Dive into the ultimate underwater fishing adventure from Pragmatic Play. Collect Wild symbols during free spins, hook Money symbols worth up to 5,000x your bet, and ride the waves to retriggerable bonuses with 10x multipliers.
This isn't just another fishing slot—it's a high-volatility wave ride with layered mechanics, progressive multipliers, and genuine win potential up to 5,000 times your stake.
Every Wild symbol that lands during free spins collects all Money symbol values visible on screen. Collect four Wilds to retrigger with 10 more spins and an increased multiplier.
Colourful fish carrying values from 2x up to a massive 5,000x your total bet. These values are only collected when a Wild lands—but when they do, the payouts stack quickly.
When Mystery wave symbols hit, all of them transform into the same random paying symbol, creating instant multi-line wins and setting up potential big cascades.
Randomly triggered after any base game spin, the Jackpot Bonus offers four tiers—Grand, Mega, Major, and Minor—awarded through a reveal mechanic. Higher bets increase your chances.
Landing three or more Scatter symbols—the leaping bass fish on a wooden badge—triggers the free spins round, the centrepiece of Big Bass Surf's Up. You'll receive 10, 15, or 20 spins for three, four, or five Scatters respectively.
During free spins, Wild symbols appear on all reels. Each Wild that lands collects every Money symbol value visible on that spin. The crucial mechanic: every fourth Wild you collect retriggers the feature with 10 additional spins and increases the multiplier applied to all collected Money values.
After three retriggers, you cannot retrigger further, but you'll be collecting Money values with a 10x multiplier active—this is where the slot's maximum win potential reveals itself.
Big Bass Surf's Up includes two random events during free spins that inject additional volatility:
Big Bass Surf's Up operates on a 5-reel, 3-row grid with 10 fixed paylines paying left to right. The slot is classified as high volatility (5 out of 5), meaning wins occur less frequently but carry greater weight when they land. The RTP sits at 92.00% for both base game and Ante Bet mode.
The maximum win is capped at 5,000x your total bet (excluding jackpots). If your total win in a round reaches this cap, the round immediately ends, you're awarded the 5,000x payout, and all remaining features are forfeited. This is standard practice for high-volatility Pragmatic Play slots and ensures responsible payout structures.
The Ante Bet option increases your total stake by 50% (from 10x to 15x bet per line) in exchange for a higher chance of landing Scatter symbols. For example, a £20 base bet becomes £30 with Ante Bet active. This doesn't change the RTP—still 92.00%—but it does alter the distribution, making free spins more frequent at the expense of a higher cost per spin. It's a choice for players who want more feature action and are willing to pay for it.
The paytable is divided into high-value thematic symbols and low-value card ranks. The Surfer Van is the premium symbol, paying £50,000 for five of a kind on a £250 stake (200x). The Beach Ball, Fishing Rod, Cooler Box, and Seafood Platter follow in descending value.
Low-value symbols—Ace, King, Queen, Jack, and Ten—are rendered as translucent, frosted letters in purple, blue, red, green, and gold respectively. Five Aces or Kings pay £2,500 (10x), while five Queens, Jacks, or Tens pay £1,250 (5x).
Money symbols appear as colourful cartoon fish displayed on golden backgrounds with a cash value shown beneath. Possible values are 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, 1666x, 2500x, or 5000x your total bet. The values are randomised each spin, and only collected when a Wild lands.
The Jackpot Bonus can trigger randomly after any base game spin (not during free spins). It's a reveal mechanic: you open items on a bonus screen until you match three symbols of the same jackpot tier—Grand, Mega, Major, or Minor. Once matched, you win that progressive jackpot.
Your chances of triggering the Jackpot Bonus increase proportionally with bet size. A £250 stake has a significantly higher probability than a £0.10 stake, though any bet above the £0.10 minimum is eligible. The jackpots are progressive, fed by a percentage of each participating bet, and reset to a seed value after being won.
Big Bass Surf's Up immerses you in a split underwater and above-water scene. The upper portion shows a vibrant sunset with gradients of orange, pink, and golden yellow, while the lower portion transitions into turquoise and deep blue underwater tones. Coral reefs frame the reels in bright purples, pinks, and greens. A sea turtle swims lazily behind the reels, a hammerhead shark silhouette lurks in the background, and a seagull perches on the reel frame.
The surfer character—a bearded man in a red beanie, sunglasses, and yellow swim trunks—serves as the Wild symbol during free spins. The aesthetic combines laid-back surf culture with the thrill of deep-sea fishing, creating a relaxed yet engaging atmosphere.
This slot suits players who appreciate high volatility and are comfortable with longer dry spells in exchange for the chance at substantial payouts. The retriggering free spins with escalating multipliers reward patience and bankroll management. If you enjoy the original Big Bass series or similar collection-based mechanics from Pragmatic Play, this iteration adds enough new elements—Mystery symbols, enhanced random events, and the jackpot layer—to justify a spin.
The 92.00% RTP is below industry average, so approach this as a high-risk, high-reward session rather than a grinding slot. Budget accordingly and consider the Ante Bet only if you're prepared for increased spend per spin.
Gambling should be entertaining, not a way to make money. Only gamble with money you can afford to lose. Set limits on your spending and stick to them. If you feel gambling is becoming a problem, seek help immediately.
Big Bass Surf's Up is a high-volatility slot with significant win potential but also substantial risk. Please gamble responsibly and be aware of the risks.
