Paris Gamblers review · Play'n GO · 2016
Book of Dead keeps its Egyptian adventure on a simple 5x3 layout. The title has five documented RTP configurations, while Play'n GO's rules file places it at 10 on the provider's VERY HIGH volatility scale. Most of the structure is easy to follow; the important checks are the active RTP, line count, and currency settings.

Best for
a direct, very-high-volatility expanding-symbol feature
A lean, very-high-volatility feature chase for readers who will verify the deployed RTP before comparing it with another slot.
Book of Dead pairs a 96.21% top RTP configuration with provider-scale very high volatility, 1–10 paylines, and retriggering expanding-symbol free spins.
These are the numbers and mechanics to compare before opening a nearby review.
Book of Dead RTP
96.21% top configuration
RTP is a long-run model for the reviewed version. Read it with volatility, max win, and feature access before comparing similar slots.

Very high (provider scale 10)
Volatility is the best quick signal for how steady or swingy the review expects the game to feel between stronger moments.

Max win is the stated ceiling or potential for the reviewed version. It does not show the chance of reaching it or replace the volatility label.

The free-spins rules decide where the slot's value sits, especially when wilds, multipliers, or retriggers carry the upside.
Compare free spinsThe game uses five reels, three rows, and one to 10 adjustable paylines. Lines activate in numerical order, wins pay left to right, and only the highest win is paid on each selected line. The Book substitutes as a wild and also works as the scatter. The rules file lists 96.21%, 94.25%, 91.25%, 87.25%, and 84.18% RTP configurations, with market and operator settings able to change what is deployed.
Three or more Books award 10 free spins. Before the sequence, one ordinary symbol is chosen at random; it can expand over all three positions on its reel when doing so produces an additional prize on an active line. Matching expanded symbols do not need to be adjacent, and another 3+ Books add 10 spins. The optional gamble round doubles a win for a correct colour or quadruples it for a correct suit, with up to five successive attempts and a 2,500-coin rules-file limit.
Book of Dead suits readers who want a traditional payline slot with one central feature rather than a chain of modifiers. The selectable lines, dual-purpose Book symbol, and ten-spin retriggers are straightforward once the active settings are known.
Skip it if a lower-volatility pace or one fixed RTP figure is essential. Check the information screen for the deployed return, currency range, active lines, and optional controls instead of assuming the 96.21% and 0.01–100 source settings apply everywhere.
The 5x3 grid and single expanding symbol stay readable on a phone. The more important mobile check is the information panel: confirm the active RTP, currency values, line count, and optional controls before making a comparison.

Push Gaming
Razor Shark is one of the sharper very-high-volatility picks in this set because it layers expanding systems and bonus upgrades without losing the core logic.

Pragmatic Play
The original Gates of Olympus combines 96.50% RTP, provider-described high volatility, 8+ pays-anywhere tumbles, and multiplier symbols worth up to 500x.

RTP mechanics guide
RTP is the theoretical long-run share returned as prizes by one game configuration. Actual RTP measures past results from a particular sample. Neither predicts the next spin; theoretical RTP does not predict a session, win frequency, or payout size.
Bonus-feature mechanics guide
A slot bonus feature is an extra rule or game state such as free spins, respins, collection, multipliers, or direct feature access. The game rules decide how it starts, changes, and ends.
Free-spins mechanics guide
Free spins are extra rounds awarded by an in-game feature. The paytable sets the trigger, starting spin count, retrigger rules, and any wild or multiplier changes.
Symbol mechanics guide
A wild usually substitutes for ordinary paying symbols. A scatter can pay outside paylines or unlock a feature. The exact paytable decides both roles, including every exception.
Provider directory
A slot provider is the studio label attached to a game. Use the directory to find reviewed titles from each provider, then compare the game-level RTP, volatility, mechanics, and configuration separately.

Play'n GO's rules file rates it 10 VERY HIGH on the provider's own scale. That label does not change with the RTP figure, so compare both fields separately.
