Reel Kingdom / Pragmatic Play · 2020Overview
Big Bass Bonanza is a 5×3 fishing adventure from Pragmatic Play's Reel Kingdom studio. Land three or more scatter symbols to unlock free spins, where multipliers stack and chase the 2,100x ceiling.
How it plays
Spin the reels across 10 fixed paylines with stakes from £0.10 to £250. The base game hits frequently enough to keep sessions moving, but the real money lives in free-spin triggers — high variance means you'll see long droughts between bonus rounds.
The bonus round
Three scatters land free spins where multipliers attach to winning combinations and carry across consecutive spins. Each free-spin win climbs the multiplier ladder; the bonus feeds itself if you land more scatters mid-round. This is where the 2,100x max materialises.
Who it's for
Anglers who want a respectable 96.71% RTP paired with high-volatility swings — suited to players with a session bankroll to weather 50+ spins between bonus triggers.
Avoid if
You prefer frequent small wins or play in short bursts — Big Bass Bonanza demands patience and a buffer for variance.

Scatter triggers are infrequent in base play — expect every 40–80 spins on average at standard stakes. High volatility means dry runs are normal; the bonus round is where profits come from.
Yes. Land three more scatters mid-bonus to add extra spins and reset the multiplier climb, extending your session and multiplier growth.
