Pragmatic Play's fishing slot plays across 5 reels and 4 rows with 12 paylines. Free spins collect money values via a wild fisherman symbol, triggering multipliers up to 10x. The standard game returns 96.50 per cent of stakes, with high volatility.

Five reels, fishing theme. Bigger Bass Splash drops you into a fishing scene across five reels and four rows. The slot runs on 12 fixed paylines from left to right, and it launched in February 2025. Fish symbols land with random cash values attached to them each spin. The fisherman wild appears to collect these values during the bonus round, and wins here come less often but can be substantially larger—fitting a high-volatility design.
Is this slot right for you? This slot suits you if you're comfortable with stretches between wins and have a stake to match its volatility. You can bet from 10p up to the maximum of £5 per spin. The 96.50% RTP applies when you play the standard game in the base mode. If you prefer steady smaller wins or play small stakes, the longer gaps between payouts may frustrate you more here than on a gentler slot.
Watch the wild collect and multiply. Free Spins reshape how a round plays out. You trigger them with three or more scatters—three gives 10 spins, four gives 15, and five gives 20. During free spins, every wild that lands collects all the cash values from fish symbols visible on screen at that moment. These collected values stack up and multiply by your current level (starting at 1x, rising to 2x, 3x, or 10x). Every fourth wild you collect advances both the multiplier and adds 10 more spins.

Understand what happens at each stage before you make your first bet
How free spins trigger. Land three or more scatters to start free spins. Three scatters award 10 spins, four award 15, five award 20. Each wild that lands collects all money values visible on screen. Every fourth wild collected retriggers 10 additional spins and boosts the multiplier from 1x to 2x to 3x to 10x.
Watching the reels spin. Five reels spin across 12 fixed paylines, left to right. Fish symbols land with random money values attached to each one every spin. Win combinations form when three or more matching symbols line up on a payline. The base game runs until you land enough scatters to enter the bonus round.
Gather fish values with wilds. During free spins each wild symbol that lands sweeps up all money values from fish symbols on screen at that moment. Collected amounts stack throughout the entire bonus round and multiply by your current level, which climbs as more wilds land. Random events with dynamite, hooks and wipeouts keep fish and the fisherman appearing together.
Free spins timing stays hidden. Free spins land randomly throughout your session. Some players trigger the bonus quickly; others spin for much longer without seeing it. There is no pattern to when or how often scatters will appear.
One session stays unpredictable. Your first session, your next session, and every session after will give results you cannot forecast. The 96.50% RTP describes what happens across millions of spins, not what you will see in the time you play today.
Treat the maximum as a ceiling. The maximum win of £25,000 is a ceiling set by the game, not a target. Reaching it happens so rarely that your play will almost certainly fall far below it. Treat it as a theoretical figure, not an expectation.
The Big Bass series ranges from 96.50% to 96.52% RTP, with maximum wins between £25,000 and £125,000 across five fishing-themed titles.
