NetEnt invites you to enter the Sorcerer’s chamber in the Golden Grimoire online slot, a 5-reel, 4-row slot game with 40 fixed paylines. The word “Grimoire” allegedly originates from Old French times and basically translates into a book of magic spells. And bewitching it is, with stunning visuals and animations. It also has great features like the transforming Mystery symbol, which can become all other symbols including wilds. that become sticky in the free spins round.

Game Symbols

  • There are 8 standard symbols that appear fully stacked on the reels, both in the base game and bonus rounds. These include hearts, spades, clubs and diamonds as well as a higher-value beetles, snakes, molluscs and spiders with gemstones. The latter are most rewarding, giving you 5x your stake for 5 across an active payline.
  • The Mystery symbol is central to the game and appears as a spell book with a question mark. We will explain how it works further down.
  • The golden skull is wild and can only appear as a result of symbol transformation. It replaces all other icons to help form wins, except for the scatter symbol.

Bonus Features

Mystery Symbol

During the base game, the Mystery symbol appears fully stacked and may only appear on reels 3, 4, and 5. When it lands it will transform into a randomly selected symbol. If it matches the leftmost symbol in the same row, all the symbols in that row will change to match. Should the Mystery symbol turn wild however, all other symbols in that row will become wild too. 

To get a complete screen of the same pay symbol plus a decent win, you’ll need to hit a full stack of one symbol on reel one and a full stack of the magic books on reel five. Pays for full screens range 30x for the lowest pay symbol to 200x your stake for the top symbol.

Free Spins

The action goes up in this feature, which kicks in by landing 3 keyhole scatter symbols anywhere on the 1st, 3rd and 5th reel. You will be awarded with 8 free spins, and during this round any Mystery symbols that land will remain in place for the entire feature, transforming into a different symbol with every spin of the reels. Note that the free spins cannot be re-triggered.

Our Verdict

Golden Grimoire is a fun and well-crafted slot. The highlights are definitely the Mystery symbols that can transform into wilds and the Free Spins with sticky mystery symbols. We are a little disappointed that the max win is only 200x your stake, and we’re guessing that this is NetEnt’s attempt to cater to all types of players, in which case, this game is perfect for the casual fan.
