RTP and feature availability can vary

RTP versions and “Feature Buy” availability may differ by casino configuration and local rules. If you see different numbers in a lobby, the in-game paytable is the final reference.

The one symbol that drives the whole slot

The BOOK OF BLOODLINES symbol is the main engine here: it works as both a Wild and a Scatter. In the base game it can help complete paylines, and it’s also the trigger for Free Spins.

How the base game plays

  1. Pick your stake (this title runs from micro bets up to mid-high stakes).
  2. Wins pay on 10 fixed paylines.
  3. The Book symbol can substitute to create wins and can also appear as the Free Spins trigger.

Free Spins: where the big swings live

Land 3+ Book scatters to start Free Spins (the feature is designed as the main “spike” of the session). During Free Spins, an expanding premium symbol is selected for the bonus, which can turn a quiet spin into a full-screen hit.

  • 3+ scatters start the bonus
  • 10 Free Spins as the standard entry
  • Expanding premium symbol selected for the feature
  • High volatility means outcomes can be streaky
High volatility bankroll note

Expect longer dry spells in exchange for bigger “pop” potential in Free Spins. If you’re testing the game, start low and keep session limits strict.

Feature buys (if your casino enables them)

Some versions include two Feature Buys. One is a “Book Boost” that increases the chance of landing the Book symbol (listed as 1.4× in provider materials). The other is a direct Free Spins buy that jumps you into a 10-spin bonus.

  • Book Boost: higher Book trigger frequency for faster variance
  • Free Spins Buy: instant access to the bonus feature
  • Reality check: Feature buys don’t remove risk — they concentrate it

Who will enjoy Book of Bloodlines Dice

  • You like classic “Book” structure but want a darker, horror-leaning skin.
  • You’re comfortable with high volatility and bonus-dependent payouts.
  • You prefer a simple 5×3 + paylines setup over modern mega-ways layouts.
