Book of Books
Book of Books Free Slot Demo review
Book of Books is a slot built on the idea that the Peregrine Order, hidden beneath a bard’s clothing, guards the Book of Books, the source of all power and wealth. Developed by Peter & Sons and released through Yggdrasil’s YGG Masters, it launched on March 16, 2023. You can play it right away with the free demo, no sign-up needed.
What kind of game is Book of Books?
A high-volatility video slot built around the book of books, the father of all books and the greatest secret known to humankind. The unique setup has the Peregrine Knights guarding this book while hidden beneath the clothes of musicians and minstrels. Expanding symbols, a collection feature, and free spins all work together, so it is well worth trying if you like book-style Yggdrasil slots.
How does the collection feature strengthen free spins?
Book of Books has a collection feature that strengthens the free spins game. What you gather in the base game turns into power-ups when you enter free spins, so you keep checking your collection progress even on regular spins. The most anticipated moment is entering free spins with a lot collected. Try comparing how free spins change at each collection stage in the demo.
How many expanding symbols can there be in free spins?
In the free spins game, up to 10 expanding symbols can be assigned. The screen also grows to a 5×5 panel with up to 40 paylines, and power-ups and retriggers are added on top. The more expanding symbols there are and the larger the screen gets, the greater the chance of a big win at once. If a retrigger extends the free spins, the expanding symbols become even more powerful, so watch it through to the end.
Why is the base game RTP listed separately?
The overall is 96.1%, and the base game (BG) RTP is listed as 54.8%. That means the rest of the return comes from features like free spins, so this game depends quite heavily on bonuses. Since bonus buy is supported, open free spins right away in the demo to get a feel for that share. It is better to look at the feature rounds too rather than judging by the base game alone.
What should I check first in the demo?
The key numbers are 96.10% RTP, high volatility, and a max win of 10,000x. The hit frequency is about 33.26%, which is fairly frequent for a high-volatility game. In the demo, first check how quickly the collection feature fills up and how often the panel grows to 5×5 in free spins. Bets range from €0.1 to €50.
