Pragmatic Play · 2023
Big Bass Halloween is a high volatility 5x3 slot from Pragmatic Play. The page shows how a round runs, what symbols pay and how bonus modes work.
A 5x3 grid with 10 paylines blends Fishing, Halloween, Horror and Zombies themes into one board. Wins start on the leftmost reel and run across adjacent reels, and two matching symbols are enough to pay. Each spin, the small fish cluster MONEY symbol carries a random cash value. The rest of the symbols are the Lifebuoy ring, Fishing hook, Crow, Tackle box and card faces from 10 to A.
Three to five SCATTER symbols anywhere trigger Free Spins of 10, 15 or 20 spins. Inside Free Spins, WILD symbols land on all reels and collect the visible MONEY cash values each spin. A 12-cell progress ribbon adds 10 spins at the 4th, 8th and 12th collected WILD, up to three retriggers. The Ante Bet raises the total bet and the SCATTER hit chance.

Big Bass Halloween basics
Useful before your first spin, when you pick a bet and want to see the whole round.
A$0.10 is the lowest bet and A$375 the highest, and you set the stake before each spin. Examples on this page use A$0.40, A$1 and A$2.
Ten paylines on a 5x3 grid pay left to right from the leftmost reel. Two matching symbols on adjacent reels can already win, and small fish MONEY symbols show cash.
Eight cash values, from 2x to 2000x the total bet, sit on the small fish MONEY symbol. Each spin draws a new random value, so results vary.
Three scatters give 10 spins, four give 15, five give 20, anywhere on the grid. Free Spins then put WILD on every reel and collect all visible MONEY values.
Each A$0.10 minimum spin costs the same whether you win or lose, so set a total amount before the first spin.
Big Bass Halloween features
After this you will know how each round starts, what happens inside it, and what it costs you.
3/4/5 SCATTER symbols anywhere trigger Free Spins of 10/15/20 spins. Each spin, WILD appears on all reels and collects every visible MONEY cash value. A 12-cell progress ribbon retriggers +10 spins at the 4th/8th/12th collected WILD, raising the MONEY-collection multiplier to 2x/3x/10x. Retriggers are capped at 3.
Base game spinsCollected MONEY cash
1.5x the total bet is the price of this toggle, so A$2 becomes A$3 at the example top bet. Ante Bet ON raises the natural chance of landing SCATTER symbols and hitting Free Spins. While it is ON, Buy Free Spins is disabled.
Standard betMore Scatter landings
100x the current total bet buys the Free Spins round directly. At the example top bet of A$2, that is A$200. The purchase is disabled while Ante Bet is ON.

Worried you will miss the bonus when it starts? These screens show what to expect.
100x the total bet is the price of the Free Spins round, or A$200 at the A$2 example top bet.

A$100 staked returns A$96.06 on average over a very large number of spins. A single session can land above or below that. The version Midnight Casino runs is shown in the game rules.

10 paylines on a 5x3 grid give no warning before a bonus. Scatter symbols land at random, so the Free Spins can arrive on the next spin or after a long dry run. How often the bonus round comes cannot be known in advance. The result of one session is random too, whatever the RTP says.
96.06% is the RTP figure, but the version Midnight Casino runs appears only in the game rules. Read the game rules before you stake, since that is the only place the version is shown. Until then, read 96.06% as a long-run average, not a promise.
x2,100 is the highest multiple of the bet this slot can pay, and it is a ceiling that is reached very rarely. The money values for each bet sit in the table, and the ceiling is a limit, not a target.
Four questions answered
Read this before your first spin, or when you wonder how the bonus starts.
The maximum win is 2,100 times the bet. Big Bass Halloween has high volatility, so wins come less often and can be large when they land. Plan your stake with that in mind.
A$0.10 is the lowest bet on Big Bass Halloween, so you can test the reels cheaply. The paytable is built for A$0.40 bets, so check the symbol payouts there before you raise your stake.
3 SCATTER symbols anywhere on the reels start Free Spins with 10 spins. 4 give 15 spins and 5 give 20. Ante Bet raises the chance of landing SCATTER symbols.
100 times the total bet is the price of the Free Spins round. At the A$2 example top bet that is A$200. The purchase is unavailable while Ante Bet is on, so switch it off first.

Play is for 18+ only. For help in Australia, call the National Gambling Helpline on 1800 858 858, or use the BetStop register.
Before the first spin, decide how much money you can lose without harm to your bills. Put that amount aside and stop when it is gone.
Choose your stop point before you spin, and keep it after a big win too. A win on the reels does not change the limit you set.
Use the deposit and loss limits in your account to cap what you put in. Set them before you open the game, not during a losing run.
If the game stops being fun, take a break from the reels. Self-exclude if you feel you cannot stop on your own.
