Grimspell Slot Features

Grimspell mixes wild multipliers, expanded Wild columns, Free Spins, and multiple buyable modes, giving the Activ slot a layered structure where each feature changes how the reels behave and how wins build across the board.

Witch Coven

Witch Coven is a per-spin mode that guarantees 2-3 blue, red, or orange Wilds before they expand. It stays active until you switch it off in the store, so it works like a controlled setup for players who want steady feature pressure rather than a random trigger.

Twin Coven

Twin Coven runs on a per-spin basis and guarantees at least two expanded Wild columns on every spin. Those columns can carry multipliers from 5x to 200x, and up to five columns can land, which gives the mode a strong escalation curve without using Free Spins.

• Guaranteed two expanded Wild columns: starts every spin with feature coverage.
• 5x to 200x column multipliers: adds the main win potential.
• Up to five columns: creates extra overlap across the reels.

Triple Coven

Triple Coven follows the same structure as Twin Coven, but it guarantees at least three expanded Wild columns each spin. It also uses 5x to 200x column multipliers and can still land up to five columns, making it the strongest store mode for raw board coverage.

• Guaranteed three expanded Wild columns: increases feature density.
• 5x to 200x column multipliers: drives line win value.
• Up to five columns: keeps room for larger combinations.

Bonus

Bonus starts when 3 Bonus symbols land, or when you buy it from the Bonus Store. It gives 8 Free Spins, adds about 3-4 Wilds per spin, and keeps Wilds for one extra spin, so the feature builds momentum across the round.

Super Bonus

Super Bonus triggers with 4 Bonus symbols or through Mystery Bonus, then awards 10 Free Spins. It usually drops about 4-5 Wilds per spin, with values up to 10x, and those Wilds stay for one extra spin, which gives the feature stronger carry-over.

Epic Bonus

Epic Bonus activates with 5 Bonus symbols or Mystery Bonus and gives 12 Free Spins. It tends to land about 5-6 Wilds per spin, with values up to 25x, and those Wilds stay for two extra spins, which makes the round feel more persistent.

Hidden Bonus

Hidden Bonus triggers with 6+ Bonus symbols or Mystery Bonus and awards 15 Free Spins. It brings in 6+ Wilds per spin, with 25x-100x common, and those Wilds stay for two extra spins. That makes it the most aggressive bonus in the set.

Mystery Bonus

Mystery Bonus is a one-time buy feature that always charges the price, then gives a random outcome. It can produce no bonus, Bonus, Super, Epic, or Hidden Bonus, so the result depends on the roll rather than a fixed feature path.

• No bonus: returns nothing useful.
• Bonus: awards 8 Free Spins.
• Super: awards 10 Free Spins.
• Epic: awards 12 Free Spins.
• Hidden: awards 15 Free Spins.

Grimspell Slot Review

Grimspell leans hard into its Halloween fantasy identity, and the gothic layout gives the reels a clear purpose rather than just decoration. The moonlit forest, haunted castle backdrop, and glowing pumpkin symbols create a defined look, while the sound and pacing feel shaped around its magical coven theme.

The real draw is the feature set, especially the wild multipliers and the expanded Wild columns in Witch Coven, Twin Coven, and Triple Coven. Grimspell asks for commitment through per spin modes and pricey bonus buys, so the experience suits players who accept volatility and want the board to escalate through layered Wild interaction.

Grimspell suits players who like buying into control and chasing a top end of 40,000x without drifting into cluster gimmicks or ways systems. The 96% RTP helps, but the game still feels best for experienced slot players who enjoy mechanic depth and can handle a high volatility swing pattern.
