Slot Summary

Winning combinations break apart before a paid round is finished in Book of Darius, giving its book-slot format an additional source of suspense. Tom Horn Gaming sets the search for riches in ancient Persia, with King Darius as its reference point. Shatter sequences support that treasure hunt alongside the expanding-symbol bonus.

How It Plays

Any winning combination activates Shatter mode. The winning symbols disappear and replacements enter their positions, allowing the same paid spin to produce another combination without a fresh wager.

The sequence has a defined limit: the multiplier increases with successive Shatter rounds up to 4x. Play stops cascading when that limit is reached or no further winning combination appears.

Bonus & Free Spins

Accumulating 3 Books during Shatter mode triggers 10 free spins. A special symbol is selected for the round and expands across its reel when it forms a qualifying win, without requiring adjacent reels.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (95.05%), with wins capped at its top multiplier (500×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
