Slot Summary

A Book Of game need not wait for scatters to produce an expanding-symbol event. Book of Thor can award its Thunderblast Bonus after a non-feature base spin, giving Qora Games a second route to the mechanic alongside Free Spins. The 96.05% RTP, Medium/High profile, and x2500.00 maximum win keep the familiar 5x3, 10-payline structure intact, while Thor and Viking mythology supply the setting.

How It Plays

Regular wins follow 10 fixed paylines from left to right across the 5x3 layout. The Book substitutes as a Wild and also operates as a Scatter.

A non-feature base spin can receive Thunderblast at random. The event selects a qualifying symbol and expands it across relevant reels when that expansion creates a line win.

Theme & Atmosphere

Book of Thor combines Book and Viking themes through Thor, runic details, and an ancient tome that carries both Wild and Scatter functions.

Mythology and Thunderstorm cues support the randomly awarded Thunderblast event, giving the base-game interruption a thematic reason rather than presenting it as an abstract modifier.

Mythology Book Guns Viking Thunderstorm

Features & Win Potential

The Book acts as both Wild Symbol and Scatter Symbol. As a Wild, it substitutes for regular symbols; as a Scatter, it opens Free Spins.

Expanding Symbols are selected from the regular symbols visible after a Free Spin. A selected symbol expands only when doing so creates a qualifying line win.

Free Spins Scatter Symbol Wild Symbol Medium/High Book Of...Bonus Buy Expanding Symbols Bonus Bet

Bonus & Free Spins

Three, four, or five Scatter Symbols award 8, 12, or 25 Free Spins. Additional Scatters during the round can retrigger the corresponding number of spins.

The Bonus Buy provides direct entry to Free Spins. Purchased and naturally triggered rounds use the same expanding-symbol selection and retrigger rules.

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-High). The model is calibrated so the average return equals this slot's published RTP (96.05%), with wins capped at its top multiplier (2,500×).

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.
