Where to play?

Golden Grimoire slot is leading iGaming software developer Net Entertainment’s second video slot release for 2019. With 20 paylines (fixed), 5 reels, 4 rows this medium variance slot machine comes with a rather macabre theme that appeals mainly to fans of the genre.

The word ‘Grimoire’ is derived from Old French which has its origins in the occult, basically it gives the user a step-by-step guide on how to summon supernatural entities such as angels, spirits and demons. The jackpot up for grabs on a single spin is 8,000 coins.

When one or more mystery symbols land one or all mystery symbols are transformed into a random symbol for the BIG WINS! Playable on mobile devices (Androids, iOS, tablets) and PCs bets can be made from £0.20 to £100 per spin.

Aside from the game’s arresting visuals its mechanic centres around ‘Magical Transformations’, Wild substitutions and a Free Spins feature with Sticky Mystery symbols (awards up to 8 free spins). Symbols on the reels include a book of magic with all manner of spells, talismans, amulets, charms, skulls and the keyhole scatter. Against the backdrop of the reels you’ll see a portal to another dimension or so to speak. The RTP of Golden Grimoire is around the 96% mark.

Bonus Modes


The wild symbol (Skull) substitutes symbols adjacent to it (bar the scatter) when it completes winning combinations. It’s possible to get a full screen of wilds, if you can accomplish this feat wins can be spectacular! (Super Mega Win). However, the wild only appears after a mystery symbol transformation for even greater rewards.

Mystical Free Spins

”With a bit of luck you might stumble upon a pattern of three scatters…”

It took us around 50 spins to trigger the free spins feature which awarded us 8 free falls. The bonus round is triggered when 3 keyhole scatters appear any position on the reels during the base game. We played Golden Grimoire with a bankroll of £50 at an average bet of £0.50 per spin, the impression we get is that payouts at this bet level leaves a lot to be desired. To improve your chances of getting decent wins play it a minimum bet of £2 per spin.

To get into the good stuff, i.e the BIG WINS your average bet must be at least £10 per spin, obviously this also depends on the size of your bankroll. The biggest win we had during the free spins was 40x our stake which we guess is okay taking our average bet size into account. However, it’s possible to hit the ”Super Mega Wins” in the free spins where you can pocket as much as 1,000x your stake on each free spin in conjunction with those symbol transformations.

Looking back Golden Grimoire is one of those games that grabs you from the very first spin or it doesn’t. Sadly it’s not for us, playing the game it’s like watching the plot of a horror movie unfold with a lackluster twist. The free spins feature for the lack of a better word is ”mediocre” yes we get it it’s a Net Entertainment slots so it’s supposed to be good, not! Consider yourself lucky if you get a Big Win of 150x your stake during the free spins.


Golden Grimoire Slot frequently asked questions

How many in-play bonus rounds does the 3D slots have?

As far as we understand it has one bonus round namely a ‘Mystical Free Spins’ feature that’s initiated when 3 scatters appear – 8 free spins are awarded in conjunction with symbol transformations.

Payouts during the free spins can be anything from 50x to 200x your stake, don’t bank on it though. The skull which is the wild symbol pitches during the free spins too.
