Pragmatic Play · 2025
Big Bass Splash 1000 is a high volatility fishing slot by Pragmatic Play on a 5x3 grid. Here is how it pays and how the bonuses work.
The demo is free. The real game needs an account and you must be 18+.
Choose this game if you want a fishing-themed video slot played on a 5x3 grid, which means five reels with three rows each. Wins form on 10 fixed paylines, and symbols pay from left to right, starting on the leftmost reel. Two matching symbols is the fewest needed for a payout, so a short run from the left can already count as a win. Each spin is one round on the grid.
Take this slot over a plain reel game when you want features beyond the base game. Wild and Scatter symbols sit alongside two free spin modes, Free Spins and Super Free Spins. Money Collect and the Progressive Multiplier complete the feature list. The base game sets the pay rule: symbols pay left to right across the 10 paylines.

These screens settle what each mode looks like before you put money on the reels.
Five steps follow
At Winbig21 each step is laid out before the first spin, and the limit stays yours.
Set the bet anywhere from A$0.10 up to A$500 before you spin. The Ante Bet toggle in the sidebar changes the multiplier, so check it before each spin.
Wins pay from left to right, starting on the leftmost reel. Symbols must land on one of the 10 fixed paylines, and two matching symbols are enough to pay.
Wild symbols stand in for paying symbols, and Scatter symbols start the Free Spins. Money Collect and Progressive Multiplier are also part of this slot.
Scatter symbols start the Free Spins, a separate mode from the base game. Super Free Spins is a second free mode, so check which one you are in.
Decide your limit before the first spin, and stop when you reach it. Need help with play? Call the National Gambling Helpline on 1800 858 858.
Scatters just landed
Most players want to know how the bonus starts before they commit a bet.
Going for the bonus means reaching Free Spins from the base game, which runs 5x3 with 10 fixed paylines. The mode sits beside the Scatter and Wild symbols. Money Collect and the Progressive Multiplier are both in the slot's feature list.
Base game spinsBonus spins
Choose to aim for Super Free Spins, a separate bonus mode listed next to Free Spins. You reach it from the base game, which runs on 5x3 reels with 10 fixed paylines. The Scatter and Wild symbols are part of the same symbol set.
Base game playBigger bonus round
Turn on the sidebar toggle to switch the bet multiplier from 10x normal play to 20x. The higher multiplier gives a higher natural chance of Free Spins, with more Scatter symbols on the reels. The RTP with Ante Bet is 96.53%.
Normal playHigher Free Spins chance
Start with Base Game to learn the symbols before you raise your stake. The base game runs 5 reels x 3 rows with 10 fixed paylines, and symbols pay left to right from the leftmost reel. Volatility is high and the base RTP is 96.52%.
Opening the gameEveryday wins
Choosing a buy means paying a fixed multiple of your bet, so at A$0.50 Free Spins cost A$50 and Super Free Spins cost A$225.
| Bonus | Price | RTP |
|---|---|---|
| Free Spins at 100x bet | x100 · A$50 | – |
| Super Free Spins at 450x | x450 · A$225 | – |
Before the first spin, check how much of each A$100 staked comes back over a long run. The table shows the money for each version, and the version running here is in the game rules.
| RTP version | RTP | Default |
|---|---|---|
| Edition 1 | 96.53% | No |
| Edition 2 | 96.52% | Supported |
| Edition 3 | 96.51% | No |
Accept that you cannot know when the bonus round will come. How often it lands is not known in advance, so no figure on this page predicts it. One session is random whatever the RTP, and a higher RTP does not promise a win on your next spin.
Open the game rules before you play for real money. They are the only place that names the RTP version of the game you open. Check there first, because a figure in a lobby thumbnail does not tell you which version is running.
Treat the top prize as a ceiling, not as a result to plan around. The maximum win is the most the game can pay on one bet, and it is reached very rarely. A larger stake raises the money at that ceiling. Nothing in the game promises you will see it.

Play for realFive short answers
These short answers settle volatility, RTP, maximum win and demo access before you spin.
Big Bass Splash 1000 has high volatility. A high-volatility game pays unevenly, so a long stretch without a big win is part of how it plays. The largest prize is set by the bet, not by how long you play.
The slot runs on three RTP versions: 96.51%, 96.52% and 96.53%. The base game runs at 96.52%, and the other two versions sit at 96.51% and 96.53%. Each figure is a long-run return on A$100 staked, not a promise for one session.
Among the Big Bass titles, this slot has the highest maximum win at x25,000, against x5,000 for the rest. Its base RTP of 96.52% is also the highest in the series. Blast, Football Bonanza and Trophy Catch sit at 96.50%, and Raceday Repeat at 96.51%.
Read the paytable first, which shows what each symbol pays at an A$0.20 bet. The lowest bet is A$0.10, so a short first session can stay small.
The top prize is x25,000 the bet. On an A$0.50 bet that comes to A$12,500, and at the highest bet of A$500 it reaches A$12,500,000. A win of that size is never guaranteed, so size each bet for the losses you can afford.
