Big Bass Boom

What Big Bass Boom has actually done in our bonus hunts

We have opened Big Bass Boom 8 times across 8 separate bonus hunts between 12 Jul 2026 and 2 Aug 2026 and recorded every result. Across those 8 opens the median result was 50.4× the bet, against 50× for every slot in our recorded dataset. The biggest single result we have recorded on it is 135.2×. 1 of those 8 opens was 100× or better. 8 opens is a small sample and describes only these recorded sessions — it is not this slot's RTP and it does not predict what your next bonus will do.

Big Bass Boom is Pragmatic Play's latest addition to its sprawling fishing-themed franchise, built on the series' familiar 5-reel, 3-row structure with 10 fixed paylines. It carries a strong 97.07% RTP, a high 5-out-of-5 volatility rating, and a maximum win of 5,000x the stake.

What to Expect from the Setup

Details on Big Bass Boom's specific bonus mechanics haven't been fully documented yet, but the numbers alone tell a fairly consistent story for anyone familiar with the series. A 97.07% RTP sits comfortably above the market average and above several of this franchise's own entries, making it one of the more player-friendly return figures in the current Big Bass lineup. Given the name, expect the usual angling iconography — a fisherman character, tackle-box symbols, and the series' trademark Money symbol collection mechanic — likely wrapped in a slightly punchier, more explosive visual theme than some of the calmer entries in the range.

RTP and Betting Range

Stakes run from 10p up to £250 a spin, keeping the game accessible to a wide range of bankrolls. As with virtually every Big Bass release, an ante bet option is likely available for players wanting improved odds of triggering the bonus round in exchange for a higher stake, though exact terms should always be confirmed on the in-game paytable before playing.

High Volatility and What It Means

A 5-out-of-5 volatility rating puts Big Bass Boom among the more aggressive entries in the series. Expect longer stretches between significant wins, offset by the potential for the free spins round — almost certainly built around collecting Money symbol values via a wild fisherman character, in keeping with the franchise's long-standing formula — to deliver a meaningfully larger payout when it does land.

Max Win Potential

The 5,000x ceiling is right in line with a large portion of the Big Bass catalogue, a solid if unspectacular top prize compared with some of the series' higher-variance Megaways-style entries that push into five-figure territory.

Final Thoughts

Big Bass Boom looks, on paper, like another confident entry in an enormous and still-growing franchise, offering an above-average RTP wrapped in the high-volatility, Money-symbol-driven gameplay the series is known for. Fans of the format who prioritise return over sheer novelty should find plenty to like here. The best way to judge whether the boom lives up to the name is to spin it up on the free demo at johnessyslots before deciding whether it earns a spot in your real-money rotation.
