Everything you need to know before casting your line
What makes this fishing slot a whopping good time
Minor, Major, Mega, and Grand jackpots build with every bet across the network. Triggered randomly after any base game spin, you'll open items in a bonus screen until you reveal three matching jackpot names. Higher bets increase your chances, but any jackpot can drop at the minimum $0.10 stake.
Land 3, 4, or 5 scatter symbols to trigger 10, 15, or 20 free spins. During free spins, every Wild fisherman symbol collects all Money symbol values on screen. Collect every 4th Wild to retrigger with 10 more spins and increase the collection multiplier to 2x, then 3x, then 10x.
All fish symbols are also Money symbols, taking random values every spin from 2x up to a massive 5000x your total bet. Values include 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, 1666x, 2500x, and 5000x. These get collected by Wilds during free spins.
Collect Whopper symbols on the side during free spins. Every 3 Whopper symbols you gather awards an additional 10 free spins at the end of your current round, giving you extra chances to reel in big wins with your active multiplier.
This isn't your standard fishing pokie. Big Bass It's a Whopper Jackpot Bonanza from Pragmatic Play takes the beloved Big Bass series and supercharges it with four progressive jackpots. The underwater lake setting, complete with rippling water and pine forests above the surface, creates an immersive atmosphere that keeps you engaged spin after spin.
The 92% RTP sits on the lower side, but the high volatility means you're playing for those life-changing hits rather than steady small wins. With a 5000x maximum win (excluding jackpots), a single free spins round can deliver absolutely massive payouts, especially when you hit that 10x multiplier on the third retrigger.
The free spins feature is where the real magic happens. You'll need at least three scatter symbols (the jumping bass fish with a purple glow) to trigger it. Once activated, the fisherman Wild appears on all reels, and here's the crucial bit: every time a Wild lands, it collects all Money symbol values currently visible on the screen.
What makes this feature exceptional is the Wild collection mechanic. Every Wild that lands during the feature is stored, and when you've collected four Wilds total, the feature retriggers with 10 additional spins and a 2x multiplier on all Money collections. Collect four more Wilds for another retrigger at 3x, then once more for the final retrigger at an incredible 10x multiplier.
Imagine landing a Money symbol showing 500x your bet, then a Wild collects it with the 10x multiplier active. That's an instant 5000x win, hitting the maximum cap in one go. The feature ends immediately when you reach 5000x, with remaining spins forfeited, but you walk away with the full amount.
Every spin, the fish symbols (Group of Fish, Fishing Bobber, Dragonfly, Fishing Rod, and Tackle Box) take random monetary values. The possible values range from conservative 2x bets all the way up to the maximum 5000x. During base game spins, these values sit there tantalisingly, but you can only collect them during the free spins feature when Wilds appear.
The anticipation builds when you see high-value Money symbols scattered across the reels during free spins, waiting for that Wild to land and scoop them all up. With the multiplier active on retriggers, even moderate Money values can stack into substantial wins.
Unlike the free spins which you trigger through gameplay, the four jackpots drop completely at random after any base game spin. You won't see them during free spins or bonus features. When triggered, you enter a pick-and-click screen where you open items until you reveal three matching jackpot symbols.
The jackpot you win is predetermined, so the picking game is purely for entertainment. The four levels are Minor (purple briefcase icon), Major (grey fishing rod icon), Mega (green fish icon), and Grand (orange fish icon). Your chance of winning each jackpot is directly proportional to your bet size. Betting $375 gives you much better odds than the $0.10 minimum, but importantly, even minimum bets are eligible for the Grand jackpot.
The Ante Bet option increases your wager to 15x the base bet per line, in exchange for improved scatter symbol hit frequency. For players chasing free spins triggers, this can be valuable. However, it doesn't change the RTP (still 92%) and significantly increases your cost per spin. If you're playing at higher stakes already, the Ante Bet can drain your balance quickly waiting for features.
Most experienced players recommend trying the base game first to understand the feature frequency before committing to Ante Bet, especially given the high volatility. Dead spins can stack up fast at 15x cost.
The highest-paying regular symbol is the Fishing Bobber, awarding 200x your bet per line for five of a kind. The Dragonfly pays 100x, while the Fishing Rod and Tackle Box both pay 50x for five matching symbols. The Group of Fish symbol pays 20x.
Card symbols make up the lower-value pays. Ace and King both pay 10x for five of a kind, while Queen, Jack, and Ten pay 5x each. All wins pay left to right on the 10 fixed paylines, with only the highest win per line paid out. Multiple winning lines on the same spin are added together.
Remember, during free spins, you're not really playing for line wins. You're playing for Money symbol collection by Wilds, which is where the truly big wins come from.
Pragmatic Play optimised this slot brilliantly for mobile devices. The underwater graphics, bubble animations, and smooth reel spins work flawlessly on phones and tablets. The portrait mode layout puts the jackpot meters at the top, the reels in the centre, and all controls within easy thumb reach at the bottom.
The game includes battery saver mode to reduce animation intensity, helpful for longer sessions on mobile. Sound effects and music can be independently toggled, and there's an intro screen disable option if you want to jump straight into the action on subsequent sessions.
While the potential for big wins is exciting, it's crucial to gamble responsibly. Set deposit limits before you start, take regular breaks, and never chase losses. The high volatility of Big Bass It's a Whopper means you can experience long losing streaks before hitting features.
