Merlin's Grimoire Review

Just when you thought there wasn’t anything new that could be done in the ’Book slot’ genre, the creator of the iconic Book of Dead strikes again. Merlin's Grimoire is a visually pleasing forest adventure from Play’n Go, and you get plenty of voiceover commentary from the wizard himself.

What makes this game stick out however, is the symbol splitting mechanic you’ll benefit from in all stages of the game. It’s limited to only 3 reels in the base game, but symbols can split on all 5 reels at the same time in the bonus round. The special expanding symbol mechanic comes in addition, of course, and this can lead to 7,776 win ways and payouts up to 35,000x your stake.

Merlin's Grimoire Slot Features

The premium symbols pay between 2.5 and 4 x your stake for 5 of a kind, and the grimoire (book of spells) serve as both wild and scatter. As a wild, the grimoire steps in for all regular pay symbols to help complete wins, and as a scatter it triggers the bonus round. More about that below.

You can get Splitting Symbols in the base game, and this happens when reels 1, 2 and/or 3 are activated. All symbols on activated reels split in two, and this increases the number of win ways accordingly.

You need 3, 4 or 5 Grimoire scatters in view to trigger the Bonus Round, and this gives you an upfront payout of 0.8, 1.6 or 4 x your stake, respectively. You are then granted 10 free spins, and the book opens to reveal the special expanding symbol. You can retrigger the feature to win additional free spins during the bonus round.

The special expanding symbol covers the full reel if you land enough instances to create a win, and the special symbol doesn’t need to land adjacent to generate a win. All reels can become activated in the bonus round, which means all symbols can split, so the best case scenario is 5 expanding symbols on active reels. This gives you a 7,776 ways to win payout.

Review Summary

Play’n Go has taken the story-telling element to a new level with this release, as the voiceover commentary adds a layer of drama you don’t usually get in online slots. If you should find the commentary annoying however, you can always turn off the voice while keeping the other sounds. The visual presentation is highly enjoyable as well, and it’s nice to be outdoors in the forest instead of yet another claustrophobic tomb.

The splitting symbols keep the base game more interesting than the standard book slot, making larger payouts theoretically possible. They really shine in the bonus round however, not least since all 5 reels can become activated. This can lead to massive payouts up to 35,000x your stake, which is way above the regular 5K you get in this genre. The two simple elements combine really well, and it adds up to a very interesting ‘Book of’ mechanic release.
