How To Play Big Bass Splash Online Slot

  1. To begin with, set your Bet starting from 10p up to £250.
  2. The Bet is calculated by multiplying the coins per line with the coin value. For example, 10 Pay Lines multiplied by 10p would equal a total wager of £1.
  3. After you’ve chosen your bet, you may spin the reels and keep an eye out for any winning combinations!

Symbols and Cluster Wins

Under the shimmering glow of sea creatures, vibrant animations, and swaying seaweed, the symbols transport you to an underwater party. To hook in a win, you'll need a minimum of 3 matching symbols swimming along the reels. The value of your catch will vary depending on the type of fish symbol and how frequently they school together on the payline.

All Pay Lines will pay from left to right across the reels. Any winning lines will be highlighted on screen and automatically added to your on-screen credit. You can only win once on each line but wins across several lines will be added together to form one brilliant prize!

Big Bass Splash Features

Wild Symbols: This cheerful bearded fisherman, which is only activated during the Free Spins mode, can act as a substitute for any other symbol in this game to create a winning combo, except for the Free Spins symbol. For example, if you had two Ace symbols next to each other, you’ll either need another Ace or a Wild symbol to complete a winning combo!

Scatter Symbol: If you land 3, 4 or 5 Fish symbols on the reels, you can win either 10, 15 or 20 Free Spins respectively! Free Spins mean you don’t use up any of your own credit, but once it’s over, you’ll go back to the main reels where you’ll use your own credit. If you only end up getting two Scatter symbols on a reel, it may randomly retrigger another spin or pull up a reel for the chance of getting a third Scatter symbol.

Money Symbol: These symbols, characterised by a fish and a random money value, can offer players a multiplier bonus during the Free Spins mode – all the way up to x5000 of a bet!
