Big Bass Bonanza Hold & Spinner launched in March 2023 from Reel Kingdom — in our view, it's the best modern variant of the Big Bass franchise. Reel Kingdom built in the signature Hold & Spinner mechanic (similar to the classic Hold & Win but adapted to the fishing theme), added a Multiplier Trail up to x10, an Ante Bet (+50% stake to boost FS frequency), and above all pushed the max win up to 10,000x — the highest of the entire classic franchise (vs. 2,100x on the original Bonanza, 5,000x on Splash).
This is a full Big Bass Hold & Spinner review: breaking down the unique Hold & Spinner mechanic, whether the Ante Bet is worth it, a comparison with the other Big Bass titles, the official RTP (96.07% in the high version), and where to play in 2026.
TL;DR — Big Bass Hold & Spinner in 4 points
- Reel Kingdom slot, March 2023, a 5x3 grid over 10 paylines (the Big Bass signature format preserved). RTP 96.07% in the high version (degraded versions of 94.07% / 95.08% are possible).
- High volatility (5/5), max win 10,000x the stake — the highest of the entire classic franchise.
- A unique Hold & Spinner mechanic within the franchise + a Multiplier Trail up to x10 + an Ante Bet (+50% stake) to boost FS frequency.
- 100x-stake bonus buy (non-UK). FS hit frequency: 1/233 spins. Max-win hit rate: 1/2,750,653 spins. Top 5 spots: SpinAura, BetRiviera, Millioner, BetMac.
Why Hold & Spinner is our favorite Big Bass title
Three years after the original Bonanza, Reel Kingdom built a variant that genuinely pushes the franchise forward:
- Hold & Spinner mechanic: a genuinely new mechanic within the series (vs. classic FS on Bonanza/Splash)
- 10,000x max win: the biggest of the classic franchise (vs. 2,100x on Bonanza, 5,000x on Splash)
- Multiplier Trail x10: a progressive multiplier specific to Hold & Spinner
- Ante Bet: a +50% stake option that nearly doubles the frequency of natural FS
- 100x-stake bonus buy: carried over from Splash
It's the Big Bass title veterans recommend to intermediate/advanced players. For beginners, Splash remains more approachable (slightly lower volatility).
The mechanics in detail
Base game (5x3 over 10 paylines + Ante Bet)
A classic 5x3 grid over 10 paylines (preserved across the entire franchise for consistency). The Ante Bet is the base game's main option:
- Standard stake: 100% normal, standard natural FS frequency
- Ante Bet activated: +50% stake (a €0.10 stake becomes €0.15), natural FS frequency nearly doubled
The Ante Bet does NOT change the RTP (still 96.07%) — it only shifts the payout distribution to favor bonus triggers. Recommended unless your bankroll is very tight.
Triggering Free Spins / Hold & Spinner
3+ scatters on reels 1, 3, and 5:
- 3 scatters = 10 free spins
- 4 scatters = 12 free spins
- 5 scatters = 15 free spins
Official hit frequency (per SlotCatalog): 1 trigger every 233 spins without Ante Bet, roughly 1/120 with it.
The Hold & Spinner mechanic (the heart of the game)
During free spins:
- Cash Fish symbols appear normally
- When a Fisherman Wild collects them, they stay stuck to their position on the grid (Hold & Spinner)
- Stuck Cash Fish accumulate spin after spin
- At the end of the bonus, every accumulated Cash Fish value is summed and multiplied by the Multiplier Trail
This is a different mechanic from the classic Big Bass titles, where Cash Fish were consumed immediately. Here they accumulate — hence the name "Hold & Spinner."
Multiplier Trail (x1 → x10)
During FS, a multiplier trail progresses at the top of the screen:
- 0-3 wilds collected: multiplier x1
- 4-7 wilds: multiplier x2
- 8-11 wilds: multiplier x4
- 12+ wilds: multiplier x10
The final multiplier applies to the total sum of accumulated Cash Fish at the end of the bonus. The more wilds you collect, the more likely the big win.
100x-stake bonus buy
Skip straight to 10 free spins for 100x your stake (€10 for a €0.10 stake). Bonus buy RTP is identical (96.07%). Not available in the UK.
RTP — 96.07% (degraded versions possible)
| Version | RTP | Recommendation |
|---|---|---|
| High | 96.07% 🏆 | Play this if it's available |
| Standard | 95.08% | Acceptable |
| Low | 94.07% | Avoid if possible |
Note: RTP is slightly lower than the original Bonanza (96.71%) and Splash (96.71%) because the Hold & Spinner mechanic allows for bigger hits — Pragmatic compensates by lowering the RTP by 0.6 points.

Strategies by budget
Small budget (< €200)
Bonus buy at 100x stake = €10 (€0.10 stake). You can run 20 buys with €200. Turn on Ante Bet from the start to boost your odds of natural triggers plus buys. RTP 96.07% = an average return of roughly 92x stake per buy.
Medium budget (€500-1,000)
Bonus buy at €50 (€0.50 stake) = 10-20 buys. You can expect to hit 1,000x+ regularly. Strategy: alternate buys and grinding with Ante Bet activated.
Large budget (€2,000+)
Bonus buy at €100-€200. Here you're seriously chasing the 10,000x max win (probability 1/2.7M). Extreme patience is required — recommended only if your bankroll allows for 50+ consecutive buys.

Hold & Spinner vs. Big Bass Splash — which to choose?
Hold & Spinner = 10,000x max win (vs. 5,000x), a unique mechanic, Multiplier Trail. Splash = a simpler mechanic, direct x2/x3/x10 multipliers. Hold & Spinner is more modern and more generous. Our favorite of the classic franchise.
