the same regular symbol:
- Fever - slimy mystery reveal symbols fill a random number of columns.
- Cough - the mucus mystery reveal symbols will cover random positions on the grid.
- Congestion - a cluster of gooey mystery reveal symbols covers a part of the play area.

Free Spins
Three or more scatters in Oops trigger 6 free spins, while any additional scatter awards an extra spin. Any Virus symbol spreads or splits.
If the Virus spreads, it does so to any adjacent orthogonal position that doesn’t already have a Virus symbol. However, a Virus that splits will create two copies of the same independent reel at its current position.
The number of Virus actions depends on the Mutation Level; one action happens at Level 1, two at Level 2, and so on. All the Virus symbols transform into the same normal symbol once no more Virus actions happen.
The free spins start at Mutation Level 1 up to 5. Collecting 3 Mutation symbols upgrades the level one step and awards 3 additional spins.

Bonus Boost & Bonus Buy
The Oops slot lets you increase the feature trigger chances by activating the Bonus Boost for 1.5x bet and Big Bonus Boost for 5x the stake. Meanwhile, the Bonus Buy enables you to pay 89x the bet, guaranteeing an instant entry to the free spins on your next spin!

Highlight Reels
The Highlight Reels lets you purchase 100, 300, and 500 spin batches at 75x, 190x, and 292x the bet, respectively, for the three highest-paying results. The spins are presented in an ascending win order and can include any game feature.

Loot Box
Lastly, the Loot Box awards a random prize from nine Enhanced Bonuses across Bronze, Silver, and Gold Tiers. The Loot Box types are Rare, Epic, and Legendary, going for 188x, 347x, and 574x the stake, respectively!

How to Win at Oops Slot
This video slot features 6 reels, 4 rows, and an initial 4096 ways to win. However, since each reel can split into two during the free spins, the ways can increase up to 262,144 per spin!
So, to win is like any other online slot with the same configuration. Simply, match 3 or more identical symbols on adjacent reels beginning from the leftmost reel to the right. The identical symbols can be in any position as long as they are on connected reels.
To gamble a single Oops round, your budget must accommodate the €0.10 to €50 betting range.
Choose an ideal amount, and then press the Spin button to start one game round. But for autoplay, press the respective button and preselect a desired number of rounds. For the record, the game also supports fast-play mode, which can be accessed using the Turbo option.

Oops Slot RTP & Volatility
The Shady Lady has once again allowed casinos to set their preferred return-to-player (RTP) rates. So, it can be 96.01%, 94.13%, or 96.28%. Then, the volatility is high, and the win cap is 20,000 times the bet.
The Final Thoughts
I assume Shady Lady didn’t come to play, and that’s why the new and upcoming game developer has released back-to-back games. The company started with Devil’s Finger, then Brainwashed, and has now created Oops!
The level of this slot’s design is the same as that of its predecessors—meticulous and immersive. And, although it touched a sensitive nerve of the world healing from a pandemic that threatened humanity, the design team made it more witty than eerie.
Nevertheless, this latest creation didn’t come close to the first two releases, especially considering it didn’t have plenty of action going on. This time, players only get base game features and free spins with bonus boost and buy options. Even so, they were enough to set you up for the 20,000x win cap possibility, which is lucrative!
Ultimately, I believe this game continues the strong legacy established by its predecessors, solidifying the developer’s trajectory to become one of the industry’s top-ranked names. Hence, Oops is a must-try!
