Quick verdict: Helloween is a Play’n GO slot from October 2020 built around the German power metal band Helloween, with a 96.2% RTP and medium volatility. It plays on 5 reels and 3 rows with 10 paylines, and its soundtrack uses songs from the band’s Keeper of the Seven Keys albums. Three scatters spin a wheel that picks one of seven free spins features, six of them named after songs and each with its own pumpkin wild. Review sites disagree on the max win (2,000x or 5,000x), and Play’n GO’s own page does not give one.

Pumpkin wilds and the seven song features

  • Base game: wins pay on 10 fixed paylines across a 5×3 grid. The best line pays 20x your stake, for five gold rings or five wild pumpkins.
  • Wild pumpkin: stands in for the regular symbols. In each free spins feature the pumpkin gets a different behaviour, which is where most of the game’s winning potential sits.
  • Scatters: land only on reels 1, 3 and 5. Three of them start the Keeper of the Seven Keys wheel.
  • I’m Alive: wilds stick and grow one position up or down on every spin. Once a wild fills its whole reel, it clears on the following spin.
  • Future World: every wild that lands expands to cover its full reel.
  • Eagle Fly Free: a wild flies onto the reels on each free spin and changes position on later spins, so the wild count can build up as the feature goes on.
  • Dr Stein: on each spin one royal (A to 9) is picked at random, and every copy of it on screen turns wild.
  • March of Time: wilds stay on the reels and walk one reel to the left after each spin until they leave the grid at reel 1.
  • I Want Out: any wild that lands grows into a 2×2 block.
  • Helloween Free Spins: the seventh wheel prize and the only one that starts with 7 spins instead of 5. It is also the only mode that can send you back to the wheel.

How the Keeper of the Seven Keys wheel works

The bonus starts when three scatters land on reels 1, 3 and 5 in the same spin. None of the sources we checked publishes how often that happens, or the odds of each wheel segment.

  1. Land three scatters on reels 1, 3 and 5 to spin the Keeper of the Seven Keys wheel.
  2. The wheel stops on one of seven features: I’m Alive, Future World, Eagle Fly Free, Dr Stein, March of Time, I Want Out or Helloween Free Spins.
  3. The six wild features each give 5 free spins and cannot be retriggered. Helloween Free Spins gives 7.
  4. In Helloween Free Spins, collect 3 scatters to spin the wheel again. Each retrigger adds another 7 free spins.
  5. When any feature ends, the Helloween Multiplier may trigger at random and multiply that feature’s total win by up to 10x. SlotCatalog, LCB and SlotsTemple list the values as 2x, 3x, 5x or 10x.

Bonus buy: no. Play’n GO’s page describes no feature buy, and Casinos.com and LCB mark it as not available. The only way into the wheel is three scatters.

2,000x or 5,000x: what is the real max win?

We can’t confirm either figure, because Play’n GO’s game page gives no max win and the review sites split. Gambling.com and Casinos.com say 2,000x your stake, which is 200,000 at the 100 top bet. SlotCatalog and SlotsTemple say 5,000x, and LCB’s review text also says 5,000x while its own data table shows a 2,000 top prize. SlotsTemple’s data table even lists 20,000x. What is solid is the paytable: the best line pays 20x, and the bigger wins come from wild-heavy features topped up by the Helloween Multiplier of up to 10x. Open the paytable in the game before you rely on any max-win number.
