Golden Grimoire is a five-reel, 40-payline game created by NetEnt centered on magic, mystery and an ancient book called the Golden Grimoire.

First things first: a lot of you will be asking what exactly is a grimoire. Well, a grimoire is a magic book or maybe better called a sorcerer's diary with instructions on how to formulate amulets, cast spells, or summon spirits, originating from Old French. Not long after loading the Golden Grimoire slot, you will find yourself inside a dim sorcerer’s chamber at night, faintly lit by candles and the moonlight peering through a giant round window in the background of the translucent game window.

Try as you might, you will find that cannot fight off an eerie feeling, which will be further heightened by intermittent hieroglyphs emerging on the walls, objects levitating on teaser spins, and an ominous soundtrack that is blended with classical elements. Now let’s talk graphics as they will no doubt grab your attention from the get-go. Alchemy and magical books surround you as you spin reels to unlock the mysteries that lie beneath the surface of your world. Maths and Graphics work together on this one to give the Mystery Symbol special importance.

Golden Grimoire also comes with several hidden secrets. The names of the artists appear in different pentagrams and glowing symbols on the walls. Also, the team’s logo can be seen on the book on the left in the main game. The names of the members of the team that made the game, appear in the magical sigil.

In all, Golden Grimoire is a well-designed game that features superbly-rendered graphics as well as an authentic theme, which essentially lives up to the high bar that is often set by the creative team over at NetEnt. Unfortunately, that level of creativity apparently did not carry over to the math people who produced yet another low-variance game that will hardly lift an eyebrow among avid gamers. But it is totally understandable as NetEnt is trying to cover all types of players, developing a mixture of low, medium, and high variance games.


The four higher value symbols are gems inlaid with golden creatures, which are a spider, a snake, a moth and what appears to be some tentacles. Glowing playing card symbols in orange, green, blue and purple signify the lower values. The wild that only appears as part of the features, is a golden skull which will take the place of all others to help land winning combos except for the Mystery and scatter symbols.


Mystery Symbol

The Mystery symbol appears on the reels as the Golden Grimoire and when it lands, it will transform into one of the standard symbols or the wild. If it matches the symbol on the same row on reel one, all positions in-between will become that symbol as well and the payout will be made. If it’s wild then it will definitely match.

Free Spins

The Free Spins is initiated by landing three of the keyhole scatter symbols anywhere on reels one, three and five. Do this and you’ll get eight free spins. During this round, any Mystery symbols which land will stay in place for the whole feature, turning into a different symbol with each spin. It’s not possible to earn any more spins from within this round.
