Quick verdict: Big Bass Halloween 3 is a Pragmatic Play slot from October 2025 with a 96.5% RTP and a 5,000x max win. This time the fishing trip has turned into a zombie story: one of the two fishermen is now a zombie, and the reels sit in a shed with bloody handprints on the windows. It plays on 5 reels, 3 rows and 10 paylines, and almost everything happens in free spins, where a red and a blue fisherman each fill their own meter and push fish money multipliers up to 10x. Most sources rate it high volatility; OLBG goes further and calls it very high.

Base game: line wins and scatter helpers
- Paylines: 10 fixed lines on a 5×3 grid, paying left to right from reel 1. The royals (10 to A) pay 5x to 10x your stake for five on a line, and the premium symbols (fish, backpack, axe, lure and van) pay 20x to 200x, with the van at the top.
- No wilds in the base game: the fisherman wilds only appear once free spins start, so base spins are mostly about chasing scatters.
- Fish money symbols: fish can land with a cash value from 2x to 5,000x your stake. In the base game these values are just for show; they are only collected during free spins.
- Two-scatter helpers: when two scatters land, a random feature may try to bring in the third. Reviews describe a respin with the scatter reels held and a hook that drags a reel up to reveal another scatter. Neither is guaranteed.
- Ante Bet: raises your stake to 1.5x to make the free spins trigger more often.
Free spins with the red and blue fishermen
Three, four or five scatters award 15, 20 or 25 free spins. SlotCatalog and AboutSlots both put the trigger rate at about 1 in 113 spins.
- Two fisherman wilds take part: a red one and a blue one. Each substitutes for the regular symbols and collects the value of every fish money symbol on screen when it lands.
- Every fisherman that lands goes into its own colour meter, so the red and blue sides progress separately.
- Every 4th fisherman in a meter adds 10 free spins and lifts that meter’s collection multiplier: 2x at the first step, 3x at the second and 10x at the third. Once a meter reaches 10x it gives no more extra spins.
- Random modifiers can step in on spins that would otherwise miss: dynamite drops fish onto the reels when fishermen land without any fish, a hook pulls a fisherman into view when fish land without one, and a shark can change the symbols on screen.
Bonus buy: yes, where the casino offers it. Free spins cost 100x your stake. Super Free Spins cost 300x and only need 3 fishermen, not 4, to move each meter up a level and add spins. Hideous Slots and FruitySlots both list the buy options at the same 96.5% RTP as the base game.
Is the RTP 96.5% or 95.5%?
Both, plus a third version: 96.5% is the standard setting, and casinos can also choose 95.5% or 94.5%. OLBG, Casinos.com, Gambling.com, PokerListings and SIGMA all give 96.5%. SlotCatalog’s stats table shows 95.5% while its own review text says 96.5%. AboutSlots lists all three settings, and Hideous Slots gives the range as 94.5% to 96.5%. In practice that is a full two points between the best and worst version, on a game where most of the return is locked up in a bonus that comes about once every 113 spins. Open the paytable before you play and look for 96.5%.

Big Bass Halloween 3 FAQs
What is the max win on Big Bass Halloween 3?
5,000x your stake, according to OLBG, SlotCatalog, Casinos.com, Gambling.com and PokerListings. SlotCatalog and AboutSlots put the odds of reaching it at about 1 in 2.5 million spins.
How many free spins can you get?
15, 20 or 25 at the start, for 3, 4 or 5 scatters. Each meter can then add 10 spins three times (at its 4th, 8th and 12th fisherman), so with two meters running there are up to six retriggers in one round. SlotCatalog, AboutSlots, Hideous Slots and FruitySlots all describe the same steps.
What do the red and blue fishermen do?
They are the two wilds of the free spins round, and each one collects fish money values into its own meter. OLBG, AboutSlots and Hideous Slots all note the separate red and blue meters, so a big multiplier on one side does not carry over to the other.
Is Super Free Spins worth 300x?
It costs three times the normal 100x buy, and in return each meter levels up after 3 fishermen instead of 4, so the 10x multiplier is easier to reach. Hideous Slots and FruitySlots list both buys at 96.5%, so neither has a better long-run return than spinning normally; Super Free Spins just puts more of your stake into one bonus.
Can I play Big Bass Halloween 3 for free?
Yes. The free demo at the top of this page is Pragmatic Play’s own demo and plays with free credits, so you can try the bonus before playing for real money. It loaded when we tested it on 16 October 2026.
