Slot Summary

A run of consecutive cascades can earn passage to the map bonus in Bonus Island, Inspired's pirate slot. Treasure hunting continues beyond the reel setting: the bonus asks players to uncover prizes and consider the captain's cash offers. Its island premise connects the spinning game to a separate sequence of decisions.

How It Plays

The base game uses six reels and five rows with 15,625 ways to win. Winning symbols clear through cascades, allowing replacement symbols to continue the same paid round.

Blank mystery positions need a cannonball to reveal their contents. The transformation produces paying symbols or coins; coins lead to a cash feature that awards values at the transformed positions.

Bonus & Free Spins

Four or more consecutive cascades activate the island bonus. The map contains cash and free-spin possibilities, with longer qualifying cascade sequences improving the available selection of prizes.

After rounds of map picks, the captain can offer a cash amount to accept or reject. If the outcome awards free spins, their win multiplier increases after each cascade.

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 (95.78%), with wins capped at its top multiplier (25,000×).

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.
