Crop Booster series
The Crop Booster series is Espresso Games' farm-themed bonus franchise, built on multipliers and collection mechanics rather than one fixed reel format. Rooster Booster introduced the line in 2023 as a compact 3x3 slot with eight paylines, respins, pot collection and a bonus buy. Its 0.2 to 25 bet range suits the smaller screen and direct bonus structure.

Crop Booster expands the format to 5x3 and 20 paylines, then replaces the stripped-back rooster setup with free spins, symbol collection, a pick-a-prize round, random multipliers, fixed jackpots, stacked symbols and respin locking wins. Medium-to-high volatility and a 1,000x maximum give it a defined risk profile, while the larger feature set turns the farm theme into a more conventional modern bonus game.
