Get to know Big Bass Bonanza 1000 first

A 5x3 grid with 10 fixed paylines, running left to right, frames this fishing slot. Two matching symbols on a line can start a win, and the card symbols A, K, Q, J and 10 cover the lower end. The high fishing symbols are Fishing Bobber, Dragonfly, Fishing Rod, Tackle Box and Fish Pile, and the fish carry money values you can read on the reels.

Three Scatters start 10 free spins, four start 15 and five start 20, played on special reels. In those spins the Wild Fisherman sits on all five reels, and a landing Wild collects every visible money fish value at once. A Wild Tracker above the reels counts Wilds: each fourth one adds 10 more spins with a rising multiplier, up to three retriggers.

Play guide

Pick your bet and start the reels

5 steps show the bet, the first wins, the free spins and the limit, in order.

  1. Know what your stake changes

    A$0.10 is the lowest bet and A$375 the highest, so the stake you pick scales every payout. Example figures here use A$1, A$2 and A$10.

  2. Follow the paylines left to right

    5x3 grid with 10 fixed paylines read left to right. Two matching symbols on a payline can already pay, and WILD never appears in the base game.

  3. Near-miss respin and hook

    2 Scatters in a near miss can randomly trigger a respin, where Scatters drop one row, or a hook animation that gives a chance at a third Scatter.

  4. Entry tiers for Free Spins

    3 Scatters trigger 10 Free Spins, 4 Scatters trigger 15, and 5 Scatters trigger 20. Free Spins are played on special reels, and Wild Fisherman is active on all five.

  5. What can be known in advance?

    A$10 is the example top bet on this page. Set your loss limit before the first spin, because no session result can be known in advance.

Paid features and their price tags

100x and 450x the total bet are the two buy prices, and the money at the top example bet of A$10 is in the table.

Big Bass Bonanza 1000 free spins and bonus features

At 22aud Casino we set out each mode's rules before the first spin.

Land 3 Scatters for 10 free spins

3, 4 or 5 Scatters trigger 10, 15 or 20 free spins. On all 5 reels, each WILD collects every visible MONEY FISH value. Every 4th WILD is a group milestone worth 10 free spins, with multipliers climbing x2, x3, then x10. Max 3 retriggers add 30 free spins.

Base Game spinsFree spins, multipliers

Base spins to 1000x MONEY fish

Super Free Spins give 15 spins at 450x total bet, with enhanced probability of a 1000x MONEY FISH value appearing on the reels. Same WILD Fisherman collection and Wild Tracker retriggers as regular Free Spins, with x2, x3 and x10 multipliers.

Base GameEnhanced MONEY FISH

Money values on the fish

The grid is 5x3 with 10 fixed paylines, read left to right. WILD does not appear here. Fish symbols show random MONEY values on the reels. Two Scatters can randomly trigger a respin, where Scatters drop one row, or a hook animation with a chance at a third Scatter.

Is a trial game enough before real stakes?

At 22aud Casino the free version opens first, so you choose your stake knowingly.

The demo needs no money and pays nothing, so every spin is practice. The real game needs a 22aud Casino account and you must be 18 or older.

Play for money

Known RTP, unknown session: where the figures stop

The 96.51% RTP is a return over a very large number of spins, not a promise for one session. How often the bonus round comes is not known in advance, and the result of one session is random. Two players on the same game can finish with very different balances, even though the RTP is identical.

A$100 staked is the basis of the RTP figure. Which RTP version this lobby runs is shown only in the game rules, so open them from the lobby before the first spin and note the version named there.

A$7,500,000 is the top win at the A$375 maximum bet, which is 20,000 times the stake. The maximum win is a ceiling reached very rarely, and no one can plan for it. At the A$10 example bet the same ceiling is A$200,000.

5 quick answers

Your first session: the questions answered

At 22aud Casino we put bets, wins and bonus costs in plain figures before you spin.

How volatile is Big Bass Bonanza 1000?

The 5x3 grid runs at high volatility, so results swing hard. Long stretches without a big win are normal for this type of game, and a single bonus round can change the balance quickly. The RTP of 96.51% does not change that swing.

Can I buy free spins in Big Bass Bonanza 1000?

A$1,000 buys the free spins at an A$10 bet, which is 100x the total bet. The super free spins cost A$4,500 at the same bet, or 450x the total bet. Buying skips the base game, so the bonus starts at once.

What bet sizes can I play in Big Bass Bonanza 1000?

A$0.10 is the lowest bet and A$375 the highest, with A$1, A$2 and A$10 as the example bets. The paytable is shown at an A$1 bet, so you can scale each payout to your own stake.

What is the maximum win on Big Bass Bonanza 1000?

x20,000 the bet is the maximum win, which pays A$200,000 at an A$10 bet. At the highest bet of A$375 the same multiple reaches A$7,500,000. No session can be planned around that cap.

How is Big Bass Bonanza 1000 different from the other Big Bass slots?

96.51% RTP with a x20,000 maximum win is a pairing no other title in the series shares. Big Bass Splash 1000 lists 96.52% and x25,000, while the other four Big Bass titles list 96.50% or 96.51% with x5,000.

18+ only. Get help from the National Gambling Helpline on 1800 858 858, or register with BetStop, the national self-exclusion register.

Budget set, then play

A$375 is the highest bet, so set the session budget before the first spin, and treat each spin as a real cost.

Stop after a big win?

96.51% is the long-run return, and one win does not change that, so decide the stop point before a big win or a dry run.

Loss caps and account settings

A$10 is an example bet, so at a higher stake the same losses arrive faster; set deposit and loss limits in your account before you start.

Pauses and self-exclusion

5x3 grid and high volatility make long sessions hard to judge, so take a pause when the game stops being fun, or self-exclude.
