The dazzling Golden Grimoire slot on our mobile phone casino is set to become just as much a legend as the magical book that it takes its name from. The game is a fantasy-themed title from NetEnt whose focus is an ancient book of the occult. Entirely what’s written on its pages, nobody knows, but as the French word “grimoire” means a book of magic spells and invocations, we can only assume that it must be extremely powerful.
The Golden Grimoire slot game offers you twenty fixed paylines, five reels, and four rows of symbols, and you can play it on all devices with bets of 20p to £400.
The mysterious Golden Grimoire appears on the paytable as the Mystery Symbol, and it can perform symbol transformations to conjure up potential big wins. There are also low-value playing card symbols, skulls, and a variety of talismans and amulets.
The playing experience takes you to a chamber high up in a tower of an old castle which, judging from the paraphernalia strewn around the room, belongs to a powerful wizard. Burning candles cast shadows on the spell books and vials that lie on the wooden tables, and a round portal at the back of the study looks up into the night sky. When the Mystery Symbol Feature is triggered, the music gets louder and the objects on the tables start to float around the room, sending chills down your spine.
Running underneath the reels of the slot, you have a variety of buttons and icons that let you mute the music, change the coin value and bet level, look at the paytable, turn on Auto-Play or place the maximum bet.
NetEnt has used the Skull to represent the wild symbol within the Golden Grimoire slot. Like most wilds, it can help you win more frequently by substituting for other symbols apart from the scatter. But, in the case of this slot game, the wild can only appear on the reels through the Mystery Symbol Feature.
The scatter symbol in the Golden Grimoire slot is the Keyhole, collect 3 or more to be awarded the free spins feature.
The Spell Book is called the Mystery Symbol in the Golden Grimoire slot, and if it lands on the third, fourth or fifth reel of any spin, it turns itself and all other spell books into one of the other paytable symbols. If the symbol that lies adjacent to it on the first reel happens to match the chosen paytable symbol, all symbols between them are also transformed.
The Free Spins Feature is unlocked when the Keyhole scatter appears on the first, third, and fifth reel simultaneously. You receive eight free spins, and during the feature, the Mystery Symbol can land on Reels 2, 3, 4, and 5.
Any Mystery Symbols that come into view are held in place until you’ve taken your last free spin, upon which, all of them are transformed into a randomly chosen symbol. If you’d like to try another exciting fantasy-themed game, make sure you play the Forbidden Throne slot.
