Pragmatic Play's 5-reel fishing slot pays across 10 fixed paylines. Land scatters to trigger free spins where wild fishermen collect money from fish symbols, with wins multiplying up to 10 times. RTP 96.71% and high volatility means bigger wins come less often.

How the grid and paylines work. Big Bass Splash is a five-reel fishing slot from Pragmatic Play, released in 2022. You spin across a 3-row grid with 10 fixed paylines, where wins form left to right from the leftmost reel. The game is built on collecting money values shown on fish symbols during free spins, triggered by scatters. High volatility means wins come less often and can be much bigger. Three matching symbols at minimum form a winning line, though the red truck pays from just two symbols.
Know your bet range before spinning. This slot suits players ready for longer stretches between wins and willing to stake £0.10 to £5 per spin. The high volatility and potential for substantial payouts attract players chasing bigger rewards rather than frequent small wins. If you prefer steady, regular wins or have a tight session budget, the bonus-focused design and top prize of £25,000 at maximum bet may feel too volatile. Conversely, the free spins round with its escalating multiplier system rewards patience through the base game.
When does the free spins bonus start? Free Spins form the heart of each round. Land three or more scatters in the base game to trigger the bonus. Once active, a fisherman wild symbol appears across all reels and collects the cash values displayed on fish symbols. Every fourth wild collected retriggers an additional 10 free spins and raises the collection multiplier up to a maximum level of 10x, meaning your final collected total multiplies accordingly. Random events—dynamite, a hook, and a bazooka—add or shift symbols to keep the round dynamic.

Before your first spin, understand how each round plays out from bet to result
How wild collection builds your multiplier. The fisherman wild appears on all reels and collects random money values shown on fish symbols, ranging from 2x to 5000x your bet. Every fourth wild collected retrigggers 10 more free spins and raises the multiplier: level 2 equals x2, level 3 equals x3, level 4 equals x10.
What happens when two scatters land? Five reels across three rows spin with 10 fixed paylines, and wins pay from left to right starting from the leftmost reel. Land exactly two scatters to trigger a random respin where scatter reels move down, or a hook pulls a reel up to reveal another scatter.
MoreThe other Big Bass games range from 96.50% to 96.52% RTP and offer maximum wins between 5,000x and 25,000x your stake.

Bonus timing stays unpredictable. The bonus round lands when the reels decide it, not on any schedule you can spot. You might wait five spins or fifty before free spins begin.
Don't count on the RTP for today. Your next spin could win big or lose your stake. The 96.71% RTP describes long-term play across thousands of players, not what happens in your session.
Can you actually win that much? Winning £25,000 at a £5 bet is mathematically possible but happens so rarely that you should never expect it. Most sessions end without reaching anywhere near that ceiling.
MoreYour highest stake on this slot is £5, which can return up to £25,000 if the maximum win lands on your spin.

RTP is a long-run average calculated across many thousands of spins. The figure shown applies only to the standard game and holds true when the total stakes across all players reaches a very large number.
