Enter a mystical room at night where the moonshine on a cloudless night shining through the round window to sparsely illuminate rustic armoires and flower pots. Together with the dim candle lights in the front of the frameless game window and the intermittent appearance of ancient hieroglyphs on the walls, it creates a eerie feeling of suspense and mystery, which is only heightened by a rumbling soundtrack mixed with classical tones that changes to dramatic crescendos on teaser spins, big wins and when the golden grimoire lands on the reels.

Golden Grimoire is a video slot with five reels, four rows and 20 fixed pay lines, featuring wild substitutions, mystery symbol transformation and a free spins round with sticky mystery symbols.

The RTP of this low variance game is set at 96.44%. You can spin the reels of this slot on any mobile, tablet or desktop from 0.20 to 400 coins. Hit five on a pay lines to win 0.75x to 5x your bet.The maximum win potential is an unusually 200x bet for a full screen of the top symbol or in combination with wild symbols. This puts Golden Grimoire into the same class with Universal Monsters: The Phantom’s Curse™ and Witchcraft Academy. Not the best association in our view as we call this slot category egg-timers where a balance slowly but steadily decreases with little potential to score substantial wins.

The low-value symbols glow with a coloured hue that match the colours of the high value symbols. They are in ascending order – diamonds with a purple hue, spades with a blue hue, clubs with a green hue and hearts with a red hue. At the high end are then four coloured gems, each held by a mystical critter – a purple gem held by scarab, a blue gem held by a snake, a green gem held by a kraken-like creature and a red gem held by a spider.

The wild symbol is a golden skull, appearing only when revealed from the mystery symbol transformation and will substitute for all symbols except scatters. Those are an artistically designed tile with a keyhole and the word itself across it.
