Casino-Game Review: Big Bass Bonanza by Pragmatic Play
With its bright, cheerful graphics and fresh aquatic theme, Big Bass Bonanza attracts both beginners and seasoned players alike. The game is designed around five reels and three rows, offering 10 fixed paylines. The symbols include colourful fishing rods, tackle boxes, and various fish species, alongside classic playing card icons.
Gameplay and Features
The main attraction of Big Bass Bonanza is its Free Spins feature, triggered by landing three or more scatter symbols (depicted as a fishing boat). During free spins, every fish caught adds a cash prize, and the fisherman’s catch multiplier can increase up to 10x—multiplying all wins during the feature. Furthermore, retriggers of free spins are possible, which delights players looking to extend their sessions and boost jackpots.
The game also includes a wild symbol (the fisherman), which substitutes for other symbols to create winning combinations. Betting ranges are well-balanced to suit casual players and high rollers, starting from as low as 10p per spin up to £250 in some UK-licensed casinos.
