Rotten by Hacksaw Gaming – Overview and Demo

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.

Features

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.

Switchspins

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.

Stakes and Variance

How do you play the Rotten slot? Up to 30 deadly figures can land on the Rotten slot’s playfield. There are 35 ways to combine the symbols with each other. Betting is possible between $0.10 and $100 per spin.

The math behind the game is just fine. Rotten comes with different payout percentages, depending on the online casino in which you play this slot. The best payout percentage is a neat 96.27% but there are also versions with 94.13%, 92.33% or even 88.03%. So always worth taking a look at where you play!

Although the variance of the payouts in Rotten is high, on average a winning combination falls on the playfield every 3 spins. So you usually don’t have to wait very long for prizes but they generally won’t be very high. The highest possible prize in Rotten is 10,000 times the bet.

Conclusion

The theme of Rotten is something that should appeal to you. Some like horror while others don’t consider playing a game with this scary theme. On the design, Hacksaw Gaming could have done a little better. But, all in all, the combination of Walking Dead series meets Blood Suckers in terms of sound, does create a nice atmosphere.

About the gameplay of Rotten, opinions will be more unambiguous. After all, this is just fine. The game is not too complex and therefore plays smoothly and pleasantly. The statistics and design are also good which makes this slot machine score just fine across the board.
