Upon opening this Rotten sweepstakes slot machine we immediately get the chills. Seeing the zombies reminded us of the zombie series The Walking Dead.

Whether this sweepstakes slot machine will be as much of a hit as this series remains to be seen. After all, there are already quite a few horror slots out there. Unfortunately, most of them did not achieve a high score in the past.

Theme and storyline

Rotten has a horror theme and, oddly enough, takes place at a fairground. It doesn’t look very cozy at this fairground. You see some shadows of zombies and the carousel and Ferris wheel look like they could fall apart from misery at any moment. We think the design is just ok and the workmanship could have been a bit higher quality.

What we find strongest is the soundtrack. It sends shivers down our spines and creates a nice tension with each spin. We do have a slight feeling that this is copied from NetEnt’s popular Blood Suckers slot machine.

Rotten Slot – Theme (basegame)


Rotten has a number of nice features that can provide extra entertainment and variety. There is, of course, a wild symbol that in the form of a skeleton can substitute for other regular symbols in a combination.

Even without other symbols, wilds can provide nice prizes. A combination of 6 wild symbols is good for 50 times the bet.


The switchspins feature can become active both in the base game and during one of the free spins rounds. Spinning the switch symbol assigns a random number of respins between 1 and 10. Before the switch spins start, a symbol is first selected to be replaced by wilds or the most valuable of the terrifying clowns.

During the respins, you can earn additional respins by spinning an additional switch symbol. Another additional symbol will also be selected to be replaced by a valuable or wild symbol. Above the playfield during the switch spins feature you can see which symbols are currently being substituted and for which symbols.

Rotten free spins

Rotten features no less than two free spins rounds: the mad scientist bonus round and the total takeover bonus round.

To earn access the mad scientist free spins you must spin 3 or more mad scientist scatters. This will then earn you 10 mad scientist free spins. This bonus round is very similar to the base game of Rotten but the chances of aciting the switch spins are a lot higher. Of course, the other big difference from the base game is that the spins don’t cost you a penny.

The total takeover free spins round differs a bit more from the base game than the mad scientist spins. By the way, also for the total takeover free spins, you need 3 scatters to earn 10 free spins.

The probability of switch symbols is also higher in the total takeover free spins, the symbols that are substituted remain during this bonus round. This means that they are not reset after the switch respins have taken place. You can also earn 4 additional total takeover free spins by spinning another 3 total takeover scatters.
