Book of Tombs (Booming Games) – Review & Demo Play

Book of Tombs Slot Overview

I’ve spun Book of Tombs from Booming Games and it sticks to the famous "Book of" mechanic. The layout is 5 reels by 3 rows with 10 paylines, in a clear Ancient Egypt setup. The Book symbol acts as both Wild and Scatter, so it helps complete lines and triggers the feature. Land 3 to 5 Book symbols to enter Free Spins with a special Expanding Symbol. Retriggers are on, and the round can add more expanding picks as you go.

If you like a bit of risk, the Gamble feature lets you try to double or quadruple a win by guessing a card colour or suit. The mechanic is simple to follow and the pace feels right for 10-line play. I’ve had streaky spells in the base game, but the feature can swing the session. The mix of Wild Scatter utility and expanding outcomes gives proper win spikes when the selected symbol hits across the grid.

Base Game in Book of Tombs

In the base game, the Book is the Wild Scatter, so it substitutes and also triggers the bonus. Higher-value picture symbols include the explorer, pharaohs and urns, with 10-A royals on the low side. Lines pay left to right across the 10 paylines. During Free Spins, one symbol is selected to become an Expanding Symbol. When it can form a win, it expands over its reels and pays on any position on active lines, which lifts the hit potential.

Retriggers can stack. I’ve seen the round add more Expanding Symbols, up to nine across the session, which changes the feel fast. Low symbols filling the grid can crank volume on medium wins, while premiums landing in view on multiple reels are where the bigger totals sit. The mechanic sticks to the classic "Book of" pattern, so symbol behaviour stays clear, and the Book icon keeps its double duty throughout, which helps the flow between base spins and features.

Book of Tombs Maximum Wins, RTP, & Volatility

I see a below-average RTP of 95.42% paired with high volatility, so sessions can whipsaw before the feature lands. Hit frequency sits at 34.17%, with Free Spins roughly 1 in 153 by the sheet. The max win is 5,504x stake, which reaches £412,800 at the £75 cap, while stakes start from £0.10. That profile suits players who enjoy long-game potential rather than steady drips. Bankroll management matters, as dry spells appear between those stronger expanding hits.

Our Book of Tombs Slot Rating

I rate Book of Tombs as a straight "Book of" outing that doesn’t stray far from the tried and tested formula. The look is clean and the feature carries the weight, with retriggers turning decent runs into standout sessions. Base play can throw chunky line hits, though I bank on the Free Spins to do the heavy lifting. I come back when I fancy classic expanding action with the Book pulling double duty and a 5,504x ceiling in reach.
