A 5x3 grid, 10 paylines and high volatility: Big Bass Halloween 3 from Pragmatic Play. Read its figures, modes and costs before the first spin.
The 5x3 grid of Big Bass Halloween 3 mixes fishing with horror and zombies. Its symbols include a Zombie Van, an Axe, a Backpack and the card symbols. The game runs 10 paylines from left to right, and a win starts with 2 matching symbols on a payline. On the fish symbols, a random money value shows on each spin. In the base game you see these values but cannot collect them.
Two WILD FISHERMAN trackers, blue above the reels and red below, drive the free spins. Each WILD collects the visible money values, and every fourth WILD of one colour adds 10 free spins and lifts the multiplier. Super Free Spins need only 3 WILD FISHERMAN of any colour across both trackers to retrigger. Dynamite Spin and Hook events also run in free spins.

Extra spins for you
After this, you will know how each mode starts and what happens once it is running.
Three, four or five SCATTER start Free Spins with 15, 20 or 25 spins. Two WILD FISHERMAN trackers run. Every fourth WILD of one colour in a meter adds 10 spins and lifts the multiplier from 1x to 2x, 3x and 10x. Wins cap at 5000x the total bet.
Base GameFree spins
Three or more SCATTER start Super Free Spins, which follow the Free Spins rules. Three WILD FISHERMAN of any colour across both trackers combined retrigger it, instead of four of one colour per meter. Dynamite Spin and Hook stay active, and wins are capped at 5000x the total bet.

Big Bass Halloween 3
Win365 Casino lays out each round in plain steps you can check before you bet.
A$0.10 is the smallest bet and A$375 the largest. Every payout scales with the bet: A$10 pays ten times what A$1 pays on the same win.
10 paylines run left to right across the 5x3 grid, and a win needs 2 matching symbols. Fish symbols show a random MONEY value each spin, visible but not collectible.
The base game uses the Scatter and Wild features, and Multiplier and Money Collect wait until the free spins start.
3, 4 or 5 SCATTER symbols start 15, 20 or 25 free spins. A blue strip above the reels and a red strip below track the WILD FISHERMAN symbols.
Set a spending limit before the first spin. Nobody can know in advance how often the bonus comes or how a session ends, and a higher bet speeds up the balance.
Four screens
These screens settle how the free spins and win screens look in play, before the first spin.
96.50% is the long-run return for every A$100 staked, and it says nothing about how often the bonus round arrives. How often Free Spins start is not known in advance. The result of one session is random whatever the RTP, so a session can end well above or well below the stake.
96.50% applies to the version on this page. Which RTP version the lobby runs is shown only in the game rules, and some other titles in the series run 96.51% or 96.52%, so read the rules before the first spin.
x5,000 of the total bet is the ceiling for this slot, and a win that size is reached very rarely. Free Spins also cap the total win at the same multiple of the bet. Nobody can tell in advance whether a session will come near that ceiling.

Start playingKnow what to expect
Most players worry about how much a bet costs and how big a win can get.
96.50 is the RTP here, and Big Bass Blast, Big Bass Football Bonanza and Big Bass Trophy Catch share it with the same x5,000 maximum win. Big Bass Raceday Repeat returns 96.51, and Big Bass Splash 1000 returns 96.52 with a maximum win of x25,000.
Three, four or five SCATTER symbols start the Free Spins, giving 15, 20 or 25 spins. Three or more SCATTER symbols also start the Super Free Spins, which need only three WILD FISHERMAN to retrigger.
The minimum bet is A$0.10 and the maximum bet is A$375. A$1 and A$10 are only examples used on this page, not the limits of the game.
Big Bass Halloween 3 is in the Win365 Casino game lobby. The smallest bet is A$0.10, so you can start small and see how the rounds run for you.
x5,000 times the bet is the maximum win, so an A$10 bet can reach A$50,000. At the highest bet of A$375, the same limit comes to A$1,875,000. The Free Spins are capped at the same x5,000 times the total bet.
x5,000 is the top win, and the high volatility means wins are less frequent but can be large when they land. How often the bonus comes cannot be known in advance, so a session can end either way.

A$0.10 is the smallest bet, so set a session budget before you open Big Bass Halloween 3 and treat that amount as money you can lose.
At the A$1 paytable bet, decide your stop point before the first spin and keep to it after a win too.
A$375 is the highest bet, and a few spins at that size can use up a deposit fast. Set deposit and loss limits in your account first.
A$10 bets add up fast, so when rounds stop feeling fun, take a break or self-exclude. Chasing losses is a clear sign to step away.
