Big Bass Splash is a fishing-themed video slot built by Reel Kingdom and published by Pragmatic Play, released on 6 June 2022. It sits in the same Big Bass family as Big Bass Bonanza, with the familiar bearded fisherman and an underwater backdrop. If you want to know how to play Big Bass Splash slot UK, the key is understanding how an ordinary base-game spin connects to the free spins round, because that is where the money symbols and multipliers actually pay out.
Below I'll walk through a round, explain the bonus engine, and flag the two things beginners often miss: the RTP versions and the stake ranges.
The basics: grid, lines and a single spin
The game uses a 5×3 grid — five reels, three rows — with 10 fixed paylines. Wins form when three or more matching symbols land on adjacent reels along a line, counting from the leftmost reel.
The symbols rank like this:
- Monster truck — the highest-paying standard symbol
- Fishing rod — next
- Tackle box, float and other kit — mid value
- Playing cards (10, J, Q, K, A) — the lowest payers
In the base game, the money fish symbols and the fisherman carry no special power. They sit there looking promising, but they only come alive once you're inside the free spins. That's worth remembering: the base game mostly exists to land you three scatters.
Setting your stake
Stake ranges differ by operator, which trips people up. Some sources list £0.10 up to £250 per spin; others show a narrower £0.10 to £5 band, which looks operator-specific. Before you spin, check the figure shown in your own game window rather than assuming. There's an Autospin (autoplay) function if you'd rather let a set number of spins run, and it's sensible to decide a budget and a session length before you start.
How you trigger the free spins
The bonus is scatter-driven. Land three, four or five scatter symbols anywhere on the reels and you get:
- 3 scatters → 10 free spins
- 4 scatters → 15 free spins
- 5 scatters → 20 free spins
There's a near-miss helper too. If two scatters land in the base game, they can stick to the reels and randomly set off a free re-spin, giving you another go at landing that third scatter. It doesn't always fire, but when it does it's a second chance at no extra stake.
Inside the free spins: the fisherman does the work
This is the part that defines the game. During free spins, the money fish symbols show cash values, ranging all the way up to 5,000x your bet. The fisherman now becomes a Wild and a collector.
When a Fisherman Wild lands on a spin, it sweeps up the cash value of every money fish visible on that same spin. One wild landing alongside three fish collects all three. No wild on the spin means the fish values stay on screen for that turn but aren't paid — you need a wild to land to bank them.
The money symbol values you can see during the feature run through a long ladder: 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, 1666x, 2500x and up to 5,000x.
How the retriggers and multipliers compound
The free spins have four levels, and you climb them by collecting wilds. Every fourth wild you collect retriggers the feature with 10 extra free spins and applies a multiplier that only affects wins from the fish cash symbols:
| Wilds collected | Extra spins | Fish multiplier |
|---|---|---|
| 4th wild (1st retrigger) | +10 | 2x |
| 8th wild (2nd retrigger) | +10 | 3x |
| 12th wild (3rd retrigger) | +10 | 10x |
The multiplier tops out at 10x. So the big outcomes come from stacking high-value fish on screen while you're on the top level and a fisherman lands to collect them at 10x. That chain — many fish, a wild to collect, a high multiplier applied — is the route to the headline figure.
The maximum win
The maximum win is 5,000x your bet. You reach it through the free spins by collecting enough high-value money fish, with the retrigger multipliers lifting those fish wins. It's rare, and the game's maths reflects that.
RTP and volatility
Two RTP figures appear across sources: 96.71% on one, 94.60% on another. That isn't a mistake — Pragmatic Play supplies slots in more than one RTP version, and operators choose which to run. A gap of two percentage points matters over time, so if your casino displays the RTP in the game's info panel, it's worth a look before you commit a session to it.
Volatility is rated very high (5 out of 5 on one tracker). In plain terms, expect long gaps between meaningful wins and most of the value concentrated in the bonus. A high-volatility slot can empty a balance quickly during a cold run, which is the main reason to size your stake modestly and play within limits you've set in advance.
Bonus buy and the demo
The feature list includes a Buy Free Spins function, where you pay a multiple of your stake to jump straight into the bonus rather than waiting for three scatters. Reviews also mention extra feature modifiers — Re-spin, Multiplier, Hook, Dynamite and Bazooka symbols. Availability of bonus buy varies by jurisdiction and operator, so it won't always be on offer.
The game runs on desktop and mobile — smartphone, tablet or PC — and a free demo is available. The demo is the sensible place to learn the collect mechanic without staking real money: trigger the free spins, watch how a wild sweeps the fish, and count the wilds up to a retrigger so the multiplier logic clicks.
Big Bass Splash versus the other titles
People mix up the franchise entries. Big Bass Splash is the 2022 title with a 5,000x cap described above. Big Bass Splash 1000 is a later, higher-variance version: it offers up to 25,000x win potential, money symbols worth up to 1,000x, as many as five bonus game modifiers before the free spins, a Super Free Spins bonus buy priced at 450x, and an RTP of 96.52%. Bigger Bass Splash is a separate sibling again. If a figure looks far bigger than 5,000x, you're probably reading about the 1000 edition rather than the original.
Trying it yourself
To see the engine in one go: open the demo, set a small stake, and use Autospin to reach the free spins. Once inside, track two things — the cash values on the fish and how many wilds you've collected. When your fourth wild lands and the 2x kicks in, you'll see exactly how the base spin, the collector and the multiplier tie together. That single bonus round tells you more about the game than any payout table.
