Design and Theme
🖼️ Graphics
Visually, Helloween is well crafted: a dark grid, detailed symbols, and the signature pumpkin wild. However, the developers for some reason added concert footage — it appears both in the intro and when entering the bonus. It looks somewhat… rough, and it breaks the overall visual style.
🎶 Sound
The soundtrack is driven by Keeper of the Seven Keys — the iconic track from the band, which plays in the background and carries the atmosphere. Every spin lands against a powerful backdrop, and the bonuses are further emphasised with heavier guitar accents.

Special Symbols
- Scatter (sphere with keys): appears on reels 1, 3 and 5. With three symbols, it triggers the Keeper of the Seven Keys wheel. During the Helloween Free Spins mode, scatters can be collected again for a retrigger.
- Wild (pumpkin): in the base game, it substitutes for regular symbols and pays x20 for 5 of a kind. In bonus modes, the wild changes behaviour and pays x30 for 5 symbols.
- Helloween Multiplier: after a bonus mode ends, a random multiplier of x2, x3, x5 or x10 may be added to the win.
Bonus Game
To understand how to play Helloween, remember that three scatters on reels 1, 3 and 5 trigger the Keeper of the Seven Keys wheel. It selects one of seven modes: six “song” modes award 5 free spins, and Helloween Free Spins awards 7.
- I’m Alive: wilds stick in place and expand one position up and down each spin.
- Future World: any wild that lands expands to cover the entire reel.
- Eagle Fly Free: one extra wild appears on the grid in every spin and changes position in subsequent spins.
- Dr Stein: one of the card symbols (9–A) is selected at random, and all its instances turn into wilds.
- March of Time: wilds remain on the reels and shift left by one position each spin until they reach the first reel; after that, they disappear.
- I Want Out: wilds expand to a 2x2 size.
- Helloween Free Spins: awards 7 spins. During the feature, scatters are collected in a counter; collecting 3 scatters triggers the Keeper wheel again with a new feature and adds +7 spins. The counter then resets, and the remaining free spins continue to play out.
RTP, Volatility, Max Win
RTP — 96.20%. Volatility is high. The maximum win is capped at x5000 your stake.
Our Verdict
In the base game, the slot feels weak: wins are rare, and the balance drops visibly. Everything hinges on the bonuses — we landed March of Time and Future World, both of which returned a bit of money, but the promised multiplier didn’t trigger even once.
If you want a game with a more consistent multiplier, it’s better to try Gates of Olympus 1000. And for those who enjoy varied wild mechanics, Wild Wild West slot is a good choice, where the symbol type defines the wheel before the bonus is triggered.
