About Bigger Bass Bonanza
Bigger Bass Bonanza is Pragmatic Play's direct sequel to Big Bass Bonanza — same 5x3, 10-payline format with an upgraded fisherman collect mechanic. The key addition is multiplier fishermen: during free spins, fisherman wilds now carry 2x or 3x multipliers that apply when collecting fish values. Multiple fishermen on the same spin multiply together, creating significantly larger collect payouts than the original.
Theoretical RTP is 96.45%, with Pragmatic's three-tier deployment. UK casinos commonly deploy at the second tier (approximately 94.45%). The multiplier fishermen increase the game's volatility compared to the original — the base collect mechanic returns less frequently but produces larger payouts when multiplied fishermen land.
For players choosing within the Big Bass franchise: Big Bass Splash (96.71%) has the highest theoretical. The original (96.45%) and Bigger Bass (96.45%) are tied. Splash's lives system adds more mechanical depth. Bigger Bass's multiplier fishermen add concentrated win potential. At the same deployment tier, Splash is the mathematically superior choice.
