Merlin’s Grimoire uses symbol splitting to change the number of positions evaluated on each reel. The effect begins across only part of the base layout, then can extend over all five reels during free spins. Its advertised 7,776 ways is therefore a feature-state ceiling, not a fixed count attached to every ordinary spin.

| Main features | During free spins, the splitting effect can extend across all five reels and lift the possible ways count to 7,776. The phrase “up to” matters because it identifies the maximum expanded state rather than the configuration of every feature spin. The official page compares the idea with Book of Dead-style expanding symbols, but splitting symbols into more positions is not the same action as filling a reel with one selected symbol. The review therefore preserves the provider’s own distinction. The mechanical progression is spatial: three affected reels in ordinary play can become five affected reels in the feature. That changes both the visible grid and the number of evaluated routes without introducing an unsupported persistent multiplier. Power of Merlin Megaways provides a useful thematic comparison, although Megaways varies symbol counts |
RTP and stake limits can vary by version and market. Check the information screen in the game you open. Maximum win is a ceiling, not an expected result.
How Merlin’s Grimoire sets up the base game
The official page describes a video slot in Play’n GO’s Arthurian Legend series. Its central Expanding Symbol or Symbol Splitting feature starts by covering three reels in the base game. Splitting creates additional symbol positions and consequently more possible ways to form combinations. The public explanation does not state the ordinary row arrangement or the exact trigger sequence for every split, so those details are not reconstructed from another book-style title. A larger evaluation area also does not guarantee a winning combination.

During free spins, the splitting effect can extend across all five reels and lift the possible ways count to 7,776. The phrase “up to” matters because it identifies the maximum expanded state rather than the configuration of every feature spin.

How the mechanics interact
The mechanical progression is spatial: three affected reels in ordinary play can become five affected reels in the feature. That changes both the visible grid and the number of evaluated routes without introducing an unsupported persistent multiplier. Power of Merlin Megaways provides a useful thematic comparison, although Megaways varies symbol counts through its own reel system. Here the documented focus is the controlled spread of splitting across the reels.
Configuration, strengths and limitations
Play’n GO dates the release to 7 July 2022 and explicitly categorises it under Arthurian Legends and Fantasy. The public product page does not list RTP, volatility, paylines in the base state or a maximum-win multiple, so the information panel of the exact installed version remains authoritative. The strength is a visually understandable escalation in reel coverage. The limitation is that the published summary gives less numerical detail than some newer game pages, making false precision particularly easy.
Merlin’s Grimoire earns its identity through the movement from partial to full-reel symbol splitting. The rule provides a clear feature escalation and a concrete upper ways count without needing to borrow mechanics from another Merlin game. Readers should focus on how the board expands, not assume that the word Grimoire makes it a conventional selected-symbol book slot. Its strongest quality is visible structural change; its limitation is that expanded routes remain opportunities and still require matching symbols to produce a result.
