Book of Books Slot Review

Book of Books Slot Overview

When I first loaded Book of Books, it felt like stepping into a small medieval clearing rather than another Egypt clone. The reels sit between crooked trees, with a ragtag trio of musicians banging out folk tunes beside the grid. It looks and sounds exactly like classic Peter & Sons work, quirky and a bit offbeat, which suits a 5x3, 10‑line book slot that happily ignores the usual desert clichés.

Under the cartoon surface, Book of Books plays very differently from a standard book game. Base play is all about collecting Power Ups from near‑miss scatters, then carrying those into free spins. The grid can expand to 5x4 and 5x5 during the bonus, and you get fresh expanding symbols chosen on every spin. As someone who has hammered plenty of book slots, this one feels far more involved from spin one.

Book of Books Slot Information

Book of Books runs on a straightforward 5‑reel engine but hides quite a bit of nuance. You play with 10 fixed paylines in the base game, winning from left to right with at least three low symbols or two premiums. Stakes range from 10p up to 50 quid per spin, and the game behaves smoothly on mobile and desktop, so I have no issue grinding it on a phone during longer sessions.

The loose story has you joining a secret order guarding the so‑called book of books, with the trio of robed musicians acting as your hosts. I like how the art leans into square, chunky shapes and muted colours, keeping the focus on the reels while the band quietly noodles away in the background. It all feels familiar if you know this studio, yet distinct enough from the sea of generic book titles.

Symbols & Paytable Hierarchy in Book of Books

The symbol ladder in Book of Books sticks to classic book‑slot logic but with a medieval twist. At the bottom you have stone card suits – clubs, diamonds, spades and hearts – plus an axe, giving frequent small hits that help smooth out the ride. Above them sit hammer and sword icons and then three character symbols, with the crowned king sitting at the top as the strongest regular pay symbol.

For five of a kind, low symbols pay around five to ten times your bet, while the tools and characters climb from 10x up to roughly 150x on a full line of kings. The golden W wild carries the same value as that king and substitutes for standard symbols. The ornate book acts purely as scatter, separate from the wild, so it triggers features and Power Ups without cluttering the normal win calculations.

Book of Books Slot Features

Before you spin, you can toggle Golden Bet, which bumps your stake by half and, in my experience, lands scatter teases far more often. Any spin with exactly two book scatters awards a Power Up that remains banked until free spins. Those Power Ups come in three flavours: extra free spins, extra expanding symbols, or an expanding multiplier that sits above the reels ready to multiply wins from those expanded symbols.

Hitting three, four, or five scatters in a base‑game spin launches free spins on a 5x3, 5x4, or 5x5 grid with 10, 20, or 40 paylines. You start with seven free spins plus whatever extras you have stored. The clever twist is that expanding symbols are not fixed. On every bonus spin, the game randomly selects which symbols can expand, then pays regular line wins before expanding those icons and paying scatter‑style across ten lines.

During free spins, landing two to five scatters adds more spins and another random Power Up, and higher retriggers also upgrade the grid size for the rest of the round. On paper the Bonus Buy menu looks tasty, letting you pay 120x, 250x, or 500x your bet for guaranteed 3, 4, or 5‑scatter starts. Playing from the UK, that purchase option is disabled, so I had to earn every feature the hard way.

Mathematical & Payout Model in Book of Books

As a grinder, I always check the numbers, and Book of Books sits in that familiar high‑risk space. The default RTP is 96.1% with alternative setups around, and a hit frequency just above one in three spins means the balance does not drain as fast as some high‑variance titles. The headline figure is the 10,000x maximum win, helped by those expanding multipliers stacked on several expanding symbols when the bonus really lines up.

Book of Books: Slot Verdict

For me, Book of Books nails that sweet spot between classic book gameplay and something more involved. The Power Up system flips the usual mindset, as part of you wants to stall the trigger until you have better starting values, which can be thrilling and frustrating in equal measure. If you enjoy high‑volatility grinds and like your fantasy slots with character, this is one book I am quite happy to keep opening.
