Reels/Paylines: 6 reels + 35 paylines

Stakes Range: 10p to £100 per spin

RTP: 96.27%

Max Win: 10,000 x bet per spin

The Rotten slot takes place on 6 reels, 5 rows and 35 fixed paylines. Landing 3, 4, 5 or 6 matching symbols from left to right, starting from reel 1, across any payline will award a winning combination.

Bets wise, Rotten follows other Hacksaw Gaming slot games with a stake range from 10p to £100 a spin. Look out for the Bet section below the reels. Use the up and down arrows to adjust your bet to suit your pocket. In the Paytable, all payouts correspond to the bet your opt for.

Non UK players have 2 more options. First is the Autoplay feature where between 10 and 1,000 autospins can be chosen along with loss and single win limits in the Advanced tab. Then you have Turbo and Super Turbo Modes for much faster spin speed. These 2 extras are not valid when playing online slots in the UK.

The Rotten RTP is 96.27% which is in line with other Hacksaw Gaming slots but importantly above the 96% online slots average. Be warned there is a 94.13% RTP version available at some UK slot sites so best check before you starting spinning.

Expect a winning combination to land every 2.97 spins as the hit frequency rate is 33.56%. In terms of volatility, it’s very high as classed as 5/5. Finally, the Rotten slot comes with 10,000 x bet max wins. Bigger wins will come from the SwitchSpins feature which triggers more frequently in the 2 free spins features.

Theme – survive the zombie apocalypse

Theme: Zombies

High Value Symbol: Clown Zombie

Compatibility: Mobile, Tablet, Desktop

rotten-slot-base-game

With a zombies theme, the Rotten slot is set in a zombie apocalypse. A popular genre in film and television series, it all began with the Night of the Living Dead film in 1968 which was directed by George A. Romero.

Back to the slot. Your aim is to survive this new reality and avoid the undead and mad scientist who created the zombies. Set in an amusement park, the visuals are creepy and terrifying with zombies in the misty backdrop. There is a piano soundtrack which adds to the intensity and atmosphere. It’s not quite as scary as the Serial slot by Nolimit City but close enough.

On the reels, you will see low value A, K, Q, J and 10 royals which pay up to 7.5 x bet (for 6 in combination). The higher value symbols are represented by 5 zombies. The Clown Zombie is the best paying symbol with 5, 10, 20 or 40 x bet awarded for 3, 4, 5 or 6 across any payline. A screen full of this symbol will pay 1,400 x bet.

There is a Zombie Hand Wild symbol which substitutes for all paying symbols. 6 wilds will pay 50 x bet. Other symbols include 3 scatters (Switch, Mad Scientist and Total Takeover) which are key to triggering the game’s bonus features.

Rotten Mobile

rotten-mobile-slot

With Hacksaw Gaming creating all their games with HTML5 technology, the Rotten slot can be played on mobile, desktop and tablet devices. Compatible with iOS, Android and Windows smartphone devices, if you’re playing on a laptop or PC, the recommended size and ratio is 1366 x 768 or 16:9.

Rotten Bonus Features

The Rotten slot has 4 bonus features. Central to the gameplay is the SwitchSpins feature where you get respins with symbols replaced by the Clown Zombie or wild. With 2 free spins features, the Total Takeover feature sees selected symbols saved progressively for more Clown Zombie or wilds.

SwitchSpins feature

The SwitchSpins feature is triggered when the Switch Scatter symbol lands anywhere on the reels. You’ll receive respins with selected symbols are replaced with either the Clown Zombie or Zombie Hand Wild symbols. With between 1 and 10 respins awarded, landing a new Switch Scatter will add more symbols that are replaced which leads to more respins.

The replace symbol and the number of SwitchSpins will be show in the top right-hand corner of the screen. In the centre of the reels, the symbols that will be replaced are shown. Once the SwitchSpins have ended, the selected replaced symbols reset.

Mad Scientist feature

The Mad Scientist feature is activated when 3 Mad Scientist Scatter symbols land simultaneously on a base game spin. With 10 free spins awarded, there is a higher chance of landing the Switch Scatter which in turns triggers the SwitchSpins feature.

Total Takeover feature

rotten-slot-total-takeover-feature

The Total Takeover feature is played when 3 Total Takeover Scatter symbols land at the same time in the base game or Mad Scientist feature. Again, 10 free spins are awarded.

Furthermore, more Switch Scatters land to activate the SwitchSpins feature. The difference is that all selected symbols to be replaced are saved progressively. This means they do not reset each time you play the SwitchSpins feature.

You can collect them all to fill the screen completely with the Clown Zombie or Zombie Hand Wild symbol. Finally, 3 Total Takeover Scatters landing will reward you with 4 extra free spins, with no limits.

Buy Bonus feature

Players outside the UK have a Buy Bonus feature. To enable, click/press the yellow Buy Bonus button located in the bottom left-hand corner of the screen. This feature allows you to purchase 4 options with the RTP changing too:

Option Description Cost RTP
Bonushunt FeatureSpins Each spin is 5 times more likely to trigger a feature 3 x bet 96.26%
Switch FeatureSpins Every spin guarantees a Switch Scatter lands 20 x bet 96.16%

Originality








Visually, the Rotten slot is brilliantly designed and ties in with modern society’s obsession with zombies and post-apocalyptic worlds. From The Walking Dead to World War Z, slot providers seem to love games that are based on flesh-eating corpses.

Central to the action is the SwitchSpins feature. Basically, you are awarded respins with selected symbols replaced with Clown Zombies or Zombie Hand Wilds. Landing more Switch Scatters will give you more respins and more symbols that are replaced.

Fill all positions with Clown Zombies for a 1,400 x bet payout. If you fill all positions wild wilds, you’ll pocket 1,750 x bet. With various respins available, the max win is achievable.

Then you have 2 free spins features. In essence, the Mad Scientist feature is like the base game but with a higher chance of triggering the SwitchSpins feature. The Total Takeover feature has much higher win potential as symbols that are replaced will be saved throughout the feature. This means more Clown Zombies or Zombie Hand Wilds.

With additional Total Takeover free spins to be won, it presents the best chance of winning the max 10,000 x bet available. Whilst Hacksaw Gaming haven’t created anything truly unique, the excellent visuals and potential to win big in the base game and 2 free spins features will make it very appealing to slots players.

If you want more zombie action, you have The Walking Dead 2 (Playtech) which is the official slot of the TV series. 1 Left Alive (4ThePlayer) comes with a very high 97% RTP rate and Cabin Crashers (Quickspin) offers 22,144 x bet max wins.

Pros
  • 10,000 x bet max wins
  • New SwitchSpins feature
  • Excellent graphics/soundtrack
Cons
  • Gameplay a little repetitive
