Originally Grimoire is the European ceremonial magician’s book of spells but the historian Owen Davies noted that similar books can be found all across the world, ranging from Jamaica to Online Casinos. One of such Grimoires provided by the NetEnt Company, which called “Golden Grimoire” Slot and contains spells that bring                                                                       golden equivalent in EUR/USD/GBP/NOK/SEK.

The original medieval symbols and stunning themes, combined in this slot are really impressive. Online slot looks very magician. And other witchcraft characteristics are pleasantly surprised too. The developers have done this slot with an old chappels theme, and it reminded me Sainte Chapelle in Paris.

Game’s playing field is full of hearts, spades, clubs, and diamonds as well as beetles, snakes, cephalopod mollusks and spiders holding on to gemstones. The online slot uses the usual scheme of the organization of the playing field – 5×4 and has 40 fixed pay lines of low to medium volatility. Default RTP setting of 96.44% which is high enough to play this game.

Central to the game is the Mystery symbol that comes in the form of a spellbook with a question mark. Just like all other symbols, it appears fully stacked on the reels but may only appear on reels 3, 4 and 5 in the base game. When it lands, a random symbol is selected, transforming all instances of the Mystery symbols into that symbol. Now, if the Mystery symbol matches the leftmost symbol in the same row, all symbols in that row will transform to the same symbol. If the Mystery symbol turns into a wild, however, the same things happens only this time all symbols in that row turn into wild symbols regardless of the symbol on the first reel.

After symbol transformation golden skull can appear which represents Wild.

If you land 3 scatter symbols on reels 1, 3 and 5 respectively you will get 8 Free Spins. It’s all about the Mystery symbol here, but while the basic functionality is the same, Mystery books are now extended to appear on reel 2 as well. More importantly, any Mystery symbol landing on the reels will stay in place throughout the bonus session. The bonus cannot be retriggered.

This slot will find its fans when playing for bonus funds, since, considering its functionality, it should be quite good to keep balance.
