Book of Mystery is an Egyptian book slot from JDB Gaming, played on a 5x3 grid with 10 paylines and a book symbol that works as both wild and scatter. Three or more books award 10 free spins with a randomly chosen expanding symbol. The game has a 5,000x top payout, a 96.42% RTP and medium-high volatility.
Game mechanics
On the 5x3 grid, wins pay from left to right along 10 fixed paylines. The book does two jobs: as the wild it substitutes for every other symbol, and as the scatter it pays anywhere and triggers the bonus.
Three or more books award 10 free spins. Before the first of them, the game picks one symbol at random as the special expander; when enough copies of it land during the round, it stretches to cover full reels and pays like a scatter, ignoring normal line positions.
Features
- Book wild and scatter. The book substitutes for every other symbol and also pays as a scatter anywhere on the grid, so a single symbol handles both line wins and the bonus trigger.
- Free spins. Three or more books anywhere on the grid award 10 free spins.
- Expanding special symbol. One symbol is drawn at random as the round begins; while the free spins last it can expand over entire reels and pay across the grid rather than along paylines.
How to play the free demo
- Read each win in the Book of Mystery demo from left to right along the 10 fixed lines, remembering that a book can stand in as a wild to complete one.
- Count the books on each spin: three or more anywhere pay as scatters and start 10 free spins.
- Once free spins begin, check which symbol was drawn as the expander, then watch it stretch over full reels when it lands in numbers.
Why try the Book of Mystery demo
The free spins are the round to see, because the expanding symbol is drawn afresh each time the round starts. Trigger it a few times in the demo and the reels fill quite differently from one expander to the next.
