The Book of Darkness slots game plays out in a room filled with columns and strange carvings on the walls. This magical realm sits behind the 5x3 reel set, where you see playing card symbols, potions, crystals, and a ring. The top symbols are the arrow-firing Huntress, powerful Dark Wizard, and the book itself.
The images create a fantasy style across PCs, Android, iOS, and Windows-powered mobile devices, and while not up to the standards of their 3D-effect games, Betsoft has certainly done a good job bringing a mythical world to the best online casinos.
The features include the book acting as any other symbol if it can complete a combination across any of the 10 paylines, and a thrilling Clash for Power free spins bonus round. The Huntress and Dark Wizard do battle and can take you through to a further bonus feature with expanding symbols or win multipliers.
A wager range of 0.10 to 10.00 makes this a game far more suited to lower-stakes players than high rollers, and the relatively small maximum prize of 1056x the stake means that no one is going to win a fortune playing the Book of Darkness slot with real money or a bonus.
However, it’s easy to set up and suitable for relatively inexperienced players, as well as anyone who enjoys the theme of wizards and fantasy worlds. Select your stakes from the scrollbar below the reels, and if you want to play without having to click the Spin button each time, press the circular arrow tab and activate an Autoplay feature.
The ‘I’ tab on the left side of the controls opens the paytable. You’ll see a full breakdown of how much you win from each symbol when it crosses a line from the left, plus details on the bonus features, such as the special Clash for Power free games.
The wild book symbol is the only special feature in the base games, but there are several free spins rounds. Any 3, 4, or 5 book symbols pay 2x, 20x, or 200x your wager respectively. You then claim 10, 15, or 20 free spins with a random symbol expanding across reels to help create wins throughout.
If the Huntress, book, and Dark Wizard land on adjacent reels on the same row, it launches the Clash for Power free games. Pick a character symbol before the games begin, and both expand to fill reels, while at the same time filling a meter on each appearance. There’s no limit to how long this takes, but if your chosen character fills their meter first, you move on to the Shadowform free games round. Should your character lose the Clash for Power, you return to the base games.
In the Shadowform feature, you get 10 free games. If you chose the Huntress, all wins from high value symbols get multiplied by 5x, and if your pick was the Dark Wizard, 5 symbols will expand across any reels they land on.
The most that you can win from the Book of Darkness online slot is 1056x your wager, which is quite a low multiplier, and with maximum stakes of just 10.00 per spin, that equals a disappointing 10,560.00.
It’s a medium variance game, and taken as a long-term average figure, for every 100.00 staked, it pays back 96.48 in prizes.
Apart from the relatively small maximum win and wager levels, the Book of Darkness slot is a game that fans of the magical theme are sure to enjoy. The multi-stage bonus round is the highlight, with the Clash for Power free spins leading on to the Shadowform games if you choose the winning character symbol.
If you are happy to stake 10.00 or less per spin, then you will enjoy this game. Find it at our top-ranked online casinos, where a generous bonus package is waiting to be claimed.
