How the Big Bass Splash features work
The base game is a reel slot where you land matching symbols to win. The part most people play for is the bonus round, and Pragmatic Play describes it like this:
- Trigger: land 3, 4 or 5 scatter symbols to start 10, 15 or 20 free spins.
- Money symbols and wilds: during free spins, fish “money symbols” carry cash values of up to 5,000x. When a wild (the fisherman) lands alongside them, it collects those values.
- Retriggers and multipliers: every fourth wild collected retriggers the feature with 10 more free spins, and applies a 2x multiplier to collected values on the first retrigger, 3x on the second and 10x on the third.
- Modifiers: before free spins begin, up to five modifiers can be added at random, including extra money symbols, extra wilds and extra spins.
Big Bass Splash max win
Pragmatic Play’s game page doesn’t state a maximum win for Big Bass Splash, so we don’t quote one. The 5,000x figure on the page is the top value of a single money symbol in the bonus, not the game’s overall cap. If you want the exact figure, check the paytable or game rules inside the game at your casino.
Big Bass Splash stake limits in the UK
Whatever the game’s own settings, UK-licensed casinos must cap online slot stakes at £5 per spin if you’re 25 or over and £2 per spin if you’re 18–24. The £5 limit came in on 9 April 2025 and the £2 limit on 21 May 2025. The casino has to check your age to apply the right limit, so the maximum you see in the game may differ from a friend’s.
Lower stakes don’t change the RTP, but they do change how long a budget lasts. On average, a 96% RTP game returns about £96 for every £100 staked over a very long run, so £100 of total stakes would be expected to cost about £4, but any one session can be far better or far worse than that.
Casino offers with Big Bass Splash spins
Two of the casino offers we’ve verified give spins on Big Bass Splash:
- Midnite: new customers 18+, sign up with code BETGETCASINO, deposit at least £20 and wager £20 or more on eligible games within 14 days. Reward: 100 free spins on Big Bass Splash at 10p each (£10 total value), which expire 7 days after they’re credited. Free stake isn’t returned with winnings. Midnite’s offer page doesn’t state wagering on spin winnings.
- Unibet: new customers 18+ in Great Britain. Opt in at registration, deposit £30+ by debit card or instant bank transfer, and stake £30 on slots within 7 days. Reward: 300 free spins at 10p on Big Bass Splash, to be used within 48 hours. Winnings must be wagered 10x on slots within 30 days. Credit cards, Apple Pay, PayPal, Paysafecard, Skrill and Neteller don’t qualify.
Both deposits are your own money and must be staked first. Only claim if you’d have spent that much anyway.
Responsible play on Big Bass Splash
Big Bass Splash concentrates its value in the bonus round, so long gaps between features are normal. Don’t raise your stake to “reach” the bonus. Treat any spend as the price of entertainment, not an investment. Spins are fast, so check the in-game clock or set a reality check. If a session isn’t fun any more, stop; there’s no “due” win.

UK rules that apply
- Slot stake limits. The most you can stake per online slot spin is £5 if you’re 25 or over and £2 if you’re 18–24 (Gambling Commission). These limits apply to online slots, not table games.

- No credit cards. Since 14 April 2020, licensed operators can’t accept credit card payments for gambling, including through e-wallets funded by a credit card.
Staying in control
Set a deposit limit before you play, decide in advance what you can afford to lose, and use reality checks and time-outs. Never chase losses. If you want a break from all UK-licensed gambling sites at once, GamStop is free and lets you self-exclude for 6 months, 1 year or 5 years. The National Gambling Helpline (0808 8020 133) is free, confidential and open 24 hours. More help: responsible gambling.
