Book of Shadows is an exciting addition to the popular book slot series, with unique features and mechanics to set it apart from the rest. Here is a comprehensive breakdown of the features and mechanics that players can expect from the game:

- Theme: Book of Shadows takes players to a spooky graveyard with cartoon-style symbols, offering a refreshing break from the typical ancient Egyptian tomb theme.
- Reels and Paylines: The standard 5x3 reel setup with 10 paylines, but players can customize the game to a 5x4 or 5x5 setup via the Shadow Rows feature.
- Shadow Rows: Costing extra per spin, the Shadow Rows feature allows players to increase the number of paylines (from 10 to 15 or 20) and increase the RTP slightly.
- Lucky Locks: This feature allows players to lock up to 4 reels in place after every spin, and spin only the remaining unlocked reel(s).
- Gamble Feature: Players can gamble all wins, doubling or nothing by picking the correct card color, red or black. The correct guess can be made up to 5 times in a row.
- Wheel of Bonus: A feature that allows players to gamble to win the free spins bonus round. The size of the red segment increases with your bet size, and players need to land at least 3 book scatter symbols anywhere on the same spin to trigger the free spins bonus round.
- Free Spins: The number of free spins players receive depends on the number of rows they choose: 3 rows (14 free spins), 4 rows (12 free spins), or 5 rows (10 free spins).
- Golden Symbol: A special symbol chosen before the feature starts, which will expand to cover the full reel after the regular win calculation. The golden symbols do not have to be adjacent to win, and the expanded reels offer a chance to win up to 10,000x your stake.
- Retrigger: The bonus round can be retriggered by landing 3+ scatters on the reels.
- Bet Levels: Players can choose a bet level between 10p and £100 per spin, but going with more rows will increase the bet size and slightly increase the RTP.
- Paytable: Players can check out the paytable via the hamburger menu, with the highest value symbol being the book scatter wild and the goth girl.
- Fast Play and Autoplay: Players can also enjoy the fast play option via the lightning icon next to the spin button and set up the autoplay feature with between 10 and 1,000 autospins.
- Bonus Buy: The bonus buy option is available for players, with a cost of 60x, 90x, or 120x your stake for 10 free spins with 3, 4, or 5 rows, respectively.

Book of Shadows offers players a unique and thrilling gaming experience, with a high potential of 30,338x max win and a multitude of customizable options for players to explore.
