Greatest Catch Series
Mega Greatest Catch: Blue Marlin Slot Overview
A grumpy old angler in a wooden rowboat, a line in the water, and fish that carry cash on their backs. That is the Greatest Catch idea, and Blue Marlin is Evoplay's December 2025 rebuild of it.
The hook has not moved. Wilds turn up in free spins only, and when one shares the reels with a Fish it takes the value off every Fish showing, with a multiplier that climbs as more Wilds land. Everything worth having in this game lives inside that round, and the round stops dead at 10,000x total bet.
What is new is everything around it. The 2022 pair gave the base game nothing to do at all, while this build adds two rescue mechanics on the bonus symbols, a Wild that can conjure itself, an ante toggle and a buy menu. Same 5x4 grid, same 12 fixed lines, three years later.
Theme & Design
The game is cut in half at the waterline. Up top the angler sits in a wooden rowboat with his rod bent over the side and a red float bobbing beside it, green humpbacked islands behind him under a flat blue sky. Everything below is the reel area: deep water, kelp and pink anemones and a knuckle of yellow sponge crowding in from both edges, pale rounded rocks on the seabed.
The symbols are mostly tackle rather than sea life. A red toolbox stuffed with lures, a purple bucket hat with hooks pinned round the band, a blue rubber wading boot, one cheerful green turtle. Card ranks float inside soap bubbles with the letters in pink, green, red and blue. The Fish sits in a pale tile of its own with its value printed under it, and the Wild is the angler again, rod raised, his multiplier stamped in the top corner. Bright, clean, unmistakably a fishing cartoon, and drawn with more care than most of them.
Symbols & Paytable
| Symbol | Payout |
|---|---|
| Tackle box | 0.5x / 5x / 20x / 200x for 2/3/4/5Top payer, and the only symbol on the reels that pays from a pair |

Features & How They Work
Free Spins and the Fishing feature
Three, four or five buoys pay nothing in cash and hand over 10, 15 or 20 free spins instead. Wilds exist only in here. Land one alongside any Fish and it collects the value off every Fish on the reels, and if two Wilds land they each take the whole board rather than splitting it between them.
The round grows through Wilds, not through buoys. Every fourth Wild adds 10 more spins and lifts the collection multiplier, x2 after four, x3 after eight, x10 after twelve, each new batch played out after the one before it finishes. Buoys never appear during free spins, so there is no retrigger and the buoy progression is the only extension going. Longest possible round: 20 spins plus three batches of ten. Fifty, and you have to earn all of it.
Fish values run 2x, 5x, 10x, 15x, 20x, 25x, 50x, and then 2000x with nothing in between. The ceiling is absolute too. The moment a round touches 10,000x total bet it ends on the spot, the win is paid, and every remaining free spin is forfeited.
Random Wild and Dynamite
The Fishing feature needs two ingredients and this build protects both of them. Dynamite is the old one, firing after a losing free spin that has a Wild on the reels but no Fish, turning three to six regular symbols into Fish. Random Wild does the mirror image: at least one Fish sitting there with no Wild to collect it, and a non winning symbol has a chance to turn into one.
So whichever half is missing, something can supply it. The 2022 games only had the Dynamite half, which meant a Fish landing without a Wild was simply wasted, and nobody seems to have picked up on the difference. It is the smartest piece of work in the rebuild.
Respin Bonus and Random Bonus
Two buoys used to be worth nothing. Now two buoys start a respin: the reels holding a buoy nudge down one position while the rest spin again, and any wins landed during that respin are paid normally. One quirk to know about. If a buoy lands on the bottom row the respin does not happen, because that reel has nowhere left to nudge to.
Random Bonus runs alongside it and can drop an extra buoy onto a reel that does not already have one, any time two, three or four are showing. That is how a near miss becomes a trigger. It can also fire after a respin has ended, and respins stop as soon as there are enough buoys on the reels to open the free spins.
Bonus Chance, the ante that reads worse than it is
Flip the Bonus Chance switch and your stake goes up by half while the natural trigger rate doubles. The small print is where it gets uncomfortable: the higher amount comes out of your balance, but wins are still calculated on your original bet rather than the inflated one. Read that cold and it sounds like a straight tax.
It is not. The ante runs at 96.00% against a 96.02% base, two hundredths of a point, so the doubled trigger rate covers the extra stake almost exactly. It changes the shape of a session and not the price of one.
The buy menu, and why 312x is not the better buy
Two buttons in the shop: 68x total bet for free spins, 312x for Super Free Spins. The prices imply the expensive one is stronger. The returns say otherwise, 96.01% against 96.03%, which is 4.59 times the money for two hundredths of a point.
And you do not get more spins for it. Both buttons award a random 10, 15 or 20, the same lottery either way. The only thing 312x actually buys is a better chance of the 2000x Fish turning up, so it is a variance purchase, not a value one. Same expected return, same unknown length, completely different distribution. There is something faintly comic in it as well, since the Super option sells you a fish that the 10,000x ceiling cannot even pay out once at the top x10 multiplier.
The random round length deserves its own complaint. The 2022 Bonus Buy edition sold exact rounds, 45x for ten spins, 87x for fifteen, 137x for twenty. Here one flat 68x buys an unknown ten, fifteen or twenty, working out at 3.4x a spin if it lands well and 6.8x if it does not. Double the price for the same purchase, and the choice is made for you.

How Mega Greatest Catch: Blue Marlin Plays
Base game spins are quiet. Card ranks in bubbles, the odd pair of tackle boxes returning half a stake, and just under 17% of spins landing anything at all, the thinnest hit rate in the whole series. What you end up watching for is the second buoy, because two of them now means something is about to happen, and that one change gives the base game a pulse the 2022 versions never had.
Free spins run on a different clock. The spin counter matters less than the Wild count, since Wilds are what buy more spins and what raise the multiplier, so a round can feel finished at spin six or keep reopening itself three separate times. Most of them end in the first batch with a few small fish collected at no multiplier at all. Rounds that reach x3 are where it gets tense, and x10 is rare enough that getting there probably means the round was already going well.
Switch the ante on and the rhythm tightens: fewer dead stretches, shallower dips between bonuses (and yes, it is the same money, just spread out differently).
Pros & Cons
Pros
- Random Wild and Dynamite cover both halves of the Fishing feature, so a lone Fish or a lone Wild rarely goes to waste
- Respin Bonus and Random Bonus finally give the base game something to do at two bonus symbols
- The Bonus Chance ante costs almost nothing in return, 96.00% against a 96.02% base
- Clean split-level art with symbols that read instantly at a glance
Cons
- No Wild anywhere in the base game, so there are no substitutions until a bonus lands
- All five card ranks pay an identical 0.5x / 2.5x / 10x, and the bonus buoy pays no cash at any count
- The 312x Super buy costs 4.59 times the standard one for the same return and the same random round length
- Lowest hit rate of the five Greatest Catch games, at just under 17%
Is Mega Greatest Catch: Blue Marlin Worth Playing?
Three years is a long gap and Evoplay used it. The 2022 Mega Greatest Catch was a bonus round with a spin button attached; this one has a main game with mechanics of its own, a bonus that can manufacture its own missing half, and pricing on both the ante and the standard buy that is fairer than the marketing around them lets on.
The complaints hold up all the same. No Wild in the base game, five card ranks paying the same lazy amount, a bonus symbol worth nothing in cash, the lowest hit rate of the five Greatest Catch games, and a cap that can end the best round anyone has had here right in the middle of it. Written off as another cartoon fishing slot, it would have plenty of evidence stacked against it.
That reading skips what got rebuilt, though. Underneath the same grid and the same 10,000x ceiling as its 2022 siblings, this is the version where the design finally thinks about what happens when the reels do not cooperate.
