Our take
Inspired Gaming's Halloween-themed book slot with 96.23% RTP, high volatility, and free spins with expanding symbol mechanics.
Book of Halloween is Inspired Gaming's seasonal entry into the book-slot genre, and whilst it doesn't break mechanical ground, the 96.23% RTP makes it a more player-friendly option than many alternatives. High volatility means wins cluster in bonus rounds rather than trickle through base games.
The structure is familiar: 5 reels, 3 rows, 10 paylines, with the book acting as wild and scatter. Trigger free spins with the scatter, and you'll unlock the free-spins feature where one randomly selected symbol expands on each spin. This expansion drives cascading wins and keeps the bonus round engaging. The 200× multiplier on max free-spins outcome is a nice touch if conditions align.
Thematically, the game nails Hallowe'en atmosphere—graveyards, zombies, pumpkins, and a creepy yet readable design. It's not pushing artistic boundaries, but it fits its holiday window. The gamble feature exists if you want to double a win, though it's optional.
