With an Arthurian Legend theme, the Merlin’s Grimoire slot is part of the expansive series by Play ‘n GO. Following on from the likes of Rise of Merlin, the game is based on Merlin in his younger years before becoming the wise wizard he is known for today. Merlin’s aim is to find the ancient book of spells, the Grimoire, which holds the secrets to the art of magic.

Set in a dark and creepy forest, you’ll see the stone reels covered in moss. With a mystical feel, there’s a movie-like soundtrack stirring as you spin the reels. On the reels you will see 6 icons from Merlin’s Circle. You have Mind, Elements, Motion, Matter, Transformation and Time icons. The higher value symbols include scrolls, potion bottles, gem sceptres and Merlin. Merlin is the best paying symbol with 2, 3, 4 or 5 awarding 0.4, 0.8, 1.6 or 4 x your total bet.

The Grimoire is the wild scatter. Substituting for all symbols, it also pays up to 4 x your total stake for 5 in combination. 3 or more will trigger the Free Spins feature (more details below).

Merlin’s Grimoire Mobile

Play ‘n GO create all slot games with HTML5 technology. This allows for play on mobile, tablet and desktop devices. Merlin’s Grimoire is no difference. With the splitting symbols and up to 7,776 ways to win, it’s recommended you play on a laptop or PC for the best visual experience.

Merlin’s Grimoire Bonus Features

The Merlin’s Grimoire slot benefits from 2 bonus features. The 3 middle reels can give you Splitting Symbols in the base game which can result in 1,944 ways to win. In the Free Spins feature, you can play with unlimited free spins as well as a special expanding symbol. All 5 reels can contain Splitting Symbols which can result in up to 7,776 ways to win.

Splitting Symbols feature

Above the 5 reels, you will see Thunderbolt icons. When any of the Thunderbolt icons on the 3 middle reels light up, the Splitting Symbols feature will be activated. The reels with a lit Thunderbolt icon will see all symbols on the active reel splitting into 2.

With 3 positions on each reel, each of the 3 middle reels could contain 6 symbols each. If all 3 middle reels are lit, this would result in a maximum of 1,944 ways to win on each base game spin (3x6x6x6x3).

Free Spins feature

merlins-grimoire-slot-free-spins feature

The Free Spins feature is triggered when landing 3 or more Grimoire wild scatters anywhere on the reels. With 10 free spins awarded, all 5 reels can benefit from the Splitting Symbols feature. The Thunderbolt icon can randomly light up on all 5 reels as opposed to the 3 middle reels in the base game.

If all 5 reels have a lit Thunderbolt icon, you will have 6 symbols on each of the 5 reels. This can lead to 7,776 ways to win (6x6x6x6x6).

Like classic ‘Book of’ slots, 1 symbol is randomly chosen to become the special expanding symbol. If that chosen symbol can create a winning combination, it will expand to take over the whole reel.

Furthermore, payouts are scatter style and don’t need to appear on adjacent/successive reels. The higher the value of the special expanding symbol, the bigger your potential payouts. Here’s what each symbol can pay at a maximum:

Symbol(s) Max Payout
Mind, Elements + Motion 6,220.8 x bet
Matter, Transformation + Time 7,776 x bet
Scroll + Potion Bottle 19,440 x bet
Gem Sceptre 23,328 x bet
Merlin 31,104 x bet

Finally, landing 3 or more Grimoire wild scatters will result in a retrigger and 10 more free spins. There’s no limit to how many free spins can you win.

Originality








The Merlin’s Grimoire slot goes in another direction to previous slots in the Arthurian Legend series. Well designed as usual, Splitting Symbols have appeared in previous Play ‘n GO slots such as Forge of Gems. In the base game, up to 1,944 ways to win are possible.

However, the action heats up in the Free Spins feature. With a special expanding symbol, all 5 reels have the potential to display Splitting Symbols. This can lead to 7,776 ways to win on each free spin. If you combine 7,776 ways to win with the high value Merlin as the special expanding symbol, payouts of 31,104 x bet are possible on every free spin.

This makes Merlin’s Grimoire stand out against typical ‘Book of’ slots that normally offer 5,000 x bet payouts (i.e. Play ‘n GO’s very own Book of Dead). Comparing to other slots in the series, Merlin’s Grimoire stacks up pretty well:

Slot RTP Max Win
Merlin’s Grimoire 96.2% 31,104 x bet
Rise of Merlin 96.58% 5,000 x bet
Lord Merlin and the Lady of the Lake 96.2% 10,000 x bet
Merlin and the Ice Queen Morgana 96.2% 20,000 x bet

Merlin’s Grimoire will also appeal to fans of Nolimit City slots who use an xSplit mechanic. Games like Tombstone RIP and Remember Gulag offer it.

Pros
  • 31,104 x bet max wins
  • Splitting symbols in base game + free spins
  • Combines splitting and special expanding symbols with free spins
Cons
  • Extremely high volatility
