Possessed by NoLimit City

This game invites you to spend the night in a house of horrors, packed with creepy icons, an animated background, and a disturbing soundtrack. The slot looks quite eerie, with the inverted cross bursting into flames and the ghostly figure appearing behind the reels just for a few seconds after each spin.

The high-paying icons are called the xCrucifix in this game: an obsessed woman, a priest, a sphynx cat, and a monster/man. Here are the features triggered by these symbols:

• xActivation feature, during which the icons in the inverted cross get replaced with the xCrucifix.
• Wild and xNudge Wild, which appear only in the middle row. If the wild symbol lands on the cross’s joint, all the icons inside of it become Wilds, providing you with a 2x multiplier. If the Wild appears in any other position within the cross, the entire middle row gets transformed into Wilds, providing you with a corresponding multiplier.
• xWays and Infectious xWays, both converting 2-3 icons into similar-paying ones. The Infectious xWays additionally stretch to adjacent symbols, expanding them to the same size.

Besides, the slot has three free spin rounds with specific features.

The Possessed slot’s RTP is 96.06% and volatility is high.

The Lost Boys by Blueprint Gaming

Released in August 2024, this new slot is themed around the same-name 80s horror/comedy movie of the same name. Aside from the main characters depicted on the high-paying icons, the reels are filled with the J-A low-paying symbols. The features include:

• Wild symbols substituting for other icons;
• Scatter icons triggering free spins;
• The Cash Collect feature, which allows you to increase your wins depending on the landed symbols;
• Modifiers, which appear randomly on any spin as extra Cash symbols, extra Scatters, or extra Wilds;
• the Rapid Fire Jackpot feature, which allows you to trigger one of five jackpot options.

The game has a medium/high volatility and an RTP of 95.00%.

Undead Fortune by Hacksaw Gaming

The slot is themed around Ancient Egypt but in a horror-like manner. The game allows you to immerse in a cursed Egyptian tomb, with its reels filled with the icons of different gods turned into zombies. The backdrop with different monsters and an eerie soundtrack are also well-thought-out, contributing to an overall atmosphere.

Special features are the following:

• Wilds, replacing all the other symbols to form winning combinations;
• VS Duels: Walk fills an entire reel and triggers a battle with a monster to win a multiplier. If you win, the symbol moves left each spin to play again until you lose;
• VS Duels: Expand acts similarly to Walk but expands instead of moving across the reels;
• The Curse Free Spins Bonus with 10 free spins.

The RTP of the Undead Fortune slot is set at 96.29% and the volatility is high.

Eldritch Dungeon by Print Studios

The game is designed around the Dungeons & Dragons tabletop role-playing game. Its backdrop and special features, symbols, and music are designed to contribute to the dark fantasy atmosphere. Eldritch Dungeon features an 8×8 playing grid with a cluster pays system. The game is a perfect mixture of fantasy role-playing games and traditional slots.

Once having launched the slot, you should pick one of the three characters, each with specific abilities that impact the gameplay. 

The bonus features are:

• The Dungeon Battle, where your character faces increasingly difficult enemies and collects Spectral Keys.
• The Treasure Hall Spins allow for unlocking positions with the collected Spectral Keys, where landing and merging coins provide solid rewards.

Eldritch Dungeon is a highly volatile game with an RTP of 96.10%.
