Golden Grimoire Slot


Sharing is caring!

Our rating:
  • A great looking slot, new from NetEnt
  • Mystery symbol feature works better than most we’ve seen
  • A fairly low variance slot with pretty small payouts

Golden Grimoire slot is a visually appealing, new slot from Netent that takes a common theme of magic and uses it to create some fun features with a nice design. The graphics are very good here, with a stunning backdrop set in some type of magical castle, and a set of reels with no border. There are 5 reels in total with just 3 rows, offering a total of 40 paylines. What you need to do is get a winning combination from left to right using the base symbols. These are as follows, ranked in ascending order as follows:

  • Diamond or Spades (lowest value)
  • Clubs or Hearts
  • Purple Jewel
  • Blue Jewel
  • Green Jewel
  • Red Jewel (highest value)

These symbols will pay you a cash reward when you get a win in the right combination. However, there are 4 additional symbols in Golden Grimoire slot that you’ll want to be aware of.


 Golden Grimoire Slot Bonuses and Features

Mystery Symbol Feature. The Mystery symbol is one you may have encountered in other slots and is usually pretty simple, but there are a few things you need to know here. Firstly, this one, shown as a mystery book, appears only on reels 3, 4 and 5 during the base game. When at least one of these symbols lands, a random symbol will be chosen which can include the Wild symbol and then every one of the Mystery symbols will turn into this symbol, hopefully given you some more wins. If the transformed Mystery symbol matches the leftmost symbol in the same row as the Mystery symbol, then every one of the symbols between them in that row will change into the same symbol which should give you even more wins. If you’re fortunate enough for the Mystery symbol to turn into a Wild symbol, all of the symbols between the Mystery symbol and the leftmost symbol in that row will change into Wild symbols.

Wild Symbol. The Wild symbol is pretty unique one because it only appears as a result of the Mystery symbol transformation. It’s shown as a golden skull and will substitute for all other symbols in a winning combination apart from the Scatter and Mystery symbol.

Free Spins Bonus. As you’d probably expect, this is triggered by 3 Scatter symbols which appear only on reels 1, 3 and 5. When this happens, you’ll be given 8 free spins. Note that they only appear during the base game. The special thing about this Bonus is that you have sticky mystery symbols in play. These are available only on reels 2, 3, 4 and 5. They work in exactly the same way as the non-sticky versions, turning into the same symbols and potentially transforming other symbols between them and the leftmost reel into that same symbol. However, once they land on a reels, they stay in place until the end of the Bonus. They transform into different symbols with every spin.



Golden Grimoire slot from Netent has a magical feel to it and this extends to the design. I really like the backdrop, but I do feel like the symbols could be improved. There are really only 2 features in this game. The first is the Mystery symbol which extends beyond what most other slots use it for, being able to transform additional symbols up to the left reel for extra wins, hopefully. The second is the Free Spins Bonus, which doesn’t offer much aside from the fact that the Mystery symbols become sticky. This is a nice idea, but I really would have liked to have seen potential for some bigger wins. I appreciate that this is a low variance slot, but a maximum potential of 200x your stake on a single spin is quite low. It’s not quite for me, although I understand that some people may enjoy this type of game. Be sure to let us know what you think down in the comments section below.
