Big Bass Bonanza at Nine Casino: what you need to know
A Pragmatic Play fishing game on five reels where free spins trigger through scatter symbols and Fisherman Wilds collect multiplied payouts. RTP is 96.71 percent, with high volatility meaning wins arrive less often but can be substantially larger.
Get to know this ocean-themed game
How the 5-reel game is built. Big Bass Bonanza is a fishing-themed slot set across 5 reels and 3 rows. Released in 2020, it runs on 10 paylines that move left to right from the leftmost reel. With high volatility, wins come less often and can be much bigger when they land. The game features a Money Collect mechanic alongside free spins, multipliers and wild symbols that work together to create winning combinations on the reels.
Who this game fits best. Big Bass Bonanza suits players comfortable with longer stretches between wins but who want the chance of significant payouts. The game ranges from NZ$0.10 to NZ$250 per spin, so both modest and high-stake players can find their level. Its free spins mode and multiplier features appeal to those who enjoy watching bonus rounds unfold, rather than players who prefer steady smaller wins across many spins.
When the bonus round transforms the reels. Free spins reshape how the game plays. Landing 3 or more scatters triggers 10 to 20 spins depending on scatter count, and the Fisherman Wild symbol becomes active on all reels. When this wild lands, it collects the value of Money symbols around it. Every fourth wild you collect adds 10 more free spins and escalates the Money multiplier, up to 3 times. This retrigger mechanic can extend your bonus and multiply your payouts significantly.

When the reels change and multiply
Scatters launch the bonus round. Land three or more Scatters to enter Free Spins: three grant 10 spins, four grant 15 spins, five grant 20 spins. During Free Spins, the Fisherman Wild lands on every reel and collects MONEY symbol values. Every fourth Wild collected adds 10 more spins and boosts the MONEY multiplier—up to three times, with multipliers reaching x2, x3, and x10.
Big Bass Bonanza base game setup. The base game runs on a five-by-three grid across ten paylines that work left to right, starting from the leftmost reel. Only standard pay symbols appear here—the Fisherman Wild does not land during base game spins.

Big Bass Bonanza cannot tell you what comes next
Triggers come without warning. The Scatter that triggers Free Spins arrives at random. You might spin fifty times without landing three, or land them on your second spin. No pattern tells you when it arrives.
Does RTP promise my result? Your money across one session follows no rule. The RTP of 96.71% describes only what happens across thousands of players over thousands of spins. Your session can end early or run much longer.
Can you reach the maximum win? The maximum win of NZ$525,000 exists only as a ceiling. It arrives so rarely that you cannot plan a session around reaching it or expect it within any timeframe.
