Golden Grimoire online slot game

Golden Grimoire slot title is a unique slot game that will certainly attract those that love magic and a bit of mystery. As you play, you will come across a sticky mystery symbol feature, mystery symbol feature, free spins, and wilds but the catch is that these are all invisible!

Theme and Story Line

The Golden Grimoire slot title is themed on a book of spells which is called the ‘Grimoire’. Its spellbinding texts are held inside a magical room where symbols appear and magically disappear until the right formula triggers a spell resulting in combination wins.

Graphics, Sounds, and Animations

When you open the Golden Grimoire online slot, you are whisked to a spell room with a stargazing window. The stars rotate in the background while a cloud of mysterious magical dust blows calmly in the air, and the candles burn gently. On the reels, are all nicely designed and float or bobble in position. Basically, NetEnt wants you to know that you are about to embark on a fully animated 3D slot game which is exactly what you will get. 

The sound effects are quiet and eerie. You will hear is the sound of the reels spinning, then in the background creaking sounds, and plenty of other freakishly odd noises.

There are 5 reels and 20 pay lines to play across on the Golden Grimoire slot game. The slot divides its symbols into mystery, medium win, low win, and wild symbols. You can see these symbols by pressing on the ‘i’ button which reveals the slot’s paytable in a magical flash.

‘Medium Win’ symbols are made up of glistening gems with symbols and reptiles gripping onto each one. This set of symbols can pay anything between 100 coins and 5 coins multiplied the ‘Bet Level’. The ‘Low Win’ symbols are made up of playing card symbols which are spades, hearts, clubs, and diamonds. These pay from 20 coins down to 3 coins. All symbols form combinations of 3, 4, or 5 only. 

These payouts may seem a little low, but when they combine with the ‘Mystery Symbol’ these numbers make sense because the feature will activate multiple wins in a single spin. The mystery symbol will show up eventually and you will easily identify it as it is a thick book with a ‘?’ on it. You will also see a glowing gold symbol rolling on the reels which is the free spins scatter.

Bonuses and Free Spins

Mystery Symbol: This symbol only appears in free spins and is located on reels 2, 3, 4, and 5. When the mystery symbol is revealed, one of the medium win, low win and wild symbols will be selected. All mystery symbols on the reels will then turn into this symbol. If the selected symbol is the same as the symbol on reel 1 on the exact same row, then all symbols in-between will turn into that symbol. The same rules apply to the wild symbol, and so this pretty much guarantees you a big win!

Free Spins: Land 3 of the scatter symbols that are on reels 1, 3, and 5 in exchange for 8 free spins. 

Sticky Mystery Symbol: These symbols are only located on reels 3, 4, and 5. It will do exactly the same job as the mystery symbol, but instead of paying out and disappearing, it will stick in place throughout the entire free spins round. This means the magical effects of the mystery symbol will be applied after every free spin resulting in potentially huge wins every spin.

Bet sizes, RTP and Variance

Golden Grimoire comes with the usual NetEnt ‘Level Bets’ and ‘Coin Value’ with some high-stakes spin bets available. If you bet a ‘Level 10’ with a ‘Coin Value’ of 2.00, the total spin bet comes to 400.00 a spin. For the lowest bet, use ‘Level 1’ with a ‘Coin Value’ of 0.01 giving you 0.20 per spin. Every time you decrease or increase the ‘Level’ the ‘Bet’ value will adjust by -20 or 20 coins respectively. The RTP for your bets is 96.44% and the payout’s regularity means that this slot is set as a low to medium variance game.


The Golden Grimoire online slot uses the mystery symbol to good effect giving it two versions of its powers. The mystery symbol gives you the chance to notch up some big wins during the base game, but its true value comes to life in the free spins game when it sticks to the reels and continuously influences multiple symbol combinations which essentially means you should leave the free spins game with a tidy win!
