Big Bass Bonanza is Pragmatic Play's fishing-themed classic that launched an entire franchise of Big Bass sequels. The original remains the blueprint: a 5x3, 10-payline slot with a unique money fish mechanic that gives free spins a different feel from standard slot bonuses.
Big Bass Bonanza — base game.
The game's star is the fisherman wild symbol — land this on the reels and he automatically collects all fish symbols visible, converting each into a cash prize instantly. In free spins, this mechanic becomes even more powerful, with multipliers applied to each collection. It's straightforward, satisfying, and delivers the best RTP of any slot on this list at 96.71%.
Big Bass Bonanza has a base RTP of 96.71% — verified from Pragmatic Play's official game math. This is the theoretical return-to-player over millions of spins, meaning for every $100 wagered, the game returns $96.71 on average over the long run.
| Variant | RTP | Notes |
|---|---|---|
| Standard | 96.71% | Full RTP — available at most reputable casinos |
| Reduced variant | ~94% | Operator-configured — legal but less player-friendly |
| Low variant | ~88% | Found at some licensed operators — avoid if possible |
Pragmatic Play allows operators to configure reduced RTP versions of the game. The mechanics and visuals are identical — only the math changes. Always open the game information panel (the ⓘ or ≡ icon inside the game) before playing and confirm the RTP shown matches 96.71%.
How does the original compare to the rest of the franchise?

The original Big Bass Bonanza and Megaways version offer the highest RTPs in the franchise. If maximising return-to-player is your priority, these two are your best picks from the series.
The fisherman symbol acts as both a standard wild (substituting for all paying symbols) and a collector — when he appears, he automatically sweeps every fish symbol visible on the reels and pays out their individual cash values instantly. In the base game this delivers immediate cash prizes; in free spins, the same collection is amplified by the active multiplier. A single fisherman landing on a fish-heavy grid can pay significantly above the standard win from a payline combination.
Fish symbols across the 5-reel, 10-payline grid carry randomised cash values between 1x and higher multiples of your bet. They don't need to align on paylines — their value is paid out whenever the fisherman wild collects them. The random value assignment means a single spin can produce wildly different outcomes depending on the fish values generated, which is the primary source of the game's high volatility within the 96.71% RTP framework.
During the free spins feature, fisherman wilds carry multiplier values of 2x, 5x, or 10x. This multiplier applies to the total value of all fish collected on that spin — not just to one symbol. A 10x fisherman collecting five fish with a combined value of 50x your bet delivers a 500x payout from a single spin. Multiple fishermen can land in a single free spin, and their multipliers combine. This is the mechanism behind the 2,100x max win ceiling.
Big Bass Bonanza offers direct access to the free spins feature via Bonus Buy. The cost is typically 100x your current stake for 10 free spins — the same number awarded by the natural scatter trigger. Given the 96.71% RTP (one of the highest in the Pragmatic Play catalogue), the bonus buy return is mathematically competitive with natural play. Note that Bonus Buy is unavailable in the UK and other jurisdictions where the feature is restricted by licence.
Landing 3, 4, or 5 scatter symbols triggers 10 free spins. The free spins feature is where Big Bass Bonanza truly delivers — during this phase, every fisherman wild that appears carries a multiplier (2x, 5x, or 10x) applied to all fish money values collected on that spin.
A single spin with a 10x fisherman collecting multiple high-value fish symbols can generate hundreds of times your bet in a single action. The 2,100x max win reflects the ceiling of what stacked multipliers and maximum fish values can deliver. Additional scatters during free spins retrigger the feature, and combined with the 96.71% RTP, this is consistently one of the best-value high-variance slots available.
Big Bass Bonanza — bonus round.
Not all casinos run Big Bass Bonanza at the standard 96.71% RTP — Pragmatic Play allows operators to configure reduced variants. The difference between 96.71% and an 88% variant is substantial over time: on $1,000 in wagers, the standard RTP returns ~$967 in theory vs ~$880 at the minimum tier. That's $87 less per $1,000 wagered, purely from the operator RTP setting.
To confirm the RTP at any casino: open Big Bass Bonanza, click the ⓘ (information) or ≡ (menu) icon inside the game, and navigate to the game details or paytable. The RTP should be listed there. If it shows below 96.71%, the casino is running a reduced variant.

Yes — Big Bass Bonanza is classified as High volatility by Pragmatic Play. Despite the 96.71% RTP, the variance means the money fish mechanic can produce very different outcomes across sessions. The combination of high RTP and high volatility is unusual and makes it one of the best long-session value plays in the Pragmatic Play catalogue.
The Big Bass Bonanza max win is 2,100x your stake. This is achieved when multiple fisherman wilds with 10x multipliers collect maximum-value fish symbols during the free spins feature. While lower than more recent slots in the franchise (Big Bass Amazon Xtreme goes to 5,000x), the original's 96.71% RTP means the path to significant wins is mathematically better calibrated.
The original Big Bass Bonanza (96.71%) and Big Bass Bonanza Megaways (96.72%) share the highest RTP in the franchise. All newer entries including Big Bass Amazon Xtreme (96.06%) and Big Bass Vegas Double Down Deluxe (96.04%) have lower standard RTPs. If RTP is your primary criterion, the original or Megaways version are the best picks from the series.
