Play’n GO is undeniably one of the best studios in the business. Over the years, it has released endless hits, including the likes of the Book of Dead slot. The studio often dabbles in English folk stories, having released a set of Arthurian slots. The legend continues with a bit of a grim tale titled Merlin's Grimoire.

This one pairs the best of Play’n GO’s favorite slot types – Arthurian legends with the ‘Book of…’ mechanic. It comes with a pretty unique tale and gameplay mechanics that will surprise all types of players. In short, you start with 243 ways to win, but those can be upgraded to 7,776. Splitting symbols and the obligatory ‘Book of…’ Expanding Wilds are also in the mix, creating quite a unique ride.

The slot is available for free and real money in any top online casino. If you like the Book of Mysteries, this one hits the mark.

Merlin’s Grimoire doesn’t differ from the majority of Play’n GO slots. It’s a highly volatile title with an RTP of 96.2% and a 5x3 layout. Of course, the graphics and animations are top-notch, so you can see the wizard in pitch-perfect detail.

Click on any of the symbols to check their payout. The Book Wild/Scatter and Merlin pay the most, delivering wins of 4x for five on a line. When part of a winning combination, the slot animates the characters, which is a nice touch.

On top of it all, an epic soundtrack can be heard in the background. It goes perfectly in hand with the visuals and theme, making it a gorgeous game to play from all aspects. From time to time, Merlin will tell bits and pieces of the story in a rough voice, adding to the mystery of the game. Play’n GO is a master of storytelling and that’s evident in this game.

You can play the Merlin’s Grimoire slot on any mobile device with ease. No need to download any casino app. Open up your favorite Android or iOS browser and play it on the spot.

By default, the bet in Merlin’s Grimoire is set to $1.50 per spin. You can choose between $0.10 and $100 and hit the Spin button to start. While the base game might seem uninspiring, remember that the slot’s split reels system can double your wins and the ways to win.

The Symbol Splitting mechanic is active in all stages of the game. It occurs randomly and is limited to three reels in the base game. Symbols can split on all reels, greatly increasing the winning ways and payouts too. It’s an excellent feature that can light up your wins in the base game.

Of course, the top action follows in the Bonus Round, where the grimoire (book) takes center stage.

As mentioned, three or more grimoires grant you entry into the Bonus Round. They also pay a small prize of up to 4x the bet for five. The bonus starts with 10 free spins, with the book revealing the Expanding Symbol before it begins.

It’s a straightforward Free Spins Round with a few surprises. More grimoires will add extra spins to your tally. The Expanding Symbol can help you win big, and all reels can be split in the bonus. The Splitting mechanic can even split the Expanding Symbol, which can end up on all 5 reels for the biggest wins.

The Merlin’s Grimoire slot has an RTP of 96.20% which is common for highly volatile Play'n GO slots. It has a massive winning potential – with a bit of luck, the top reward you can win is 30,000x the bet.

We’ve grown to like Play'n GO’s Arthurian slots, but this one’s different. It’s much darker and more rewarding, and we love it for that. It pairs the ‘Book of…’ mechanic with a Splitting Feature that can lead to pretty nice wins.

The Bonus Round is where you can hit the biggest wins thanks to all reels being activated for splits. It adds up to a great experience that puts a twist on ‘Book of…’ slots, so it’s a slot you don’t want to miss at the newest online casinos.
