Slot Summary

Players drawn to extreme grid expansion get the clearest statement of Boom Pirates when its win evaluation opens as far as 10,077,696 ways. Foxium starts with a smaller field, then lets the Boom feature add reel space only when that change can improve a payout. High volatility, a 96.19% RTP, and an x3800.00 ceiling make the expanding format more important than the familiar pirate treasure hunt.

How It Plays

Each base spin can call the expanding-reel event, but the larger field is evaluated only when opening additional positions can improve the result already present.

The maximum expansion reaches a 6x9 evaluation with 10,077,696 possible ways. This turns one qualifying spin into a much broader symbol-matching problem.

Theme & Atmosphere

Pirate, Sea, and Treasure themes give the expanding grid a raiding-party premise, with the sudden opening of new positions resembling a larger target coming into range.

Action & Adventure and Guns imagery supply the aggressive tone, while the underlying feature remains readable as a direct change in reel dimensions and winning ways.

Action & Adventure Sea Treasure Pirate Guns

Features & Win Potential

Expanding Reels can increase both the width and height used for win evaluation. The feature is skipped when the larger field cannot improve the existing payout.

Wild Symbol appearances support ordinary combinations, while Scatter Symbol results control entry to Free Spins. High volatility makes those feature transitions relatively consequential.

High volatility Free Spins Scatter Symbol Wild Symbol Medium/High 5 Reels Expanding Reels Bonus Buy 96% RTP

Bonus & Free Spins

Three Scatter Symbols award 10 Free Spins on the expanded 6x9 field. Landing another 3 Scatter Symbols during the round adds 5 Free Spins.

Bonus Buy provides direct access to the same Free Spins round for 100x the stake, bypassing the normal Scatter Symbol trigger where purchases are permitted.

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 (High). The model is calibrated so the average return equals this slot's published RTP (96.19%), with wins capped at its top multiplier (3,800×).

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.
