Big Bass Bonanza Slot Sites: Top Picks to Play Online in UK
Written By Jamie Smith
Fishing-themed slots are always some of the most played games at UK online casinos, with the Pragmatic Play hit Big Bass Bonanza arguably the best known of the lot. Using a money symbol collector symbol that is now very common among slots, Big Bass Bonanza was arguably ahead of its time and has been copied often since.
The best Big Bass Bonanza slots often allow players to test out Pragmatic Play games and those from other providers in demo mode, while free spins might be provided as a new customer welcome bonus to allow players to test games risk-free.

Full Rules & Information About the Big Bass Bonanza Online Slot
There is nothing too creative about the main game area used on Big Bass Bonanza, with 10 paylines in play across the 5×3 grid of reels designed by Pragmatic Play and Reel Kingdom.
Big Bass Bonanza Factsheet
| Reels | 5 |
| Rows | 3 |
| Paylines | 10 |
| Multipliers | Yes |
| Gamble Feature | No |
| Free Spins | Yes |
| Bonus Games | Yes |
| Jackpot | No |
| Min Bet | £0.10 |
| Max Bet | £5 |
Multipliers kick in to supercharge the potential payouts and the free spins bonus round is without a doubt the highlight of Big Bass Bonanza, which does not have a jackpot prize up for grabs but boasts a low minimum bet.
Big Bass Bonanza Symbols & Payouts
The low-paying symbols on Big Bass Bonanza are the usual card icons (10, J, Q, K, A). The potential payouts on the Pragmatic Play hit slot are then boosted for higher-paying icons such as a dragonfly, bait and a fishing rod.
Three matching icons are needed on a payline to make a winning combination, while the wild – which is represented by a grinning fisherman holding his catch of the day – can also help in by swapping in for other slots symbols.
- All symbols: 12
- Highest-Paying Symbol Fishing Rod
- Wilds: Wilds
- Paylines Pay: Left to Right
- Maximum Win: 2,100x the stake size
Big Bass Bonanza Bonuses & Features
Slot features on Big Bass Bonanza are centred around the free spins bonus round, which is triggered by getting at least three Scatter symbols. Players get 10 free spins for three Scatters, which goes up to 15 free spins for four Scatters and 20 free spins for those who are lucky enough to get five Scatters from the same spin.
Fish money symbols can appear in the bonus game, but they are only won if a fisherman wild appears to ‘catch’ them. Within the Big Bass Bonanza bonus round, a collect meter also sits at the top of the reels.
Every time a spin includes fish being caught, one space fills up on the meter, which has the power to retrigger more free spins to extend the length of the bonus game and boost the potential payouts it offers.
If the free spins game sees the player get the game’s maximum win – with the amount set at 2,100x the stake size – then the bonus round immediately ends.
Similar Games & Best Alternatives
New slots often use a money collector system similar to that in the Big Bass Bonanza bonus game, with great options at UK online casinos including the likes of Gold Rush: Cash Collect, a branded game based on a hit TV show.
Pragmatic Play and Reel Kingdom have provided various slot sequels following up the success of Big Bass Bonanza. The festive-themed Christmas Big Bass Bonanza is a simple reskin, but more complex options include Bigger Bass Bonanza and Big Bass Bonanza Megaways, both of which are recommended.
Go Fishing with Big Bass Bonanza
Fishing has become one of the most common themes for new slots at UK online casinos, which is largely down to the success of Big Bass Bonanza. But while the game has a lot of rivals within the fishing-themed slots category, the original remains among the best in the business.
Having the chance to retrigger the free spins bonus round helps to make Big Bass Bonanza a great game, though it is worth noting it has medium-high volatility and a relatively low top payout of just 2,100x the stake size.
