The wizarding world is a hugely popular theme in the slots world, but Merlin’s Grimoire is one game that stands out from the crowd. The Split Symbols feature brings a whole new dimension to the base game, with your ways of winning being increased each time it is activated.

That feature may be unique, but the real excitement comes when you trigger the Free Spins Bonus. The special expanding symbols expand to cover an entire reel each time they feature in a win, which can deliver some incredible wins.

With this being a high volatility slot machine, you may have to be patient and wait for those base game wins and bonus round triggers, but the increased payouts means they could well be worth the wait.

How To Play Merlin’s Grimoire Slot

As with all games from Play ‘n’ Go, Merlin’s Grimoire offers clever graphics and a dramatic soundtrack. The base game is played on a 5×3 reel grid, with 243 paylines available on each spin.

The lower-paying symbols runes placed on six different coloured tokens. These symbols are balanced out by higher-paying symbols that appear as Potion, Scroll and Staff symbols.

Merlin appears as the highest-value symbol in this game, paying out 4x your coin size each time you land five matching symbols.

The special symbol in this game is the Grimoire himself. A Grimoire is a book of spells that acts as both a Scatter and a Wild symbol. If one or two Grimoires spin onto the reels, they will act as standard Wild symbols, replacing other symbols to complete wins where possible.

Merlin’s Grimoire Slot Features

Merlin’s Grimoire is an action-packed slot game that offers the unique Splitting Symbols feature, as well as a lucrative Free Spins Bonus.

Splitting Symbols

Splitting Symbols is the feature that makes this game unique. In the base game, this can appear on reels 1-3 when the reels are active. The symbols on those reels are then split into two, with the number of ways of winning increased.

Free Spins Bonus

Landing three or more of those Grimoire symbols will see them act as Scatter symbols and in turn trigger the Free Spins Bonus and award an initial 10 free spins.

You will also be awarded a cash prize of up to 4x your coin stake, depending on the number of Scatter symbols you collected.

Merlin’s book will then appear to reveal which of the regular symbols has been chosen to become the special expanding symbol. This expands to cover the entire reel on each win it appears in during the bonus round, which can lead to huge wins.

The Split Symbols feature can also come into play in this bonus round, boosting your number of ways to win up to an incredible 7,776.

Landing three or more Scatter symbols during this bonus round will re-trigger it and award additional free spins. Each time this occurs, a new special expanding symbol is chosen.
