Theme – Audio & Design Features – official slot for the German power metal band

Helloween slot base game

The Helloween slot is a Halloween themed game which is inspired by the German power metal band of the same name. Set inside a medieval looking tower, it comes with a rocking soundtrack from the band’s Keeper of the Seven Keys Part 1 and Party 2 albums.

Symbols include A, K, Q, J, 10 and 9 royals as well as creepy hands, ghouls, a mysterious sorcerer and a gold ring. The gold ring symbol is the highest paying with 3, 4 or 5 giving you 5, 10 or 20 x your total stake.

The pumpkin symbol is the wild and substitutes for all normal symbols. Paying 20 x stake for 5 in combination, there are also 6 more pumpkin wilds which appear in their own bonus feature (more details below).

As with all slots these days, Helloween can be enjoyed on all devices including smartphones and tablets. The simple 5x3 set up looks just as good on mobiles as it does on laptops or desktop screens.

Bonus Features in Helloween

The Helloween slot has a whopping 8 bonus features. Central to the action is the Keeper of the Seven Keys feature wheel which will give you access to 7 free spins features. Each offering their own pumpkin wild symbol to give you wild reels, 2x2 wilds, roaming wilds and more, there’s a random Helloween Multiplier feature which can apply a 10x multiplier to winnings.

Keeper of the Seven Keys feature wheel

The Keeper of the Seven Keys feature wheel can be accessed when landing a 7 keys scatter symbol on reels 1, 3 and 5 simultaneously. Here, the wheel spins to trigger 1 of 7 bonus features. In all features, scatters act as wild symbols. Here’s what to expect from 6 of them:

Feature Free Spins Details

Helloween Free Spins feature

In the Helloween Free Spins feature, you begin with 7 free spins. Scatter symbols appear and are collected as you play. If you collect 3, you spin the Keeper of the Seven Keys feature wheel meaning you can play 1 of the 7 bonus features.  If you get the Helloween option, you get a further 7 free spins, with no limits.

Helloween Multiplier feature

After any of the features play out, there’s a random chance you will trigger the Helloween Multiplier feature. A multiplier of 2x, 3x, 5x or 10x is applied to all winnings from that feature.

Helloween Review Summary – plenty of free spins features  

Well designed and with a rocking soundtrack, the Helloween slot has more free spins features than any other slot we’ve come across. It’s the luck of the draw from the Keeper of the Seven Keys feature wheel really.

The best feature is the Future World feature. This is because you could in theory get 5 wild reels on every free spin. However, to win big, you need the Helloween Multiplier feature to trigger. This would subject winnings to a multiplier as high as 10x.

Overall, it’s a decent slot game with lots of variety and free spins. It’s not as volatile as most Play ‘n GO titles which is a good thing. This gives you a better chance of playing all the bonus features. You just need the Helloween Multiplier to kick in really.

Play ‘n GO has developed quite a few slots based on famous rock bands. The best is the Testament slot which can give you up to 2,400 ways to win and boasts max wins of 20,000 x stake.
