Booster Theme, Design & Symbols

Booster immerses players in a retro-futuristic, neon-drenched arcade world inspired by 1980s synthwave and classic video games. The backdrop features a starry skyline with glowing grids and geometric shapes, while the reels are framed by pulsing lights. The overall aesthetic is clean, colourful, and highly energetic, perfectly matching the game's name and core mechanic.

The symbols are a mix of classic slot icons and thematic gems, all rendered with a sleek, glossy finish. Low-paying symbols are stylised playing card suits (hearts, diamonds, clubs, spades) in vibrant colours. The high-paying symbols are various coloured gemstones. The most valuable standard symbol is the multi-coloured diamond. The game's Wild symbol, represented by a glowing 'W', substitutes for all symbols except the Scatter. The Scatter, depicted as a radiant sunburst, is the key to triggering the main bonus round.

Booster Bonus Features & Free Spins

The Boost Meter

The central feature of the game is the Boost Meter located to the left of the reels. Every winning combination contributes to filling this meter. Once completely filled, it automatically triggers the Booster Free Spins round. The meter can be filled multiple times in a single base game spin if cascading wins occur, offering the chance to chain free spins sessions.

Booster Free Spins

When triggered, the Booster Free Spins round awards free spins. Before the round begins, one regular paying symbol is randomly chosen to become a 'Boosted Symbol' for the duration of the feature. All instances of this symbol transform into a Mega Symbol, significantly increasing the potential for big wins. Furthermore, all Wild symbols that land during the free spins become 'Boosted Wilds,' which expand to cover their entire reel. Check the in-game help screen for the verified number of free spins and exact symbol mechanics.

Scatter Wins and Retriggers

Landing three or more Scatter symbols anywhere on the reels during the base game awards an instant payout. Landing three or more Scatters during the Booster Free Spins round retriggers additional free spins. Check the in-game help screen for the verified number of retriggered spins and any limits.
