Today we’re reviewing an exciting new release from the provider Win Fast – the Virus Mania slot.


The theme of viruses and infections has remained relevant in the gaming industry for over 10 years. Just remember the once-popular slot Cyrus the Virus, which was released back in 2015 and gained phenomenal popularity among gambling enthusiasts. The global outbreak of COVID-19 only added fuel to the fire, becoming a true trigger for creators of blockbuster movies, animated series, and video games featuring characters engaged in relentless battles against parasites. Characters like Virus Bacteria from Space Rangers, Captain Virus from the educational cartoon of the same name, and various Zombie Viruses have all gained popularity.
Virus Mania slot
It’s definitely a hot and timely topic, and the well-known Japanese software developer Win Fast decided not to stay on the sidelines, releasing an online slot machine called Virus Mania slot. The new game was launched very recently and has already sparked great interest in the gambling world. The slot is created in the best traditions of cartoon-style games. It features a vibrant design with amusing drop-down symbols in the form of viruses of various shapes and colors, a fantastic antiviral device, and a determined female virologist armed with a blaster.


The overall atmosphere of the game is cheerful and energetic, filled with dynamism, action, and upbeat music.
Distinctive Features and Fun Highlights of the Slot

A breeding ground of viruses, contagious fun, and intense thrills — Virus Mania is made up of 6 cascading reels with an impressive win potential of up to 5000x. From the very first moments, the slot immerses you in a vibrant atmosphere full of energy, excitement, and action. WILD symbols, infectious viral cascades, and a FREE SPIN bonus mode with adjustable multipliers — all of this makes Virus Mania a truly “wild” slot packed with unpredictable adventures. It’s the perfect choice for thrill-seeking gamblers who crave non-stop action. But let’s take it step by step…
Base Game of Virus Mania

The main game mechanic involves the simultaneous and sequential spinning of six reels with various symbols that fall randomly in "infectious cascades" from the top, filling the cells of the game grid. As in most online slot machines that follow modern slot development trends, Virus Mania by provider Win Fast features 4 types of symbols:
-
Low-value viruses: 6 types of symbols with smaller payouts.
-
High-value viruses: 3 types of symbols with bigger payouts.
-
Wild symbols: (WILD) substitute for all regular symbols to help create winning combinations.
-
Scatter symbols: (Scatters) trigger the bonus game and free spins.
On the game grid, the symbols appear as follows:
Low-Value Symbols

High-Value Symbols

WILD Symbols

Scatter Symbols in the form of the logo

When a cluster of eight or more identical symbols appears, it is considered a winning combination. Identical virus symbols are counted across the entire game grid, regardless of where they land. The player receives a payout, after which the matching symbols disappear from the grid. The remaining "viruses" drop down the reels, and the empty spaces are filled with new symbols falling randomly from above. If another winning combination appears, the process repeats.

Such a “chain reaction” continues automatically without the player’s involvement until there are no more winning combinations on the grid. Once the process stops, the player launches the cascading reels again and waits for 8 or more identical viruses to match.
How Do WILDS and the Multiplier Work?

The game gains a powerful new impulse when Wilds appear on the grid. Dropping Wild symbols can substitute for any regular virus symbols except Scatters. The most anticipated moment in this “viral” online slot is when Wild symbols with multipliers land on the grid. These are added to the global multiplier — as if they’re infecting it — making it grow even more.
It’s important to understand that the multiplier is applied only when a winning combination includes one or more Wild symbols. Naturally, the more Wilds that appear, the more multipliers will be added to the payout amount. And one more key point — during free spins, all winnings are accumulated and saved until the feature ends.
The conclusion is obvious: it’s safe to say that the multiplier is always something to look forward to in this slot, as it plays a crucial role in achieving big wins.
Special Viral Symbols in the Slot

Another exciting feature in the Virus Mania game is the presence of special viral symbols. These differ from regular ones not only in appearance but also in functionality. When they land on the reels, these creepy characters collect Wilds outside the grid. The stored Wild symbols are released during the next cascade, adding even more unpredictability, surprise, intrigue, and excitement.
In other words, winning payouts from the three special virus types, along with regular Wilds or multiplier Wilds, are added to the reels.

Payout Sizes
The exact payout amounts depend on the types of symbols and the number of them in a winning combination. Players also receive payouts when 4 or more Scatter symbols appear on the game grid.
The payout table is as follows:

Bonus Games in Virus Mania
To activate the Free Spin (FS) mode, 4 or more Scatter symbols must land on the game grid. These symbols trigger the infection of bonus spins.


The total number of bonus spins depends on the number of Free Spin symbols landed at the same time.
The more of them appear on the grid, the more free spins are awarded during the bonus game.
Free Spins Table Based on the Number of Scatter Symbols:
SCATTER Symbols | Free Spins |
---|---|
1 | 4 |
4 | 10 |
5 | 12 |
6 | 14 |
8 | 18 |
9–30 | 20 |
During the bonus game, each time a Scatter symbol appears, the number of remaining free spins increases by 1.

Bonus Buy Feature in the Slot
For those who prefer more thrill, the slot machine offers the option to purchase bonus games. In practice, this means buying free spins with an adjustable bet amount. This approach makes the feature accessible to a wide range of players — both high rollers and those who play more cautiously. To access the bonus buy option, the player needs to click a special activation button located in the bottom-left corner of the slot interface.

In the newly opened Virus Mania game window, you can set the parameters for the bonus game.

Essentially, the ability to purchase bonus spins significantly increases your chances of winning. This approach saves time — it's one thing to wait in the base game for 4 bonus Scatters to land, and quite another to buy them at any convenient moment. Additionally, having extra spins allows for better bet planning and more effective bankroll management. And of course, playing with additional spins makes the gameplay even more emotional and engaging, as volatility is very high and the chances of winning big are much greater. You find yourself expecting a win almost every moment.
I personally tested the slot at different multiplier levels and can confidently say that the chances of winning — both with purchased free spins and in the base game — are quite high. As proof, I’m sharing a screenshot (WIN €3600).

Testing Results:
Virus Mania by Win Fast deserves a high rating — 8.8 out of 10. During demo mode and sessions with purchased bonuses, the slot displayed high volatility, just as the developer claimed. This means wins are less frequent, but more significant — with a €2 bet, I hit x1800 (screenshot provided above), confirming the slot’s real winning potential.
