Book of Lilith — RTP, volatility and max win

Book of Lilith by Spinomenal is a book slot with skulls and devilish imagery in red, on a 6×3 grid with 10 paylines, and comes out at RTP 96.01%, high volatility and max win 10,000×. The book symbol, expanding symbols in the free spins and a feature buy shape the game.

The game was released on October 23, 2025. Hell is not a backdrop here but the subject: the book, the skulls and the devilish figures carry the theme. With six reels the grid is wider than a standard five-reel game, and besides the free spins you can use the feature buy to go straight to the bonus round. Stakes range from €0.10 to €100.

In the Book mechanic one symbol is wild and scatter at the same time: it completes combinations and triggers the bonus round. In free spins a symbol is picked that can expand; such an expanding symbol then fills a whole reel. Scatters pay wherever they land on the reels. With the feature buy you purchase direct access to the bonus round instead of waiting for it to trigger. The base game centres on paylines, the bonus on expanding symbols.
