How fishing slots work
Fish symbols carry cash values. During free spins, a fisherman wild "collects" every fish value on screen. Collecting enough fishermen usually unlocks extra spins and multipliers.

From Fishin' Frenzy to Big Bass
Blueprint's Fishin' Frenzy (2014) set the template: fish with cash values and a fisherman who collects them in free spins. Pragmatic Play and Reel Kingdom's Big Bass Bonanza (2020) added retriggers with multipliers, and the Big Bass series has since grown into one of the biggest slot franchises, with sequels such as Big Bass Splash and Big Bass Vegas 1000.
