Pragmatic Play's High-Volatility Fishing Slot
Big Bass Bonanza Reel Action combines high-volatility fishing thrills with a unique Wild collection mechanic that builds multipliers up to 10x during free spins. Every 4th Wild you land retriggers the feature with increasing power.
Land 3, 4, or 5 Scatter symbols (the iconic Bass in a golden circle) to trigger 10, 15, or 20 free spins. During the feature, Fisherman Wild symbols appear on all reels and collect every Money symbol value visible on screen.
The real power lies in the retrigger system. Every 4th Wild symbol you collect during free spins triggers a retrigger with escalating multipliers:
Ante Bet mode increases your stake by 50% but significantly boosts Scatter frequency on the reels for more natural feature triggers. Alternatively, Buy Free Spins for 100x your bet to instantly trigger the bonus with a guaranteed 3-5 Scatters landing (determining your starting spin count). The Buy option is disabled when Ante Bet is active.
Unlike standard slots where Wilds simply substitute, Big Bass Bonanza Reel Action's Fisherman Wild has a dual function during free spins. When a Wild lands, it instantly hoovers up every Money symbol (fish or frog) visible anywhere on the reels at that moment. If you land multiple Wilds on one spin, each one collects the full value of all Money symbols present.
The game tracks your Wild count across all free spins. Hit your 4th Wild, and you're awarded an immediate retrigger: 10 additional spins plus a 2x multiplier. The 8th Wild brings another 10 spins and bumps the multiplier to 5x. The 12th Wild maxes you out with a third retrigger at 10x multiplier. This creates explosive potential in the later stages when high-value Money symbols appear with a 10x boost.
The Bobber (fishing float) is the premium symbol, paying 5,000x your line bet for five of a kind and uniquely awarding wins from just two symbols. The Fisherman pays 2,500x for a full line and doubles as the Wild during free spins. Dragonfly and Tackle Box both award 1,250x, whilst the Fish Dinner symbol pays 500x.
Lower-value card symbols (A, K, Q, J, 10) each pay 250x for five matching. All symbols pay left to right on adjacent reels starting from the leftmost position across the 10 active paylines. With bets ranging from £0.10 to £375, the 2,100x max win cap translates to a maximum payout of £787,500 at top stake.
Big Bass Bonanza Reel Action sits at the maximum 5 out of 5 volatility rating. This means wins arrive less frequently than medium or low variance slots, but when they hit—especially during retriggered free spins with active multipliers—they can be substantial. Budget for longer dry spells between bonus triggers. The 96.50% RTP is consistent across base game, Ante Bet, and Buy Feature modes.
High-volatility slots suit players comfortable with risk and variance. You might burn through 50+ spins without a significant return, then land a free spins round that delivers 200x or more in a single feature. The retrigger mechanic amplifies this volatility: reaching that third retrigger with 10x multipliers can turn modest Money values into four-figure payouts.
Pragmatic Play's Big Bass series has become a staple in UK online casinos, and Reel Action refines the formula with the retrigger multiplier system. The progression from 2x to 5x to 10x creates genuine anticipation as your Wild count climbs. Unlike slots where free spins feel static, here every Wild matters because it pushes you closer to the next retrigger threshold.
The underwater theme is executed with polish: deep blue gradients, caustic light effects, and bubble animations create an immersive freshwater fishing atmosphere. The Scatter symbol—a largemouth bass in a golden sunset frame—is instantly recognisable. Even the low-value card symbols have a glossy, bubble-like aesthetic that fits the aquatic setting.
Built on Pragmatic Play's HTML5 platform, Big Bass Bonanza Reel Action runs smoothly on iOS and Android devices without downloads. The 5×4 grid is touch-optimised, and all controls (bet adjustment, autoplay, settings) are accessible via a bottom toolbar. The game includes Battery Saver mode to reduce animation intensity on mobile, plus options to toggle ambient music, sound effects, and intro screens.
Autoplay supports up to 100+ automatic spins with configurable stop conditions. Turbo Spin and Quick Spin modes accelerate reel animations for faster sessions. The game rules are detailed across seven in-game pages covering paytable, features, and controls—helpful for understanding the retrigger mechanic before staking real money.
