Book of Cthulhu

Book of Cthulhu by Kagaming is a video slot with the classic "Book" format, featuring five reels and three rows. The game uses 20 fixed paylines on which combinations of symbols are paid out. The theme is heavily inspired by Lovecraftian horror: you will find ancient books, tentacles, mystical symbols, and dark creatures that take you to the depths of the ocean. The book symbol serves as both a Wild (replacing other symbols) and a Scatter (trigger for the bonus).

Landing three books or more in the base game starts the Free Spins feature with ten free spins; four or five scatters award fifteen or twenty-five free spins, respectively. During the free spins, one symbol is randomly chosen as the Expanding Symbol; each time this symbol lands on the reels, it expands across the entire reel and pays out even when the positions are not adjacent. There is no Bonus Buy option available – you must earn the free spins through the regular gameplay mechanics.

The slot does not have separate bonus rounds outside of the free spins, nor are there multipliers outside of the Expanding Symbol feature. Bets vary by provider, and the maximum win depends on how many and which symbols you land during the Free Spins. The visuals and audio contribute to the grim atmosphere, with dark colors, mysterious artwork, and a suffocating feeling that fits well with the theme. Book of Cthulhu does not offer a progressive jackpot.

You can play it for real money.
