Playing it for the first time
Each spin lands symbols across five reels and three rows, and the fishing theme runs through the whole board. The base game uses 10 fixed paylines. Wins form when matching symbols land on a payline, counted from the leftmost reel to the right, and two matching symbols are enough. The symbol set includes a Monster pickup truck, a Dragonfly, a Tackle box and the card faces A, K and Q.
WILD and SCATTER symbols join the other symbols on the reels. Beyond the base game, the slot has Free Spins and Super Free Spins modes, which add their own rules. Money Collect and Progressive Multiplier complete its feature list, so this title offers more layers than the base game alone.

Five steps, one round
Round steps of Big Bass Splash 1000
After reading, you will know how one round moves from bet to session limit.
Smallest A$0.10, largest A$500
The reels stay still until you pick a bet between A$0.10 and A$500. Each spin takes that bet, and A$0.50 and A$10 are the example bets on this page.
Paylines from the leftmost reel
The reels pay from the leftmost reel to the right, along one of 10 fixed paylines on the 5 by 3 grid. Two matching symbols are enough to pay.
Big Bass Splash 1000 base symbols
On the reels, Wild and Scatter symbols join the paying symbols of the base game. Money Collect and Progressive Multiplier round out the features.
When the bonus screen takes over
Scatter symbols on the reels lead into the Free Spins mode, and Super Free Spins is the other bonus mode of this slot. The bonus screen replaces the base game.
Session limit before the first spin
Each spin ends with the reels stopping and your balance changing, so set a session limit before the first spin. No one can know in advance how a session ends.

Useful once a scatter lands, or before you pick a bet mode to see what each mode changes.
Big Bass Splash 1000 super round
The reels run Super Free Spins as a separate round, set apart from standard Free Spins. The game lists it as its own mode, alongside Base Game, Free Spins and the Ante Bet toggle.
Standard Free SpinsSuper Free Spins
Higher natural Free Spins chance
The reels carry more Scatter symbols when the Ante Bet toggle is on in the sidebar. The bet multiplier moves from 10x normal play to 20x, which gives a higher natural chance of Free Spins. RTP in this mode is 96.53%.

Pretend credits now, stakes later
The usual worry is losing money before the reels make sense.
The demo needs no money and pays nothing at all. The real game needs a U2win Casino account, and you must be 18 or older.
Play for realSetting realistic expectations for each session
Each spin lands symbols at random across the 5x3 grid, so no one can see in advance when the bonus round will come. How often it comes is not known before you play, and the result of one session is random whatever the RTP. Two sessions with the same bet can end in very different places.
Symbols pay left to right from the leftmost reel on 10 fixed paylines, and the RTP version running in this lobby sets the long-run return behind every spin. Which version is in use is shown only in the game rules, so read them before your first session.
Each round is decided by the random result on the reels, and the largest payout is a ceiling set against the bet, not a target a session works toward. The maximum win of Big Bass Splash 1000 is reached very rarely. Treat it as the top of the scale, never as the usual outcome of a session.

Quick answers on volatility, RTP, maximum win and free spins before you start.
How volatile is Big Bass Splash 1000?
Each spin on the 5x3 grid pays across ten fixed paylines, and the game sits at high volatility. Big wins arrive less often than small ones, with long quiet stretches between them. Nothing about the timing of a big win can be known in advance.
What is the RTP of Big Bass Splash 1000?
Every spin on the 5x3 reels follows one of three RTP versions: 96.51%, 96.52% and 96.53%. The base game runs at 96.52%, which means that share of all stakes returns to players over a very long run. A single session can land far above or below that figure.
How does Big Bass Splash 1000 differ from other Big Bass games?
Its reels pay up to 25,000 times the bet, while the other Big Bass titles in the series top out at 5,000 times. Splash 1000 also runs at 96.52%, slightly above the 96.50% and 96.51% of its siblings.
What is the maximum win on Big Bass Splash 1000?
Wins on the reels can reach 25,000 times the bet, which is A$250,000 at a bet of A$10. Higher bets scale that cap, so the top bet of A$500 would pay up to A$12,500,000.
How do I trigger free spins in Big Bass Splash 1000?
Scatter symbols that land on the reels lead into the Free Spins, and the game also has a Super Free Spins mode. How often that happens cannot be known in advance, so a session may pass without a single bonus round.
Can I try Big Bass Splash 1000 in demo mode before betting?
The reels follow the rules set out on this page, so the modes explain each outcome before any stake. Bets run from A$0.10 to A$500, and the paytable uses A$0.50 as its example.
