How to play Book of Books mobile slot

The Book of Books slot gives you 10 paylines and 5 reel filled with fantasy symbols such as the wild, scatter, and free spins with multiple expanding scatter pays.

If you’ve enjoyed online slots such as the Cauldron slot of the Book of Bob review, you’ll be familiar with the fun themes set by this provider, from the three musicians playing on the side to the King, wizard and knight as the highest paying symbols.

The Book of Books mobile slot is a volatile game with 10,000x your bet max wins with a superbet option that, for 1.5x extra on your bet, you increase your odds of hitting the free spins.

And the free spin is where you can all of your top wins thanks to the fact that you can get multiple expanding scatter pays and bigger multipliers on retriggers.

What is the Book of Books slot all about?

If you can, press the Golden Bet button to increase your odds of getting the free spins. Why? Because without it, you probably won’t get much more than 500x your bet.

The base game has nothing much to give but the free spins. You are waiting to get 3 scatters and at least 7 free spins where one symbol will always expand and pay as a scatter – that symbol changes from spin to spin.

But you want 4 or 5 scatters, which will expand the reels and give you 20 or 40 paylines but with the same paytable. That makes this paytable really pop.

The PowerUp make the free spins sing

Once you trigger the free spins, you just need 2 scatters for interesting things to happen. For example, you can get extra free spins or increase the overall game win multiplier.

But what makes it particularly interesting and stand out from the likes of Legacy of Dead slot or the Book of Dead game, is that you can get multiple expanding scatter pays at the same time.

The Book of Books slot machine is a fun version of the expanding scatter pays concept and one you will love if you are a fan of the genre.

Bonus Features

Wild: The W is the wild and replaces all other symbols to help create wins. It does not replace the scatter.

Scatters and Free Spins: 3 or more scatters trigger 7 free spins.

  • 3 scatters triggers a 5x3 panel with 10 paylines
  • 4 scatters triggers a 5x4 panel with 20 paylines
  • 5 scatters triggers a 5x5 panel with 40 paylines

At the beginning of the spin, one of the symbols will be chosen to act as an expanding scatter pay. The symbol will expand, cover the reel and pay like a scatter - i.e. on all paylines regardless of where they land.

The expanding scatter pay symbol can change from spin to spin.

Power Ups: landing 2 scatters in the free spins bonus will give you -

  • 1 or 2 additional free spins
  • An additional expanding symbol
  • a 1x or 2x expanding multiplier that multiplies any winnings with expanding scatter symbols. Collected expanding multipliers are added together.

Golden Bet: for an extra 1.5x your bet, you increase your odds of hitting the bonus games.

Buy Free Spins: For 100x your bet, you can buy entry into the free spins. The RTP of the Book of Books slot game goes up slightly at 96.2%.


  • Free Spins with Expanding Scatters
  • High 10,000x bet
  • High 96.01% RTP
  • Low 0.10 minimum bet


  • Golden bet needed to hit free spins

Book of Books Review Conclusion

The Book of Books slot on mobile is a nice addition to the genre - we especially like that you can get multipliers, bigger paylines, and extra expanding scatter pays.

There's something fun about the quick play, the extra features in the free spins and the ability to bet a little extra to improve your odds of winning.

We still kinda prefer playing on the Voodoo Hex slot if we choose Peter&Sons as our casino game provider for the night, but fans of the 'Book Of' series will enjoy this fun iteration.
