Golden Grimoire Slot Review

Golden Grimoire is a low variance slot from NetEnt with 5 reels and 40 paylines. Set in an ancient magical world, there are Mystery symbols which transform into another symbol including the wild – if the transformed Mystery symbol is the same as the symbol on reel 1 and on the same row, all those symbols transform too. If you get a wild for the Mystery symbol, all symbols on the row become wild too. This applies in the Free Spins feature but the Mystery symbol is sticky which means you could end up with lots of sticky wilds.

Golden Grimoire is powered by Net Entertainment and has 5 reels, 4 rows and 40 paylines. You are transported to another world full of riches from just 20p to £400 a spin across all devices. The slot offers you mystery transforming symbols and a free spins feature with sticky mystery symbols.

Visually, Golden Grimoire has an ancient magic theme and its based on a spellbook – with a magical and mystical feel, symbols on the reels include hearts, clubs, spades and diamonds as well as various insects embracing coloured gemstones. The one with the spider is the most rewarding giving you 5 times your stake for 5 on a payline. There’s also a wild (skull) which is discussed more below.

Golden Grimoire comes with a Mystery Symbol feature – when 1 or more Mystery symbols (the spellbook) lands, a random symbol is selected. This can any symbol including the wild. The Mystery symbol appears on reels 3, 4 and 5 in the base game. All mystery symbols then transform into the chosen symbol.

If the transformed Mystery symbol matches the leftmost symbol in the same row, all symbols in between them will also be changed into the transformed Mystery symbol. If the Mystery symbol transforms into a wild, all symbols between the Mystery symbol and the leftmost symbol in that row will become wild, regardless what’s on the first reel. The wild replaces all symbols bar the scatter (and mystery symbol).

There’s also a Free Spins feature which is played when you get 3 scatter symbols on reels 1, 3 and 5 simultaneously – your reward will be 8 free spins. Instead of the Mystery symbol there’s a Sticky Mystery symbol which can appear on reels 2, 3, 4 and 5.

Sticky Mystery symbols act in the same manner as Mystery symbols but will trigger the Sticky Mystery Symbol feature – once a Sticky Mystery symbol lands, it remains in position for the duration of the free spins. If the Sticky Mystery symbol transforms into a wild, you’ll benefit from sticky wilds throughout the free spins.

Despite the great visuals and potential sticky wilds in the Free Spins feature, Golden Grimoire is a low variance slot – this is because you can only win a maximum of 200 times your stake on every spin/free spin (if you manage to fill the reels with the highest value red gem/spider symbol and/or wilds.

Personally, that doesn’t make Golden Grimoire attractive to me – if you want slots based on books that can reward you with bigger payouts, you cannot go wrong with Play ‘N Go’s Book of Dead as each spin/free spin can pay out to the tune of 5,000 times your stake.
