The Big Bass Splash 1000 slot plunges you deep into a familiar underwater fishing adventure – think fishing boats, tackle boxes, fish, and tropical waters underpinning a high-stakes slot experience. The slot updates the formula of the prior Big Bass games by significantly boosting its win potential.

The aquatic theme remains central: colourful sea life, reels dripping with fish, rods and bait boxes, and an atmosphere that combines calm fishing vibes with high-volatility thrills.

Getting started is simple, but there are a few options to tailor your session:

• Preferred Spin Options: You can spin manually to savour each coin-value reveal, wild-collect animation and scatter drop or enable autoplay if you prefer more relaxed, continuous fishing.

• Bet Options: The betting range runs from 0.10 up to 250.00 coins per spin.

• Turbo Mode: The speed with which the reels turn move quickly when the turbo mode is triggered. 

The slot runs on a 5-reel x 3-row grid with 10 fixed paylines, and wins are formed via matching symbols on adjacent reels from leftmost. The base RTP is 96.52%, though alternate versions exist depending on operator. The volatility is rated very high, meaning payouts are infrequent but potentially very large. Max win rises up to 25,000x your bet.

• Low-value symbols are the standard card-royals (10, J, Q, K, A). 

• Higher-value symbols include themed icons such as rods, baits, tackle boxes, and jeeps/trucks. 

• There are also Money (Fish) symbols, Scatter symbols, and a Fisherman Wild (wild appears during Free Spins) that triggers collection mechanics.

• Money Symbols + Fish-Value Collecting: Fish-symbol icons carry a cash value between 2x and 1,000x your bet. However, these cash values are only realized if collected during the bonus phase in the base game they just act as regular payline symbols. 

• Free Spins Feature: Triggered by landing 3, 4, or 5 Scatter symbols anywhere on the grid. This grants 10, 15 or 20 free spins, respectively. Before the free spins begin, up to 5 random modifiers can be applied for example “More Fish”, “More Fishermen (Wilds)”, increased chance of random reel events (like dynamite, hook, bazooka), or starting already at a higher collection level. 
  
  • During Free Spins, the Fisherman Wild substitutes for regular symbols (except Scatter) and collects all visible fish-value symbols for a cash payout equal to their summed values. 
    
  • Additionally, for every 4 Fisherman Wilds collected within the Free Spins, the bonus round upgrades: you receive +10 extra spins, and the collection multiplier rises first x2, then x3, up to x10 (depending on how many wilds you collect). 
    
  • Random modifiers may still trigger during Free Spins (dynamite, hook, bazooka), adding fish, wilds, or rewrites to increase volatility and upside. 

Ante Bet & Feature Buy Options (Fast-Track Entry): If permitted by the operator, you can pay extra to boost the chance of entering Free Spins or skip straight to it. One option offers an Ante Bet (boosted bet to increase scatter frequency), while “Feature Buy” options include a standard Free Spins buy (for 100x the bet) or a “Super Free Spins” buy (for 450x the bet); the latter giving enhanced volatility / higher chance at top-value fish symbols. 

I find the Big Bass Splash 1000 slot to be a solid albeit familiar evolution of the Big Bass series. The underwater fishing theme is well executed, and the upgraded potential with a 25,000x max win, 96.52% RTP, and very high volatility makes it appealing for players chasing big wins rather than steady payouts.
