Merlins Grimoire Slot (Play n GO)

Merlins Grimoire Slot (Play n GO)Merlin’s Grimoire is a Book-style slot machine that was recently released by Play n GO. It relies on an Ancient Egypt-themed design, and so you will not be enjoying any new theme here.

The story is deeply inspired by Merlin, a famous character that was featured in all King Arthur stories. The Grimoire is a phrase used to mean a spell book, and therefore the Book connection is an obvious choice.

Game Set-Up

As with other Book-style slot games, Play n GO has used a 5x3 reels design, with a different system, and up to 243 ways to win. With other features coming in, the slot can get up to 7,776 ways.

For the features, we get to enjoy different original features that include Splitting Symbol mechanic, free spins with expanding symbols, and the usual mixed wild/scatters.

Betting and Prizes

Playing Merlin’s Grimoire for real money will only need $0.10 on each spin that you make. If your budget allows, then you can spend as much as $100 on each spin.

What I find very impressive about this slot is the high pay-out potential that the developer has offered. A majority of Book slots that I have come across pay a MAX of 5,000x, and the highest that you may get is 10,000xs.

However, this slot machine has the potential to pay up to 30,000xs the stake. It is clear that Play n GO did not waste the ways to a win-based engine that they included on the slot. It is also important to note that the slot has brutally high volatility, but the RTP of 96.2% serves it right.

Merlin’s Grimoire Slot Features

Initially, you get a 5x3 reels design, with just 243 ways to win. However, during random paid spins, you may see about 1 to 3 middle three columns that appear to have symbols split in two. In such a scenario, you will get additional symbols on the concerned reels, which then boosts the number of active ways to 1944 ways.

The Grimoire/spell book is the slot’s special symbol, and it will serve as the wild. In short, this is the feature that you will use as a substitute for other symbols, as you form winning combinations. At the same time, the feature serves as the scatter, which will help you to trigger up to 10 free spins (you will need 3 to 5 scatters in view to trigger it).

The Splitting Symbols may randomly show up on all the 5 available reels, and this is how you end up with 7,776 ways to win.

Merlins Grimoire has expanding symbols as well, and this is randomly picked at the beginning of the free spins feature. Symbols of that type will then expand on their reels (but only if they land on several reels in a left to right set-up).

Play n GO has included a sizeable prize in this slot game, and to trigger the top jackpot of 30,000x jackpot, all that you will be required to do is to land the top-paying symbol on the reels (these may then expand on the 5 reels throughout the free spins mode, whenever a round gets the symbols to split).

With 7,776 ways to win, you can get payments of up to 4x the stake each, which greatly boosts your chances of landing the top jackpot.

Theme & Design

The slot is set in a dark forest where a long-lost Celtic temple that is made out of stone is partially hidden. From the design and graphics that the developer has applied, it seems like the slot is inspired by Merlin, one of the most popular wizards.

In fact, he is clearly visible on one of the symbols that Play n Go has used. Others are scrolls, crystals, potions, plus six symbols that come in different signs.


Merlin’s Grimoire slot comes with a totally different concept, which breathes a new lease of life to the book genre. I especially love the expanding ways to win that form part of the special features.

If you enjoy slots in the book-genre, then you will have a chance to not only enjoy a great title, but to also trigger a massive jackpot.
