    About Big Bass Double Down Deluxe

    Released in February 2023, Big Bass Double Down Deluxe is one of the many spin-offs of Pragmatic / Reel Kingdom's Big Bass series. What sets this variant apart is the Double Down feature, which can randomly double any active multiplier during free spins.

    The format is the familiar 5x3 grid with 10 paylines, with an official RTP of 96.5% (slightly below the Big Bass top-tier standard of 96.71%). Volatility is high. The max win reaches 5,000x your stake.

    The signature mechanics include the classic Big Bass Money Symbols collect (Cash Fish worth x1-x100 the stake, collected by the Fisherman wild), free spins of 10/15/20, cumulative x10 multipliers (x1 → x10 depending on the number of wilds collected), and the Double Down feature innovation, which can randomly trigger during free spins to instantly double the current multiplier.

    The Double Down feature is the standout selling point — on a lucky session where Double Down hits on a x5 multiplier (instantly becoming x10), big wins become more accessible than on the original Big Bass Bonanza.

    The visuals lean into a premium Big Bass look: deep-sea fishing with a giant bass, a premium fishing boat, and a blue-cyan-orange marine palette. A bonus buy is available at 100x the stake (not offered in the UK). Big Bass Double Down Deluxe is widely distributed across regulated and crypto-friendly casinos alike. For Big Bass fans looking for the Double Down variant with boosted multipliers, it's the logical pick. Also worth checking out: Big Bass Splash (enhanced Splash multipliers), Big Bass Hold & Spinner (a Hold & Win hybrid), and Big Bass Reel Repeat (the Reel Repeat feature).

    Key mechanics

    • Official RTP of 96.5%
    • Money Symbols collect (Cash Fish x1-x100 the stake)
    • Fisherman wild collector during free spins
    • Cumulative multipliers x1 → x10 cap
    • Double Down feature — randomly doubles the active multiplier
