Big Bass Halloween Review: Our Verdict
UnionSlots rating: 7/10. Big Bass Halloween takes the original Big Bass Bonanza formula and dresses it up for spooky season, so it suits players who already enjoy that game and fancy a seasonal change of scenery. The free spins are easy to follow: fishermen collect fish, every fourth fisherman adds spins and lifts the multiplier on fish values, and a round that reaches the 10x level can pay very well. The catch is a bare base game, an average 96.04% RTP and a fairly modest 2,100x top prize.
Pros
- Money fish carry cash values from 2x up to 2,000x the stake, so a single collect can be worth a lot.
- Every fourth fisherman collected adds 10 free spins and raises the fish multiplier to 2x, then 3x, then 10x.
- When a fisherman lands with nothing to collect, random fish can be added to the reels at the end of the spin.
Cons
- The base game has no features of its own: fish are only collected in the free spins.
- The 96.04% RTP is only average, and casinos can run lower-RTP versions.
- Apart from the Halloween look it plays like Big Bass Bonanza, and the 2,100x maximum win is modest.

How Big Bass Halloween Works
The layout is classic Big Bass: five reels, three rows and 10 paylines, with crows, hooks and fish among the symbols. The fish are money symbols that land with a cash value of between 2x and 2,000x the stake, but in this game those values are only collected during the free spins, so the base game comes down to line wins and waiting for the blood-soaked scatters. Three or more of them start the feature.
Free Spins
Three, four or five scatters award 10, 15 or 20 free spins. The hook-wielding fisherman now lands as a wild, and whenever he appears with fish on the reels he collects all of their cash values. If a fisherman lands with no fish to reel in, the game can drop fish onto random positions at the end of the spin, giving him something to collect.
Retriggers and Multipliers
Each fisherman you collect moves a meter above the reels along, and every fourth one retriggers the round with 10 more free spins. Each retrigger also boosts the value of fish collected from then on: 2x after the first, 3x after the second and 10x after the third. The third retrigger is the last one available, so the 10x level is the top of the ladder and the stage where the biggest collects become possible.
RTP, Volatility and What to Expect
Pragmatic Play publishes a 96.04% RTP for Big Bass Halloween. UK casinos can run lower RTP versions; check the game’s info screen. Volatility is medium-high, rated 4 out of 5, and the maximum win is 2,100x the stake. Expect long spells of small line wins while you wait for scatters, then a bonus whose value depends on how many fishermen turn up and how far up the multiplier ladder you climb. Big Bass Halloween 2 and Big Bass Halloween 3 are separate, later games with different maths, so check which one you have open.
