Big Bass Bonanza is a fishing-themed slot with free spins

When wins arrive, they can be big
Big Bass Bonanza is a fishing-themed slot on a 5-reel, 3-row grid released in 2020 by Pragmatic Play. Wins form on 10 paylines running left to right from the leftmost reel, and three matching symbols on a line trigger a payout. The game combines a calm ocean setting with the tension of high volatility, where wins arrive less often but can grow significantly larger. Free Spins mode activates the core mechanic: a Fisherman Wild that collects the values of Money symbols across the reels.
Is this slot right for you?
This slot suits players who enjoy longer play sessions and can handle swings between dry spells and substantial payouts. The high volatility means you need a bankroll that can weather a run without wins, but the Free Spins feature and Money Collect mechanic reward patience with potential for larger payouts. At example bets of A$5 or A$10, the game is accessible to most players, though the maximum win of 2100 times your bet appeals to those chasing bigger rewards.
Before and after the Scatters land
Free Spins is the mode that defines a round in Big Bass Bonanza. Landing three or more Scatter symbols triggers it, awarding 10, 15 or 20 free spins depending on how many Scatters land. During Free Spins, the Fisherman Wild appears on every reel and collects the values shown on Money symbols that land beside it, accumulating wins without needing matching symbols. Every fourth Wild collected adds 10 more spins and escalates the Money multiplier, and this can happen up to three times, pushing the maximum win to 2100 times your stake.

Big Bass Bonanza step by step

Playing one round: bet, spin, collect

Follow what happens on the reels from the moment you set your stake to when the round ends.

  1. 1

    How much can you bet?

    You choose how much to stake on each spin. Big Bass Bonanza lets you bet from A$0.10 up to A$250. Your bet size changes what you can win: a A$10 stake can return up to A$21,000 if the top prize lands.

  2. 2

    Three symbols and you win

    Matching symbols form wins across the 10 paylines that run left to right from the leftmost reel. You need at least 3 of the same symbol to land a winning combination. The Lure symbol pays from just 2 matches.

  3. 3

    What happens on a regular spin

    During a base game spin, the reels show standard pay symbols across the 5x3 grid. The Fisherman Wild does not appear in the base game, so you collect payline wins from the other symbols on each spin.

  4. 4

    When Scatters unlock the bonus

    Free Spins begin when 3 or more Scatter symbols land on the reels. You earn 10 free spins for 3 Scatters, 15 for 4, or 20 for 5. The Fisherman Wild becomes active during free spins and collects Money symbol values from the reels.

  5. 5

    Taking a break on your terms

    Before you start playing, you can set a session time reminder through Kinghills Casino. This helps you stay in control of how long you play and keeps your gaming within limits you choose.

Free spins and Money Collect feature

How free spins trigger and retrigger

Three or more Scatters land to start your free spins. You receive 10 free spins for three Scatters, 15 for four, or 20 for five. During free spins, the Fisherman Wild appears on all reels and collects Money symbol values. Each fourth Wild collected adds 10 more free spins and escalates the Money multiplier. You can retrigger up to three times, with multipliers climbing to x2, x3, and x10. The bonus round caps at a 2100x win.

Play the base game until Scatters land

In base game mode, the five reels and three rows show standard pay symbols only. The Fisherman Wild does not appear here. Wins form across ten paylines running left to right from the leftmost reel. You spin the reels and match symbols to land wins on these fixed paylines until a Scatter lands.

The honest limits

Some things no review will tell you

The bonus round's timing

When the Fisherman Wild lands to start collecting money symbols depends on chance alone. You might trigger free spins quickly or play many rounds without reaching the bonus.

Your session is always random

Big Bass Bonanza returns 96.71% over time, but one session can give you much more or much less. The RTP describes long-term play across many spins, never what happens to you today.

Can you really win the maximum?

The top prize of A$525,000 exists in the game, but reaching it happens extremely rarely. Most sessions end far below the maximum possible win.

Big Bass Bonanza and staying in control

Play within limits you set first

Set boundaries before you play so the slot stays entertainment, not a reason to keep betting.

Big Bass Bonanza needs a budget
Decide how much you can afford to lose on Big Bass Bonanza before you start playing. Losing money you set aside for this game means the session is over, even if the free spins round feels close.
Deciding when to stop
Set a point in advance where you stop playing, whether you are ahead or behind when you reach it. Walking away after a win is as important as stopping when your budget is spent.
Big Bass Bonanza respects your account limits
Use your account's deposit limits and loss limits to enforce the boundaries you have set. These tools help you stick to your plan when the game momentum makes it harder to decide.
Pausing or stepping away
If playing Big Bass Bonanza stops being a break and starts feeling like something you need, pause or use self-exclusion. Help is available through Gambling Help Online, Lifeline Australia, and the BetStop National Self-Exclusion Register.
