Mega Greatest Catch Blue Marlin Slot Review
A moustachioed angler in a red cap leans back in his rowing boat, rod bent double over a tropical bay, while below the waterline his line drops into a sunlit blue reef. Mega Greatest Catch Blue Marlin spends its base game trying to hand you the thing most fishing slots make you wait for: two Bonus symbols here are never quite a miss, because the reels will nudge, respin or conjure a third just to keep you close. It’s a generous design choice, and one some players will find more teasing than fun. Beneath the cheerful cartoon surface, Evoplay has built a mid-volatility chase where the scatters do most of the entertaining.
It’s a 5×4 grid with 12 fixed paylines, a 96.02% RTP, and a 10,000x maximum win that ends the free-spins round the moment it’s reached. Players who know Mega Duck Hunt or Piggy Bank: Coinstorm will recognise the family resemblance, with Fruit Fusion: Three Pots in the same catalogue. The bonus symbols decide everything here.
How the Base Game Pays
Wins form left to right across the 12 fixed paylines, and only the highest combination on each line counts. There are 10 regular symbols in total, running from a tackle box at the top down through the fisherman’s own gear to the royals, with the more expensive symbols paying the greater wins.
It’s the wild, appearing only in the free spins, that matches the tackle box as the richest symbol on the reels at up to 200x for five.
- Tackle Box: 0.5x for two, 5x for three, 20x for four, 200x for five
- Purple Hat: 3x for three, 15x for four, 100x for five
- Turtle and Blue Boot: 2x for three, 10x for four, 50x for five
- Blue Marlin: 1x for three, 5x for four, 20x for five
- A, K, Q, J and 10: 0.5x for three, 2.5x for four, 10x for five
- Wild: 5x for three, 20x for four, 200x for five
The tackle box is the only symbol that pays for two of a kind, so even a short line of the top icon returns something. Everything below it starts at three.
The Bonus symbol doesn’t pay anything itself. Its whole job is landing often enough to tip the game into its free-spins round, and most of the base-game entertainment comes from the two features that exist to help it do exactly that.
Random Bonus and Respin Bonus
Respin Bonus
When two Bonus symbols land, the Respin Bonus can start, provided neither of them sits on the bottom row. A Bonus symbol already resting on the bottom row can’t nudge anywhere, so that configuration simply doesn’t qualify. When the feature does run, the reels holding the Bonus symbols nudge down one position while the other reels spin again, and any wins during the respin are paid as normal.
It’s a small piece of theatre with a clear purpose: another shot at the third scatter. If enough Bonus symbols arrive to trigger the free spins, the respins stop immediately and the bonus begins. If not, the game carries on.
Random Bonus
The Random Bonus can fire at any point in the main game when two, three or four Bonus symbols are already on screen. An extra Bonus symbol appears by random event, landing only on reels that don’t already hold one. It can also trigger after a respin, so a two-scatter spin can escalate fast: nudge, respin, then a random addition.
Neither feature is guaranteed, and neither pays anything on its own. Both exist to close the gap between two Bonus symbols and three, which is where the real game starts.
Free Spins and the Fishing Feature
Three Bonus symbols award 10 free spins, four award 15 and five award 20. Bonus symbols only appear in the main game, so the round can’t be retriggered the usual way. Everything that happens inside it runs through two symbols that don’t exist anywhere else in the game: the Wild and the Fish.
- 3 Bonus symbols: 10 free spins
- 4 Bonus symbols: 15 free spins
- 5 Bonus symbols: 20 free spins
The Fishing Feature
During free spins, Fish symbols carry random values of 2, 5, 10, 15, 20, 25, 50 or 2,000x the bet level. When one or more Fish symbols and at least one Wild land at the same time, the Fishing feature triggers. Every Wild on the reels collects the values of all the Fish symbols on screen, and the payout is added to any regular winning combinations from the same spin.
Multiple Wilds each collect the full amount, so a spin with two Wilds and three Fish symbols pays the combined Fish values twice. That’s where the round’s real potential sits.
Two rescue features keep the round from going quiet. After any losing spin that shows a Wild but no Fish symbols, the Dynamite feature can replace three to six regular symbols with Fish symbols, instantly creating something worth collecting. And when Fish symbols are on the reels but no Wilds, a Random Wild can turn a non-winning symbol into a Wild. Between them, most spins inside the round have a route to a collection.
Wild Milestones
Every fourth Wild that lands during the round awards 10 additional free spins with an increased multiplier for the Fishing feature. The first four Wilds bring a x2 multiplier, the second four bring x3, and the third four bring x10, which is the final batch of additional spins.
The new spins play after the current batch finishes, so the round steps up in stages rather than mixing multipliers mid-run. A spin within a x2 batch collects at x2; once those spins are spent, the x3 batch begins on any collections that land inside it.
That ladder is the whole shape of the bonus. A round that stalls on Wilds stays modest; one that keeps landing them builds towards a x10 collection with 2,000x Fish values in play, and that’s the arithmetic behind the 10,000x cap, which ends the round immediately when reached with any remaining spins forfeited.
Bonus Buy
A Bonus Buy button sits in the interface, letting players go straight to the free-spins round rather than waiting on the scatter chase. There’s also a Bonus Chance option, though its pricing and mechanics aren’t detailed in the game’s rules.
Anyone using the buy should check the cost against their balance before committing, as with any purchase feature.
Our Honest Verdict
Overall Rating: 7.2/10
This is a slot that keeps dangling the fish just under the surface. Two Bonus symbols is the game’s favourite position, and the nudges, respins and random additions built around it mean most spins feel like they’re going somewhere even when they pay nothing. That’s the reason to pick it: the chase itself is the entertainment, and the angler’s grin barely ever leaves the screen.
The free-spins round is the best thing here, because the Wild ladder gives it a shape most collection bonuses lack – a round either builds or it doesn’t, and you always know which one you’re in. The weakness is that everything hangs on the bonus. The base paytable is thin, and a round that never finds its Wilds fizzles out well before the 10,000x cap is ever in sight.
It suits players who enjoy the near-miss tension of a scatter hunt and don’t mind modest paylines while they wait. Anyone chasing big base-game hits will find the bay quiet between bonuses. For patient anglers, though, there’s plenty biting below the waterline.
