Book of Books Slot by Peter & Sons
Enter the secretive Order of the Peregrin in Book of Books, a high-volatility, medieval-fantasy slot from Peter & Sons. This adventure centers on dynamic panel resizing, collectible Powerups, and expanding symbols that can pay even on non-adjacent positions during Free Spins. With a base 5x3 grid and the potential to grow up to 5x5 and 40 paylines in the bonus, Book of Books turns every spin into a quest for knowledge, power, and treasure.
Core Gameplay At A Glance
- Base game: 5x3 with 10 paylines, paying left to right
- Wilds substitute all symbols except Scatters
- Scatters do not pay directly
- 2 Scatters in the base game award a Powerup (stored for Free Spins)
- High volatility with feature-rich Free Spins
Powerups: Collect, Store, And Supercharge Free Spins
Whenever you land exactly 2 Scatters in the base game, you earn one random Powerup that is saved for your next Free Spins round:
- +1 or +2 extra free spins
- An additional expanding symbol (up to 10 possible)
- Expanding symbol multiplier of x1 or x2 (multipliers stack additively)
All collected Powerups sit in the meter and activate together when Free Spins trigger.
Free Spins With Expanding Symbols And Panel Resizing
Trigger the bonus with 3 to 5 Scatters and get 7 Free Spins plus everything you have collected in the Powerup meter. The panel and paylines scale with your trigger:
- 3 Scatters: 5x3 panel, 10 paylines

- 5 Scatters: 5x5 panel, 40 paylines
How expanding symbols work:

- Expanding symbols pay even on non-adjacent positions and are evaluated on 10 paylines, regardless of panel size
- Wilds do not substitute for expanding symbols
