Big Bass Boxing Bonus Round

From reels of bass to a boxing ring

Picture a fishing trip that has wandered into a boxing gym: that is Big Bass Boxing Bonus Round, a five-reel, three-row slot from Pragmatic Play's Reel Kingdom studio with ten fixed lines paying left to right. Two matching symbols on a line already pay, and the Money Fish carry cash values that the boxer wilds collect during the bonus rounds.

Boxers are the difference here. Blue and Red wilds fill their own meters, every fourth one adds spins and lifts the multiplier, and random camera, hook and knock-out moments can land mid-round. Spins can also be bought outright for a faster start, and a side bet raises the odds of the chase.

Play sequence

Before the first spin lands

Most players hesitate over what a spin costs before the first press.

  1. A$0.10 to A$375 range

    Pick a bet from A$0.10 to A$375 before the first spin. Every spin costs that bet, and payouts on the 10 fixed paylines scale with it.

  2. When the reels stop

    Look at the 10 fixed paylines after each spin. A win forms when two or more matching symbols land in a row along a payline, read left to right.

  3. Big Bass Boxing Bonus Round Scatter

    Switch on the Ante Bet to pay 1.5 times your bet per spin. WILD symbols stay out of the base game, while 3 to 5 Scatter symbols start the bonus.

  4. Between 15 and 25 spins

    Land three to five Scatter symbols for 15, 20 or 25 free spins. Blue and Red WILD boxers then appear on every reel and collect Money Fish values.

  5. Keep play within your budget

    Set a budget before the first spin, and stop once it is gone. Nobody can know in advance when a bonus round comes or how a session ends.

Spins Without Rebuying

Follow the Two Boxers Through a Round

The worry is usually how the bonus begins, so here is each route laid out plainly.

Big Bass Boxing Bonus Round Free Spins

Three to five SCATTER symbols open Free Spins: 15, 20 or 25 spins. Blue and Red WILD boxers land on all reels and collect MONEY values. Each fourth WILD on a colour's meter adds 10 spins and lifts that multiplier through 1x, 2x, 3x and 10x.

Blank reelsFree spins

Super Free Spins Chosen Up Front

Super Free Spins begin with 15 spins and both WILD meters already filled to the third slot, so the first boxer of each colour retriggers at once: 10 more spins and a 2x multiplier. Each meter then needs 3 WILDs, not 4, to step up again.

Menu panelRich start

Ten Paylines With No Wilds

Base Game runs 5x3 reels across 10 fixed paylines that read left to right. WILD symbols stay out of it entirely, leaving MONEY Fish to gather on the reels, while the two BUY buttons and the Ante Bet toggle wait on the left panel.

Spin Knowing These Three Limits

Starting a session, you get no schedule for the bonus round, because nobody does. How often the scatters land is random, and one session's result is random too, whatever the return figure says. The published RTP describes a long run of play, not the night in front of you. A run of losing spins and a run of winning ones are equally possible, and neither is owed to you in any order.

Choosing a game, you will find which return version is running only in the game rules screen, not on the lobby tile. Setups differ, and the figure you see quoted elsewhere may belong to another version. Open the rules once inside the game if that number decides the session for you.

Chasing the big figure, you should read it as a ceiling, not a target: the maximum win is a cap that was set at the design stage. It arrives very rarely, and most sessions end well below it. Planning around that number, rather than expecting it, keeps a bad run in proportion.

Two Ways To Spin

A Look at the Boxing Ring Before You Stake

You will know which path suits you, a no-money look or a staked round from your account.

Trying Big Bass Boxing Bonus Round here costs nothing and pays nothing back. Staking on it needs a Rainbet account and you at 18 or over.

Five quick replies

From guessing to knowing the Big Bass Boxing rules

You will leave knowing the rules, the costs and the RTP before you place a single bet.

Is Big Bass Boxing Bonus Round different from other Big Bass games?

This slot runs a 5x3 grid with 10 fixed paylines, and Blue and Red WILD boxers collect Money symbol values during free spins. Its own mechanics are the Money collect, the colour meters and the retrigger rules, so compare those, not the name.

Can I buy the free spins in Big Bass Boxing Bonus Round?

Yes, the buy sits on the left panel, with Free Spins at 100 times the total bet and Super Free Spins at 300 times. The Ante Bet is a separate toggle that raises the stake by 1.5 times, so it is not the same as a buy.

How do free spins start in Big Bass Boxing Bonus Round?

Three to five SCATTER symbols start the round, and the spin count is 15, 20 or 25. Those spins can grow: every fourth WILD of one colour adds 10 spins.

What is the RTP of Big Bass Boxing Bonus Round?

This slot has one RTP, 96.50%, which is the long-run return over a very large number of spins. It is not a prediction for one session, and it cannot tell you what a single visit will return.

How volatile is Big Bass Boxing Bonus Round?

Volatility is high, so wins can come in bigger swings with quiet stretches between them. Nobody can know in advance when the bonus will come or how a session will end.

Budget limits for every session

Players must be 18+. Call the National Gambling Helpline on 1800 858 858, or join BetStop, the national self-exclusion register, at any time.

Budget first, spins second

Decide how much you will spend before the first spin. Keep that amount apart from money you need for bills, and stop when it is gone.

Same stop, win or lose

Choose your stopping point before you start, and honour it after a win as well as a loss.

Deposit and loss limits, set calmly

Set deposit and loss limits in your account before you play, so the choice is made when you are calm. Review them whenever your plans change.

From fun to pause

If the game stops being fun, take a break. For more distance, self-exclude through BetStop, and treat a pause as a sensible step.
