Introduction to Mega Greatest Catch Blue Marlin
Mega Greatest Catch Blue Marlin is a video slot from Evoplay, taking you on another fishing adventure in the company of a friendly angler, whose ambitions made him move from a quaint lake to the open sea. If you've made his acquaintance in The Greatest Catch Bonus Buy, a release from 2022, you know that despite enjoying frequent naps on his boat, he's also quite skilled in pulling fish with cash prizes from the water. This time around, there will be more opportunities for him to do so, thanks to the larger grid, which has grown from three to four rows high.
Join the fisherman and find out how he handles the new environment to reel in prizes worth up to 10,000x the bet, or practice first risk-free in the demo mode at the top of this page.
Theme, Gameplay & Payouts
Mega Greatest Catch Blue Marlin is a video slot from Evoplay with 5 reels, 4 rows, and 12 paylines. You can choose your stake from a range of options, starting from a Min.bet of 0.1, which makes the game particularly affordable, up to a Max.bet of 75. The math profile offers a default RTP of 96.02%, which is on the lower end of the industry average, but still promising reliable long-term returns. You can expect slightly more emphasis on the average value of wins rather than their frequency due to medium-high volatility, while the max payout available on any single round can reach 10,000x the bet.
The main scene in Mega Greatest Catch Blue Marlin is peaceful and picturesque. Most of the view remains submerged in clear blue water, showing us rock formations lining the ocean bed and a variety of aquatic flora decorating them. Above the surface, the fisherman's boat rocks on the gentle wave, making his nap all the more enjoyable, while solitary islands protrude from the water in the distance. The game is wrapped in a polished design full of vibrant colours and an upbeat soundtrack, which together create a pleasant, relaxed atmosphere. You can join the fisherman on his hunt for the legendary blue marlin on any modern device, whether you prefer to play on a desktop, a smartphone, or a tablet.
The paytable is divided into two groups of symbols, which award payouts whenever you match 3 of them (or 2, in the case of the top icon) on neighbouring reels, starting from the leftmost one. Each qualifying sequence must also cover any of the 12 active paylines. The low-paying icons are bubbles with traditional playing card royal emblems, including 10, J, Q, K, and A. They all award 10x the bet for matching 5 in a combination. Marlins in different sizes, a boot, a turtle, a bucket hat, and a tackle box represent the high-paying symbols. Those bring payouts ranging from 20x to 200x the bet when 5 combine on a payline. Reels will also hold Wilds in the form of the fisherman's image that substitutes for other icons and Bonus symbols depicted by a buoy.
Special Features & Slot Mechanics
What is the max win in the slot Mega Greatest Catch Blue Marlin?
You can win up to 10,000x the bet.
What features are available in the slot Mega Greatest Catch Blue Marlin?
The features are Fish Symbol, Random Bonus & Respin Bonus, Free Spins, and Feature Buy & Ante Bet.
Fish Symbol
Fish symbols appear in four different sizes, depending on the value of the prize they hold, which can be 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x the bet. These rewards can only be won during Free Spins, but fish symbols can also form independent paylines that award up to 20x the bet for a 5-of-a-kind sequence.
Random Bonus & Respin Bonus
Whenever you land 2, 3, or 4 Bonus symbols at the same time during a base game spin, a random event may bring more onto the screen to create or enhance the triggering combination.
When you land just 2 Bonus symbols in one spin, there's a chance to activate a respin that will give you another chance of landing more to trigger Free Spins.
Free Spins
With 3, 4, or 5 Bonus symbols on the grid simultaneously at the end of a base game spin, you'll trigger 10, 15, or 20 free spins, respectively. The fisherman symbol, which is a Wild, becomes active during this round, and it performs two roles. Firstly, it substitutes for all regular symbols to help create winning paylines. Secondly, it collects cash prizes from all Fish Symbols landing on the grid at the same time. Additionally, every Wild is collected in a progressive trail that awards retriggers and increased multipliers. Every fourth Wild accumulated there will award a new batch of 10 free spins, which is played after the current one is over, plus a multiplier of x2, x3, and x10 (for the first, second, and third retrigger) applied to all collected cash prizes during the respective batch.
When you have at least one Wild on the screen and no wins, there's a chance for the Dynamite feature to trigger and convert between 3 and 6 standard symbols into Fish Symbols. Also, if at least one Fish Symbol is present but there are no Wilds in view, any non-winning symbol may transform into a Wild.
Feature Buy & Ante Bet
The game offers the option for boosting your base game spins or triggering Free Spins instantly for a fixed buy-in that scales with your active bet.
1.5x = doubles the chance of triggering Free Spins.
60x = triggers 10, 15, or 20 Free Spins.
312x = triggers Super Free Spins, where the most valuable Fish Symbol, worth 2,000x the bet, appears more often.
Final Thoughts on Mega Greatest Catch Blue Marlin
Mega Greatest Catch Blue Marlin is a visually appealing online slot machine, albeit one without any standout qualities. By late 2025, the time we've written this review, most suppliers had released a game with a fishing theme based on mechanics from the old-school Fishin' Frenzy by Blueprint Gaming, later popularised by Big Bass Bonanza from Reel Kingdom, a Pragmatic Play partner. In this follow-up to The Greatest Catch Bonus Buy slot, Evoplay has created an eye-pleasing environment, although many of its elements, like low-paying symbols and the main scene's structure, have been reused from the previous production.
Gameplay-wise, this sequel follows the same rules as before, imitating the aforementioned titles from competitor studios, but this time on a grid expanded to four rows and with two additional paylines, and with two random events that may help you form or enhance your Free Spins triggering combination. These are hardly significant improvements compared to the previous release, especially considering the lack of any other changes and all the statistics being nearly identical, including the max win of 10,000x the bet. For those with deeper wallets, there's a new Feature Buy option, where the 2,000x Fish Symbol has a better chance to land.
Mega Greatest Catch Blue Marlin is a plain copy of the popular fishing slot format, way too late into the game to be noticeable among the sea of similar games.
