Our Verdict: As big advocates of NetEnt mobile slots, we have to confess that Golden Grimoire blows us away. The supernatural theme is complemented by the excellent graphics and sound effects while the gameplay is ramped up through the Free Spins Bonus and Mystery Symbols Feature.
You can enjoy the Golden Grimoire slot game on a variety of mobile devices with stakes of 20p up to £400.
Land three Spell Books anywhere in view, and you benefit from sticky mystery symbols throughout the free spins round where the wild symbol comes into play.
Design: Golden Grimoire delivers a spine-tingling experience with its suspenseful musical soundtrack and eerie sound effects.
When the game start to play on your mobile device, you find yourself within a tower high up in an ancient castle which, by the looks of the surrounding objects, belongs to a powerful sorcerer.
According to legends, a grimoire is a book of spells, and there are many such books lying on the tables within the tower next to flickering candles. There are also potion bottles, and incantations scrawled on the walls, and a large window which looks up at the planets and stars.
The Golden Grimoire slot uses five reels, four rows of symbols, and forty fixed paylines, and winning combinations can be created from left-to-right, beginning with the leftmost reel.
Each paytable symbol in Golden Grimoire is associated with a different cash value such as the skull, the amethyst, the sapphire, the club, the diamond, the heart, and the spade.
The NetEnt Touch software makes it easy to change your bet size, consult the paytable and rules, and use Auto-Play on your mobile phone or tablet. And, there's also option to locate the Spin button, and other game controls to the left or right of the screen.
Wild Symbol: The Golden Grimoire slot game uses a wild symbol to make it easier to create winning combos, but it only features in the Free Spins Bonus where it becomes sticky. The wild can replace all symbols except scatters.
Bonus Features: The Mystery Symbols Feature plays a big part in both the base game and the Free Spins Bonus of the Golden Grimoire slot, and it's activated by the special Golden Grimoire (i.e., Spell Book) symbol.
In the base game, Mystery Symbols become one random symbol at the end of the spin, and if the random symbol matches the symbol on the same row of the first reel, all other symbols in between also turn into the random symbol.
In the Free Spins Bonus (which is triggered with three Skull scatters), you receive eight free spins, and the Mystery Symbols become sticky throughout the feature.
