Golden Grimoire Slot Review

Released February 2019

The Golden Grimoire slots game can be found at Net Entertainment casinos. Net Entertainment are one of the most established software providers on the market, being founded in 1996. Net Entertainment are a Swedish company but gained enough success to have offices all over the world. Net Entertainment do make the house edge information of their slots games available and this can be found in the help files of the game (usually accessed by pressing the ‘?’ button at the bottom left of the game window). As such, we can state that the House Edge for Golden Grimoire is 3.56%.

Golden Grimoire uses 5 reels that are 4 symbols high with 40 paylines, playing from left to right.

Special Symbols

Mystery Symbol – The “Spell Book” is the game’s Mystery symbol. Mystery symbols only appear on reels 3, 4 and 5 in the base game. When one or more Mystery symbols are added to the reels they will all transform into the same symbol. This can be anything from low paying, medium paying or Wild symbols. If the leftmost symbol in a row matches the Mystery symbol then all symbols between them will also transform into the same symbol. If the Mystery symbol turns into a Wild then it does not matter what the leftmost symbol is as all the symbols to the left of the Mystery symbol in that row will turn into Wilds.

Wild – The “Skull” is the game’s Wild symbol, substituting for all symbols except Scatter symbols and Mystery symbols. Wilds can only appear as the result of a Mystery symbol and when this happens all symbols to the left of the Mystery symbol will also turn into Wilds.

Scatter – The “Keyhole” is the game’s Scatter symbol, 3 of which in a single spin will trigger the game’s Free Spins feature. “Keyhole” symbols can only appear on reels 1, 3 and 5.

Bonus Features

Free Spins – Three Scatter symbols across reels 1, 3 and 5 will award you with 8 Free Spins. During the feature Sticky Mystery symbols will be available on reels 2, 3, 4 and 5. Sticky Mystery symbols act in the same way as a standard Mystery symbols except once they have been revealed they remain in place of the duration of the spins. With each spin the Sticky Mystery symbol will transform onto another random symbol. Free Spins cannot be re-triggered.


We have been waiting for a while to see what Golden Grimoire would be like, with Net Entertainment announcing its release around the beginning of the new year, and for the most part it has managed to live up to hype that the software giants have created. Net Entertainment are clearly hoping that this game will be a big hit and you can see the efforts that their designers have gone to in their attempts to bring us something special. For those who can pronounce the title of the game, a big well done to you, for those interested in what it means I can tell you that Grimoire is the name of a books of spells. That explains the importance of the game’s mystery symbols, which pretty much centres around everything good that this has to offer. The game looks great, it even sounds great and there are enough features to keep the gameplay interesting. I do think that we’re missing a bonus round and I’d like to have seen the Free Spins re-triggered and standard Wilds to go along with the Mystery symbol Wilds. The house edge is offering good value for money, meaning that this is a game we would thoroughly recommend you check out at some point soon.
