Mega Greatest Catch Slot Overview
Mega Greatest Catch is a pond fishing slot where fish swim past with cash values printed on them and one man in a rowboat sleeps through the whole thing. Everything worth having sits inside the free spins.
That is not a figure of speech. The Wild only exists in the bonus, so the base game runs twelve fixed paylines across a 5x4 grid with no substitute symbol of any kind, and the value fish that land there have nothing to collect them. Three or more Scatters change that. Wilds start dropping, and each one sweeps up the value of every fish on the board.
96.03% RTP, medium to high volatility, and a hit rate under one spin in five. It spends a lot of its time waiting.
Theme & Design
The waterline cuts the whole thing in half. Above it, a sunlit pond drawn in flat cartoon style: reeds crowding both banks, white lilies sitting on green pads, a small red-roofed cottage on the far shore, and a white-moustached fisherman in a yellow bucket hat sprawled back in a wooden rowboat with his red float bobbing on the surface. Below the line everything cools to teal, with kelp fronds swaying at the edges, gnarled tree roots gripping the right bank, and mossy rocks catching dappled light on the bottom.
There is no reel frame. Symbols hang in open water, which makes the grid feel like part of the pond instead of a box dropped on top of it. The symbols are the fisherman's kit and the pond's residents: a purple tackle pack with a thermos strapped on, a battered lace-up boot with hooks caught in the laces, that same yellow hat, and a green frog mid-leap. Card ranks are colour-coded letters floating inside soap bubbles. The Scatter is a golden fish on a violet disc with SCATTER curved above it, and the value fish are little blue ones towing a ribbon banner with the amount printed across it. Bright, well drawn, entirely unserious, and the fishing setup carries it further than the art alone would.

Features & How They Work
Free spins, and the Wild that only lives in them
Three, four or five Scatters award 10, 15 or 20 free spins. The Scatter pays nothing on top of that, not a coin at any count, so its entire job is the trigger. And it appears in the main game only, which has a consequence people miss: once the round starts the Scatter is off the reels, and free spins cannot be retriggered.
The Wild is the exact mirror. Any reel, but during free spins only, substituting everything except the Scatter. That one decision explains why the base game plays as flatly as it does.
The Fishing feature
When at least one Fish and at least one Wild land together in free spins, every Wild on the board collects the value of every Fish on the board. Not the nearest one, not the one sharing its payline. All of them. Two Wilds collect the whole board twice, three collect it three times, and that escalation is where the round's big numbers come from. It is a collect game once the bonus starts, and the twelve paylines become close to incidental.
The buoy bar and the fifty-spin ceiling
Every Wild that lands fills one buoy on a progress bar. Every fourth buoy awards 10 more free spins and lifts the Fishing multiplier: x2 after the first four, x3 after the second four, x10 after the third, which is the last tier there is. Those extra spins are played after the current batch finishes, so a good round arrives in stages rather than all at once.
Do the arithmetic and it gets interesting. Scatters cannot retrigger, so the buoy bar is the only way to extend a round, and it stops handing out spins after the twelfth buoy. Best case: 20 spins from five Scatters, plus three batches of 10. Fifty free spins, and not one more. That is a structural limit, not an estimate.
Dynamite
On any losing free spin where a Wild is on the reels but no Fish are, dynamite goes in the water and 3 to 6 regular symbols turn into Fish so the Wild has something to collect. Small thing, properly thought through, and it means a Wild almost never lands wasted.
The fish ladder, and the whale it cannot pay
Fish carry a random value drawn from a fixed set: 2, 5, 10, 15, 20, 25, 50 and 2000 times the bet. Read that ladder again. Seven values climbing politely up to 50, then one outlier forty times larger than the rung below it, with absolutely nothing in between. No 100, no 250, no 500, no 1000. Seven minnows and a whale.
Now hold it against the ceiling. The round is capped at 10,000x and the top Fishing multiplier is x10. A single 2000 fish collected once at x10 comes to 20,000x, double the entire cap. The game's best multiplier physically cannot be spent on its best fish.
And that cap is a hard stop rather than a theoretical maximum. If the free spins total reaches 10,000x, the round ends on the spot, the win is paid, and every remaining free spin is forfeited. Reaching the top of this game means having spins taken away from you.
Where it sits in the Greatest Catch family
Five of these exist and they all run the same engine. The Greatest Catch came first in April 2022 on 5x3 with 10 lines, then The Greatest Catch Bonus Buy a few weeks later. This one arrived in September on 5x4 with 12 lines, followed by Mega Greatest Catch Bonus Buy in November and Mega Greatest Catch Blue Marlin after that. Same buoys, same x2 / x3 / x10 progression, same Dynamite. This edition has no buy button, incidentally; that is the November release.
So Mega buys you a fourth row and two more paylines. It does not buy a bigger ceiling: all five stop at exactly 10,000x. The original 5x3 still holds the family's best base RTP at 96.09%, and its buy edition gives up 0.11 of a point for the button, which is the usual arrangement everywhere. Mega and Mega Bonus Buy both sit at 96.03% with no penalty at all, so somewhere between May and November 2022 Evoplay changed its mind about how to price a buy edition.

How Mega Greatest Catch Plays
The base game is thin and it knows it. Twelve fixed lines, no Wild, and five card ranks paying identically, which leaves a large slice of the reel set as interchangeable wallpaper. Under one hit in five, and most of those hits are letters in bubbles. The odd sensation is watching value fish drift onto the reels with amounts printed on their ribbons while nothing on the board is able to collect them. It looks like a feature. It is scenery.
Free spins flip the mood completely. The buoy bar gives the round a visible goal, which beats the hidden counters a lot of collect games run on, and there is a clear rising shape to it: fill four, get spins and a bump, fill four more, get another. The x10 tier feels like arriving somewhere. Most rounds finish long before it.
For my money the trouble is the gap between those two states. Base play asks for patience it does not really earn, and the payoff is a bonus that is good but boxed in at both ends, fifty spins and no more, 10,000x and no more. It can feel like a game carefully prevented from running away with itself.
Pros & Cons
Pros
- Every Wild collects the whole board, so two or three landing together escalates fast
- Dynamite means a Wild in free spins almost never goes to waste
- The buoy bar turns the round into a visible goal instead of a hidden counter
- Bright split-level pond art with no reel frame, symbols floating in open water
Cons
- No Wild anywhere in the base game, leaving twelve plain paylines with nothing to lift them
- All five card ranks pay the same 0.5x / 2.5x / 10x, so much of the reel set is filler
- The Scatter pays nothing at any count, three or five
- Hitting the 10,000x ceiling cancels the rest of your round instead of letting it finish
Is Mega Greatest Catch Worth Playing?
A likeable collect slot with one good idea executed properly and a base game that was clearly not the priority. The Fishing feature is strong, the buoy bar is a smart way to show progress, and Dynamite is the kind of small mercy more collect games should copy. Against that: no Wild outside the bonus, five identical card symbols, a Scatter worth nothing in cash, and a 19% hit rate that makes waiting for three Scatters feel long.
The maths has an oddity worth going in aware of. A value ladder that jumps from 50 straight to 2000 with nothing between, sitting under a cap that cannot accommodate its top rung even once at the highest multiplier, describes a game that pays out lumpily: plenty of modest rounds, an occasional excellent one, and a ceiling that arrives by ending things early. The extra row on the Mega version does not touch any of that.
