Graphics, Sounds and Animations

The soundtrack of Book of Books uses dramatic drumbeats and string notes, bringing to mind classic fantasy film soundtracks. It’s easy to imagine the troupe of minstrels playing their instruments by a crackling fire to create the epic tune.

The reels are crafted from blocks of stone, with characters in medieval garb on either side. One plays a flute, while the others pluck at handmade string instruments. The animation style brings to mind modern children’s cartoons, giving this slot a playful feel.

Among the symbols, players will find each of the card suits carved in stone, as well as swords and axes. A variety of characters appear as well, including a knight, a king, and an eccentric wizard.

Behind the reels, a forest and a starry sky can be seen. Each tree gently sways in time with the music, adding to the magical atmosphere.

Together, the soundtrack and animation of Book of Books create a wacky fantasy world.

Wilds, Bonuses and Free Spins

This slot features 10 expanding symbols which have the special ability to cover their entire reel.

If players land 2 Scatter symbols, they are awarded ‘Power Ups’ or special features that are added to the Free Spins feature. These include: 1-2 extra free spins, an extra expanding symbol, or 1x-2x expanding multipliers.

The Wild symbol substitutes for all symbols except the Scatter symbol.

The Free Spins feature is triggered when players land at least 3 Scatter symbols. The nature of the feature depends on the number triggering Scatters as follows:

  • 3 Scatters = 5x3 reel structure + 10 win lines
  • 4 Scatters = 5x4 reel structure + 20 win lines
  • 5 Scatters = 5x5 reel structure + 40 win lines

The Free Spins feature begins with 7 free spins, with the addition of any gained earlier through Power Ups.
