Welcome to Rotten Online Slot

Rotten slot is a Hacksaw Gaming slot that is dark, innovative, and full of potential. It is based on a zombie apocalypse, and the fantastic artwork by the developers makes it stand out. If you are a fan of the shows or movies like Zombieland and The Walking Dead, you might like this slot.

Rotten introduces the SwitchSpins feature, which is a Respins feature with a twist. The base slot is exciting because of the Respins round, but the bonus game is where this feature shines. In short, they have tried to use this new feature to give you bigger rewards for playing longer.

This slot gives you 6 reels, 5 rows, and 35 paylines, which are more than enough to grant you massive wins. There are two types of Free Spins: the Mad Scientist bonus game and the Total Takeover Bonus Game. The Respins feature plays a crucial role in both types of spins, and we will explain how it works soon.

Gameplay of Rotten video slot by Hacksaw Gaming


Zombie Apocalypse Theme and Scary Design

Theme and Design

This slot takes you into a post-apocalyptic world where zombies have taken over. A mad scientist created the zombies, which have destroyed most of the world. The background at the beginning is an amusement park with zombies standing around, ready to attack any unsuspecting victims.

During the two bonus games, you will see different backgrounds. One bonus features a haunted house with a big zombie, and the other one shows an old zombie who could be the mad scientist.

Hacksaw Gaming has done a good job of telling us the story of this slot through the backgrounds shown in the features. Furthermore, the background music is a little intense but also very enjoyable.


The higher-paying symbols are the character symbols, with the clown zombie being the highest-paying symbol. The high-paying symbols will pay you 15x to 40x of your bet for landing a six-of-a-kind winning combination. On the other hand, the low-pay symbols are cards that pay 2.5x to 7.5x of your bet for landing six-of-a-kind winning combinations.

The Wild symbol is the hand of a zombie, and the Scatters feature the mad scientist and a scary zombie.

Fantastic Bonus Features

The SwitchSpins, Mad Scientist Free Spins, Total Takeover Free Spins, and Bonus Buy feature are the bonuses you will get in this feature-rich casino game. Let us help you understand how you can win through these features now.

SwitchSpins Feature

Whenever the Switch Scatter symbol lands on the reels, the SwitchSpins begin. In this bonus, you will get 1 to 10 Respins, where certain randomly selected symbols will be replaced by either the game’s highest-paying symbol or Wild symbol. Landing Switch symbols during the Respins will award additional Respins and start replacing more symbols.

You can clearly see how many Respins are left on the top right, and the symbols chosen to be replaced are shown on the top of the grid. The selected replaced symbols reset after the bonus ends, and you get a new set of symbols when you trigger it again.

Mad Scientist Free Spins

Three Mad Scientist Scatter symbols are required to trigger this free spins bonus game with ten Free Spins. Your chances of landing the Switch symbol are much higher compared to the base game. This feature can be upgraded to the Total Takeover bonus by landing 3 Total Takeover symbols simultaneously.

Total Takeover Bonus Game

Three Total Takeover Scatter symbols will trigger the Total Takeover bonus with ten Free Spins. Like the other bonus, the chances of triggering SwitchSpins are higher here. The added advantage of this feature is that all symbols chosen to be replaced are saved progressively. Simply put, once a symbol is replaced, it will be replaced whenever the SwitchSpins trigger during this bonus.

If you land three Total Takeover Scatters during the bonus, you will get an additional four Free Spins.

Buy Bonus Feature

This feature will give you the following options that you can buy instantly:

  • Bonushunt FeatureSpins (very high volatility and 96.26% RTP): It triples your bet and gives you a 5 times higher chance of triggering bonus games.
