Star Boost

Star Boost — Hold & Win slot by CROCO Games. 96% RTP, high volatility, up to 6,000× max win. Integrated via one REST API.

Star Boost is built like an arena. Nine reward plaques ring the reels, jackpot plaques burn overhead, and all of them belong to the player. The hook is the Boost. Every Boost symbol pumps the board: Reward Boost fattens the prizes on the nine plaques, Jackpot Boost charges the jackpots above. So the player is not just spinning toward a win, they are building one, watching their own board swell spin after spin, knowing the bigger they bet the bigger that board grows. The tension holds because none of it pays out until Base Bonus and Jackpot Bonus symbols trigger the feature and cash in everything assembled. That delayed payoff is the retention engine: high volatility means quiet stretches punctuated by glowing, screen-filling wins up to 6,000x. For operators it is a high-ceiling neon showpiece for players who like anticipation to compound, a session that rewards patience and punishes nobody for chasing the ceiling.

Enter a world of pure neon — glowing lines, electric colour and a prize board that's alive. In Star Boost, nine reward plaques surround the reels with jackpot plaques shining above… and they all belong to you.

Every Boost symbol powers up your board: Reward Boost pumps up the prizes on your nine plaques, while Jackpot Boost charges the jackpots above the reels. Spin by spin the rewards around you grow — and the bigger you play, the bigger your board becomes.
