Pragmatic Play has just released the 25th title in its iconic fishing-themed franchise, and it’s the biggest one yet, Big Bass Bonanza 1000 is now live at top-rated slot sites across the UK. Featuring the classic angler, familiar symbols, and a pumped-up Free Spins feature, this latest addition promises bigger fish and even bigger wins, up to 20,000 x your total bet.

- RTP: 96.51%
- Max Win: 20,000x
- Volatility: Very High
- Stakes: 10p to £5
- Release Date: 24 April 2025
Played on a 5x3 grid with 10 paylines, Big Bass Bonanza 1000 sticks to its roots but introduces bigger payout potential and fresh twists. The RTP clocks in at an impressive 96.51%, with very high volatility and a hit frequency of 13.19%. Betting starts at just 10p and reaches up to £5 per spin, giving players plenty of flexibility to reel in those big wins.
Free Spins Feature Supercharged
The action truly kicks off with the Free Spins feature. Triggered by 3 or more Big Bass Scatters, this bonus round is where the magic happens. Fisherman Wilds collect fish money symbols worth up to 1,000 x bet each. Every fourth Fisherman retriggers the round, handing out more free spins and boosting the fish multiplier up to 10x!
Random extras like the Bazooka, Hook, and extra fish drops add even more juice to your bonus rounds. And if that wasn’t enough, players outside the UK can use the Buy Free Spins or Ante Bet options to speed things up (note: RTP versions may vary).
Classic Look, Legendary Potential
The underwater visuals will feel familiar to fans of the series, though this version features a green tint reminiscent of Big Bass Amazon Xtreme. Symbols range from royal playing cards to dragonflies, tackle boxes, and the top-paying fishing float (worth 200x for five).
While visually it plays the nostalgia card, the 20,000 x bet max win potential is a record-setter for the Big Bass franchise. The gameplay, although largely unchanged, is elevated by the extreme volatility and sky-high payout ceiling. If you’re a fan of demo slot games with straightforward mechanics and serious win potential, this is one to try.
Still deciding? You can take Big Bass Bonanza 1000 for a spin with the Big Bass Bonanza 1000 demo slot version: it’s the perfect way to test the waters before betting real cash.
