“What is a grimoire?” This is often the first question we get asked about this game. It’s a book of spells. A textbook of mystery. A set of instructions for how to create metaphysical objects. In other words, magic – this slot is full of it.

The game is a 5-reel, 4-row, 20-fixed line video slot featuring Mystery symbol transformation, Wild Substitution and Free Spins with Sticky Mystery Symbol transformation. There’s other magical slots to discover in our collection of online slots. But no magical slot is complete without a magical casino bonus to go with it. Browse our collection and see what wonders you discover!

The mystery symbol appears on reels 3, 4 and 5 in the main game. When one or more Mystery Symbols land, a random symbol is selected from the Wild, medium or low win symbols, and all Mystery symbols transform into this symbol. The mystery symbol is the Golden Grimoire™, which is shaped like the infamous mysterious book that inspired the game.

Wild symbols can appear only as a result of Mystery symbol transformation. The symbol substitutes for all except the Scatter and Mystery symbol. Collecting 3 Scatter symbols (on reels 1, 3, 5) triggers 8 Free Spins. During Free Spins, the Sticky Mystery Symbol replaces the mystery symbol that appears on reels 2, 3, 4 and 5.

Now let’s talk graphics – they will grab your attention from the get-go. Alchemy and magical books surround you as you spin reels to unlock the mysteries that lie beneath the surface of your world. Maths and Graphics work together on this one to give the Mystery Symbol key importance. Anticipation is built through cycles of symbols (such as the near win). Coinciding Win is 200x bet per full screen of max symbols, and could happen during multiple free spins, so the max win could theoretically hit heights as high as 800x bet.

This delightful gem of a slot also comes with a number of hidden secrets. The names of the artists appear in various pentagrams and glowing symbols on the walls. Also, the team’s logo is visible on the book on the left in the main game. The names of the members of the team which made the game appear in the magical sigil.

Golden Grimoire™ is a magical sort of slot game, and the magic words are Free Spins and Wilds! Experience excitement during Mystery Symbol transformations and cast spells to open the portal to another world. Hit spin and find out what secrets Golden Grimoire™ has in store for you.
