Bigger Bass Bonanza is the sequel that actually earns the “bigger” in its name. Developed by Reel Kingdom under the Pragmatic Play banner and released in September 2021, it takes the original Big Bass Bonanza formula, adds an extra row, pushes the max win from 2,100x to 4,000x, and drops you back at the water with sharper bait. The fishing theme is unchanged. The maths isn’t, and that’s what matters.

After plenty of sessions across the Big Bass series, this one sits in a good spot: familiar enough that you know what you’re walking into, different enough that it doesn’t feel like a palette swap. The core loop still revolves around collecting fish values through wild fishermen during free spins, but the expanded grid and bigger multipliers give the bonus rounds real stakes. Whether those stakes pay out in your favour is a separate matter.

Technical Features

Bigger Bass Bonanza runs on a 5×4 grid with 12 fixed paylines. The default RTP is 96.71%, above the industry average, and that’s a genuine positive. One caveat: operators can dial it down to 95.67% or 94.62%, so check the in-game info panel before you start. If your casino is running the 94.62% version, you’re effectively playing a different game.

Volatility is high. Pragmatic rates it 4 out of 5, but in practice it plays closer to a 5. Hit frequency sits around 12.53%, so roughly one in eight spins pays something, but those returns are heavily weighted toward the bonus. The base game can go cold for a long time.

⚠️Warning

Many UK casinos cap the maximum bet at £2 to £5 depending on your age bracket, which limits the theoretical max payout to around £8,000-£20,000 in practice. If you’re looking for high-stakes fishing, this isn’t it.

Bets run from 10p to £240 per spin on the game itself, though UK-licensed sites typically enforce much lower caps. Mobile play works well on both iOS and Android, with the 5×4 layout holding up fine in portrait mode.

Design and Theme

Where the original Big Bass Bonanza went fully underwater, this one pulls the camera up to the surface. You’re looking at a sun-baked shoreline: tall buildings, palm trees, open water behind the reels. It’s bright, cartoon-styled, and cheerful without being irritating. The five transparent reels are separated by rising bubbles, which keeps the fishing motif without cluttering the symbols.

The soundtrack stays low-key and doesn’t grate over a long session, which is more than can be said for a lot of slots in this genre. It won’t win any atmosphere awards, but it doesn’t overreach either. Reel Kingdom’s house style leans toward clean, accessible presentation rather than cinematic flair, and this fits that approach.

Symbols and Paytable

Low-value symbols are the standard card suits, present mainly to fill space between features. The real value sits in the themed symbols: a fishing box, flies, fishing rods, and a boat. Five boats on a payline pays 200x your stake, which tops the base paytable.

The wild is a fisherman who only appears during free spins, substituting for everything except the fish scatter. Scatter symbols are the fish, and they do two jobs: triggering the bonus and carrying cash values during it. Money fish can hold values up to 400x your bet, and those are what the fisherman wilds collect on landing.

Bonus Features

Bigger Bass Bonanza keeps it simple. There’s one feature: free spins. Land three or more fish scatters and you’re in.

3 scatters award 10 free spins. 4 scatters give you 15. 5 scatters hand over 20.

During free spins, the wild fisherman is the engine of everything. When he lands alongside money fish, he collects every fish value showing on screen. That’s the Money Collect mechanic. When it fires with several high-value fish in view, the payout can jump sharply.

Above the reels, a collection bar tracks your wild fishermen. Every four wilds you accumulate retriggers the bonus with 10 more free spins and bumps a multiplier on all fish collections. First retrigger: 2x. Second: 3x. Third: 10x. That 10x tier is where the 4,000x max win lives. Getting there means landing a sustained run of wilds across an extended bonus. That’s rare. Don’t treat the ceiling as the typical result.

💡Tip

The retrigger multipliers are cumulative with the fish values. If you reach the 10x multiplier tier with high-value fish still appearing, that’s when Bigger Bass Bonanza shows its real potential. Patience through the earlier retrigger stages pays off.

One more thing: the Bonus Buy option exists in some markets but is blocked in the UK. You’ll have to trigger free spins the old-fashioned way.
