Cluckin Grim Slot Features

The Reap, Soul Harvest, The Grim Reaper, Free Spins, and Buy Bonus all shape Cluckin Grim, combining cluster wins, soul collection, board resets, and buyable bonus paths into one layered feature set.

The Reap

Winning clusters trigger The Reap, which removes those symbols from the board and lets new ones fall in from above. If the drop creates another win, the process repeats. This gives the game a cascading structure and keeps each spin active until the board stops paying.

Soul Harvest

Soul Harvest works alongside every reap. Each removed symbol can leave a soul behind, which flies to the soul collector. The collector holds 5 souls, and in the base game it starts empty every round. That gives the feature a clear build-up before the Reaper enters.

The Grim Reaper

When the soul collector fills, The Grim Reaper arrives, empties it, and targets 3 to 6 symbols on the board. Each chosen symbol becomes Wild or gets a multiplier mark of x2, x3 or x5. Marks stay in place for the rest of the round and add together on the same cell.

Free Spins

Free Spins start when Graves land on the first board. 3 Graves trigger Reaper Spins, 4 trigger Harvest Moon, and 5 trigger The Grim Hour. In free spins, Wilds appear more often, Graves do not land, and each mode has its own starting Wild minimum and rules for retaining souls and marks.

Reaper Spins

Reaper Spins awards 8 free spins, each starting with at least 4 Wilds on the board. The soul collector empties after every spin, so the round resets more often. This creates a faster-paced free-spin mode with strong early board support.

Harvest Moon

Harvest Moon awards 10 free spins, each starting with at least 2 Wilds on the board. Souls and multiplier marks stay active from spin to spin until the feature ends, so each round can build on the last one rather than resetting completely.

The Grim Hour

The Grim Hour awards 10 free spins, each starting with at least 1 Wild on the board. Souls and marks carry over like Harvest Moon, and the Reaper marks the board before the first spin. His marks are doubled to x4, x6 and x10, which makes this the strongest setup.

Buy Bonus

Buy Bonus lets players purchase feature access and choose between different bonus paths.

• Soul Boost: x2 the bet per spin; doubles play amount and increases soul collection.
• Reaper Spins: x100 the bet; 8 free spins with at least 4 Wilds.
• Harvest Moon: x200 the bet; 10 free spins with at least 2 Wilds.
• Mystery Bonus: x100 the bet; one spin with one of four results.

Cluckin Grim Slot Review

Cluckin Grim stands out with a gothic barn, a skeletal rooster Reaper, and a playful horror look built from skulls, scythes, lanterns and feathers. The art gives the slot its identity without leaning on anything outside the screen, and the cluster format keeps every board full of moving parts.

The strongest mechanical point is The Reap, which clears winning clusters and drops in fresh symbols for more wins. That links directly to Soul Harvest and the 5 soul collector, while High volatility and the 10,000x max win set clear expectations for swings and session planning.

Cluckin Grim can chain wins and build souls to summon the Reaper for Wilds and multiplier marks, while Graves on the first board trigger free spins. The free spins modes add the real value, especially when souls and marks carry forward, but the base game still feels like the engine that feeds those features. Layered, volatile.
