To trigger the Book of Dead bonus, land 3 or more Book of Dead scatter symbols anywhere on the reels during a base game spin. This awards 10 free spins with an expanding special symbol. Released in 2016 with a 96.21% RTP, the feature can be retriggered during free spins.
How Do You Trigger the Book of Dead Bonus?
The Book of Dead bonus activates when you land 3 or more scatter symbols (depicted as the golden book) across any position on the 5-reel grid. Unlike payline-based symbols, scatters don't need to align left-to-right-they simply need to appear anywhere on reels 1 through 5 during a single spin. Landing exactly 3 scatters triggers 10 free spins, whilst 4 scatters award 15 free spins, and 5 scatters grant 20 free spins according to the Play'n GO paytable. The bonus activates immediately once the reels stop spinning, and you cannot re-spin or cancel the feature. This straightforward trigger mechanic makes Book of Dead a popular choice for players learning how high-volatility slots work.
What Happens During the Expanding Special Symbol Feature?
When the free spins round begins, Play'n GO randomly selects one base game symbol to become the expanding special symbol for that entire bonus round. If this symbol lands on reel 3 during any free spin, it expands to cover the entire reel and counts as a full reel of matching symbols, dramatically increasing win frequency. The expanding symbol remains active throughout all retriggered free spins, compounding the potential for larger multipliers. This mechanic can transform a single bonus round into multiple consecutive wins, especially when the expanding symbol aligns with high-value icons. The unpredictability of which symbol expands adds strategic interest to the bonus experience.
Can You Retrigger Free Spins During the Bonus Round?
Yes, retriggering the Book of Dead free spins is one of the slot's defining features. Landing 3 or more additional scatter symbols during an active free spins round awards 10 extra spins, which stack on top of your remaining balance. Many players report retriggering occurring multiple times within a single bonus session, especially given the slot's high volatility. There is no limit to how many times you can retrigger, so theoretically, a single bonus activation can extend to hundreds of spins if fortune favours you. This retrigger potential is why Book of Dead appeals to high-variance slot enthusiasts seeking longer play sessions.
Where Can You Play Book of Dead and Trigger the Bonus?
Book of Dead is widely available at UK-licensed casinos. For the full spec sheet, demo link, and certified RTP confirmation, see our main Book Of Dead page. Popular operators hosting the slot include Playojo, Lord Ping, and Slots Temple, all regulated by the UKGC. Before you play, verify the casino holds a valid operating licence and displays BeGambleAware resources prominently. Stakes range from £0.10 to £100 per spin, so you can adjust your bet size to suit your bankroll. As of 2026, players aged 18-24 face a £2 maximum stake per spin, whilst those 25+ can stake up to £5 under recent UKGC reforms, so confirm your eligibility before depositing.
How Does Bonus Frequency Affect Your Trigger Chances?
Book of Dead is a high-volatility slot, meaning scatter triggers occur less frequently than in low-volatility games but award larger multiplier payouts when they do land. Across extended play sessions, the 96.21% RTP reflects a long-term return, not a guarantee of near-term bonus frequency. Stake size does not alter the mathematical probability of landing 3+ scatters-the paytable odds remain identical whether you bet £0.10 or £100. Understanding this distinction is crucial for responsible gambling: players sometimes mistakenly believe larger bets increase bonus hit rates, leading to overstaking. The UKGC 2026 regulations enforce strict stake caps specifically to protect players from pursuing losses through escalating bets.

How Does Book of Dead Compare to Similar Egyptian-Themed Slots?
Book of Dead pioneered the rich-Egyptian theme in 2016 and influenced many successors. For comparison, Legacy of Dead uses a similar scatter mechanic but features 10 paylines versus Book of Dead's 10, whilst Cat Wilde and the Doom of Dead adds cascading reels for enhanced win potential. To understand how these bonus mechanisms work across the Egyptian category, explore our How Megaways Slots Work guide. The expanding symbol feature sets Book of Dead apart from classic scatter-only slots, making it a reference point for evaluating bonus game design. If you enjoy this trigger style, you'll likely appreciate other Play'n GO titles within the Play'n GO portfolio.
Key Takeaways for Triggering the Bonus Responsibly
Trigger the Book of Dead bonus by landing 3 or more scatter symbols on any reels; this awards 10 free spins with an expanding special symbol active throughout the round. Retriggering is possible and common in high-volatility play sessions. Your stake size does not influence trigger probability-the paytable odds are fixed. Under 2026 UKGC rules, verify your age-based stake cap (£2 for 18-24 years, £5 for 25+) before wagering. Play only at licensed operators, and use BeGambleAware resources if you feel gambling is becoming unmanageable.
