The basics
Book of Dead was released by Play'n GO in 2016. It has 5 reels, 3 rows and 10 paylines. The Book symbol is both the wild and the scatter, and Rich Wilde himself is the highest-paying symbol.
Free spins with an expanding symbol
- 3 or more Book symbols award 10 free spins.
- Before the round starts, one symbol is chosen at random as the special expanding symbol.
- Whenever that symbol lands, it expands to fill its whole reel and pays on all lines — even on reels that are not next to each other.
- Free spins can be retriggered with 3 more Books.
Gamble feature, RTP and volatility
After a base-game win you can gamble it: guess the colour of a card to double it or the suit to quadruple it. It is an all-or-nothing risk and does not improve your odds.
The highest RTP version is 96.21%, but casinos can run lower ones. Volatility is high and the maximum win is 5,000x your stake.
The gamble feature in numbers
Guessing a card's colour is a 50/50 bet that doubles the win; guessing the suit is a 1-in-4 bet that quadruples it. Both are even-money in expectation, so the feature never improves your return — it only makes it all-or-nothing.
The odds of a gamble streak fall fast. Doubling a win of 10 five times in a row would turn it into 320, but the chance of guessing five colours correctly is 1 in 32, about 3.1%. In the other 31 cases out of 32 the original 10 is gone.

Questions
Which expanding symbol is best?
Higher-paying symbols like Rich Wilde pay the most when they expand, but the symbol is chosen at random — you can't pick it.
Should I use the gamble feature?
It is optional and pure chance. It makes results swingier without improving your long-term return.
How many lines does Book of Dead have?
10 paylines. You can play fewer, but expanding symbols only pay on active lines.
Is the gamble feature rigged?
It is designed as a straight guess. It is not rigged against you, but it cannot be beaten either: on average you get back what you risk.
