Slot Summary

TrueLab Games entered the Book slot format with Book of Truth, retaining the familiar dual-purpose Book while adding a second, stronger Free Spins route. Three or four Book symbols select one Expanding Symbol, but five open True Free Spins, where every regular symbol can expand. That distinction gives this medium-volatility Egyptian release a clear escalation path toward its 15,000x maximum win.

How It Plays

The base game uses 10 paylines on a 5x3 layout. Its Book symbol substitutes as a Wild and also acts as the Scatter that controls bonus entry.

Ordinary spins follow traditional line evaluation, so the main decision is whether to wait for a natural Scatter trigger or use the available Bonus Buy option.

Theme & Atmosphere

Ancient Egypt, Mythology, and the Book theme meet through a text presented as both treasure map and luck amulet. The artifact carries the setting's central mystery.

The Action & Adventure tone comes from seeking hidden pharaonic wealth rather than following a named ruler. Temples and the Book frame discovery as the main narrative action.

Action & Adventure Mythology Egypt Book Ancient

Features & Win Potential

The Book serves as both Wild Symbol and Scatter Symbol. Landing the required count starts Free Spins, while the number of Books determines which feature version opens.

Expanding Symbols separate the two modes. The standard round selects one symbol, whereas the higher trigger allows every regular symbol to expand when it appears.

Bonus & Free Spins

Three or four Book Scatter Symbols award Free Spins with one randomly selected Expanding Symbol. That chosen symbol can cover its full reels during the round.

Five Book Scatters trigger True Free Spins, where all regular symbols receive Expanding Symbols behavior. A Bonus Buy provides direct access where that option is available.

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 (94.00%), with wins capped at its top multiplier (15,000×).

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.
