Book of Immortals RTP and volatility
Book of Immortals has a listed RTP of 96.31%, placing it in the 96%–96.99% RTP Slots group in this database. Its volatility is classified as high. Volatility describes how unevenly wins may be distributed and is separate from the theoretical return percentage. The RTP figure is theoretical over long-term play and should not be read as a short-term payout forecast.
The RTP value shown here belongs to the configuration in the current dataset. The same title can be supplied in more than one RTP configuration, so the in-game information screen remains the final reference for a specific casino version.
Maximum win and betting range
The largest recorded win for Book of Immortals is 1,638x the stake, which places it in the 1,000x–4,999x Max Win Slots category. The listed betting range is 0.2 to 20.
A maximum-win multiplier is a recorded cap or advertised upper limit, not an expected result. Betting limits can also vary by operator, currency and game configuration, so they are best used here as comparison data.
Grid, paylines and hit frequency
The structured record for Book of Immortals includes a 5x3 grid. A payline or ways-to-win value is not present in the current record, so no number is inferred from the grid alone.
Bonus and feature data
For Book of Immortals, bonus buy is listed as not available and the feature list includes Free Spins, Expanding Symbol, and Wilds.
Feature flags on Slot Data Hub reflect the imported catalog record. They describe listed availability only and are not used to invent a bonus sequence, free-spin rules or jackpot mechanics when those details are absent.
