Merlin’s Grimoire (Play’n GO) – Review & Demo Play

Merlin's Grimoire Slot Overview

Merlin’s Grimoire is a Play’n GO video slot with 5 reels and 3–6 rows, starting on 243 ways to win. Symbols can split, pushing ways up to 7776. Stakes run from 0.10 to 100 per spin. The default RTP is 96.20% with other settings in some lobbies. Volatility sits high, so swings bite. The setup leans on the ‘book of’ style yet adds splitting symbols and ways pays. The art drops young Merlin into a mossy forest with stonework reels and calm audio.

I form wins by landing three or more low pays, or two or more highs, on adjacent reels from the left. Base spins can light up the centre reels for splitting. The package feels focused, with fewer moving parts than gem-heavy titles. That suits fast sessions on mobile or desktop. It is a prequel take, so do not expect fireworks on every spin. The power comes when the core features collide.

Merlin's Grimoire Slot Information

Low pays are six rune-like tokens in green, blue, purple, orange, red, and yellow. Five of a kind returns 0.8–1x the bet. High pays show a scroll, a blue potion, a staff, and Merlin. Two are enough to start wins on the highs, with five-of-a-kind paying 2.5–4x. The book is both wild and scatter, and it pays like Merlin. Combine three or more matching symbols on adjacent reels from the left to trigger ways wins before any splitting kicks in.

Splitting Reels in Merlin's Grimoire

Splitting Reels can trigger on any base game spin on reels 2, 3, and 4. When active, any symbol landing on a lit reel splits into two. That simple move doubles symbol count on that reel and ramps the ways tally. With one, two, or all three centre reels splitting, ways can fly past the starting 243 and set up chunky connections. During the bonus, splitting can extend to all five reels, where the cap rises to 7776 ways.

Wild Scatter in Merlin's Grimoire

The Grimoire acts as wild scatter. As a wild, it substitutes for pay symbols to complete or extend ways wins. It can land on all reels. In practice, the wild tag helps stitch left-to-right connections when the grid falls just short. I have had tidy lines rescued by a single book in the middle, especially when splits were live.

As a scatter, three, four, or five books award 10 free spins plus a payout worth 0.8x, 1.6x, or 4x the stake. The symbol lands on any reel, so teases come often. I have seen runs with two books dropping again and again before the third hits. The trigger feels standard for the genre. The follow-up is where this slot moves beyond a basic book round, as splitting reels and expansions play off each other.

Free Spins in Merlin's Grimoire

Free spins come in fixed sets of 10. Land three or more books during the feature to add 10 more spins, up to five retriggers in total. That gives space for the engine to breathe. In this phase, all five reels can host splitting reels. The board widens fast when thunderbolt icons light up, so ways climb well past base game levels.

Before the round begins, one pay symbol is chosen at random as the special expanding symbol. When enough of that symbol land to pay, they expand to cover their reels and pay from any position. Adjacency is not needed. It mirrors classic book mechanics, then layers on splitting to double up the expanded stacks.

The best moments hit when expanding stacks appear on active splitting reels. That mix throws out screens where ways spike and wins flow without adjacent order. It takes a few aligned elements to land, so patience helps. When it clicks, the bonus can swing the session hard in one set of spins.

Expanding Symbol in Merlin's Grimoire

The expanding symbol sticks for the whole bonus. I have seen low pays chosen and trickle small wins often. High pays can be streaky, yet the ceiling climbs when they expand across several reels at once. Because expanded reels pay from anywhere, a three-reel spread can still deliver. Add splits on those reels and you get more symbol instances feeding the same pay. That synergy is the hook here.

Merlin's Grimoire Slot Verdict

Merlin’s Grimoire nails the mix of a ‘book of’ core with a fresh splitting twist. The flow stays readable, hits arrive in bursts, and the audio-visuals never grate. Volatility is high, so base play can feel sparse between features. The default RTP sits at 96.20%, though some sites run lower settings. Stakes from 0.10 to 100 keep it open to most bankrolls.

I rate it when I want a book slot with more texture and bigger way counts. The feature blend makes sense and the top end reaches up to 30,000x the bet. Triggers take time, yet the bonus has teeth when splits and expansions align. I keep it in rotation when I fancy a sharp, high-risk session with genuine punch.
