NetEnt has faced some criticism from players regarding the consistent release of one low- or medium-variance casino game after the other. Golden Grimoire also falls within that category, though a break from the usual 5×3 reel layout goes some way to improve things.

Overall, we think this online slot does have redeeming features, not least its display of NetEnt’s standard-setting animation and overall visual design. But players looking for something out of the ordinary would be better served with a different game.

Let’s take a look at how Golden Grimoire stacks up and the kinds of features built into this game. Abra cadabra!

Golden Grimoire bonus features

This slot is simply dripping with atmosphere! NetEnt’s superb visual design transports us into a realm of ancient magic, where anything is possible if you know the magic words. The action could easily be taking place in a wizard’s secret hideaway or perhaps an apothecary.

By way of symbols, we can see diamonds, spades, clubs and hearts. Different insects cling on to brightly coloured gemstones, making up the rest of the symbol repertoire. The symbol with the spider is the most rewarding of these, offering 5 times the stake when five land on a payline.


The skull symbol is the Wild in Golden Grimoire. It can substitute for any other symbol except for two – the Scatter and the Mystery Symbol, which we will talk more about in a minute. With a little magic from the Mystery Symbol, the Wild symbol can be also be sticky.

Golden Grimoire Free Spins

Free spins on Golden Grimoire are triggered when the Scatter symbol appears on reels 1, 3 and 5 simultaneously. When that happens, the player is awarded 8 free spins.

During the free spins rounds, Mystery symbols become Sticky and can appear on reels 2 to 5. Sticky Mystery symbols will remain in position throughout the free spins rounds. If the symbol is transformed into a Wild, the player will enjoy sticky Wilds for th duration of the free spins.

Mystery Symbols

The spellbook is the Mystery Symbol and it triggers all manner of magical moves! Mystery Symbols can appear on reels 3 to 5. When one or more spellbook symbols appear, a random symbol is selected. Any and all mystery symbols on the reels will be converted into the selected symbol, which can be a Wild symbol too.

That’s not all though. If the transformed Mystery symbol is the same as the symbol on the far left of the same row, all the other symbols in between the two will become Mystery Symbols, and thus the selected symbol for that spin.

If the selected symbol is a Wild, all symbols between the Mystery Symbol and the leftmost symbol in the row will convert into Wilds, no matter which symbol is on the first reel. The Wild can replace every symbol except the Mystery and Scatters.
