Pragmatic Play's fishing-themed slot uses Megaways mechanics with Free Spins and Hold & Spin modes, returning 96.70% over time, with high volatility where wins arrive less often but can be substantially larger.

Reels that change shape. This fishing-themed slot runs on a Megaways grid where the number of ways to win shifts with each spin. The main reels can show between 2 and 6 symbols each, while an independent top strip adds extra rows of wild symbols and blanks. Wins cascade down the reels and refill from above until no new combinations form. Released in 2023 by Pragmatic Play, Big Bass Hold & Spinner Megaways combines high volatility with its Tumble feature, meaning wins come less often but can be much bigger when they land.
Big swings, patient players. This slot works best for players comfortable with longer dry spells between wins and who have a budget for higher stakes. The minimum bet is NZ$0.20, and you can bet up to NZ$240. If you prefer frequent small payouts or want to stretch your balance, the high volatility and premium features mean this game may not suit your style. The Hold & Spinner and Free Spins bonuses can be bought at a cost, so knowing your budget matters here.
Big Bass Hold & Spinner Megaways locks symbols in. The Hold & Spinner bonus round defines how a winning session can unfold. When this mode triggers, special symbols lock in place across the reels while others spin, and new matching symbols can land and lock alongside them. This stacking mechanic can build larger wins than the base game allows. Combined with the Tumble feature, locked symbols stay put while other reels cascade and refill, creating a momentum that shapes the round's potential.

Set your bet, watch the reels work, and see where wins and features take you.
What do Free Spins do for you? During Free Spins, the grid expands and symbols lock in place across multiple spins. You keep any symbols that land in the hold positions while the reels spin again, building your winning combinations without staking more.
Locked reels with repeated spins. Hold & Spinner freezes landing symbols in their positions and respins the remaining reels. Each symbol that lands and holds stays locked while you continue to respins, giving you chances to build larger wins.
Big Bass Hold & Spinner Megaways shifts its reels constantly. Big Bass Hold & Spinner Megaways uses a grid where reels 1 and 6 show 6 symbols fixed, while reels 2 to 5 range from 2 to 6 symbols. The topmost row holds only wild symbols and blanks, randomly locked or unlocked each spin. Winning symbols tumble away and reels refill from above until no more wins form.
RTP is a long-run average calculated over a very large number of spins. When you play with a bought bonus, the RTP shown applies only to that mode.
You'll know how to start playing this slot with or without risking your money.
Bonus timing is random. When the bonus round arrives depends on chance alone. No pattern or timing shows when it will trigger, so you cannot count on it happening within a set number of spins.
Does RTP guarantee a result. One session's result stays random whatever the RTP says. The RTP applies over many thousands of spins across all players; your own session can swing either way from that average.
Will I hit the maximum. The maximum win of NZ$4,800,000 is a ceiling you might never see. It sits at the top of the possible range; most sessions finish far below it, and reaching it stays extremely rare.
Big Bass Splash 1000 reaches x25,000 and 96.52% RTP; the others top out at x5,000 with RTPs between 96.50% and 96.51%.
Launch into Free Spins without waiting for them to trigger naturally. You'll pay NZ$1,000 at a NZ$10 bet and enter the bonus round with locked symbols already in play on the grid.
Jump straight to Hold & Spinner for NZ$1,200 at a NZ$10 stake. Big Bass Hold & Spinner Megaways locks winning symbols in place so they stay across multiple spins, building bigger payouts.
You've found the slot and want to know what sets it apart before you start playing.
How much should I stake? Decide how much you can afford to spend before your session starts, and stick to that amount. Your budget stays separate from money you need for essentials.
Stop before the urge builds. Plan when you will stop playing, whether you are winning or losing. A big win can tempt you to keep going, but that moment is when discipline matters most.
Limits: do they help? Use your account's deposit limits and loss limits to enforce your own boundaries. These tools make it harder to overspend in the heat of the moment.
Your power to step back. If the game stops being enjoyable or you are chasing losses, take a break. Self-exclusion and cooling-off periods are there for you to use.
