Mega Greatest Catch Bonus Buy Slot Overview
A cartoon pond, a fisherman asleep in his rowboat, and fish drifting past with cash values printed on ribbons beneath them. Same game as the non-buy Mega release, minus nothing, plus one orange tab on the left rail.
Everything lives in the free spins. The Wild only shows up there, so the base reels run twelve fixed lines across 5x4 with no substitute symbol at all, and the value fish that land in the main game have nothing to collect them. Three Scatters open the round. Wilds start dropping, each one sweeps every fish value off the board, and a buoy bar keeps score while handing out more spins at bigger multipliers.
Which makes the orange tab the interesting part, and the pricing behind it is the most carefully thought-through thing in the game. 45x, 87x and 137x of the total bet for 10, 15 and 20 spins. It runs the opposite way to almost every buy menu you have used.
Theme & Design
The waterline splits the picture in two and the game plays out below it. Above, flat sunlit cartoon: reeds crowding both banks, white lilies on their pads, a red-roofed cottage on the far shore, and an old boy in a yellow bucket hat stretched out in a wooden rowboat with his rod arcing overhead and a red float sitting dead still on the water (he never stirs, whatever happens underneath him). Below, the colour drops to deep teal, kelp sways at the edges, and gnarled tree roots grip the right bank above mossy stones.
There is no reel frame, so symbols hang loose in open water. A boot with hooks caught in the laces, a purple backpack with a thermos strapped on, that same yellow hat, a green frog mid-leap, card ranks glowing inside soap bubbles, and the little blue value fish towing ribbons with their amounts written across them. Wins draw blue lightning between the symbols and throw the total across the reels in fat gold numerals. The orange BONUS BUY tab sits pinned to the left edge the whole time, which is presumably the point of an underwater setting this uncluttered.

Features & How They Work
The buy menu, and why it is shaped the way it is
Three tiers: 10 free spins for 45x the total bet, 15 for 87x, 20 for 137x. Divide through and the shape jumps out. 4.50x per free spin at the bottom, 5.80x in the middle, 6.85x at the top. Buying in bulk costs more per spin, over 50% more at the top tier than the bottom. Almost every bonus buy menu in the business is either flat or discounts the bigger packages. This one charges a premium for them.
And the return climbs alongside the price: 95.60%, then 96.00%, then 96.27%, against a base game of 96.03%. So the 20-spin purchase is the only option in the whole game that returns more than ordinary spinning, and the 10-spin purchase sits 0.43 of a point below base, easily the worst way to play. Two thirds of a percentage point separate the cheapest tier from the dearest. For a buy menu that is a chasm.
The buoy bar explains it. Value in this game does not scale with round length, it accelerates with it, because spins and multiplier tiers are earned by piling up Wilds across the whole round rather than within any one spin. Every tier reached pays twice over, ten more spins and a bigger multiplier on everything collected after it. A 20-spin round reaches the eighth and twelfth buoy far more often than a 10-spin round does, so it is worth considerably more than twice as much. A price that rises faster than the spin count, and an RTP that rises with it, are both the mathematically correct answer to that.
Set it beside Massive Luck Bonus Buy, another Evoplay title, where all three tiers cost exactly 3.2x per spin and all three carry an identical RTP. Nothing escalates in that game, nothing carries between spins, so a spin is worth what a spin is worth and flat pricing is right. Two menus from the same studio, two opposite shapes, each one correct for the game underneath it. Somebody actually did the work.
One detail that matters to the sums: the Scatter pays no cash, so a purchase buys a trigger and nothing else. There is no instant win folded into the price to net off against it. Those per-spin figures are the whole cost.
Free spins, and a Wild that only exists inside them
Three, four or five Scatters award 10, 15 or 20 free spins, and that is the Scatter's entire job. It pays nothing at any count and lands in the main game only, so once a round begins there are no Scatters left on the reels and nothing retriggers.
The Wild is the mirror image: free spins only, any reel, substituting everything except the Scatter. Every Wild that lands also fills one buoy on the bar, and every fourth buoy adds 10 free spins and lifts the Fishing multiplier. x2 after four buoys, x3 after eight, x10 after twelve, and twelve is where it stops. Extra spins queue behind the current batch. Since the bar is the only way to stretch a round, the longest one the game can produce is 50 spins: 20 from five Scatters plus three batches of ten, and not one more.
Fishing and Dynamite
Land at least one Fish and at least one Wild together in free spins and every Wild collects the value of every Fish on the board. All of them, not just the ones sharing its line, and two Wilds sweep the full board twice over. Dynamite handles the near miss: on a losing free spin with a Wild present but no Fish, 3 to 6 ordinary symbols are swapped for Fish so the Wild has something to pull in. Small idea, well judged, and it means a Wild almost never lands wasted.
Fish values and the ceiling above them
Fish are worth 2, 5, 10, 15, 20, 25, 50 or 2000 times the bet. Seven sensible rungs, then a jump of forty times with absolutely nothing in between. Above all of it sits a hard cap of 10,000x the total bet, and reaching it ends the round on the spot, pays the win and forfeits whatever free spins were left.
The other Mega, and the button Evoplay stopped charging for
Mega Greatest Catch is this game without the menu, out twelve weeks earlier. Both run 96.03% on ordinary spins, so choosing this edition costs nothing at all. That is not how it usually goes. The earlier 5x3 pair shows the normal arrangement: The Greatest Catch Bonus Buy gives up 0.11 of a point, 95.98% against the original's 96.09%, in exchange for the button. Somewhere between May and November 2022 Evoplay quietly stopped billing for it.
Five games sit on this engine now, same buoys, same x2 / x3 / x10 climb, all capped at exactly 10,000x. Mega buys a fourth row and two extra paylines. It does not buy a higher ceiling.

How Mega Greatest Catch Bonus Buy Plays
Bought or waited for, the free spins are the game, and the difference between those two routes is patience. A 19% hit rate with no Wild on the reels means long stretches of card letters returning half a stake, and five of those card symbols pay exactly the same, so even the wins blur together. It is thin going. The menu converts that wait into a decision, which is a better use of an evening whether or not the money lands the same way.
A bought round has a rhythm the base game never comes close to. Buoys light one at a time, the bar creeps, and the moment the fourth one fills the round stops being a countdown and turns into a project: ten more spins, a bigger multiplier, a reason to care about reaching the eighth. Rounds that stall on two or three buoys are flat and finish quickly. Rounds that reach the third tier can feel like a different game.
The odd part is how a great round ends. Hit the cap and there is no build, no finish, just a hard stop with spins still on the counter.
Pros & Cons
Pros
- The 20-spin purchase at 96.27% returns more than the base game, which almost no buy menu manages
- Buy pricing is built around how the buoy bar actually escalates, not picked off a shelf
- Dynamite stops a Wild landing with nothing to collect, and multiple Wilds each sweep the whole board
- No RTP penalty for taking this edition over the plain Mega release
Cons
- The 45x tier is poor value, 0.43 of a point below base for a round too short to climb the bar
- Base game has no Wild whatsoever and five card symbols paying identically, so it plays thin
- The Scatter pays nothing, so every purchase is a straight cost with no instant win against it
- The 10,000x cap cuts a strong round off early rather than letting it run out
Is Mega Greatest Catch Bonus Buy Worth Playing?
Buy the 20. It is the only purchase here that returns more than spinning normally, it starts the round at the longest length the game can naturally reach, and it gives the buoy bar the room it needs to get to the tiers that matter. Everything below it buys a shorter round at a worse rate.
What 137x will not fix is the game underneath it. No Wild in the base reels, five identical card symbols, a hit rate under one spin in five, and a menu on the left rail changes none of that. For my money the fishing round is good enough to carry it anyway, mostly because the buoy bar gives a bonus a visible goal instead of a countdown, and the collect escalates properly once two or three Wilds start landing together. The pricing was worked out by someone who understood their own maths, and that is rarer than it should be.
