Big Bass Bonanza Guide: Rules, Free Spins, Money Fish and Retriggers

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Big Bass Bonanza is the Reel Kingdom fishing slot, released through Pragmatic Play, that started a long run of sequels. The base game is a plain 5 reel, 3 row, 10 line slot. The real game lives in the free spins, where a fisherman wild reels in the cash values printed on fish symbols.

We loaded the official demo, read every rules page and played it on a $2 bet. There is no bonus buy in this original version, so we spun until the free spins landed on their own. They did: 4 scatters, 15 free spins, one retrigger and a $208 total. This guide explains the rules behind that round and what the numbers in the game info actually say.

How Big Bass Bonanza works

The grid is 5 reels by 3 rows with 10 fixed paylines. All symbols pay from left to right on adjacent reels, starting from the leftmost reel, and only the highest win is paid per line. Wins on several lines are added together.

The paytable at a $2 bet tops out with the fishing float: $400 for five, $40 for four, $10 for three and $1 for two. It is the only symbol that pays for two of a kind. The fishing rod pays $200 for five, the dragonfly and the tackle box pay $100 each for five, and the fish money symbol pays $40 for five. The card royals A, K, Q, J and 10 all pay the same: $20 for five, $5 for four and $1 for three.

There are no cascades or multipliers in the base game. You spin, lines pay, and you wait for scatters. Space and Enter start and stop a spin, and holding Space switches to turbo spin.

Special symbols: wild, scatter and money fish

The scatter is the leaping bass on a sunset badge. It appears on all reels, and 3 or more of them start the free spins.

The wild is the fisherman holding a fish. Read this part of the rules carefully: the wild appears on all reels during the free spins round only. You will not see it in the base game. It substitutes for every symbol except the scatter.

The fish are money symbols. On every spin each fish takes a random cash value, and the possible values are 2x, 5x, 10x, 15x, 20x, 25x, 50x and 2,000x total bet. In the base game those values are just decoration on top of the normal fish line pay. They only get collected in the free spins. In our demo spins we saw fish land with $20 and $10 tags at a $2 bet, which matches the 10x and 5x steps.

Free spins: trigger, wild collection and retriggers

Land 3 or more scatters anywhere to win free spins. Three scatters give 10 free spins, four give 15 and five give 20. Special reels are in play during the feature.

During free spins every fisherman wild that lands collects the values of all money fish on the screen. All wilds that hit are also counted on the meter across the top of the reels. Every 4th wild collected retriggers the feature for 10 more free spins and raises the multiplier on money collection: 2x for the first retrigger, 3x for the second and 10x for the third. The extra spins are played after the current batch ends, and the multiplier applies to those retriggered spins. After the third retrigger the feature cannot retrigger again.

There is one more rule worth knowing. Randomly, when only 1 wild is on the screen at the end of a free spin, fish money symbols can appear in random positions. That gives a lone wild something to collect.

Our demo bonus round, spin by spin

We played at a $2 bet with the $100,000 demo balance. The base game went quiet for a few spins, then four scatters landed and the game awarded 15 free spins.

The early spins built the total slowly. A wild landed next to several fish and took the win to $40 with 8 spins left. By the last spin of the first batch we had $168, and the wild meter had filled to four. That triggered the first retrigger screen: extra 10 free spins, and wilds now worth x2.

The x2 spins added another $40. The biggest single moment was a $32.53 big win in that second batch. The round ended on a final screen showing $208, which is 104x our $2 bet. That is one bonus round, not an average, and plenty of rounds pay far less. It does show how the retrigger multiplier changes things: a single x2 wild next to a $10 fish is worth $20 on its own.

Is there a bonus buy?

No. This original Big Bass Bonanza has no buy feature and no ante bet in the demo we played. The only way into the free spins is landing 3 or more scatters. Later games in the series added buy options, but they are separate titles with their own rules.

RTP, max win, volatility and bet range

The rules screen lists a theoretical RTP of 96.71%. The game config sets the maximum win at 2,100x bet, with the odds of hitting it given as 1 in 3,880,481. If a free spins round reaches 2,100x, the round ends right away, the win is paid and any remaining spins are forfeited.

In the version we loaded, the rules page labelled the game as low volatility. Treat that label with some care in practice: most of the value sits in a bonus that can take a while to arrive, and the 2,000x fish value is the one that makes the top end possible.

The demo bet runs from a $0.10 minimum to a $250 maximum. The game opens at $2. Real money versions at casinos can show a different RTP setting, so check the rules screen in the game you actually play.

Our verdict

Big Bass Bonanza is simple, and that is the appeal. The base game is a thin 10 line slot, so you are really playing for the free spins and the wild meter. The retrigger ladder of 2x, 3x and 10x gives the feature a clear goal, and our demo round showed how quickly one retrigger can lift a total. The 2,100x cap is modest next to newer slots, and there is no bonus buy, so patience matters. For a first look at the series, the free demo is the right place to start.
