Grimoire Slot Features

Grimoire combines cluster wins, respins, Free Spins, Ink Magic, and Mystery into a layered system with page turns, growing multipliers, and multiple ways to reach bonus play.

Cluster Wins

Grimoire pays on clusters of 5 or more matching symbols connected horizontally or vertically, including across the spine between pages. Diagonal contact does not count. Separate clusters pay separately, and every winning board triggers a free page turn before the next respin.

Free Spins

The Free Spins symbol triggers the bonus system and does nothing by itself. 3 symbols start the Bonus, 4 start the Super Bonus, and 5 or more start the Hidden Bonus. Inside a bonus, 2 symbols award +3 spins and 3 or more award +5.

Bonus

The Bonus starts directly with 10 free spins when bought or triggered. The multiplier resets to x1 at the start of every spin, then rises by one on each respin. That creates steady progression during the round, with cluster wins amplified by the current multiplier.

Super Bonus

The Super Bonus also starts with 10 free spins, but its multiplier behaves differently. It begins at x1 and never resets during the bonus, so every respin continues building the same multiplier. This makes the round more explosive than the standard Bonus.

Ink Magic

Ink Magic only activates inside a bonus. Every symbol position in a winning cluster pours ink into the flask, counted once per board, and every 20 positions fill it, with the leftover carrying on to the next board. A filled flask rains its Wilds onto the next board, and those Wilds never cover a Free Spins symbol or another Wild.

• Bonus: each filled flask rains 3 Wilds.
• Super Bonus: each filled flask rains 5 Wilds.
• Hidden Bonus: each filled flask rains 7 Wilds.

Mystery

Mystery is an armed mode that resolves to a random outcome on each spin. A bonus awarded this way has no guaranteed minimum, and both the Super Bonus and the Hidden Bonus can return less than the Mystery cost. The board can still win and respin in every outcome.

• 70% no bonus: 2 Free Spins symbols.
• 20% Super Bonus: 4 symbols.
• 10% Hidden Bonus: 5 symbols.

Bonus Buy

The Feature Menu holds three armed modes, charged on every spin until they are switched off, and two direct bonus buys.

• Extra Bet: x3 the bet per spin; higher bonus trigger chance, with wins still calculated from the base bet.
• Inkmagic Spin: x500 the bet per spin; every spin opens with 9 Wilds and a starting multiplier from x2 to x100, and no bonus can start in this mode.
• Mystery: x500 the bet per spin; random outcome that can award no bonus.
• Bonus: x100 the bet; starts 10 free spins.
• Super Bonus: x250 the bet; starts 10 free spins.

Grimoire Slot Review

Grimoire wraps its action in a dark fantasy spellbook setup, and the open pages give the slot a clear identity from the first spin. The candlelit desk, glowing symbols, and wizard framing work with the cluster board format instead of sitting on top of it, so the theme matches the mechanics closely.

The standout is the way respins and multipliers build from every win, then branch into Bonus, Super Bonus, Mystery, and Ink Magic. That structure adds genuine depth, but the game still leans hard into high volatility, with the same theoretical RTP across every mode.

Grimoire offers bonus rounds and multiplier growth, but longer sessions and feature buying do not improve its theoretical RTP. The 20,000x cap gives it a serious ceiling, yet the 6×6 cluster format and multiple paid modes keep it demanding. The overall package is confident, but not gentle.
