Five reels and three rows form the 5x3 grid of Big Bass Bonanza 1000, a fishing-themed slot from Pragmatic Play. Ten fixed paylines run left to right, and a win needs at least 2 matching symbols on one of them. The high fish symbols carry random money values that show on the reels. Base game has no WILD, so every win comes from matching the symbols themselves.
Three, four or five Scatters start 10, 15 or 20 free spins on special reels. The Money Collect feature runs through WILD Fisherman, who sits on all five reels and collects the visible money fish values. Each 4th WILD on the Wild Tracker adds 10 spins and lifts the Multiplier from x2 to x3, then x10. Up to 3 retriggers add 30 spins more.
Extra spins explained
Most players worry about how many spins a trigger gives before the first spin.
Landing 3, 4 or 5 Scatters triggers 10, 15 or 20 free spins. The WILD Fisherman is active on all 5 reels, and each WILD collects every visible MONEY FISH value. Every 4th WILD on the Wild Tracker adds 10 spins and lifts the multiplier from x2 to x10.
Base gameFish money collected
15 spins at 450x total bet form Super Free Spins, with an enhanced chance of 1000x MONEY FISH value appearing on the reels. The same WILD Fisherman and Wild Tracker rules apply as in Free Spins.
Base gameBoosted fish values
5x3 grid with 10 fixed paylines, read left to right. WILD does not appear. Fish high symbols carry random MONEY values. A near miss of 2 Scatters can trigger a respin, dropping them one row, or a hook animation with a chance at a third Scatter.

Round Guide
5 steps below show what the screen does before and after each spin.
A$0.10 to A$375 is the bet range. Choose a stake before the first spin; all 10 fixed paylines stay active at any bet.
5x3 grid, 10 fixed paylines read left to right, and 2 matching symbols can already pay. WILD never appears in the base game, so each line uses only its own symbols.
2 Scatters in a near-miss can trigger a respin, where Scatters drop one row, or a hook animation for a chance at a third Scatter.
3, 4 or 5 Scatters trigger 10, 15 or 20 free spins on special reels, and the WILD Fisherman stays active on all 5 reels.
A$375 is the top stake, so set the session budget before the first spin and keep to it. Support is available from the National Gambling Helpline on 1800 858 858.
Both purchases cost a set multiple of the bet: at A$2, the free spins cost A$200 and the super free spins cost A$900.

See the Bonus Clearly
3 screens show the bonus and free spins, so you know what they look like before you play.
10 fixed paylines run across the 5x3 grid of Big Bass Bonanza 1000, but no line tells you when the bonus round will come. How often it appears is not known in advance. Each session is random, and that holds whatever the RTP version of the game is, because the RTP is a long-run average over many spins, not a promise for one session.
96.50, 96.51 and 96.52 are the RTP values used across the Big Bass series. Which version Jackmillion Casino runs for a title is shown only in the game rules, so read them before you place your first bet.
x20,000 is the ceiling of Big Bass Bonanza 1000, counted as a multiple of the bet, and the game reaches it very rarely. A ceiling marks the most a win can reach, not an amount a player can expect. Whether any spin gets near it depends on chance, so no session can be planned around it.
Browsing the lobby
Jackmillion Casino lays out each slot in the same order: figures first, then the rules.
Six questions below
Useful before your first spin, or when you want the bonus rules in plain terms.
3 Scatter symbols on the reels trigger 10 free spins, 4 Scatters trigger 15 and 5 Scatters trigger 20. The free spins play on special reels with a WILD Fisherman active on all five reels. Up to three retriggers add 30 more free spins.
20,000x the bet is the top win of Big Bass Bonanza 1000, and its volatility is high, so payouts vary widely from spin to spin. At the A$2 example bet that top win is A$40,000. How often a large win lands cannot be known in advance.
96.51 is the RTP of Big Bass Bonanza 1000, and it is the only RTP version of this slot. RTP is a long-run average over many spins, so it does not predict one session. Per A$100 staked, the expected return is A$96.51.
A$0.10 can keep a first session small while you learn the rules. The paytable is based on a bet of A$0.20, and its payouts change with the stake you choose.
A$200 buys the free spins at the A$2 example bet, which is 100x the total bet. A$900 buys the Super Free Spins, 450x the total bet. Super Free Spins give 15 spins with a significantly enhanced chance of a 1000x MONEY FISH value.
5000x is the maximum win of the four other Big Bass titles in the series, while Big Bass Splash 1000 reaches 25000x against the 20000x of this slot. Series RTPs run from 96.50 to 96.52.
18+ only. In Australia, help is available from the National Gambling Helpline on 1800 858 858, and the self-exclusion register is BetStop.
A$0.10 is the lowest bet on Big Bass Bonanza 1000, so set a session budget before the first spin. Spend only money you can afford to lose.
20,000x is the top win on Big Bass Bonanza 1000, and a large payout should not move the stop point you set before the session.
A$375 is the highest bet allowed here, so stakes can rise far above the A$2 examples. Set deposit and loss limits in your account first.
A$2 is an example bet, and fun can fade at any stake. Take a pause when it does, and self-exclude if breaks do not help.
