Helloween Review

Look and Feel

Helloween is an October 2020 online slot release from Play’n GO. Although this spooky slot was released a couple of weeks before Halloween, it is perhaps not what you expect it to be. While it is true that Helloween is a portmanteau of ‘Hell’ and ‘Halloween’, there is more to this slot than meets the eye … or rather the ear.

This is another in Play’n GO’s bizarre series of slots based on slightly-obscure rock bands, following on from their last two releases in this series Saxon and Twisted Sister. ‘Helloween’ are German power metal band from Hamburg, formed in 1984. Despite being around for over a quarter of a century three of the founding members of Helloween are still with the band, with the fourth – drummer Ingo Schwichtenberg – having committed suicide in 1995.

The band have released 15 studio albums so far but have tasted little success outside of their native land, although they are very popular in Japan too. Their most successful album – Keeper of the Seven Keys – was a hit in the US and UK, but that was in the late 1980s. That album is actually referenced in this slots game, which you will find out about if you keep on reading!


This game does not come with any kind of progressive jackpot. A powerful jackpot can be yours though if good fortune falls into your lap – up to 50,000 times the value of your stake.

Play for Real Money

If you are in the UK and play this slots game at a UKGC-licensed casino then you will not be able to play it for play money or for free. You can of course play this game for real money at a number of online casinos, including Slots Million. This site does not actually have one million slots, but it does have a high number plus decent bonuses, so go check them out.


You can start rocking with this slot as soon as you have selected your bet size. The size of your wager can be anything from £0.10 to £100. There are ten paylines, so every spin will cost you ten coins.

Nothing hellish here about the way you secure wins – just land three or more symbols on a payline from the left-hand reel onwards. Wins are paid out as coins in line with the table below:

A cloud of spinning keys acts as the scatter in this game. They are wild too – substituting for all other symbols. You need to land three scatters anywhere on the reels to trigger the ‘Keeper of the Seven Keys’ feature. There are several different features within this one feature, and each triggers five free spins:

  • I’m Alive: All wilds that land become sticky but move up or down one row on each spin
  • Future World: All wilds that land expand to fill the whole reel
  • Eagle Fly Free: A wild is placed on the reels for every spin but then changes position with every following spin
  • Dr Stein: A ‘playing card’ symbol is chosen at random and all instances of that symbol become wild
  • March of Time: All wilds become walking wilds, moving on reel to the left on each spin
  • I Want Out: Wilds on the reels become 2×2 wilds
  • Helloween Free Spins: You are awarded seven free spins as opposed to five. If you land another three scatters during these spins then Helloween free spins are retriggered.

A Helloween multiplier may be awarded after any feature. This is a win multiplier between x2 and x10. Each feature (except Helloween Free Spins) also has its own version of the wild symbol. Land five wilds on a payline to win 3,000 times the value of your bet.

If you haven’t worked it out – all the features (aside from Helloween Free Spins) are named after Helloween tracks on ‘Keeper of the Seven Keys’.

Graphics and Sounds

It will not surprise you to learn that there’s a pretty rocking soundtrack to this Play’n GO slot. That’s because the background music is supplied by Helloween themselves. Unfortunately we are not big fans of Helloween (and who is?) so we don’t know which song they are playing in the background. The rest of the sounds are the clicks and rolling of the reels.

The graphics fit in well with the nightmarish feel of this game. There are virtually static though, although the scatter symbol looks really cool though with those spinning keys. When it comes to the bonus feature, a spinning, seven-pointed star appears and spins to decide which feature you are going to be awarded. That does look especially fab.


And so it goes on … as part of their ‘fifty-two new online slots in 2020’ pledge, Play’n GO have released yet another online slot, and another that’s in line with their ‘slightly obscure rock bands’ motif. One of our more ‘mature’ rockers here at JustSlots admitted that they had heard of Helloween, but had assumed they had broken up years ago.

Whether you love, like, don’t like or haven’t even heard of Helloween doesn’t really matter here. This is a very nice game and the number and randomness of the features should appeal to most slots players. The music though is likely only to appeal to power rock fans, but thankfully it can be muted!

Why not say hello to Helloween at one of our many recommend online casinos?
