22 Jan 2026Prepare to be spooked out in the Halloween-themed slot Big Bass Halloween 3.
Pragmatic Play has put a scary twist on the popular Big Bass franchise, this time dressing the intrepid fisherman up as a crazed zombie.
This may be the 29th game in the Big Bass franchise, and it is essentially a reskin of Big Bass Vegas Double Down Deluxe, so it should look familiar.
A chilling tone greets players when they spin the reels of Big Bass Halloween 3 for the first time.
The dark and sinister classical beat underline this game, and it helps to enhance the atmosphere.
Axes and blood-splattered vans feature in what appears to be a fish tank. A swampy and eerie lake provides the backdrop under a haunted sky.
There is a neon flair to this title, but Big Bass Halloween 3 boasts great aesthetics, and it is well-optimized for mobile play.
Big Bass Halloween is played on a 5ₓ3 grid, with up to 10 fixed paylines.
Wins are assembled by matching at least 3 symbols across any of the paylines. The top-tier symbol is represented by the van, offering a maximum win of 200ₓ your bet for creating a full line.
Meanwhile, the royals are lower-paying symbols, offering a return of up to 10ₓ your bet for a 5-of-a-kind combination.
The fish symbols double up as Money Symbols in Big Bass Halloween 3. They can land with cash prizes values of 2ₓ, 5ₓ, 10ₓ, 15ₓ, 20ₓ, 25ₓ, 50ₓ, 100ₓ, 200ₓ, 500ₓ or 5000ₓ the total stake.
Hit at least 3 Scatters to activate the Free Spins Feature. Three, 4, or 5 Scatter symbols offer up 15, 20, or 25 free spins, respectively. During the round, Wild Fishermen collect the value of all the Money Symbols on the reels.
Blue and Red Fishermen are collected in their own blue or red meter. Every fourth Fisherman that lands retriggers the feature, with an extra 10 free spins added, and this increases the Fish Money symbol multiplier.
Big Bass Halloween 3 comes with a maximum win worth 5,000ₓ the total bet.
