The game is set in a dark and ancient forest, where Merlin is seeking out a powerful grimoire (spellbook). The theme is mystical and atmospheric. The graphics are stunning, with a detailed and slightly gritty art style that gives the world a sense of ancient magic. Animations are magical, with glowing runes and powerful spell effects. The soundtrack is a haunting and epic orchestral score that perfectly captures the mystery and power of the theme.

  • Regular Symbols: Magical runes are the low-paying symbols. The high-paying symbols are a scroll, a potion bottle, the grimoire itself, and the powerful wizard Merlin.
  • Special Symbols:
    • Wild/Scatter Symbol: The Grimoire acts as both the Wild, substituting for all other symbols, and the Scatter, triggering the free spins.

To start casting spells, select your bet from $0.10 to $100. Press the spin button to see what the grimoire reveals. The game is packed with unique mechanics, so trying the free slot machine demo is a wise move. This mobile slot is fully optimized for a flawless magical experience on any device.

Splitting Symbols

Above reels 2, 3, and 4 are special positions. On any spin, these positions can activate, causing all symbols on the reel below to split into two, increasing the number of ways to win from 243 up to 7,776.

Free Spins with Expanding Symbol

Landing 3 or more Grimoire Scatters triggers 10 free spins. Before the round begins, a random symbol is chosen to be the special expanding symbol. During the feature, the Splitting Symbols mechanic is active on all five reels. When your special symbol lands, it will first split if the reel is active, and then all instances will expand to cover their entire reels, creating the potential for massive, screen-filling wins. The feature can be retriggered for more spins.


RTP: The RTP of 96.20% is a solid, industry-standard rate that offers a fair magical quest.

Volatility: This is a very high volatility game. The gameplay is all about the explosive combination of splitting reels and expanding symbols in the free spins round. This powerful synergy can lead to the game’s colossal 30,000x max win, making it a perfect choice for players seeking immense magical power.
