Book of Dead at LolaJack Casino

At a glance

The RTP and volatility shown are the provider's usual published defaults.

How the bonus feature works

Three scatters award ten free spins, with one randomly picked symbol that expands.

Maximum win, as published

The provider lists this game's maximum win potential at 5,000× your stake. That number is the mathematical ceiling of the game's design — the biggest theoretical multiplier, reachable only in an extremely rare, high-variance result — not what a normal session looks like. Most sessions finish nowhere near it, and no guide, this one included, can predict or affect the result of a certified random-number-generator game.

Origins of the theme

Book of Dead ranks among Play'n GO's most recognizable games. It arrived as part of a larger wave of Egyptian-adventure slots that borrowed from earlier games in the genre, yet it brought its own symbol-expansion mechanic, which other studios later echoed in similar releases. The explorer-and-tomb look is simply a theme wrapped around a fairly simple, classic layout of 5 reels, 3 rows and 10 paylines.

A closer look at the mechanics

Hit three or more scatters (the Book symbol itself) anywhere on the reels and you get ten free spins. As the round begins, one regular symbol is picked at random to act as the expanding symbol for all ten spins. Each time it lands on a reel, it grows to cover that whole reel, which can lead to much bigger wins than the base game usually delivers — especially when the chosen symbol is one of the high-paying characters instead of a low-value card symbol.

What RTP and volatility mean for this game

The certified 96.21% RTP combines what the base game and the free-spins round each pay back, weighted by how often each one happens. Because the expanding-symbol free spins produce most of the bigger wins and don't trigger on every spin, much of the stated RTP is paid out over a long run of base-game spins broken up by the occasional larger free-spins result.

How it stacks up against other games in this guide

Gonzo's Quest, which this guide also covers, uses a similarly classic 5-reel layout, but the two chase big wins in different ways: Book of Dead leans on an expanding symbol that only shows up in free spins, while Gonzo's Quest grows its biggest payouts with a multiplier that climbs across back-to-back avalanche wins in the base game. They are two distinct design approaches to landing a large result from reels that look fairly traditional.

Strategy and bankroll tips

The expanding symbol for each free-spins round is chosen at random, and nothing you do can influence which one you get. Bankroll planning is better aimed at keeping enough spins in reserve to reach the scatter-triggered bonus at least once per session, because almost all of the game's bigger win potential sits in that round rather than in the base game.

Playing on your phone

With a fairly simple 5x3 layout and moderate graphics, Book of Dead is one of the lighter games in this guide, so it tends to run smoothly even on older or entry-level phones, without the heavier load that some newer cascading-grid slots demand.

About the studio

Play'n GO, a studio founded in Sweden, built much of its early name on games like Book of Dead, which became one of its flagship releases and is still among its most widely carried titles at online casinos years after launch. The studio has kept releasing games in a similar adventure-and-exploration style, but Book of Dead's pairing of a simple reel set with an expanding free-spins symbol has held up well enough that newer titles haven't fully pushed it out of most casino lobbies.

Things to know before you play

Almost all of Book of Dead's bigger win potential lives in the scatter-triggered free spins, not the base game. If the game's reputation for big hits is what draws you in, keep in mind that base-game spins mostly serve as the road to that round; they are rarely where the largest results happen.

With just 10 standard paylines, the paytable takes only a moment to read, even if you're fairly new to slots — there are no cluster sizes or ways-to-win math to learn, only ordinary left-to-right payline matches.

RNG testing and fairness certification

Play'n GO games, Book of Dead among them, are certified for RNG fairness and payout accuracy by accredited independent test labs, a requirement of the studio's own licenses in the jurisdictions where it operates. That certification belongs to the game itself, not to whichever casino happens to offer it. Also keep in mind that the round always awards ten free spins, no matter how many scatters beyond the required three land on the trigger — unlike some other studios' slots, where extra scatters add more free spins.
