Slot Summary

In 2024, ESA Gaming sent the book-slot format to sea with Book of Rrrum. A captain's secret rum recipe gives the pirate setting a specific purpose, while the familiar symbol-selection idea meets cascading wins and rising multipliers. The result connects a recognizable book-game structure with a bonus that can develop through repeated wins.

How It Plays

The main game pays on 10 lines. Its book feature selects a special symbol, giving that chosen symbol a role beyond its ordinary paytable value when the feature operates.

The optional BOOST function can randomly activate the book feature during the main game. This provides access to the selected-symbol behavior before a conventional free-spin trigger lands.

Theme & Atmosphere

The book contains the captain's rum recipe, tying its role to the pirate story. That gives the central object a purpose within the setting beyond marking a bonus trigger.

ESA Gaming describes the pirate treatment as a humorous narrative. Its seafaring adventure uses the captain and his drink as the central story, keeping the tone playful within the pirate setting.

Bonus & Free Spins

Landing at least 3 scatters opens a free-spin mode. Normal and Super Free Spins combine cascades with increasing multipliers that persist during the bonus, with the Super version offering enhanced multiplier values.

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 (96.00%), with wins capped at its top multiplier (7,000×).

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.
