Rolled out by NetEnt, Golden Grimoire is a video slot that will lure you into the realms of mystery and the occult. A candle-lit chamber filled with magical artefacts is there to help you unravel ancient secrets and unearth well-kept treasures. Be on the lookout for Mystery Symbols, Wilds and Scatters since they could help you trigger various features and obtain hefty prizes going as high as 80,000 coins.

Golden Grimoire is a 5-reel, 4-row slot with 40 fixed paylines to wager from as low as $0.20 and as high as $400 per spin. Once the game loads enter bet settings to adjust the bet level on a scale from 1 to 10 and choose the coin denomination that goes from $0.01 to $2.00. Get the reels going by tapping Spin or activate up to 1,000 automatic rounds. In order to receive payouts, symbols should appear on consecutive positions beginning with the leftmost reel.

The reels are home to 8 symbols, 4 medium,and 4 low-paying ones. Precious stones, Amethyst, Turquoise, Emerald and Ruby award from 5 to 10 coins for 3 of a kind, while combinations of 5 bring more significant payouts of 30, 40, 75 and 100 coins respectively. Playing card suits represent low-value icons delivering merely 3 and 4 coins when 3 are on a winline and awarding players with 15 and 20 coins for 5 of a kind. The Mystery symbol, depicted as a Spellbook, can land on the 3rd, 4thand 5th reel, changing into a randomly chosen symbol. If it matches the icon on the leftmost reel, all symbols in between transform to match the Mystery symbol. The same thing happens if the Mystery symbol changes into Wild which appears only as the result of this transformation. Wild is represented as a Skull and can substitute for all symbols except for Scatter and Mystery.

Scatter, represented as a Keyhole, lands on reels 1, 3 and 5 only and when 3 appear they trigger the free spins round awarding 8 free spins. During this feature, the Sticky Mystery symbol is active on all reels except the reel 1. It works the same way as the base game Mystery Symbol, but once it lands, it remains on its reel until the feature finishes thus increasing your winning chances.

A sinister musical score, superb graphics and neat animations, along with a slightly above the average RTP of 96.44%, will boost your excitement and contribute to delivering a gripping gaming experience. However, keep an eye on your bankroll as this high-volatility slot could leave you empty-handed.
