Big Bass Bonanza 1000 is Pragmatic Play's April 2025 revision of its best-known fishing slot: 5 reels, 3 rows, 10 paylines, high volatility and a maximum win of 20,000x the bet. UK stakes run from £0.10 to £5.00. The headline number to check before you spin is the RTP, because three figures are in circulation: a maximum of 96.51%, with 94.51% and 92.01% listed at two UK lobbies. The game itself never tells you which build you are on - the in-game paytable does.
Big Bass Bonanza 1000 RTP and Key Figures

How Big Bass Bonanza 1000 Plays
Big Bass Bonanza 1000 plays on a 5x3 grid with 10 fixed paylines and stakes from £0.10 to £5.00 in the UK. Wins form left to right, and the paytable tops out at 5 to 200 times the bet for five of a kind. The base game is deliberately plain: no wilds appear in it, and the fishing money symbols only show their teeth once free spins begin. If you have played the original, this will feel identical at first - the difference is the size of the numbers hiding in the bonus round.

Free Spins: Where the 20,000x Lives
Landing 3, 4 or 5 scatters awards 10, 15 or 20 free spins; when only two scatters land, the game can randomly reel in a third to start the feature anyway. During free spins, wild fishermen collect every visible money symbol - values range from 2x to 1,000x the bet - and every fourth wild retriggers the round with 10 extra spins and a win multiplier that steps up to a 10x maximum. That multiplier ladder on 1,000x money symbols is what pushes the theoretical ceiling to 20,000x the bet.
Wilds and money symbols also have a random chance to appear after each free spin, so the round can build even without a lucky starting grid. It remains a high-volatility design: most bonus rounds will not climb the ladder, and the text on this page should be read as a description of the rules, not of expected results.
Feature buy prices
Where the operator offers purchases, the regular free spins buy costs 100x the bet and the super free spins buy costs 450x. Note that at least one UK casino lists the game with no bonus buy at all - another reason the same title can play differently between lobbies. Buying a feature concentrates risk; it does not change the game's long-run return.
Is There a Big Bass Bonanza 1000 Demo?
We do not currently link a free demo for Big Bass Bonanza 1000. In Great Britain, free-to-play versions require age verification at 18+, which is why this site links out to demos rather than embedding them. The provider publishes the full rules of the game on its official page, and the paytable at your licensed casino remains the definitive reference for the build you are playing.
What we like
- Very high published ceiling: 20,000x the bet
- Simple, fully published rules - scatters, spin counts and retriggers are all documented
- Money symbols up to 1,000x make the bonus round easy to read
- Wide UK-friendly stake range from £0.10
What to keep in mind
- Three different RTP builds in circulation, from 92.01% to 96.51%
- Base game has no wilds and little action before the bonus
- High volatility - the ceiling is theoretical, not typical
- No free demo link on this page yet
Verdict
By the criteria we publish - openness of the figures, availability of an official demo, clarity of the rules for a newcomer - Big Bass Bonanza 1000 does well. The provider documents every mechanic, the retrigger ladder is easy to follow, and the paytable states its own limits plainly. The deduction is for the RTP spread: with 96.51%, 94.51% and 92.01% builds all live in the UK market, two players can buy the same game at meaningfully different prices without either of them knowing. The rating describes the game as a product, not your odds: this is entertainment with a house edge, and the ceiling of 20,000x is a rules fact, not an expectation.
