Pumpkin Boosters and Bonus Game Explained

Central to the action in The Castle of Slotenstein are three unique pumpkin Bonus symbols that land across all reels in the main game: the Green Shock pumpkin, the Purple Trick pumpkin, and the Blue Treat pumpkin. Landing one to three of these symbols in a single spin provides a random chance to trigger the Bonus Game, while four or more bonus symbols guarantee immediate entry into the round.

The feature functions as a collection respin round where regular symbols are removed, leaving only empty positions and value-bearing symbols. The active boosters correspond directly to the pumpkin colors present on the triggering spin:

- Shock Booster: Activated by the Green pumpkin, this modifier expands the starting respin counter from three to four spins, extending the longevity of the bonus round.

- Trick Booster: Triggered by the Purple pumpkin, this brings in Purple symbols that augment every Orange symbol on that reel by adding their credit value, then fill open spots on that reel with matching Orange symbols before turning Orange themselves.

- Treat Booster: Sparked by the Blue pumpkin, this causes Blue symbols to enhance all Orange symbols across the grid by adding their value to each one.

Grand Reel of Fortune

During the collection sequence, Orange Bonus symbols land with multiplier prizes ranging from 0.5x to 5x the bet. Completely filling all three vertical positions on any single reel tallies those locked prizes into the win meter, wipes that column clean so more symbols can drop, and unlocks one of five segments of the Grand Reel of Fortune. Unlocking all five segments grants access to the prize wheel, providing the opportunity to reach the slot's maximum win ceiling of 3,128x.
