Free spins on Big Bass Bonanza are available to new UK customers at PlayOJO: make a first deposit of at least £10 and you get 80 spins on the game at 10p each, with winnings paid as cash and no wagering. 18+, Northern Ireland excluded, terms apply. Below: how to claim, what the spins are worth and how the game’s own feature works.
PlayOJO gives 80 spins on Big Bass Bonanza at 10p after a first deposit of £10 or more, with no wagering.
Face value is £8; at the developer’s 96.71% RTP, 80 spins return about £7.74 on average.
A promotional spin can trigger the game’s own 10, 15 or 20 free spins, where the fisherman collects fish cash values.
At 10p, the 2,100x max win is £210 per spin; most batches finish far below that.

PlayOJO is run by Skill On Net Limited, which holds UK Gambling Commission account 39326. We have not verified PlayOJO’s payment methods or payout times, so check the cashier for which deposit options qualify. The PlayOJO free spins page covers the site’s spin offers more broadly.

What 80 spins at 10p are worth
The headline maths is simple. Eighty spins at 10p is £8 of play. At the developer’s published RTP of 96.71%, the long-run average return on that £8 is about £7.74. Because there is no wagering, the expected value of the spins is close to that figure, which is unusual: on a wagered offer, the playthrough would take a further slice.

Big Bass Bonanza is high volatility, so treat £7.74 as a long-run figure rather than a forecast. Many batches of 80 spins return less than £5, and a few return much more because the feature landed with good fish values. The RTP your spins run at is the one PlayOJO uses; the game’s info screen shows it. See how to work out free spins value for the method.
How Big Bass Bonanza’s own free spins round works
The game, developed by Reel Kingdom and distributed by Pragmatic Play, has its own free spins feature, and any of your 80 promotional spins can trigger it. Three, four or five scatter symbols award 10, 15 or 20 free spins at the same 10p stake.
During the round, fish symbols carry cash values, and the fisherman wild collects every fish value on the screen when he lands. Every fourth fisherman collected retriggers the round with ten more spins, and the values he collects are multiplied: 2x on the first retrigger, 3x on the second and 10x on the third. That progression is where the game’s larger wins come from, and it is also why most features pay modestly: you need several fishermen to start climbing it.
The full Big Bass Bonanza review covers the paytable and symbols. The cash collect entry explains the collection mechanic that the series popularised.
What most of your 80 spins will look like
Outside the feature, Big Bass Bonanza plays like a classic ten-line slot on five reels and three rows. Fish symbols can appear in the base game, but they are only collected during free spins, so in the base game they do nothing. Line wins at 10p are mostly a few pence to a few pounds, and runs of dead spins are normal for a game with this volatility.
Each spin takes at least 2.5 seconds under UK rules, so 80 spins take a little over three minutes of pure spin time. There is no autoplay, so you press for each one, and the screen shows your net position throughout.
No wagering and what happens to your winnings
Because the spins carry no wagering, the winnings join your cash balance straight away and can be withdrawn under PlayOJO’s normal withdrawal rules, once your account is verified. Your £10 qualifying deposit is also real money. PlayOJO also advertises OJOplus, a money-back feature on games played; check its terms for how it applies to your play.
Coming from the Big Bass spins, it is easy to keep playing the same game with your deposit. Decide before you start whether the £10 is for play or will be withdrawn.

Frequently asked questions
Which UK casino gives free spins on Big Bass Bonanza?
PlayOJO gives new UK customers 80 spins on Big Bass Bonanza when they make a first deposit of at least £10. The spins are worth 10p each and carry no wagering, so winnings go straight to your cash balance. The offer is for players aged 18 and over and excludes Northern Ireland. Other casinos run Big Bass offers from time to time, but this is the one we can verify among our partners. The PlayOJO welcome offer page goes through the terms in full.
Do PlayOJO’s Big Bass Bonanza spins have wagering?
No, the 80 spins have no wagering, so anything you win from them is paid as cash. That is unusual among UK welcome offers, many of which still convert spin winnings into bonus funds with a playthrough of up to 10x. With no wagering, you can withdraw the winnings once your account is verified, under PlayOJO’s normal rules, without needing to stake anything further. The no wagering slot sites page explains how these offers differ from wagered ones.
How much are 80 free spins on Big Bass Bonanza worth?
The 80 spins have a face value of £8, because each one is worth 10p. Using the developer’s published 96.71% RTP, the average return is about £7.74, and with no wagering that is close to the real expected value. The game is high volatility, so most batches finish below the average and a few finish well above it. The most a single 10p spin can pay is £210, at the 2,100x max win. The 80 free spins page compares other offers of this size.
How do you trigger free spins on Big Bass Bonanza?
Land three, four or five scatter symbols in one spin to receive 10, 15 or 20 free spins. During the round, fish symbols show cash values and the fisherman wild collects them all when he lands. Each fourth fisherman retriggers ten more spins and raises a multiplier on collected values, first to 2x, then 3x and finally 10x. Feature buys are not available in Great Britain, so scatters are the only way in. The how slot features trigger guide explains the odds behind scatters.
Can PlayOJO’s spins trigger the Big Bass Bonanza feature?
Yes, each promotional spin is a normal spin at 10p, so three or more scatters trigger the feature exactly as they would on a paid spin. The feature’s spins are played at the same 10p value and do not use up your remaining promotional spins. Anything the feature pays counts as winnings from that spin and, under PlayOJO’s no-wagering terms, is paid in cash. This is the main route to a larger result from the batch. The what is a slot bonus round page explains features in general.
Can I claim PlayOJO’s Big Bass spins in Northern Ireland?
No, the published terms exclude Northern Ireland, so the offer is only for new customers in Great Britain. Gambling in Northern Ireland is regulated separately from Great Britain, and some operators exclude it from promotions. You may still be able to open an account and play depending on the site’s terms, but the 80 spins will not be credited. Coral and Ladbrokes publish their own eligibility rules, so check those too. The can you play slots in Northern Ireland page explains the position.
What payment methods qualify for PlayOJO’s free spins?
We have not verified PlayOJO’s accepted payment methods, so check the cashier and the full offer terms before you deposit. The offer needs a first deposit of at least £10, and credit cards cannot be used to gamble in Great Britain, including through e-wallets funded by a credit card. If a method is excluded from the welcome offer, the spins may not be credited, and that cannot usually be fixed afterwards. The slot site payment methods guide explains how different methods work at UK casinos.
Is Big Bass Bonanza a good slot for free spins?
Big Bass Bonanza works well for spins because it has a high published RTP of 96.71% and its own feature that a promotional spin can trigger. The trade-off is high volatility: a batch often returns little, while a good feature with several fishermen can pay far more than the spins cost. The maximum is 2,100x, lower than many newer slots, which keeps the top end modest. For steadier results, a low-volatility game behaves differently. The Fishin' Frenzy vs Big Bass Bonanza page compares two fishing favourites.
Are there Big Bass Bonanza free spins with no deposit?
None of our partners gives Big Bass Bonanza spins without a deposit. PlayOJO’s offer needs a first deposit of £10, though the spins carry no wagering, which often makes them worth more in practice than a no-deposit batch with a low win cap. If you see a no-deposit Big Bass offer, check the operator’s UK licence, the maximum you can win and whether card details are required. Since January 2026, any wagering on it cannot exceed 10x. The free spins no deposit page explains the alternatives.
