Bonus Features
Pragmatic Play designed Big Fish Bonanza with clear bonus mechanics that add extra features throughout the base game and bonus rounds. The main feature activates when 3 or more scatters land, triggering a Free Spins round with multipliers and collector symbols. As part of the modern Big Bass slot release cycle, this combination of Free Spins and collection mechanics remains a recognizable feature setup in the game.

Free Spins
The Free Spins feature triggers when 3, 4, or 5 Scatter symbols land, awarding 10, 15, or 20 spins respectively. During the round, every Wild fisherman collects Money Symbols and helps retrigger the bonus after every 4th appearance. This mechanic gives players a chance to reach 3 retrigger levels with increasing multipliers.

Money Symbol Feature
During Free Spins, fish-shaped Money Symbols land with random cash values. Each time a Wild appears, it collects all visible Money Symbols on the reels. The more Wilds you collect, the higher the chance to reach up to 10x multiplier on future collections.

Pragmatic Play expanded its fishing-themed slot series following the success of Big Fish Bonanza. The portfolio includes several other popular titles featuring different mechanics, prize levels, and bonus formats:

- Big Bass Splash – Adds random modifiers during Free Spins, including extra Wilds and more Scatters. Higher variance than the original and a 5,000x max win.
- Big Fish Bonanza Megaways – Uses the Megaways engine with up to 46,656 ways to win. RTP is slightly lower at 96.70%, but volatility is significantly higher.

Pros and Cons of Big Fish Bonanza
Players who prefer traditional slot gameplay with a clear fishing theme and straightforward bonus mechanics are the main audience for Big Fish Bonanza. Developed by Pragmatic Play, the game combines five reels, ten paylines, expanding wilds, and a free spins feature with multiplier symbols. Its high volatility means that understanding the bonus mechanics and potential variance is important before playing for real money, particularly during longer sessions.
| Pros | Cons |
| Clear fishing-themed gameplay with simple slot mechanics | High volatility can result in longer periods without significant wins |
| Free Spins feature adds multipliers and additional win potential | No progressive jackpot or traditional jackpot feature |
| Five reels and ten paylines make the layout easy to understand | RTP of 96.71% is below some higher-returning slots |
| Bet range from £0.10 to £250 suits different bankroll sizes | Maximum win is capped at 2,100x the stake |
| HTML5 compatibility supports play on mobile and desktop devices | Bonus features depend heavily on landing the required symbols |
| Wild symbols can expand and contribute to multiple winning combinations | Basic base-game gameplay may feel repetitive during longer sessions |
| Demo mode is available at many online casinos without requiring a real-money wager |
Players familiar with fishing-themed slots will recognise the core format of Big Fish Bonanza, but its combination of expanding wilds, free spins, and multiplier symbols gives the game more variety than a basic payline slot. The base game uses a straightforward five-reel structure, while the bonus features provide additional opportunities for larger combinations. As a high-volatility title, individual results can vary considerably between spins, making the game’s mechanics and risk profile important factors to consider before playing with real money.
Big Fish Bonanza vs. Fishin’ Frenzy
Big Fish Bonanza and Fishin’ Frenzy are two of the most recognisable fishing-themed slots in the UK. Both use a 5×3 layout, feature fisherman Wilds, and offer Free Spins as their primary bonus mode. The visual themes are similar, making them equally appealing to casual players.


Despite the similarities, there are clear differences between the two. Big Fish Bonanza delivers a higher volatility experience with retrigger levels and multipliers, while Fishin’ Frenzy keeps things simple with static payouts. The max win is also slightly higher in Big Bass, reaching 2,100x, compared to 2,000x in its counterpart.
