Fishing Theme and the Base Game
Pragmatic Play released this slot in 2020, and it has a relaxed lakeside look: bright water, tackle-box symbols and a cheerful fisherman in the corner. It runs on a 5x3 layout, so it is easy to read even if you are new to video slots.
The base game is fairly quiet. You spin, look for matching symbols and wait for fish money symbols to show up. The big action is saved for the bonus round, which is where the slot earns its reputation.

Fish Money Symbols and Their Cash Values
What the fish carry
Money symbols are the fish that land on the reels with a cash value attached to them. On their own, in the base game, they are just a pleasant sight. Their real purpose comes alive when the bonus begins.
Why the values matter
Each fish value is a prize waiting to be collected. A screen full of fish is exciting, but it only pays if a fisherman wild is there to reel them in.
- Fish symbols show a cash value directly on the symbol.
- Values are only collected when the fisherman wild lands.
- Check the in-game paytable for the exact value range, as it can be shown in your stake terms.

Free Spins: How the Fisherman Wild Collects Prizes
Getting into the bonus
The free spins round is the centrepiece of the slot. The in-game help screen shows exactly what triggers it and how many spins you receive, so read it before your first spin.
The collect mechanic
During free spins, the fisherman wild acts as a collector. Whenever he lands, he gathers the values of every fish money symbol visible on the reels and adds them to your win.
That makes the round feel very different from the base game. A spin with several fish and no fisherman pays nothing extra, while one with both can turn a modest round into a big one.
- Land the bonus trigger to start the free spins.
- Watch for fish money symbols appearing on the reels.
- Hope the fisherman wild lands at the same time to collect their values.
Retriggers and Multiplier Upgrades
Extending the round
The slot has a retrigger feature, so the free spins can be extended while the round is running. Longer rounds mean more chances for the fisherman to meet a screen full of fish.
Boosting what he collects
Collected wilds can also upgrade the value of later catches in the round. The exact number of wilds needed for each upgrade, and the size of each boost, are listed in the game's paytable, so check it in-game rather than relying on memory.
The top win of 2,100x is most likely to come from a long free spins round where retriggers and upgrades stack together.
Big Bass Bonanza Volatility and RTP
The game's RTP is 96.71%. RTP is a long-run theoretical average across a huge number of spins, so it says nothing about a single session. Your own results can sit far above or far below it.
Volatility is high. Expect stretches where little happens, followed by occasional bigger moments, mostly inside the bonus. The 2,100x maximum win is a ceiling, not a typical result.
Quiet base game, loud bonus round: that is the whole personality of this slot.
Because of the high volatility, smaller stakes tend to give you more time in the game. That is a general principle for this kind of slot, not a promise of any outcome.

FAQ
What does the fisherman wild do in Big Bass Bonanza?
During the free spins round, the fisherman wild collects the cash values of all fish money symbols showing on the reels and adds them to your win. Without him, the fish do not pay out on their own. That is why spins where the fisherman and several fish land together are the most valuable.
How do retriggers work in the free spins round?
The slot includes a retrigger feature that can extend the free spins while the round is running. Extra spins give the fisherman more chances to collect fish values. The exact trigger conditions and spin counts are set by Pragmatic Play and shown in the game's paytable, so check them in-game.
What is the maximum win in Big Bass Bonanza?
The maximum win is 2,100x your stake. It is a theoretical ceiling reached only in rare, very strong bonus rounds, not something to expect in a normal session. With high volatility, most results will be far smaller, and long quiet spells are normal.
What is the RTP of Big Bass Bonanza?
The RTP is 96.71%. This is a long-term theoretical average over a very large number of spins, not a guarantee for any single session. Short-term results can differ a lot, especially on a high-volatility slot like this one.
