Big Bass Bonanza 1000 is the supercharged follow-up to the original fishing slot from Reel Kingdom and Pragmatic Play. It keeps the same five reels, three rows and ten fixed paylines, and it keeps the free spins round where a fisherman wild collects fish values. What changes is the ceiling: money symbols can now reach 1,000x your stake and the game advertises a maximum win of 20,000x, almost ten times the 2,100x of the original.
It launched in April 2025. This review looks at which numbers are officially stated, which are third-party estimates, what the hook feature adds, and how the bigger top prize changes the experience at realistic UK stakes.

How to play and stakes
Set your total stake, spin and match symbols from the left across adjacent reels. The ten lines are fixed, so there is no payline choice to make. Wins pay left to right and wins on different lines are added up.
UK licensed casinos cap slot stakes at £2 for players aged 18 to 24 and £5 for those aged 25 and over, and individual casinos can set lower limits. The minimum stake is normally £0.10. Pragmatic Play does not list a stake range on its public game page, so confirm the range in the game information screen at your casino.
The 20,000x figure sounds enormous, but it is worth translating into pounds at UK stakes:
| UK stake per spin | Max win at 20,000x |
|---|---|
| £0.10 | £2,000 |
| £1 | £20,000 |
| £2 | £40,000 |
| £5 | £100,000 |
Reviewers mention an Ante Bet and bonus buy options in some markets. Availability depends on the casino and jurisdiction, and neither is something to count on at a UK site, so none of our figures assume them.
RTP: which version?
Pragmatic Play lists an RTP of 96.51%, which is 0.2 percentage points below the original game’s 96.71%. It is the only version we found stated by the provider. As with most Pragmatic Play slots, operators can choose a different setting, so a UK casino may run a different RTP from the headline. Check the information screen at your own casino before you start and trust that figure over any review, ours included.
Volatility
OLBG’s series guide rates Big Bass Bonanza 1000 as very high volatility, and review sites broadly agree it sits at the top end. The reasoning is straightforward: the hit frequency is similar to the original (see below), but the top prizes are far larger and far rarer. You are more likely to experience long quiet spells and bonus rounds that return little, with the odd round that pays a lot.
Max win
Pragmatic Play states wins of up to 20,000x. One third-party reviewer, GamblingZone, calculates the chance of reaching that maximum at roughly 1 in 6.37 million spins. That is not a provider figure, so treat it as a rough guide. Either way, hitting the cap is vanishingly rare. A more useful way to think about it is that the high ceiling comes from the combination of 1,000x money symbols, multiple wilds and the multiplier ladder all lining up in one round.
Features and bonus rounds
Free spins and the hook
Three, four or five scatters award 10, 15 or 20 free spins. If only two scatters land in the base game, a third can be reeled in at random. Reviewers describe two versions of this: existing scatters nudging down while other reels respin, or a hook pulling in an extra scatter. Pragmatic Play’s page confirms the idea but not the exact variants, so treat the detail as reported.
Money symbols and collector wilds
During free spins the fisherman wild collects every visible money symbol. Values run up to 1,000x your total stake, and the provider adds that wilds and money symbols can randomly appear on the grid after each free spin.
Retrigger ladder
Every fourth wild collected retriggers the feature and adds 10 spins. The multiplier on collected money rises to 2x on the first retrigger, 3x on the second and 10x on the third, and that third retrigger is the last.
The structure is the same as the original, but the money symbols are bigger, which is why a single good screen can be worth far more.
Symbols and paytable
Pragmatic Play does not publish a paytable on its public page. Third-party reviewers report that the top line symbol, the float, pays 200x for five of a kind, in line with the original game. The remaining line symbols follow the same fishing equipment and card-royal pattern, with the real action reserved for money symbols and the scatter. Check the paytable inside your casino’s game for exact values.
Win rate and hit frequency
Pragmatic Play does not publish hit frequency or bonus frequency for this game. The named independent source we use is OLBG, whose Big Bass guide lists a hit frequency of 1 in 7.58 spins (about 13%) and a free spins trigger roughly once every 116 spins. These are the same figures used in SlotPal’s hit rates guide for Big Bass and Eye of Horus.
That is almost identical to the original game’s listing of about 1 in 7.7 and 1 in 113. In other words, the extra potential seems to come from rarer, bigger top-end values rather than from more frequent bonuses. It is an inference from the published numbers, not an official statement.
Is Big Bass Bonanza 1000 enjoyable?
SlotPal’s verdict is based on the game’s mechanics, the provider’s stated rules and independent data, not on a long personal play session.
The appeal is obvious: the familiar bonus is the same, but the possible payoffs are now dramatic. That raises the tension on every free spin, particularly once multipliers start to climb. The cost is a slower, more demanding base game. Because the hit frequency is no better than the original and the volatility is higher, you will spend most of your time waiting for the feature, and many features will be disappointing.
Verdict: an exciting upgrade for players who want a big ceiling and can tolerate heavy swings. If you prefer steadier sessions, the original or a lower-volatility entry in the series is the better fit.

Frequently asked questions
What is the RTP of Big Bass Bonanza 1000?
Pragmatic Play lists 96.51%. Casinos can use other settings, so check the information screen in the game you open.
What is the maximum win?
Pragmatic Play states up to 20,000x your total stake. At a UK £5 stake that equates to £100,000, although the chance of reaching it is extremely small.
How many free spins can I get?
Three, four or five scatters award 10, 15 or 20 free spins. Each retrigger adds 10 more, and the feature can retrigger up to three times.
How do the multipliers work?
After every fourth wild collected, the feature retriggers. The multiplier on money collection is 2x on the first retrigger, 3x on the second and 10x on the third.
What are the money symbol values?
They can reach 1,000x your total stake according to Pragmatic Play. The wild collects all visible values during free spins.
What is the hook feature?
If two scatters land, a third can be randomly reeled in to start the bonus. Reviewers describe more than one way this can happen.
How often does the bonus trigger?
Pragmatic Play does not publish this. OLBG lists about 1 in 116 spins, which is a third-party estimate.
What are the UK stake limits?
UK casinos cap slot stakes at £2 for ages 18 to 24 and £5 for ages 25 and over. The minimum is normally £0.10.
Is it more volatile than the original Big Bass Bonanza?
Yes. OLBG rates it very high, against medium-high for the original, mainly because the top prizes are much larger and rarer.
Is there a bonus buy in the UK?
Reviewers mention buy options in some markets, but you should not expect one at a UK casino. Check the menu in the game you open.
Can I try it for free?
Yes, the demo above uses play money. It runs on a global server and shows dollars, so values and features may differ slightly from a UK pound version.
