Big Bass Splash free spins are worth about 9.67p each at 10p a spin, so 100 spins (£10 of play) return roughly £9.67 on average at the 96.71% RTP. No partner credits spins on Splash itself, but PlayOJO's 80 no-wagering spins are on its sister game Big Bass Bonanza, which has the same RTP and a lower max win.
Each 10p Big Bass Splash spin averages about 9.67p back; the house edge is 3.29%.
Splash and Big Bass Bonanza share a 96.71% RTP; Splash's max win is 5,000x against 2,100x.
PlayOJO's 80 spins at 10p on Big Bass Bonanza (£8 of spins) average about £7.74, with no wagering.

Big Bass Splash free spins and the Big Bass family
Big Bass Splash is one of the Big Bass series from Reel Kingdom, a studio whose games are distributed by Pragmatic Play (opens in a new tab). The series began with Big Bass Bonanza on 14 December 2020 and now spans many titles. When people search for Big Bass Splash free spins they usually mean one of two things: casino spins played on the game, or the free spins round inside it.
This page covers both, and it is one of the few slots where a partner offer comes close, because PlayOJO's welcome spins are on Big Bass Bonanza. Our free spins hub compares every offer, and the studio's other games are on Reel Kingdom free spins.

Because the RTP is identical, a 10p spin on either game has the same average value. A higher max win means a little more of that value sits in rare large results, so Splash's results spread slightly wider. For a promotional batch of spins, the offer's terms matter far more than which of the two games it uses. Other variants, such as Bigger Bass Bonanza and Big Bass Bonanza Megaways, have their own figures.
What Big Bass Splash free spins are worth at 10p
Multiply the number of spins by 10p and then by 96.71% to get the average return. The difference is the house edge, 3.29% here.

How to trigger free spins on Big Bass Splash
The Big Bass games are known for a signature mechanic: during the free spins round, a fisherman wild collects the cash values shown on fish symbols. That description comes from Reel Kingdom's series as a whole. The number of scatters needed, the number of free spins and any extras specific to Splash are listed in the game's help screen, so read it for the version your casino runs.
Open Big Bass Splash and select the information button.
Find the free spins page and note how many scatter symbols start the round.
Check how many spins are awarded and how fish cash values are collected.
Look for any retrigger or level-up rules and any extra modifiers.
Confirm the RTP and the 5,000x max win on the final page.
A promotional spin can land the round like any other. See can you retrigger free spins for how extra spins in a round usually work, and the free spins round entry for the basics.
High volatility: what a short batch of spins looks like
Big Bass Splash is rated high volatility. Over a batch of 50 or 100 promotional spins, the usual pattern is modest returns with most of the value concentrated in the occasional free spins round. Many batches end below the average, and a few end well above it.
That shape is why no-wagering terms suit a game like this. A lucky batch is paid as cash rather than being exposed to further play. It also explains why a winnings cap, if an offer has one, removes more value here than on a steadier game. How caps are worded is covered in free spins max win.
Big Bass Splash RTP: 96.71% and the version check
The published Big Bass Splash RTP is 96.71%, the figure Reel Kingdom uses across several of its titles. Games can be supplied with alternative RTP settings, so the figure in the help screen of your casino's version is the one to trust. If it shows less, every value on this page falls slightly. Our RTP glossary entry explains the figure in more depth.
Big Bass Splash free spins no wagering: what cash winnings are worth
With no wagering, a 100-spin average of £9.67 is all withdrawable. With 10x wagering, the maximum allowed under the Commission's bonus code in the LCCP (opens in a new tab) since 19 January 2026, you'd need to stake £96.71 more. At a 3.29% edge that costs about £3.18 on average, leaving around £6.49.
In other words, wagering at the UK maximum removes about a third of the average value on this game, and on a high-volatility slot the balance may run out before the wagering ends. Our comparison of wager-free vs wagering spins has more examples.
Big Bass Splash free spins no deposit
Some UK-licensed casinos advertise Big Bass Splash free spins with no deposit, usually a small batch at 10p with a cap on winnings. None of our partners offers a no-deposit bonus. Twenty such spins are £2 of play, worth about £1.93 on average before any cap or wagering, and you'll still need to verify your identity first. Our page on free spins no deposit no wagering explains why those features rarely come together.
Big Bass Splash bonus play under UK rules
The UK version of Big Bass Splash follows Gambling Commission rules that may differ from versions shown elsewhere.
Slots at UK-licensed casinos are supplied without a feature-buy option, so the free spins round is only reached through play.
Since 31 October 2021 there has been no autoplay, turbo or slam-stop, and each spin lasts at least 2.5 seconds.
Since 9 April 2025, players aged 25 and over can stake up to £5 a spin; since 21 May 2025, 18 to 24-year-olds can stake up to £2.
Since 19 January 2026, wagering is capped at 10x the bonus and promotions mixing sports betting with casino spins are banned.

Frequently asked questions
How much are Big Bass Splash free spins worth?
At 10p each, Big Bass Splash free spins return about 9.67p on average, based on the 96.71% RTP. So 50 spins (£5) average about £4.84 and 100 spins (£10) about £9.67. As a high-volatility game, a single batch often returns less, with the occasional much larger result. Wagering or a winnings cap lowers the value further. The free spins value guide explains how to compare offers on different games.
How do you trigger free spins on Big Bass Splash?
You trigger the round by landing the required scatter symbols during an ordinary spin. The number of scatters, the number of free spins and any Splash-specific extras are listed in the game's help screen. Across the Big Bass series, the round's signature mechanic is a fisherman wild that collects cash values from fish symbols. Feature buys aren't offered on UK slots, so play is the only way in. The answer to whether free spins can trigger the bonus round covers promotional spins.
Are PlayOJO's free spins on Big Bass Splash?
No. PlayOJO's welcome offer is 80 free spins on Big Bass Bonanza, the original game in the series, not Big Bass Splash. The two share a 96.71% RTP and the same studio, but Splash has a higher 5,000x max win against 2,100x. The spins are 10p each (£8 of spins), need a first deposit of £10 or more and have no wagering. The offer is 18+, for new UK customers excluding Northern Ireland. Our PlayOJO casino bonus page has the full terms.
What is the Big Bass Splash RTP?
The published RTP is 96.71%, which gives a 3.29% house edge. Reel Kingdom uses the same figure on several titles, including Big Bass Bonanza. On a 10p spin that is an average return of about 9.67p over a very long run. Some games are supplied with alternative RTP settings, so check the help screen of your casino's version to be sure. Our page on UK RTP information rules explains what casinos must show.
Is Big Bass Splash better than Big Bass Bonanza for free spins?
Not in average value: both have a 96.71% RTP, so a 10p spin is worth the same on either. Splash's higher max win, 5,000x against 2,100x, means its results spread a little wider, with slightly more value tied up in rare big outcomes. For a promotional batch, the offer's terms decide far more than the choice between the two. Compare offers on spin count, stake, wagering and caps. See our Bigger Bass Bonanza free spins page for another series variant.
Can I get Big Bass Splash free spins with no deposit?
Some UK-licensed casinos occasionally offer them, but none of our partners has a no-deposit bonus. Expect a small number of 10p spins with a winnings cap and sometimes wagering, which can't exceed 10 times the bonus since 19 January 2026. On a high-volatility game, a cap removes more of the value than it would on a steadier slot. You'll still need to pass age and identity checks before playing. Our explainer on whether no deposit bonuses are a scam covers what to watch for.
Are Big Bass Splash free spins with no wagering worth more?
Yes. With no wagering, an average 100-spin result of £9.67 is cash. With 10x wagering, you'd stake another £96.71, which costs about £3.18 on average at a 3.29% edge and leaves around £6.49, roughly a third less. On a high-volatility game the bonus balance can also run out before wagering ends. All three of our partner spin offers pay winnings without wagering. For the current options, see which casino has no wagering.
What is the most a Big Bass Splash free spin can win?
The max win is 5,000 times the stake, so a 10p promotional spin can pay at most £500. Reaching it is rare and depends on the free spins round. If an offer caps withdrawable winnings below that, the cap is the limit that applies. Treat the maximum as a ceiling rather than a target, because the average value of a spin already includes these rare results. The free spins max win guide explains how to read a cap.
Can I use Coral or Ladbrokes free spins on Big Bass Splash?
Only if the promotion lists it, and we don't claim that it does. Coral's 100 spins and Ladbrokes' daily spins can be used only on the selected games each offer names, so check the promotion page before you deposit. Both offers are 18+, for new customers, pay winnings without wagering and exclude some payment methods, including PayPal and Skrill. Our answer to can I choose my free spins slot explains why the game is fixed.
Can I play Big Bass Splash for free before using spins?
Only after verifying your account. Since May 2019, UK-licensed casinos must check your age and identity before you play any game, including free-to-play demos, to keep under-18s out. Once verified, many casinos offer a demo that lets you read the help screen and see how the free spins round looks. Demo play still follows the UK design rules, with no autoplay or turbo. The age verification before play page explains the rule.
