Big Bass slots now come in so many versions that picking one takes some homework. The series started with Big Bass Bonanza in December 2020, and Pragmatic Play, working with its studio partner Reel Kingdom, has kept adding new versions ever since. By the time Big Bass Splash 1000 arrived in December 2025, it was already the 31st game in the series, and new titles followed in 2026.
That volume makes the games hard to tell apart. Most share the same fisherman, fish, and free spins idea, so the differences sit in the grid, the top prize, the extras and the published RTP.
Below we line up ten of the main titles. Every figure comes from Pragmatic Play’s game pages or, where Pragmatic doesn’t list it, from at least two independent review sites.
How the Big Bass Series Works
Nearly every game in the series is built around one bonus. You land three or more scatter symbols to trigger free spins (usually 10, 15 or 20 for three, four or five scatters). During those spins, fish symbols land carrying random cash values, shown as multiples of your bet. On their own, they do nothing. When a fisherman wild lands on the same spin, he collects the value of every fish on the screen.
Each fisherman you land also counts toward a retrigger meter. In the classic design, every fourth wild gives you 10 more free spins and raises a multiplier on collected fish values to 2x on the first retrigger, 3x on the second, and 10x on the third.
Newer games add layers on top. Some load modifiers before the free spins, some bring in a fisherman when fish land without one, and the 1000 editions push fish values up to 1,000x your bet. Every spin is still decided by a random number generator, so you can’t time or predict it. If RTP and volatility are new terms to you, our guide to RTP and volatility in slots explains both.

The Main Big Bass Slots, Title by Title
Big Bass Bonanza
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 2,100x
- Free spins: 10, 15 or 20 for 3, 4 or 5 scatters, with fish values up to 2,000x
This is the template every other title borrows from. Review sites list its volatility as medium to high, and with no modifiers or side features, it’s the easiest version to learn.
Bigger Bass Bonanza
Key Features
- Format: 5 reels, 4 rows, 12 paylines
- Max win: 4,000x
Think of it as the original on a taller grid. The extra row and two extra paylines change the base game a little, and the top fish value doubles to 4,000x.
Big Bass Bonanza Megaways
Key Features
- Format: 6 reels with up to 46,656 ways to win
- Max win: 4,000x
- Free spins: 10 to 25, depending on whether 3, 4, 5, or 6 scatters land
Megaways fans are the obvious audience. Reel heights change every spin, and a sixth scatter adds a 25-spin tier that the 5×3 games don’t have.
Big Bass Splash
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 5,000x
- Modifiers: zero to five can be added before the free spins begin, such as extra fish, extra wilds, or extra spins
Thanks to the random modifiers, two bonus rounds can start very differently, and fish values can reach 5,000x.
Big Bass Hold & Spinner
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 10,000x
- Two bonuses: fisherman free spins, plus a hold and spin round triggered by three coins in the base game
In the hold and spin round, the coins turn sticky, and you start with four lives, which reset whenever another coin lands. Diamond symbols can also appear. A Megaways spin-off, Big Bass Hold & Spinner Megaways, uses six reels with 147,456 ways and a 96.70% published RTP.
Big Bass Amazon Xtreme
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 10,000x
- Pre-bonus choice: you pick upgrades before free spins, such as more fish, more fishermen, or starting at level two
Here you get some say in how the bonus starts, instead of leaving every modifier to chance.
Big Bass Christmas Bash
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 5,000x
- Second chances: if only two scatters land, a respin or a hook can bring in the third
Snow and Christmas trimmings aside, the real change is in the bonus. When fish land without a fisherman during the bonus, dynamite, hook, or bazooka features can place one on the reels. A bonus buy costs 100x your bet where it’s offered.
Big Bass Bonanza 1000
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 20,000x
- Fish values: up to 1,000x, with random wilds and fish added after free spins
The classic Bonanza look stays, but the math behind it is much bigger. Pragmatic Play lists the top win at 20,000x, up from 2,100x for the original. Review sites rate it as very high volatility, so expect longer dry spells.
Big Bass Splash 1000
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 25,000x
- Modifiers: a fishing animation before free spins can unlock up to five, including starting the feature at level two
Splash 1000 pairs the modifier system from the 2022 game with 1,000x fish values. Its 25,000x top prize is the highest of the ten games in this table.
Big Bass Halloween Splash 1000
Key Features
- Format: 5 reels, 3 rows, 10 paylines
- Max win: 20,000x
- Pumpkins: pick from six pumpkins before the bonus, and pumpkin symbols on reel five can add upgrades during it
This is the 1000 format with a gentler ride. Launch coverage lists its volatility as medium, against high for Splash 1000, with a lower ceiling. Released on 12 October 2026, it’s the newest game in the series.
Which Big Bass Slot Should You Choose?
New to the series? Start with Bonanza or Splash. They’re the easiest to follow, both carry a 96.71% published RTP, and Splash adds variety through its modifiers without changing the core rules.
If you want the largest top prize, look at the 1000 editions, with 25,000x on Splash 1000 and 20,000x on Bonanza 1000. Those ceilings come with heavier volatility, and most sessions finish nowhere near them.
Hold and Spinner is the pick for something different, since its coin bonus plays nothing like the fisherman round. Amazon Xtreme lets you choose the bonus setup, and the seasonal releases put a new theme on familiar rules.
Compare RTP too. Hold & Spinner and Amazon Xtreme publish 96.07%, below the original’s 96.71%. Our list of Pragmatic Play slots with the highest RTP shows how they compare with the rest of the catalog. Whichever you pick, set a budget first and play for entertainment, not income.
Conclusion
All the Big Bass slots share one idea: fish that carry cash and a fisherman who collects it during free spins. What changes is the grid, the ceiling, and the extras. The original Bonanza is still the simplest version, Splash adds random modifiers, Hold & Spinner brings a second bonus, and the 1000 editions lift the top prize to 20,000x and 25,000x.
Before playing for real money, try the demo, check which RTP version your casino runs, and remember that every result is random.
Frequently Asked Questions (FAQs)
Big Bass slots are a series of fishing-themed games from Pragmatic Play and Reel Kingdom, starting with Big Bass Bonanza in 2020. Most share a free spins round where fish symbols carry cash values and a fisherman wild collects them. The series has since grown to more than 30 titles, including Megaways, Hold & Spinner, 1000, and seasonal versions.
Of the ten games compared here, Big Bass Splash 1000 has the highest listed max win at 25,000x your bet. Big Bass Bonanza 1000 and Big Bass Halloween Splash 1000 follow at 20,000x. Hitting these figures is very rare.
It refers to fish money symbols that can carry values up to 1,000x your bet. The 1000 editions also offer much higher max wins, such as 20,000x on Big Bass Bonanza 1000 versus 2,100x on the original.
Pragmatic Play publishes 96.71%. Casinos can run lower RTP settings of the same game, so check the game’s rules or information screen where you play.

No. Every Big Bass game uses a random number generator, so each spin is independent of the last. Modifiers and retriggers change how a bonus can play out, but they don’t make any result predictable.
