Book of Dead at a Glance

Book of Dead is a 5-reel, 3-row, 10-payline video slot from Play'n GO, live since 2016 and still one of the most-played titles across European casinos. The theme follows Rich Wilde — Play'n GO's recurring adventurer — through an Egyptian tomb, but the theme is almost beside the point. What matters is the math: ten paylines, a tiny symbol set, and high-value icons (the Book, Rich Wilde, the Pharaoh mask, the Ankh) sitting above the usual A–J royals. Concentrating value into so few symbols and lines is a deliberate choice — it makes the win distribution lumpy, with little happening for long stretches and the real money arriving in bursts.

The Book is the hinge the whole game turns on: it pays as a wild on the paylines and acts as the scatter that opens the free spins. Because one symbol does both jobs, it surfaces far more often than a pure scatter would, which is the only thing keeping the base game from feeling completely inert between bonuses.

The Expanding-Symbol Engine

The Book Wild / Scatter

The Book symbol substitutes for all other symbols on a payline win — it functions as a standard wild. More importantly, landing three Books anywhere on the reels (not on a payline) triggers the free spins round. This scatter-anywhere mechanic means you don't need to land Books on a specific line, which reduces some of the frustration from near-miss near-triggers that appear on strict left-to-right payline games.

Free Spins with Expanding Symbol

Before the free spins begin, the game randomly selects one symbol that will expand during the round. This symbol, whenever it appears anywhere on a reel, expands to cover the full reel height — effectively giving you three of that symbol on that reel. The payout structure of the round depends almost entirely on which symbol is chosen and how often it lands.

The Rich Wilde symbol pays best. Five Rich Wildes pay 200× stake in the base game. When Wilde is the expanding symbol in free spins and lands on multiple reels simultaneously, five-reel coverage returns the top jackpot — around 5,000× stake at max line coverage. The royals (A, K, Q, J, 10) can also be the special symbol, which is considerably less exciting. Getting A–J as your expanding symbol after three Books is one of the more deflating outcomes in casino gaming.

Re-triggers

Landing three or more Books during the free spins round re-triggers 10 additional spins. The expanding symbol carries over from the original selection — you don't get a new one. Re-triggers are relatively rare, but when they stack alongside a high-value expanding symbol, they're where the game's highest payouts come from.

RTP and the 94.25% Trap

The headline RTP is 96.21% — solidly above average for a video slot, and one of the reasons Book of Dead became a benchmark title for bonus-wagering comparisons. The catch is that the exact same game ships in a 94.25% configuration that some operators choose to run. Visually the two are indistinguishable; only the internal math differs, and almost two points of RTP is a meaningful tax over a long session. Open the game info panel or the casino's game page and confirm the displayed figure before you spin. If an operator won't publish which version it runs, treat that silence as an answer.

Variance & Bankroll

The volatility here is genuinely very high — not the "high" that turns out to be medium once you play it. Almost all of the return is locked inside the free spins, and within that, inside the single expanding symbol you happen to draw. Base-game play between triggers is a slow grind with the odd Book wild doing minor work, so plan your bankroll around the dry spells, not the highlight reel: a run of 300–500 spins before a bonus pays is an ordinary outcome, not bad luck. A practical rule of thumb is a balance of at least 200–300× your spin stake if you want a realistic shot at reaching a paying free-spins round without topping up.

Book of Dead on a Phone Screen

Play'n GO has built mobile-first since the mid-2010s, and Book of Dead shows it. The 5×3 grid sits comfortably in portrait, the Book symbol stays legible at phone size, and the expanding animation during free spins reads clearly without dragging out the round. Nothing here is reinvented for touch — it simply carries over from desktop without the cramped menus or dropped frames you still see on older ports.

Stake adjustment is a single tap, which matters more than it sounds when you are trimming bets to stretch a session. Auto-spin, where it is offered, runs reliably; if it is missing entirely, that is almost always an operator's compliance setting for your jurisdiction rather than a fault in the game.

Strengths & Weaknesses

Who It's For

Book of Dead rewards patience and a bankroll that can sit through silence. If you enjoy the tension of a single high-variance bonus round where one symbol draw decides whether you walk away up or flat, it remains one of the cleanest examples of the format ever made. If you prefer frequent small wins or feature-rich base games, the long dead stretches will wear you down — this is not a slot to play tired or under-funded.

It is also a poor fit for clearing bonuses despite contributing 100% to wagering: the variance can empty a balance before requirements are met. For that job a steadier title is safer. If you specifically like the expanding-symbol mechanic, the closest comparison is Book of Ra, the Novomatic original that Book of Dead refined; for a same-studio alternative with a slightly gentler base game, Play'n GO's own Legacy of Dead runs the same engine with more high-value symbols in the mix.
