How the Game Plays

Bonus Island by Inspired Gaming is a feature-packed pirate adventure set on a sun-drenched tropical shore. Abandoning traditional paylines, the game uses a massive 15,625 ways-to-win system across a 6x5 grid. Winning combinations are formed by landing matching symbols on adjacent reels starting from the leftmost side. The aesthetic is high-energy and colorful, featuring symbols such as cutlasses, anchors, maps, and muskets. Every win triggers a cascade, removing the successful symbols to allow new ones to drop into the vacant spaces, potentially creating a chain reaction of multiple wins from a single spin.

Free Spins Explained

The free spins feature is accessed through the Bonus Island treasure map game. Once triggered, the round introduces an unlimited win multiplier that starts at 1x and increases by one with every successful cascade. During this mode, the Mystery Boost feature remains active, with mystery barrel symbols transforming into either standard pay symbols or gold coins to grant additional spins or instant payouts.

Bonus Island & Mystery Boost Features

The game's progression is tied to a cascade meter. Achieving four, five, or six consecutive cascades in a single turn unlocks the Bonus, Mega, or Epic Island features, respectively. These lead to a pick-and-click mini-game where you select treasure chests to reveal cash prizes or free spins. Furthermore, the Mystery Boost mechanic triggers when a cannonball symbol lands alongside mystery wooden planks; the cannonball explodes the planks to reveal matching symbols or coins, which can trigger the separate Coin Bonus for immediate rewards.
