Merlin's Grimoire Slot Overview
Merlin’s Grimoire is a video slot from Play'n GO built on 5 reels with 3-6 rows and 243 ways from the start. Split symbols can lift the count to 7,776 ways. From a math perspective, the numbers tell you this is a very high-volatility model with a 96.20% default RTP, 0.10 to 100 stakes, and a 30,000x maximum win.
Merlin's Grimoire Slot Information
Regular symbol values are modest, which is typical for a bonus-led profile. Five low symbols pay 0.8x to 1x the bet, while the premium set, scroll, blue potion, staff and Merlin, pays 2.5x to 4x for five of a kind. Looking at the paytable structure, premium symbols can also form wins from two matches, which helps keep some base-game activity alive.
Book is both Wild and Scatter, and it pays the same as the top Merlin symbol. Wins are formed by landing 3 or more matching symbols on adjacent reels from the far left. I think the base game can drag a bit because raw symbol values are not carrying the experience, the feature layer is.
Symbol Payouts
Merlin's Grimoire Slot Features
Splitting Reels are the key structural mechanic. In the base game they can only activate on reels 2, 3 and 4, while in free spins they can appear on all reels. If a split symbol is part of a win, the payways for that win are doubled. From a math perspective, that pushes most of the upside into feature-enhanced outcomes rather than steady base returns.
Wild Scatter can land on any reel, substitutes for other symbols, and 3 or more trigger Free Spins. The feature starts with 10 free spins. Land 3 or more Wild Scatters again and you get 10 extra spins, up to 5 re-triggers. Before the round starts, one special expanding symbol is selected for the whole feature.
Expanding Symbol is where the top-end potential comes from. When the chosen symbol is part of a win, it expands to cover full reels and does not need adjacent reel positions to create more combinations. Combined with split reels, the bonus explains how the game reaches 30,000x, but bonus access is the gating factor.
Bonus Buy Options
Split symbols can appear randomly. In the base game they can land on reels 2, 3 and 4, and in free spins they can land on all reels. A winning split symbol doubles the payways for that win.
Triggered by 3 or more Wild Scatter symbols. Awards 10 free spins, with 10 extra spins for each re-trigger. Re-triggers can happen up to 5 times, and one expanding symbol is chosen before the round starts.
A special symbol is randomly selected for the whole free spins round. When it forms part of a win, it expands to cover the full reel and does not need adjacent reels to create extra winning combinations.
The book symbol substitutes for other symbols and also triggers free spins when 3 or more land anywhere.
Ryan Cole’s Verdict
Merlin's Grimoire Slot Conclusion
Merlin’s Grimoire keeps the familiar expanding-symbol formula, then adds split reels to increase combinational reach from 243 to 7,776 ways. The numbers tell you the design is bonus-centric, with very high volatility and a top win of 30,000x. If you like long-term upside more than frequent cash flow, the model makes sense.
I am not entirely sold on the fact that the base game feels close to older Book-style releases, even with the split-reel upgrade. Still, the bonus package is stronger than it first appears, and the RTP is solid if you get the 96.20% version.
