Page updated July 2026
Book of Books, from Peter Sons, follows the long tradition of Book-style slots that trace back to the genre's earliest days, delivering the expected expanding pay-anywhere symbols during Free Spins alongside a handful of twists that give the game its own personality. Notably, it skips the pyramids entirely in favour of a wooded, medieval-looking land where pointed trees sway and a trio of musicians play homemade instruments in the background.
That woodland setting marks Book of Books out as a fairly distinctive entry in a genre otherwise dominated by Egyptian temples, giving it a fantasy-adventure feel rather than a desert-treasure one. Played on a 5-reel grid with a flexible paylines structure running from 10 up to 40 depending on how far the grid expands, wins form from at least three low-pay symbols or two premiums landing left to right. A Golden Bet option increases stakes by 50% in exchange for a better chance of triggering the bonus game.
Book of Books offers a maximum return to player of 96.1%, a strong figure for the genre, though lower RTP versions may be available depending on the operator, so it's worth checking which model is live before playing.
Rated high volatility, the game's listed hit frequency of 33.26% suggests winning spins land roughly one in every three, a genuinely active pace for a high-volatility title and a sign that the base game keeps players engaged between the bigger bonus-driven wins.
The maximum win sits at 10,000x the stake, a strong ceiling that rewards the grid-expansion mechanic as it grows from 5x3 up to as large as 5x5 with 40 paylines. Stakes run from 0.10 up to 50 per spin, keeping the game accessible while leaving room to chase that five-figure multiplier.
Book of Books rewards players who appreciate a genre classic executed with real visual personality, thanks to its woodland setting and expanding grid mechanic. With a 96.1% RTP, a healthy 33.26% hit frequency and a 10,000x ceiling, it's a well-rounded pick for high-volatility fans.
