Big Bass Bonanza is a fishing slot from Pragmatic Play, and the studio launched it on 14 December 2020. The Big Bass Bonanza demo opens the same game in free play, with no registration and no cash stake. The free build copies the paid version, so the reels, the paylines, and the bonus rules match.
The layout keeps five reels, three rows, and 10 fixed paylines. Free play mirrors the real-money RTP of 96.71% and the same volatility, so the maths stays identical. Players test the hit rate and the bonus rhythm first, then decide on a real stake later.
Pragmatic Play supplies the free version directly, and many casino and comparison sites in the UK host it too. The mode needs no account, no deposit, and no download. Any win there counts as a practice score and carries no cash value.
Reels, Paylines and Numbers
The grid runs five reels by three rows, and all 10 paylines stay fixed in both modes. Symbols cover fishing gear, boats, bass and the Fisherman. One site lists stakes from 10p to £1 per spin in free play, and that range belongs to the host site, not to the developer.
The numbers below stay the same in free play and in real play:
- Release date: 14 December 2020 by Pragmatic Play;
- RTP: 96.71% on the developer’s own page;
- Grid: 5 reels, 3 rows, 10 fixed paylines;
- Hit frequency: roughly 33% of spins;
- Money symbol top value: 2,000x the base bet;
- Free spins on offer: 10, 15 or 20;
Free Spins and Money Collect
The scatter drives the bonus, and three of them start the free spins. Money symbols then land as fish with cash values printed on them. The Fisherman wild appears only during the feature, and it stands in for every symbol except the scatter.
The collect step decides most of the payout. The Fisherman nets every money symbol on screen and adds the combined total to the win. Values reach 2,000x the base bet inside the bonus, so one busy screen changes the whole session total.
Scatter counts set the length of the feature:
- Three scatters: 10 free spins;
- Four scatters: 15 free spins;
- Five scatters: 20 free spins;
Retriggers and Win Multipliers
Every fourth Fisherman collected in the feature restarts it with 10 extra spins. Each restart also raises a multiplier on the collected money values. Free play shows how rarely the deepest stage arrives, and that single point tells a new player plenty about the volatility.
The multiplier ladder runs in three steps:
- First retrigger: 2x on collected values;
- Second retrigger: 3x on collected values;
- Third retrigger: 10x on collected values;
The Series Next to the Original
The franchise grew into 25 titles by May 2025, and Big Bass Boxing Bonus Round followed in June 2025. Bigger Bass Bonanza, Big Bass Splash, Big Bass Bonanza Megaways, Big Bass Amazon Xtreme, Big Bass 1000, and Even Bigger Fish all keep the scatter, free spins, and collect structure. Each one then changes the grid, the hit rate, or the top win. One source cites 96.51% RTP for Big Bass Bonanza 1000, and Big Bass Bonanza Reel Action carries a 2,100x max win.
Comparison pages updated in November 2025 still treat the 2020 original as the baseline for volatility and mechanics. No change has hit its RTP or its feature rules in the past year. Updates went to the sibling titles instead.

Free Play and Real Money for UK Players
The free build loads in a browser on desktop and mobile. The whole flow takes under a minute, and the balance arrives as play credits. Keep the same stake level you plan to use with real money, and the test stays useful.
Follow these steps to test the slot without a stake:
Real-money play needs a site with a UK Gambling Commission licence, and the minimum age stays 18. Deposit caps, loss limits and time-outs sit inside every licensed account. GAMSTOP blocks UKGC-licensed sites for players who self-exclude, and BeGambleAware runs free advice lines across the UK. Set a budget first, then treat the free mode as practice only.
FAQ
What does the free mode cost?
The free mode costs nothing. It runs on play credits only, so no deposit is required. Wins stay on screen and never turn into cash.
Does free play use the same RTP?
Free play mirrors the real-money figure of 96.71% and the same volatility. The hit rate and the bonus behaviour match the paid version.
How many free spins do the scatters award?
Three scatters pay 10 free spins, four scatters pay 15, and five scatters pay 20. Each retrigger adds 10 more spins.
What does the Fisherman wild do?
The Fisherman stands in for all symbols except scatters during free spins. It also collects every visible money symbol and adds the total to the win.
Does the free version need registration?
Pragmatic Play and many UK casino sites load it with no account. A real-money account needs age checks and identity checks first.
