How the Game Plays

Big Bonus Booster by Inspired Gaming is a supercharged evolution of the classic fruit machine aesthetic. Played on an expanded 6x4 grid with 50 fixed paylines, the game features high-fidelity symbols like colorful 7s, crowns, and various fruits against a vibrant green backdrop. Winning combinations are formed by landing three or more matching symbols from left to right, with the Wild symbol substituting for all regular symbols to complete lines. While the base game offers a familiar retro feel, the presence of Diamond Scatters on every reel signals the potential for the game's more modern mechanics to take over.

Free Spins Explained

Triggering the bonus requires landing three or more Diamond Scatters. This initiates a "Match 3" pick-me round where you select tiles to reveal colored gems. The first three matching gems determine your Big Bonus value, which acts as a guaranteed win threshold for the subsequent Free Spins. Once the bonus begins, you receive unlimited free spins that continue until a single win equals or exceeds your set Big Bonus value. During this round, any Wilds that land on the middle four reels become sticky, remaining in place for the duration of the feature to help build toward that target win.

The Boost Trail & Fortune Bet

Unique to this version is the Boost symbol, which exclusively appears on the sixth reel during the bonus. Landing this symbol advances you along the Boost Trail, which can upgrade your current Big Bonus multiplier. These upgrades can push your guaranteed win target up to 100x the stake. For those looking to increase their odds, the Fortune Bet option increases the base stake in exchange for a significantly higher chance of triggering the bonus round.
