Book of Mystery is JDB Gaming's take on the classic Egyptian book slot: a 5x3 grid, 10 paylines, and a book symbol that acts as both wild and scatter. Three or more books award 10 free spins with a randomly chosen expanding symbol. Listed at 96.42% RTP with a 5,000x top win, and free to play here.
Game mechanics
Book of Mystery follows the book-slot formula closely: wins pay left to right across 10 fixed paylines on a 5x3 grid, and the book symbol does double duty as the wild (substituting for everything else) and the scatter (paying anywhere and triggering the bonus).
The main event is the free spins round. Three or more books award 10 free spins, and before they start the game picks one symbol at random to be the special expander — when enough of it lands, it stretches to cover full reels and pays like a scatter, ignoring normal line positions. The game is listed at 96.42% RTP with medium-high volatility and a 5,000x cap.
Features
- Book wild and scatter. The book substitutes for every other symbol and also pays as a scatter anywhere on the grid, so one symbol drives both line wins and the bonus trigger.
- Free spins. Landing three or more book symbols awards 10 free spins, and the round can bring the game's biggest payouts.
- Expanding special symbol. At the start of free spins one symbol is chosen at random; during the round it can expand to fill entire reels and pay across the grid rather than along paylines.
