Book of Monsters RTP and volatility
Book of Monsters has a listed RTP of 96.5%, placing it in the 96%–96.99% RTP Slots group in this database. Its volatility is classified as very high. Volatility describes how unevenly wins may be distributed and is separate from the theoretical return percentage. RTP is useful for comparing listed configurations, but individual sessions can differ substantially from the theoretical percentage.
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 Monsters is 5,000x the stake, which places it in the 5,000x–9,999x Max Win Slots category. The listed betting range is 0.2 to 240.
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 Monsters includes a 7-7 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 Monsters, bonus buy is listed as available and the feature list includes Bonus Games, Cluster Pays, Free Spins, Hyperplay, and Progressive Free Spins.
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.
Pragmatic Play slot context

In the current normalized provider catalog, Pragmatic Play has 821 catalogued games, 96.37% average listed RTP across records with RTP data, and a newest dated release of Aug 13, 2026.

How to use this slot data
The page is generated from structured slot records and refreshes with the catalog. Values can differ between operators, jurisdictions or game versions. When a field is unavailable, Slot Data Hub prefers to omit it instead of substituting an estimate.
