Big Bass Hold & Spinner is Pragmatic Play's fishing-lodge answer to the hold-and-spin formula. Land fish symbols on the 5×3 grid and they lock; spin again with fresh reels behind them, stacking multipliers and triggering free spins when scatters land.
How it plays
Ten fixed paylines across a 5×3 grid. Bet £0.10 to £250. The mechanic turns on fish symbols — land one, it locks for a respin. Land more fish, they all lock and respin again. Multipliers climb with each hold, and the variance sits high: expect long droughts punctuated by sudden 20–30x payouts when the multiplier stack kicks in.
The bonus round
Three or more scatters trigger free spins. During free spins, every fish that lands locks and stays locked across the entire bonus round — no resets, only multiplier growth. A single cascade of locks can hit 100x or more. The 4,000x ceiling lives here, in the intersection of locked fish, free-spin multipliers, and a final high-multiplier respin.
Who it's for
Volatility seekers who understand the rhythm of hold-and-spin slots and can absorb 50-spin dry patches for one locked-fish cascade. The fishing theme appeals to players who like immersion; the mechanics reward patience and patience.
Avoid if
You chase small, frequent wins or play on a tight bankroll — Big Bass Hold & Spinner swings hard and can exhaust a session budget before the lock sequence triggers.

Land a fish, it locks for a respin. Every subsequent fish that lands also locks. Multipliers grow with each new lock. Scatters trigger free spins; fish in free spins stay locked across all remaining spins.
It's rare but real — it hits when a full grid of locked fish aligns with a high multiplier stack in free spins. Expect 20–50x more often; 4,000x happens to a small fraction of sessions, not every week.
