Golden Grimoire is an online slot developed by NetEnt. The game, which uses a 5×4 layout with 40 paylines, is set in a magical world and focuses on the Grimoire, a book of ancient sorcery. The reel is set in what looks like a wizard’s attack with candles, a spellbook, potion vials, a voodoo doll, a large window and glowing incantations on the wall.

Symbols in the game include bug and insect-covered gems in red, purple, blue and green colours as well as card suits in the same colours. The game, which has an RTP rate of 96.44%, is one of NetEnt’s most recent releases and it’s already earned praise from fans and critics alike. Let’s find out why.

How To Play

Before you can cast a spell, you’ll need to register and deposit at an online casino offering the game. Once you’ve done that, you can then click the purple spin button to get the game rolling. However, we do suggest you adjust your bets before doing so, this can be done by clicking the ‘+’ and ‘-‘ buttons beside ‘Level’ and ‘Coins Value’.

If you’re feeling lucky, you can hit the ‘Max Bet’ button to wager the maximum amount allowed in the game. You can also enable the game’s Autoplay feature, allowing you to sit back as the reels spin automatically for a set number of spins.

Special Features

Golden Grimoire

Like many modern-day slots, Golden Grimoire opens with a cutscene where glowing incantations and patterns flash across the screen until the slot appears. Once you’re on the slot, you’ll notice that the Wild symbol is represented by a skull. The Wild symbol can only appear as a result of a Mystery symbol transformation and when it’s on the reels it can substitute for all symbols except the Scatter and Mystery.

The Mystery Symbol

The Mystery symbol is represented by the Golden Grimoire with a question mark on its cover. The symbol appears on the third, fourth and fifth reels during the base game. Landing one or more Mystery symbols will cause a random Wild, low or high-paying symbol to be selected and the Mystery symbol will turn into that chosen symbol.

If the Mystery symbol matches the left-most symbol on the same row, all symbols between them transform into the same symbol, creating a large win. If the Mystery symbol transforms into a Wild, all the symbols between Mystery and the left-most symbol transform into Wilds.

Free Spins

Scatter symbols can only appear on the first, third and fifth reels. Landing three Scatters triggers the game’s Free Spins feature where you’re rewarded eight spins. The Free Spins bonus features Sticky Mystery Symbols which appear on the second, third, fourth and fifth reels.

These Sticky Mystery symbols act in the same way as the regular counterparts but these Sticky symbols remain on the reel even after they’ve been used. The Sticky Mystery symbols will remain on the reel until the feature ends and will transform into different symbols on each spin, helping you make winning combinations.


Golden Grimoire is a great online slot that benefits from high-quality visuals, a great soundtrack as well as some fun and exciting special features. The Free Spin and Mystery Symbol features will keep players interested for a long time, which is great. The slot itself is perfect for both first-timers and regular players as its easy to understand and play.
