The Castle of Slotenstein

Evoplay presents The Castle of Slotenstein, a video slot featuring a layout of 5 reels and 3 rows, along with 20 fixed paylines. The game immerses players in a dark theme reminiscent of Frankenstein and Halloween, drawing inspiration from a mad scientist's castle adorned with glowing pumpkins. In the base game, players will encounter regular symbols that depict gothic lab tools and various creatures, while a Wild symbol styled like the Frankenstein monster can be found on reels two through five to assist in forming winning combinations.

Within the base game, there are three distinct Bonus Pumpkin symbols: Green “Shock”, Purple “Trick”, and Blue “Treat”. Landing one to three of these symbols may activate the bonus round, while four or more will guarantee entry. Each pumpkin type triggers a unique booster during the bonus round: Shock increases the respins from three to four, Trick allows Purple pumpkins to enhance existing Orange values in their column and fill empty spaces before transforming into Orange, and Treat adds its value to all Orange Bonus symbols across the grid.

When the Bonus Game commences, only Bonus symbols will appear on the reels, with new symbols resetting the respin counter. Orange Bonus symbols feature random values ranging from 0.5× to 5× your bet. Filling all symbols in a column collects their value for your win meter, clears that column for new symbols, and unlocks one of five locks surrounding the Grand Reel of Fortune. Once all columns have been filled at least once during the bonus, players receive a spin on the Grand Reel of Fortune, which can yield multipliers (2×, 3×, 5×, or 8×) or fixed tiered prizes labeled Mini, Mega, Super, or Grand.

Additionally, The Castle of Slotenstein includes a Bonus Buy feature, allowing players to bypass directly to the Bonus Game. Through this option, players can enter with one, two, or all three boosters pre-activated, with costs displayed in their selected currency. The game is characterized by high volatility and a feature set that emphasizes value enhancement through its layered boosters, collection mechanics, and the Grand Reel finale, focusing more on building toward the bonus rounds rather than frequent wins in the base game.
