Full Review

The gamble feature in Book of Dead is exactly what it sounds like: a binary risk decision that sits between you and keeping your win. After any winning spin, Play'n GO's interface presents the option to gamble that win — double it or quadruple it — with the downside being that losing the gamble forfeits the original win entirely. No consolation, no partial return. I've watched players burn solid base-game hits this way because they underestimated how quickly high volatility already swings bankrolls on this game.

How exactly does the gamble feature work?

After a winning spin resolves, a prompt appears giving you the choice to accept the win or enter the gamble round. Inside the gamble round, you're typically choosing a card suit or color outcome to double or quadruple the win amount. Nail it and your win multiplies; miss it and the win disappears. There is no middle outcome. Given that Book of Dead runs 10 fixed paylines with high volatility — meaning wins are infrequent but large when they arrive — gambling away a rare meaningful hit carries real bankroll consequences. The game's maximum win potential sits at 5,000× your total bet, or up to $500,000 depending on stake size, which means base-game wins worth gambling are statistically uncommon to begin with.

Should you use the gamble feature?

That depends entirely on your session goal and remaining bankroll. If you're deep into a dry spell and a modest win has partially recovered your stake, gambling it away sets you back further against the house edge — the standard RTP is 96.21%, but as I cover in the Book of Dead RTP Compared: 96.21% Down to 84.18% breakdown, your casino may be running a lower configuration, which makes bankroll preservation more important, not less. Players grinding toward a free spins trigger are better served banking small wins. Players with a large buffer who treat the gamble as entertainment have more latitude, but should never expect it to reliably build a balance — it's a coin-flip mechanic, not a strategy.

How does the gamble feature compare to other risk mechanics in the slot?

Does the gamble feature affect free spins or bonus eligibility?

No — the gamble feature only applies to cash wins from base-game spins. It has no interaction with the free spins trigger, and winning or losing the gamble round does not influence whether the expanding symbol mechanic pays out during a bonus round. For a full breakdown of how the free spins and expanding symbol work, see the Book of Dead Slot Review: Play'n GO's 5,000x Volatility Machine.

Where can US players access this feature legally?

Real-money iGaming — including access to the gamble feature in a licensed environment — is available in New Jersey, Michigan, West Virginia, Pennsylvania, Connecticut, and Delaware. Play'n GO's January 2024 deal with BetRivers specifically covers Michigan, New Jersey, and West Virginia; it does not extend to Pennsylvania or Delaware via that operator. If you're in a state without licensed iGaming, sweepstakes casinos operating under a promotional model may offer the title, though the gamble feature's availability in that format should be confirmed directly with the platform. Before chasing any bonus attached to this game, check the Book of Dead Free Spins: Best Bonus Offers Compared page for current state-eligible offers, and review Book of Dead Free Spins No Deposit: What US Players Get if you're specifically hunting no-deposit options — terms vary significantly by state and operator.
