Slot Summary

Novomatic places Book of Flames Extra in the studio's established book-slot line, then gives the format a second feature route through Hold and Win. The July 10, 2026 release combines Free Spins, Expanding Symbols, symbol collection, and fixed jackpots on a 5x3 layout. Its identity therefore comes from feature overlap: the familiar book bonus remains, but locked symbols and Respins can redirect the session toward jackpot play.

How It Plays

The five-reel base game feeds two distinct destinations. Scatter Symbols lead toward Free Spins, while qualifying bonus activity can switch play into Hold and Win Respins.

Regular spins also carry Wild Symbols, Multipliers, and an Additive symbol mechanic. These support the route toward a feature without replacing the standard reel cycle.

Features & Win Potential

Expanding Symbols define the book-style side of the game, while Symbols collection adds an energy-like accumulation target. Additional Free Spins can extend the round once active.

Hold and Win uses Respins, Sticky Symbols, and Fixed Jackpots as its contrasting route. The feature emphasis moves from line expansion to retaining useful positions.

Bonus & Free Spins

The Free Spins Bonus Game uses Expanding Symbols and permits Additional Free Spins, preserving the recognizable selected-symbol behavior associated with the book format.

The Hold and Win branch supplies another bonus structure through locked positions and Respins. Fixed Jackpots give that route a distinct objective from the Free Spins round.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (7,500×).

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.
