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

In our view, the best modern variant of the Big Bass franchise — released in March 2023 by Reel Kingdom, it introduces the game-changing Hold & Spinner mechanic. The max win jumps to 10,000x (versus 2,100x on the original Bonanza and 5,000x on Splash), the Multiplier Trail climbs up to x10, and the Ante Bet adds +50% stake to boost free spin frequency. Free spin hit frequency sits at 1 in 233 spins without Ante. Bonus buy available at 100x stake. The most complete pick for anyone chasing the franchise's top potential.

About Big Bass Bonanza Hold & Spinner

Released in March 2023, Big Bass Bonanza Hold & Spinner is a major evolution of the franchise — Reel Kingdom built in the Hold & Spinner mechanic (similar to classic Hold & Win but adapted to the fishing theme). The grid stays at 5x3 on 10 paylines for Big Bass consistency, but the big new addition is the Multiplier Trail, which can reach x10, plus the Ante Bet (+50% stake to double the chance of triggering free spins). Max win sits at 10,000x — the highest across the whole classic franchise. Natural free spin hit frequency: 1 in 233 spins (versus 1 in 113 on the original Bonanza). Bonus buy available at 100x stake.

❓Big Bass Hold & Spinner FAQ

What is the RTP of Big Bass Hold & Spinner?▾

Official RTP: 96.

07% (high version). Reduced versions exist (94. 07% / 95. 08%). Check via the in-game 'i' button.

How does Hold & Spinner work?▾

When the bonus triggers, the grid partially clears and you get 3 spins.

Every coin (Cash Fish) that lands sticks to its position and resets the spin count to 3. The bonus ends after 3 spins with no new coin. The fuller the grid gets, the more multipliers and values stack up.

Hold & Spinner vs Big Bass Splash — which one to pick?▾

Hold & Spinner offers a 10,000x max win (vs 5,000x on Splash), a unique Hold & Spinner mechanic, and the Multiplier Trail.

Splash is simpler, with direct x2/x3/x10 multipliers. Hold & Spinner is more modern and more generous — our favourite of the classic franchise.

Is the Ante Bet worth it?▾

Yes, over the long run.

The +50% stake Ante Bet almost doubles the natural free spin trigger frequency. RTP stays the same (96. 07%), but you hit bonus more often, meaning lower perceived variance. Recommended on this variant.

Is the 100x bonus buy profitable?▾

Bonus buy RTP matches the base game: 96.

07%. Across 50 tested buys, the average return was around 92x with a few hits over 1,000x. Good accessibility too (100x = €10 for a €0. 10 stake).
