Big Bass Bonanza at Rocketspin Casino gives you the numbers upfront
Pragmatic Play's fishing-themed slot runs on 5 reels with free spins bonuses, a 96.71% RTP and high volatility where wins come less often but can be much bigger.
Big Bass Bonanza: a fishing slot with high volatility
How the reels are arranged. Big Bass Bonanza puts you on a 5-reel, 3-row fishing expedition where wins form across 10 paylines from left to right. Released in 2020 by Pragmatic Play, this ocean-themed slot combines fishing imagery with high volatility mechanics. Wins come less often but can be much bigger when they land. The base game features standard pay symbols and a Money Collect mechanic alongside Wilds and Scatters, setting up the conditions for Free Spins where the real depth of the game unfolds.
When you have the right bankroll. This slot suits players who can handle long stretches between wins and have a bankroll for higher stakes. The high volatility means your money plays for longer stretches before a bonus arrives, so you need patience and a bet size that fits your session budget. At NZ$2, a typical spin costs less than a coffee, but at NZ$10 you're staking more per turn. The Free Spins round is where the volatility pays off—that's where you'll chase the bigger payouts.
Where big wins come from. Free Spins reshape the entire game. Land 3 or more Scatters in the base game to trigger them: 3 gives 10 Free Spins, 4 gives 15, and 5 gives 20. During Free Spins, the Fisherman Wild appears on every reel and collects the values of Money symbols it lands on. Each Wild you collect escalates the Money multiplier and can retrigger the round up to 3 more times, adding 10 Free Spins each time. This feature is where the 2100x maximum win lives.

How the reels and features work together
Free Spins and the Fisherman Wild
Big Bass Bonanza bonus launch. Three or more Scatters land to start this bonus: 3 Scatters give 10 Free Spins, 4 give 15, and 5 give 20. During Free Spins, the Fisherman Wild appears on all reels and collects Money symbol values on landing. Every fourth Wild collected adds 10 more spins and escalates your Money multiplier, up to three times. The maximum win during Free Spins reaches 2100 times your stake.
Spinning without the Wild. The base game uses a 5 by 3 grid with 10 paylines running left to right from the leftmost reel. Standard pay symbols fill the reels, but the Fisherman Wild does not appear here. You spin and match symbols across paylines to form wins, with no special multipliers or collections during this mode.
Which outcomes stay unknown no matter what?
When does the bonus arrive? The bonus round arrives by random chance. No pattern, streak or bet size makes Free Spins come sooner. You might trigger them in your first spin or after many rounds.
Does RTP promise my outcome? Your session result is never guaranteed by the RTP figure. One player may win; another may lose the same amount staked. The return rate applies to millions of spins, not your next session.
Will you hit the maximum? The maximum win of NZ$525,000 is a ceiling you may never reach. Most sessions end far below it. Even during Free Spins with multipliers, the result depends entirely on which symbols land.
Should you play the demo first?
Why try the demo first?
The demo gives you a chance to see how the reels behave, what the symbols pay, and when Free Spins land without your money at risk. You learn the rhythm of the game before you decide to stake.
Play demoPlaying with real stakes
When you are ready, you place real stakes and the slot works exactly as the demo showed. Wins and losses are real, and Free Spins can lead to the larger payouts the bonus round offers.
