Slot Summary

Released in 2025, Book of Odin applies the familiar Book format to a Norse Mythology setting while giving the player control over the active paylines. TrueLab Games lets the line count range up to 10, so stake structure and hit behavior can change before the bonus begins. The Wild Symbol then opens Free Spins, where a selected regular symbol can cover full reels and further Wild Symbols may award Additional Free Spins.

How It Plays

The 3x5 grid supports a selectable line count from 1 to 10. Changing the active lines alters the bet structure, hit rate, and payout calculation.

The Wild Symbol substitutes for ordinary symbols and also acts as the trigger. Once enough appear, play shifts into a round where one selected symbol receives expanded coverage.

Theme & Atmosphere

Book, Fantasy, and Mythology meet through Odin, the Norse Allfather who guards the title's central object and presides over the reel set.

The Norse setting gives the selected-symbol rule a divination theme: the chosen icon becomes the recurring focus once the Book opens the bonus round.

Fantasy Mythology Book

Features & Win Potential

The Wild Symbol performs both substitution and trigger duties. Landing enough copies activates Free Spins, while further Wild Symbols can extend the feature.

Additional Free Spins preserve the selected-symbol opportunity for longer. The feature can therefore continue beyond its initial award when another qualifying trigger occurs.

Free Spins Wild Symbol Additional Free Spins

Bonus & Free Spins

Free Spins start with 10 spins after 3 Wild Symbols land. Before the round proceeds, a regular symbol is selected for expanded reel coverage.

Further Wild Symbols can award Additional Free Spins. The selected regular symbol remains active through the extended sequence, keeping the same payout focus after a retrigger.

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 (96.16%), with wins capped at its top multiplier (10,000×).

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.
