Mega Greatest Catch Blue Marlin — slot review and demo

Marlin fishing with Gary

The slot takes you out to sea with fisherman Gary on a hunt for the legendary blue marlin. The action unfolds in turquoise waters where treasures lie hidden beneath the waves. The fishing theme is realised through a system of fish symbols with cash values and a collection mechanic — each wild symbol catches all fish on screen and adds their value to the round's win.

Progressive free spins and bonus mechanics

The core gameplay revolves around free spins with accumulating multipliers. Three, four or five bonus symbols trigger 10, 15 or 20 free spins. Every fourth wild symbol in free spins mode adds 10 extra spins and increases the fishing multiplier: ×2 after the first four wilds, ×3 after the next four, ×10 after the final four. The Bonus Buy feature lets you purchase regular free spins for ×68 bet or Super Free Spins for ×76 bet — in super mode the rare ×2000 fish symbol appears more often. Respin Bonus triggers with two bonus symbols: reels with bonuses shift down one position, the rest respin, giving a chance to land the third symbol. Random Bonus can randomly add a missing bonus symbol when two, three or four land.

Dynamite and random wilds

After a losing spin with a wild symbol but no fish, the Dynamite feature activates: 3–6 regular symbols turn into fish. If fish are on screen but no wilds, a random symbol can become wild and give an opportunity to collect a win.

Specifications and volatility

96.02% RTP, medium-high volatility, maximum win — €750,000. The slot suits players ready for periods without large payouts for the chance of a significant prize in free spins mode with multipliers. The full bet range is stated in the game rules at the operator. Other games by the studio can be found in the Evoplay slots catalogue.
