Big Bass Surf’s Up (Jackpot Bonanza) Slot Review: 92% RTP, Surfer Wilds and Local Jackpots

2 October 2026 · 8 min read

Big Bass Surf’s Up is a surf-themed entry in Pragmatic Play’s Big Bass family. The version covered here is the jackpot edition, listed in full as Big Bass Surf’s Up (Big Bass Jackpot Bonanza) and released on 26 November 2025 as one of five games in a jackpot network. The base layout is the familiar five reels, three rows and ten paylines, and the bonus is a free spins round where surfer wilds collect fish money values.

What sets this version apart is a randomly triggered jackpot bonus with four local progressive jackpots. This review explains how the game works, why published RTP figures disagree, and what we could not confirm from the provider’s own pages.

How to play and stakes

Pick your total stake and spin. Ten fixed lines pay left to right across adjacent reels. OLBG lists a UK stake range of 10p to £5, which fits the regulator’s caps: £2 for players aged 18 to 24 and £5 for those aged 25 and over. Individual casinos may apply tighter limits.

Some trackers list a much higher top stake of 375 for unrestricted markets. That does not apply in the UK.

UK stake per spin Max win at 5,000x (excluding jackpots)
£0.10 £500
£1 £5,000
£2 £10,000
£5 £25,000

Reviewers also mention a bonus bet and a buy feature in some markets. Availability depends on the casino and jurisdiction, so do not assume either is offered at a UK site.

RTP: why the figures conflict

OLBG and SlotCatalog both list this game at 92%. That is noticeably lower than the 96.5% to 96.7% typical for the rest of the Big Bass range, and it is the figure shared by the other games in the Jackpot Bonanza network. One lesser-known site lists 96.48% with a 12,500x max win, which matches no other source, so we have not used it.

We could not locate a Pragmatic Play game page for this title, so none of these figures could be checked against the provider. It is plausible that the 92% reflects the base game and that the progressive jackpot contribution sits on top of it, but we have not found a source that says so, so treat that as a possibility, not a fact. Because UK casinos can run different RTP settings, check the information screen in the game itself before you play.

Volatility

OLBG rates the game as very high volatility with a 3 out of 5 overall rating, and SlotCatalog calls it high. Both fit the Big Bass pattern: the base game pays small amounts, and the free spins and the jackpot bonus produce the large results. Plan for long quiet spells.

Max win and jackpots

The standard maximum win is 5,000x your stake, and OLBG states that this figure excludes the progressive jackpots. The jackpot bonus is a separate, randomly triggered feature. Once it starts you pick items on a bonus screen to reveal matching Minor, Major, Mega or Grand symbols, and the three that match decide which jackpot you win.

Jackpot amounts are local to the casino or group, so they differ from site to site. OLBG notes that the Grand jackpot can be worth up to £10 million, though that is an upper figure from a reviewer and not a promise about any particular site. The odds of triggering the feature are not published in the sources we found.

Features and bonus rounds

Free spins

The main feature is a free spins round that starts with up to 20 spins. Surfer wilds appear during the round and collect all visible fish money symbols. OLBG lists fish values of up to 5,000x your stake.

Retriggers and multipliers

Every fourth surfer wild collected awards 10 more free spins and increases the fish money multiplier to 2x, then 3x and finally 10x. This is the same ladder used throughout the family.

Jackpot bonus

A randomly triggered bonus can award one of four progressive jackpots through the pick-and-match screen described above.

Other features reviewers mention

SlotCatalog also lists mystery symbols, random multipliers and a bonus bet. We could not confirm the details from the provider, so we do not rely on them here.

Symbols and paytable

We could not find a published paytable for this game. The fish are money symbols, the surfer is the wild during free spins and a scatter triggers the bonus. Check the in-game paytable at your casino for exact line payouts.

Win rate and hit frequency

No hit frequency is officially published, and we did not find a named independent source that measures one for this specific game. OLBG lists a 12.67% hit frequency for the sister game Big Bass Hold & Spinner (Big Bass Jackpot Bonanza), but that is a different game, so we do not apply it here. SlotPal’s hit rates guide for Big Bass and Eye of Horus does not cover this release.

In short, there is no verified win rate or bonus frequency for Surf’s Up. Any figure you see elsewhere without a named source should be treated as a guess.

Is Big Bass Surf’s Up enjoyable?

SlotPal’s verdict is based on the game’s mechanics and the sources we could check, not on a long personal play session, and it is limited by the information gaps above.

The attraction is the combination: the proven Big Bass free spins, plus a jackpot chance that most of the series lacks. The surf theme is a cheerful change. The cost is a lower listed RTP, high volatility and a jackpot that is rarely triggered. If you play for the jackpot, remember that the odds are not published.

Verdict: a reasonable choice for series fans who want a progressive jackpot chance, but the 92% figure, the missing odds and the lack of official information make it harder to recommend than the standard Big Bass games. Check the RTP in your own casino before playing.
