Book of Horror

Book of Horror by Spinomenal is a 5-reel, 10-payline video slot built around the classic “book” mechanic and a horror-theme inspired by haunted tomes, grim potions, glowing pumpkins and eerie witch motifs. The game’s main feature is its Free Spins round, triggered when three or more Book symbols (which act as both wild and scatter) land anywhere on the reels. When Free Spins begin, one regular symbol (excluding the Book) is chosen to become the Expanding Symbol, which during the free spins can stretch to cover full reels—even if its instances are not adjacent—greatly increasing the chance of wins. If three or more Book symbols appear again during free spins, this retriggers another set of ten free spins. The Book symbol also substitutes for other symbols in paying combinations outside of the free spins. Book of Horror includes a Buy Feature allowing players to skip directly to the Free Spins mode by purchasing it. The maximum potential win in Book of Horror is up to 5,000× the stake. The visuals are dark and atmospheric, the soundtrack complements the chilling theme, and the gameplay sticks to a fixed layout so every spin uses all ten lines.

You can try it for free in demo mode or play it for real money.
