Our verdict on Helloween – 8.4/10
We had lots of fun playing the Helloween slot demo, although we had a hard time triggering all of the bonus features. With 7 different game modes, the slot has an impressive lifespan. We especially liked the “I Want Out” mode, which creates tons of winning ways. The gameplay is pretty balanced, with a solid 96.20% RTP and medium volatility, yet still a nice maximum win of 5,000x.
Since we had some trouble triggering the Keeper of the Seven Keys feature, we would have enjoyed some more action during the base game. But overall, we would still recommend this slot to most players, especially fans of the Helloween band, and spooky season enjoyers!

5 reasons to play Helloween
We tested Helloween for a while and these are our top five reasons to give this game a try:
- Keeper of the Seven Keys Feature: This slot isn’t satisfied with just a simple free spin feature. It offers 7 bonus modes, mixing lots of Wilds with different effects and their own rules. Each one of those is there to help you get to the highest payout possible.
- Free Spins: The most basic bonus mode out of the 7 offered by Helloween, but one that is quite easy to retrigger. Just land at least 3 more scatters throughout your spins and you’ll get some more rounds to play with.
- Multipliers: After each feature, a multiplier can be applied to your wins. It can only go up to 10x, but it’s still the perfect way of wrapping up an already rewarding bonus game. It makes it easier to reach the 5,000x max win.
- 5,000x Max Win: We talked about how all the features are there to help players earn up to 5,000x their bets, but we haven’t mentioned how nice that kind of payout is, especially for a medium volatility slot. That kind of win usually comes with higher variance!
- Perfect Soundtrack for Metalheads: It’s pretty obvious if you’re familiar with their music, but this slot was made as a partnership with the German metal band Helloween. It’s only natural that their music would blast during the entirety of your gameplay, giving it a whole new vibe.

How to play the Helloween Slot?
During the base rounds, Helloween’s gameplay is pretty straightforward: land at least 3 matching symbols in consecutive reels to earn a payout. The variety of bonus features really is what makes this game stand out from many other slots. Before diving into these bonus modes and the game’s symbols, let’s take a look at how its gameplay goes.
Step-by-Step Gameplay
- Launch our Helloween slot demo, or play it for real at one of the best online slots sites for UK players.
- Place your bets, ranging from £0.20 to £5.
- Spin the reels, look out for wins and the Seven Keys feature.
- Go through any bonus feature you might have triggered, and enjoy the music!
- Once everything is settled, your wins are collected, and the round ends.
- You can now adjust your bets (if necessary) and start spinning again.
Symbols & Bonus Features
During the base game, reels are filled with low-paying card symbols (from 9 to Ace) giving out a max win of 2.50 for 5 of a kind in one of the 10 paylines. Then there are demon hands, ghouls, fortune tellers and rings, with the latter paying out a maximum of 20x your bet. The pumpkin wild replaces any symbol in order to create a win, and the Seven Keys scatter triggers the Keeper of the Seven Keys feature.
When you unlock the feature, you’re taken to a bonus wheel where you’ll land on one of seven features, unlocking 5 spins and a modifier. Each modifier (except for the last one) is named after one of Helloween’s most famous songs:
- I’m Alive: Wilds landing on your reels stay there, and expand one position up or down after each spin.
- Future World: Wilds expand to fill an entire reel.
- Eagle Fly Free: A new Wild fly onto the reels before each spin, then fly over to a new position after each spin.
- Dr. Stein: On each spin, a symbol is chosen, and all its entities on the reels are changed into a Wild.
- March of Time: Each Wild walks one position to the left after every spin, until it leaves the reels.
- I Want Out: Wilds landing on the reels explode and expand to a 2×2 Wild, creating more win possibilities.
- Free spins: You might unlock 7 classic free spins which can be retriggered if you land 3 additional scatters during those rounds.
After each one of those features, a multiplier might be applied to your wins. It can be 2x, 3x, 5x, or 10x, getting you closer to the 5,000x max win available on Helloween.
Visuals and theme
Helloween by Play’n GO brings the legendary German metal band to life in a slot that’s every bit as theatrical as their music. Set against a dark fantasy backdrop, the reels are framed by gothic arches and glowing symbols, echoing the band’s unmistakable stage presence. Each high-value icon represents one of Helloween’s classic tracks, with powerful animations and fiery transitions amplifying the concert atmosphere. The soundtrack, featuring snippets from their greatest hits, ties the whole experience together: it’s loud, fun, and metal. Play’n GO has nailed the aesthetic here, blending rock energy with mystical visuals to create a slot that’s both immersive and electrifying.
Helloween RTP and volatility
Helloween comes with a 96.20% RTP, placing it comfortably around the industry average, while not on the same level as some slots with the highest return for UK players. The game features medium volatility, striking a nice balance between consistent payouts and those thrilling bigger wins during bonus rounds.
It’s built around the Seven Keys feature, which can trigger Wilds and multipliers at any moment, keeping every spin unpredictable and exciting. With a max win of up to 5,000x your stake, Helloween is packed with rewarding potential beneath its heavy-metal atmosphere.
Play Helloween on Mobile
We tested Helloween on our iPhone 15, and it’s safe to say that Play’n GO’s mobile optimisation shines once again. The game loads quickly, maintains sharp visuals, and runs smoothly without any lag, even during intense bonus rounds. The responsive HTML5 design ensures all interface elements, from spin buttons to volume controls, are perfectly sized for touch navigation.
Whether you’re playing in portrait or landscape mode, the dark, gothic aesthetic stays bold and vibrant, while the soundtrack keeps that concert vibe alive on the go. It’s clear Play’n GO built Helloween with mobile performance in mind, letting players rock out anywhere without missing a beat.
