Meet Big Bass Splash 1000 on the reels
Five reels spin across three rows, and every symbol carries the fishing theme, from the monster pickup truck to the dragonfly and tackle box. Wins land on 10 fixed paylines. Symbols pay from left to right, starting on the leftmost reel, and two matching symbols in a row are enough for a win. It is a video slot built around that line-by-line mechanic.
Scatter and Wild symbols appear on the 5x3 reels, and the game adds Free Spins and Super Free Spins as bonus modes. Money Collect and Progressive Multiplier come on top of that set. Together, these names make up the features this slot adds to its base game.

Play guide
New to the reels? Start here
Mobo Casino shows each step in the order the reels run, before you place a bet.
Stake range from A$0.10
The reels sit idle until you pick a bet from A$0.10 up to A$500. Every payout follows that bet, and examples here use A$0.20, A$0.40 and A$2.
Big Bass Splash 1000 paylines
Symbols land on a 5x3 grid, and a win starts on the leftmost reel. Two or more matching symbols in a row from the left pay on any of 10 paylines.
Wilds, scatters, multipliers
The reels carry WILD and SCATTER symbols, plus Money Collect and Progressive Multiplier features. Each one shows up during play, so check the paytable before your first spin.
Free Spins entry on the reels
Enough SCATTER symbols on the reels start the Free Spins mode, and Super Free Spins is listed as a separate mode in this game.
Keep your session in check
The reels stop when you stop, so set your session limit before the first spin. Need support? Call the National Gambling Helpline on 1800 858 858.
Paying for a round up front
On the reels, the Free Spins buy costs 100 times the bet, or A$200 at the A$2 top example bet.
| Bonus round | Price | RTP |
|---|---|---|
| Free Spins bonus buy | x100 · A$200 | – |
| Super Free Spins bonus buy | x450 · A$900 | – |
Three paybacks, and the rules name one
Each spin on the reels takes the stake, and return to player is the share paid back over a long run, per A$100 staked. The game rules show the version Mobo Casino runs.
| Version | RTP | Shown as standard |
|---|---|---|
| Variant 1 | 96.53% | No |

Read this when a bonus is near and you want to know how it plays.
Big Bass Splash 1000 second bonus
On the 5 reels x 3 rows grid, Super Free Spins run as a separate bonus mode, listed apart from the standard Free Spins. Players reach it from the Base Game.

Move the sidebar toggle to 20x
More scatters sit on the reels when the sidebar toggle moves to the 20x setting. That gives a higher natural Free Spins chance than the 10x normal play. The RTP with this setting is 96.53%.

Can Big Bass Splash 1000 sessions be predicted?
Scatter symbols land on the reels at random, so Free Spins can start on the first spin or stay away for a long run of spins. How often that happens is not known in advance. The result of one session is random whatever the RTP, because the RTP is a long-run figure and not a promise for the next spin.
Symbols land across the 5x3 grid, and the paytable shows what each one pays for a bet of A$0.20. Which RTP version Mobo Casino runs is shown only in the game rules. Check those rules before you compare the three RTP figures on this page.
Wins on the reels can reach x25,000 the bet on Big Bass Splash 1000, and that ceiling is hit very rarely. The top figure marks the limit of the game, not a result any player can plan around. Keep each stake within what you can afford to lose.
When a losing run starts to hurt
Play is for players aged 18+. For support in Australia, call the National Gambling Helpline on 1800 858 858 or register with BetStop, the national self-exclusion register.
Spending limit first
Set a spending limit before the first spin and treat it as the most you can afford to lose.
Right after a win
Decide your stopping point before you start, and keep to it even after a win. A big win is no reason to keep spinning.
Have you set your limits?
Use the deposit and loss limits in your account before you add funds, so the cap is set before the reels start.
Big Bass Splash 1000 time-out
If the game stops being fun, take a break or self-exclude through BetStop. Winning or losing is no reason to start again straight away.

The base RTP of Big Bass Splash 1000 is 96.52%. Two other RTP versions exist, 96.51% and 96.53%, and the Ante Bet mode runs at 96.53%. RTP is the long-run return on total bets, so it says nothing about what one session will pay.
How do you trigger the free spins in Big Bass Splash 1000?
Scatter symbols start the Free Spins on the reels. The Ante Bet toggle in the sidebar raises the natural chance of Free Spins by putting more Scatters on the reels. No one can say in advance how often the bonus will come.
Can I buy the bonus in Big Bass Splash 1000?
Buy Free Spins costs A$200 at a A$2 bet, which is 100 times the bet. Super Free Spins cost A$900 at the same bet, 450 times the bet. Ante Bet mode disables Buy Free Spins.
What is the minimum and maximum bet on Big Bass Splash 1000?
Examples on this page use A$0.20, A$0.40 and A$2, but those are not the limits. The minimum bet is A$0.10 and the maximum is A$500 per spin.
How volatile is Big Bass Splash 1000 and what is its max win?
Big Bass Splash 1000 is high volatility, so wins can be large but come less often. The top win is 25,000 times the bet, which is A$50,000 at a A$2 bet. No one can know in advance how a session will go.
