    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Released in September 2021, Bigger Bass Bonanza is the 5×4 evolution of the best-selling Big Bass Bonanza. Top-tier 96.71% RTP, 4,000x max win, and a wider format with 12 paylines instead of 10 on the original.

    Strengths

    • +Generous 5×4 format (12 paylines vs 10 on the original)
    • +96.71% RTP — top tier for Pragmatic
    • +Progressive x10 free spin multipliers
    • +Money symbols worth x1-x100 stake
    • +100x bonus buy available
    • +More accessible variance than Big Bass Splash

    To consider

    • 4,000x max win is modest next to Splash's 5,000x and Hold & Spinner's 10,000x
    • Big Bass series saturation (10+ variants)
    • Bonus buy unavailable in the UK
    • Fairly basic mechanics compared to newer variants

    About Bigger Bass Bonanza

    Released in September 2021 by Reel Kingdom (Pragmatic Play's in-house fishing-themed studio), Bigger Bass Bonanza is the direct — and most popular — follow-up to the original Big Bass Bonanza (2020). Rather than chasing an ever-higher max win the way Big Bass Splash (5,000x) or Big Bass Hold & Spinner (10,000x) did, Bigger Bass opted for a wider grid format: 5×4 instead of the original's 5×3, with 12 paylines instead of 10, giving more opportunities for regular wins while keeping the variance approachable.

    The format is a 5×4 grid on 12 paylines with a 96.71% RTP in the official high version — top tier (double-check in-game, as degraded 95.67% and 94.53% configurations exist at some casinos). Volatility is high, but lower than Big Bass Splash. The max win is 4,000x your stake — modest next to the series' more extreme variants, but reachable through regular hits.

    Signature mechanics: Money Symbols collect (Cash Fish symbols worth x1 to x100 stake that appear on the grid during free spins and are automatically gathered by the Fisherman Wild), and free spins with progressive multipliers (3 scatters = 10 spins, 4 = 15 spins, 5 = 20 spins). The multiplier climbs with every Fisherman wild collected: x1 (base) → x2 (4 wilds collected) → x3 (8 wilds) → x10 (12+ wilds).

    The bonus round triggers with 3+ Fisherman scatters (roughly a 1-in-180 chance per spin in the base game — slightly more frequent than the original Big Bass Bonanza's 1-in-200). Bonus buy is available at 100x stake (unavailable in the UK) — a major difference from the original Big Bass Bonanza, which has no bonus buy at all. It's the deciding factor for players who'd rather skip the base-game grind.

    Availability in France: Bigger Bass Bonanza is widely distributed — available at virtually every casino that carries Pragmatic Play, from French ANJ-regulated sites to crypto casinos in BCE's French top rankings (SpinAura, BetRiviera, Prestige, MonacoJack). It's one of the most accessible Big Bass follow-ups internationally. For fishing-franchise fans after a wider format with a bonus buy and moderate variance, Bigger Bass Bonanza is the ideal middle ground — between the original Big Bass Bonanza (no bonus buy) and Big Bass Splash (higher variance, 5,000x max).

    Key mechanics

    • 5×4 grid on 12 paylines (vs 5×3 / 10 paylines on the original)
    • 96.71% RTP in the official high version (top tier for Pragmatic)
    • Money Symbols: Cash Fish worth x1 to x100 stake
    • Fisherman Wild automatically collects during free spins
    • Progressive multipliers: x1 → x2 (4 wilds) → x3 (8 wilds) → x10 (12+ wilds)
    • Free spins: 3 scatters = 10 spins, 4 = 15, 5 = 20
    • Natural trigger rate ~1 in 180 spins (more frequent than the original's 1 in 200)
    • 100x stake bonus buy available (a difference from the original)
    • Reel Kingdom's Big Bass fishing universe
    • High volatility, but more approachable than Splash or Hold & Spinner
    💰 Bonus Buy: 100x stake (banned in UK)

    Bigger Bass Bonanza FAQ

    What's the RTP on Bigger Bass Bonanza?

    The official RTP is 96.

    71% in the high version — top tier for Pragmatic Play. Note: degraded 95. 67% and 94. 53% versions exist at some casinos. Always check via the in-game "i" button before playing seriously.

    What's the difference between Bigger Bass Bonanza and the original Big Bass Bonanza?

    Big Bass Bonanza (2020): 5×3 on 10 paylines, 2,100x max win, NO bonus buy.

    Bigger Bass Bonanza (2021): 5×4 on 12 paylines, 4,000x max win, 100x bonus buy available. Bigger Bass means a wider format, a bonus buy option, and double the max win. Mechanics are otherwise very similar.

    Bigger Bass Bonanza vs Big Bass Splash?

    Bigger Bass Bonanza (2021): 5×4 format, 4,000x max win, moderate variance, 100x bonus buy.

    Big Bass Splash (2022): 5×3 format, 5,000x max win, higher variance, 100x bonus buy, Western-themed multipliers. Bigger Bass gives steadier sessions; Splash offers roughly 25% more big-win potential.

    What's the max win on Bigger Bass Bonanza?

    4,000x your stake — reached through an exceptional free spins round with 12+ Fisherman wilds collected (x10 multiplier) plus several x100-stake Cash Fish landing in the right spots.

    Probability of hitting the max is roughly 1 in 40,000 spins. Wins of 1,000-2,000x are far more common.

    Should you buy the bonus at 100x stake?

    If you've got the bankroll and want to skip the base-game grind (1-in-180 natural trigger), yes.

    Bonus buy RTP is generally higher than effective short-term base-game RTP (96. 71% vs roughly 93-95% effective). 100x stake means €10 for a €0. 10 minimum bet. Across 100 buys, expected return is roughly 85-90x, but variance remains high.

    Is Bigger Bass Bonanza available in France?

    Yes — widely distributed on French ANJ-regulated casinos as well as crypto casinos in BCE's French top rankings (SpinAura, BetRiviera, Prestige, MonacoJack).

    One of the most internationally accessible Big Bass follow-ups.

    How often do the free spins trigger?

    The natural trigger rate is roughly 1 in 180 spins in the base game (slightly more frequent than the original Big Bass Bonanza's 1 in 200).

    Across 1,000 spins, expect around 5-6 natural bonus rounds. Buying the bonus at 100x stake gives direct access without the grind.

    Who is Bigger Bass Bonanza for?

    Fans of the Big Bass franchise after a wider 5×4 format with a bonus buy and moderate variance.

    Players who want the Reel Kingdom fishing experience without Big Bass Splash's brutal swings. Skip it if you want the series' highest max win — go for Big Bass Hold & Spinner (10,000x) or Big Bass Trophy Catch instead.
