Mighty Fish™: Blue Marlin is an underwater video slot from Wazdan on a 5-reel grid with a theoretical RTP of 96.18%. A Collector symbol counts down while Cash and Jackpot icons land below it, and a wager can be multiplied up to 2,500x. Here are the specs, symbols and features before you play.

The action takes place beneath the waves, and the symbols are inspired by sea life: fish, corals and all kinds of sea creatures. The game plays on both desktop and mobile, and you can try the demo version first to get a feel for it before you deposit.

RTP is a theoretical, long-run figure, so it says nothing certain about a single session. Read more in our guide to what RTP means.

Symbols Found Underwater

  • Coin icons: pay out only in the Free Spins or Cash Out features.
  • Collector symbol: appears only on the top row, with a random countdown value from 1 to 10. Once triggered, it stays in place while the other reels keep spinning. With each round it gathers the values of all Cash and Jackpot icons that land on the reels below, until the countdown reaches zero.
  • Cash icons: carry prizes of 1x to 10x the initial wager. The jackpot icons are Mini with 20x, Minor with 50x, Major with 100x and Mega with 200x. Cash and Jackpot icons can only be activated through the Collector icon.

Special Features and Cash Out Modes

The slot uses some of Wazdan’s familiar mechanics:

  • Multiplier: multiplies the value of the prize by 2x to 10x.
  • Countdown Booster: raises the value of the Collector countdown by 3.
  • Collect to Infinity: sets the Collector countdown to infinity, so all the value from Cash and Jackpot icons is collected until the end of the Free Spins round.

There are also two Cash Out features. They show up on a random reel position and stay in play for up to 15 spins:

  • Cash Out: if a Cash, Mini, Minor, Major or Mega Jackpot icon is on the Cash Out label when the countdown reaches 0, the prize is paid out.
  • Trawler Cash Out: if a Cash, Mini, Minor, Major, Mega or Collector icon sits on the reel above the Trawler Cash Out sign when the counter hits 0, the matching payout is awarded.
