Betting Options and Bonus Features
Merlin’s Grimoire is the newest twist on the “Book Of” slot genre invented by Play’n GO. It features the iconic expanding symbol bonus game as well as the splitting mechanic that is also unique to this slot provider.
The game’s main symbols are the five wizard-themed premium symbols that pay between 2.5x and 4x your stake on five-of-a-kind win combinations, as well as the grimoire symbol. Besides serving as a Wild symbol that substitutes for regular pay symbols, the grimoire also acts as a Scatter that is responsible for triggering the bonus round.
During the base game, reels 2, 3, and 4 feature a thunderbolt icon on top that is randomly activated. This will split all symbols on the reel in two, drastically increasing the number of win ways. The game starts with 243 win-ways but you can potentially unlock up to 7,776 paylines at once!
Activating the Bonus Round requires 3, 4, or 5 Grimoire scatter symbols, and this gives you an upfront payout of 0.8, 1.6, or 4x your stake, respectively. You start with 10 free spins and the magic grimoire will open and select your expanding symbol. This symbol, whenever landed, will expand and cover the entire reel!
In addition, every reel now possesses the thunderbolt icon which can be activated to split your symbols in two. In combination with the expanding symbol, this can lead to extremely volatile wins and you can get up to 35,000x your stake! Landing additional grimoires will retrigger free spins which can be done up to 5 times.
Quite a refreshing take on a “Book Of” slot gameplay with a fat payout potential. It’s hard to say how realistic it is to reach max win since it's a Play’n GO slot and they love to throw big numbers around, but this type of potential is definitely nice to have.
The bonus game is extremely straightforward which is a delight to see. You get your books, unlock the bonus game, select the expanding symbol and unlock the splitting feature on all reels. No silly conditions or progress bars. All gas, no brakes, from the start. That’s what bonus games should be.
