Helloween Developer – Play’n Go

The story of Play’n Go is an enthralling one. Back in the mid 90s, a small group of tech savvy consultants realized that by pooling their talents together, they could build better software and systems then the corporations they were working for. So they did just that. And started Play’n Go.

They pride themselves on staying abreast of the latest technology. By utilizing their repertoire of technological knowledge, they are able to build iGaming solutions that are built for the future. Play’n Go was actually the first developer to utilise mobile-based online casino games, so they’re history in this space is star-studded. They’ll always be at the forefront of advancing the technological standard of the industry.

These are the developers behind Charlie Chance in Hell to Pay slotWild Candy slot, Rise of the Athena and Ice Joker. If you like Helloween, we’re sure you’ll find these just as interesting, or more!

Playing Helloween Slots Game

Helloween is a 5 reel slot, with 3 rows and 10 paylines. As usual, you need 3 matching symbols across any of the paylines, starting from left and moving towards the right, with the first symbol on reel 1.

The symbols you’ll be looking for are as follows: As, Ks, Qs, Js, 10s, and 9s; in addition to hands, ghouls, sorcerers, and gold rings. The most valuable symbol is the gold ring, with between 3-5 landing paying between 5-20x your total stake.

Interestingly, Helloween is a Halloween themed game, inspired by the German band of the same name. The online casino game is situated within a medieval tower, and the backing track is from the band’s albums. Cool!

Helloween’s betting range is from 10p to £10, so heavy rollers may feel excluded from this online slot. There is also an autoplay feature, where you can schedule 100 spins to run automatically, and if you feel it necessary, there are loss and balance limits to stop the spins in case they become too costly.

The RTP of Helloween is 96.2% which is perhaps slightly above average. The variance is in the medium range, and the maximum win is 5000x your total stake. As always, you can play the online slot on most internet-enabled devices.

Land 7 scatter symbols on reels 1, 3, and 5, and you’ll open this magical wheel. Oh, and in all features, scatters act as wilds.

Last Thoughts on Helloween Slot

Helloween is well designed and has more bonus spin features than almost all other slots we’ve ever reviewed. With so much variety, it’s an online casino game that you’d have to leave entertained. Play’n Go have done an excellent job here. But if you are looking for a more traditional casino game, may we recommend Glucks Joker?

Verdict: We give this a 7.5/10.
