Book of Inferno’s Exciting New Features

emucasino-book-of-inferno-logoAnna the Explorer has hunted for ancient relics in Egypt – twice, even -, encountered rage-filled dinosaurs and now faces her greatest challenge yet: battling demons from the pits of Hell intent on world domination.

In Book of Inferno, Quickspin has brought back its adventure-seeking heroine, given her the new title of demon huntress and armed her with plenty of new burning hot features fresh from the darkest depths of the abyss.

emucasino-book-of-inferno-marked-symbolsLike the game’s demon-hunting protagonist, players should keep an eye out for any Marked symbols that may cross their path.

During the base game, a paying symbol can become ‘Marked’ at random and consequently gain a bright fiery glow. Should this happen, the symbol will be displayed in the bar above the reels. If enough Marked symbols land, they will expand to cover the entirety of the reel they are on and trigger the Pay Anywhere feature which awards a full payline win regardless of the symbols’ positions.

Additionally, a Marked symbol that lands alongside a Book of Inferno symbol will be upgraded by one tier to a Marked symbol with a higher value, potentially creating more Marked symbols that will expand and generate more wins. If the Marked symbol in question is already of the highest possible value, the upgrade will be given to the lowest value paying symbol and turn it into the highest value Marked symbol.

emucasino-book-of-inferno-wild-scatter-symbolOn the subject of the eponymous Book of Inferno, it functions as not only a paying Wild symbol but also a Scatter symbol that can trigger the game’s Free Spins bonus round. Each of these rounds begin with a random symbol being selected to become its Marked version.

The number of Book of Inferno symbols that land determines the number of free spins and the bet multiplier that are awarded as listed below:

  • 3 Book of Inferno symbols: 10 free spins and 2x win multiplier
  • 4 Book of Inferno symbols: 15 free spins and 20x win multiplier
  • 5 Book of Inferno symbols: 20 free spins and 200x win multiplier

Book of Inferno symbols award the same amount of extra free spins if re-triggered during the Free Spins bonus round.

Another way that the eponymous item appears in the base game albeit in a much flashier and more exciting way is a randomly occurring feature. By chance during any normal spin, a pentagram may appear onscreen. Upon the Book of Inferno’s emergence from it, a random paying symbol will be Marked for that spin and be displayed in the bar above the reels.

book-of-inferno-buy-bonus-featureShould the option be available to them, players keen to jump straight into the fiendish Free Spins bonus round can choose to activate it instantly with the game’s Buy Bonus feature.

Upon activating it at the cost of 125x their currently selected bet value, a minimum of three Book of Inferno symbols will land on the reels and trigger the Free Spins bonus round.
