Complete with its own immersive intro, Merlin's Grimoire is a slot that many would agree is a true visual masterpiece. The game follows a wizard on a journey that leads him into the forest, only to be confronted with an ancient temple that is covered in overgrowth. It’s this exact temple that doubles as the board within Merlin's Grimoire, which contains a popular bonus mode alongside an interesting mechanic.
Merlin's Grimoire is a slot created by Play'n GO, with this game following in the footsteps of previous titles that have all been easy on the eye. These releases include top slot machines such as Rise of Athena, Eye of Atum, and The Green Knight. The minimum bet size for Merlin's Grimoire is 0.10 per spin, with the maximum potential win being 30,000x. Finally, this slot is optimised for both desktop and mobile play, which is the case with most releases from Play'n GO.
The symbols in Merlin's Grimoire are relatively unique, with the common 10, J, Q, K, and A symbols being replaced by ancient coins with different icons on them. These appear in the colours green, blue, purple, orange, red, and yellow. The first three symbols will award 0.8x if 5 match along a payline, with the orange, red, and yellow icons awarding 1x the total stake size.
Next up are the premium symbols, which consist of a scroll, a potion, a wizard's staff, and finally, Merlin himself. Matching 5 of these symbols can award players with 2.5x, 2.5x, 3x, and 4x, respectively. Finally, there is a book symbol that acts as the wild and scatter icon within Merlin's Grimoire.
An interesting mechanic that appears within Merlin's Grimoire is known as ‘Split Symbols’. Randomly, reels 2, 3, or 4 can activate, which will split symbols into two. This can happen to a single reel, or all 3 reels simultaneously, with this mechanic having the potential to increase the number of active paylines.
Now it's time to take a look at the main bonus, which can be activated if 3, 4, or 5 book symbols appear across any of the reels. Regardless of the number of scatter icons, players will be awarded with ten spins. However, the potential winnings for the triggering spin can either be 0.8x, 1.6x, or 4x the stake size, respectively.
At the start of the bonus mode, the pages of a book will turn to reveal a random icon. This will act as the expanding symbol for the duration of free spins, meaning that it will fill the entire reel if it’s part of a matching combination. This can mean that players are awarded across a variety of paylines.
During this mode, the ‘Split Symbols’ mechanic will also be active across all reels, not just the middle three. The maximum number of paylines, which sits at 7,776, can be activated if all reels activate the split mechanic during the same spin.
This release by Play'n GO is packed with visually appealing aspects, from the user interface to the range of unique symbols. Merlin's Grimoire also contains some exciting mechanics, one of which can potentially increase the number of active paylines.
