Pragmatic Play's high-volatility 5x4 fishing slot with Free Spins and Money Collect features, 96.71% RTP, hits top wins of 4000x your bet.

How the 5x4 grid works here. Bigger Bass Bonanza is a fishing-themed slot from Pragmatic Play released in 2021. It runs on a 5-reel, 4-row grid with 12 fixed paylines that pay left to right from the leftmost reel. The game combines money-valued fish and standard symbols across the base game. Its high volatility means wins arrive less often but can be much bigger. The free spins bonus is the signature feature, where a wild fisherman collects cash values from the screen when it lands.
Who this game suits best. This slot suits you if you have a larger bankroll and patience for longer dry spells between payouts. The high volatility and 96.71% RTP appeal to players chasing bigger wins rather than steady small returns. Bet ranges from A$0.12 to A$240, so you can start small or go large. The free spins mode is where the real payoff happens. If you prefer frequent small wins or have a modest budget, a lower-volatility game may feel less frustrating.
Free spins: where the money collects. Free Spins shape every round here. Land 3, 4 or 5 scatters to trigger 10, 15 or 20 spins. During the bonus, the wild fisherman appears only on these reels and collects all money values on screen when it lands. Every 4th wild retriggers 10 more spins with a multiplier that boosts your cash collection to 2x, 3x or 10x. The round caps at 4000 times your bet, so a A$10 bet can reach A$40,000 in free spins alone.

What happens when the Fisherman lands? Three, four or five Scatters launch 10, 15 or 20 spins. The Fisherman Wild lands only here, collects all cash values on screen and retriggers the round with multipliers up to x10. Your total bonus payout caps at 4000 times your bet.
Start your round in base mode. Twelve paylines run left to right on adjacent reels from the left. Money symbols and regular icons pay per the paytable. The Fishing Boat pays from just two matching symbols on a payline.
Big Bass Blast, Big Bass Football Bonanza and Big Bass Trophy Catch all pay 96.50%, while Big Bass Raceday Repeat reaches 96.51%. Big Bass Splash 1000 offers the highest maximum win at 25000x bet.
The RTP is an average calculated across thousands of spins over a long period. It shows how much of every dollar staked the game returns to players on average. Your actual results in any session will vary.
Bigger Bass Bonanza bonus timing. The Free Spins round may take five spins or fifty to arrive. No pattern reveals when Scatter symbols will land, so you cannot rely on bonus timing in any session.
Can I predict this session's result? The RTP of 96.71% describes the long-term average across millions of spins. Your next session is random, and you may win less, more or nothing regardless of that average.
Will I win the maximum? The maximum win reaches A$960,000 at the highest bet, but only very rarely across thousands of players. Treating it as likely is how you lose money.
You'll spin the same 5x4 grid and land the same symbols as the real game, but your balance stays untouched. Watch how the free spins trigger and the cash collection works before you stake anything.
Play demoYour stakes are real, your wins are yours to keep, and the high volatility means you chase that 4000x bonus win with genuine skin in the game. Each spin counts toward the rounds you want.
