Evoplay Launches The Castle of Slotenstein Halloween Slot

Evoplay has added a Halloween-themed title to its portfolio with The Castle of Slotenstein, a Frankenstein-inspired slot featuring three distinct boosters and a Hold & Win bonus built around collecting symbols and unlocking prizes.

Set inside a sinister castle, the game introduces a mad scientist and his towering creation, with players pursuing wins through a series of special features.

Three pumpkin-shaped Bonus symbols in different colours activate individual boosters, each influencing how the bonus round develops.

The Green Shock symbol increases the number of spins available at the start of the Bonus Game from three to four. Purple Trick symbols can add Bonus symbols to their reel or raise the values of symbols already present, up to 5x. Meanwhile, Blue Treat symbols transfer their values to every Orange Bonus symbol currently on the grid.

The Bonus Game opens with three or four spins, depending on which boosters are active. During the feature, the reels display only Bonus symbols.

Whenever a new Bonus symbol lands, the spin counter resets, extending the opportunity to fill the reels and increase the potential win.

Completing a reel with three Bonus symbols triggers a collection feature. Their values are added to the win meter, after which the completed reel is cleared. The first completed reel also unlocks one of five sections on the Grand Reel of Fortune, introducing a progression element to the bonus round.

Once all five sections have been unlocked, the Grand Reel of Fortune awards a final spin with one of eight possible outcomes. These include multipliers of 2x, 3x, 5x and 8x, as well as Mini, Mega, Super and Grand prizes.

Players who prefer immediate access can purchase the Bonus Game through the Bonus Buy feature. They can choose to activate one, two or all three boosters when entering the round.

Ivan Kravchuk, CEO at Evoplay, said: “The Castle of Slotenstein, gives the classic Frankenstein story an Evoplay twist, combining a spooky Halloween setting with a feature set designed to keep the action building. The three boosters each change the way the Bonus Game develops, while the Grand Reel of Fortune gives players a target to chase as they work through the feature. It makes for a suitably unpredictable addition to our portfolio just in time for the scary season.”
