Our verdict

0xPlaySlots opinion
6.8/ 10our score for this game

Free Spins are well built, because Fish Money that sinks through the tumbles and an uncapped multiplier ladder give late Fishermen real weight. Around that round sit a thin base game and a Hold & Spin bonus that lives or dies on its opening coins. Both buys keep the full 96.70% return, which is fair pricing but adds no depth. One strong round in a weak frame earns a score in the competent band, just short of good.

About Big Bass Hold and Spinner Megaways

The base game is a tumble engine on up to 147,456 ways and its pays are small. Only the Fishing Float pays big at 50x for six while no other symbol pays more than 5x. Three extra rows above the middle four reels lock at random so the ways count swings from spin to spin. The Wild lands only in the topmost of those rows and works as an occasional helper rather than the engine. Free Spins carry the game because Fish Money worth up to 5000x total bet no longer tumbles away there. It sinks through the chain until a Fisherman collects it and every fourth Fisherman adds 10 spins at a higher multiplier. Dynamite and the Free Spins Mystery symbols both fire after the typical dead spin of a Fisherman with no fish to collect. Hold & Spin keeps only its starting coins and every new coin pays that held set again plus its own value. The opening coin total therefore sets the worth of every later hit, and a Diamond worth 50x to 2000x is the largest single value the round can add.

Editorial takeaways

  • The maximum win is 20,000x total bet, and the round ends the moment it is reached.
  • Buy Free Spins costs 100x total bet and Buy Hold & Spin costs 120x.
  • At the default setting both buys return 96.70%, the same as the base game.
  • The Fish Money multiplier has no cap of its own, since every retrigger after the third adds another x10.
  • Hold & Spin always pays at least 20x total bet, because respins keep coming until the round reaches that amount.
  • Six Fishing Floats pay 50x, which is ten times the best pay of any other symbol.

Limitations and version notes

  • The base game is thin, because every symbol except the Fishing Float pays 5x or less for a full six-reel way.
  • The x10 multiplier step needs twelve Fishermen in one round, and each raised multiplier waits until the current batch of spins has finished.
  • The 20x Hold & Spin minimum is a sixth of the 120x buy price, so the buy needs repeated coin hits or a Diamond to pay back.
  • Casinos can run this game at lower return settings down to 94.62%. The rules screen shows the one in use.

Top-row Wild

Base + bonus#02

A Wild can land only in the topmost extra row.

It substitutes for every symbol except Scatter, Fisherman and Coin Money.

The Wild has no payout of its own, so it only completes ways for other symbols.

Tumble feature

Base + bonus#03

Any winning combination on a spin or a tumble.

Winning symbols disappear and new symbols drop into the gaps at the same reel sizes.

Tumbles repeat until one produces no new win.

The whole chain is paid once the last tumble has played.

Fish Money symbol

Base + bonus#05

It lands as an ordinary paying symbol in the base game and in Free Spins.

It holds a random cash value that is paid only when a Fisherman collects it in Free Spins.

In Free Spins it survives every tumble of its spin and sinks to the bottom of the screen.

In the base game it tumbles away like any other symbol, and its cash value is never paid there. It also pays on ways like the other high symbols.

  • Lowest value 2x total bet
  • Values 2x, 5x, 10x, 15x, 20x, 25x, 50x and 5000x total bet

Fisherman collector

Bonus#06

A Fisherman lands in Free Spins on any position below the topmost row.

It collects the value of every Fish Money symbol on screen, times the current multiplier.

Each Fisherman counts toward the retrigger ladder until the round ends.

The Fisherman is a separate collector symbol, not the Wild. The Wild cannot stand in for it.

Fisherman retrigger ladder

Bonus#07

Every fourth Fisherman collected in Free Spins.

It adds 10 free spins and raises the multiplier on Fish Money collections.

The raised multiplier starts with the added spins, which play after the current batch ends.

  • 3rd retrigger x10
  • Each later retrigger adds x10
  • No limit on retriggers

Dynamite Fish Money drop

Bonus#08

At random, after a free spin that shows Fishermen but no Fish Money.

Mystery symbol

Base + bonus#09

Mystery symbols land at random in the base game, and in Free Spins they can follow a spin with Fishermen but no Fish Money.

This spin.

In Free Spins they turn into random symbols instead. That gives a Fisherman with nothing to collect another chance at Fish Money.

One well-built Fisherman round props up a thin base game and a Hold & Spin settled on its first screen

MJ

High Roller Expert at 0xPlaySlots

6.8/10

The Fisherman round is the game, and the rest is frame

I read this game as one good Free Spins round inside a frame that adds little to it, and the 20,000x cap is the cleanest way to show it. The paytable needs 400 six-Float ways in one tumble chain to reach that number. A bought Hold & Spin round needs at least ten later money symbols, every one of them a 2000x Diamond. Free Spins at the x10 step need one fish. Every section below follows from that gap.

The Fisherman loop itself is borrowed. Big Bass Bonanza is the original version: Fishermen collect Fish Money values, and every fourth one retriggers the round. Big Bass Bonanza Megaways runs it on Megaways reels with a higher multiplier at each retrigger, and Fishin’ Frenzy Megaways puts its own Fisherman collector on the same kind of reels. This game joins a crowded format rather than opening one, so it has to win on what it builds around a known loop. Inside the round it puts a tumble chain that Fish Money survives and a ladder that jumps to x10 on the third retrigger, and those two choices are the best things here. Outside the round it puts locking top rows and a Hold & Spin bonus, and neither pulls its weight.

The paytable is filler with one exception

Six Fishing Floats on one way pay 50x total bet, ten times the best pay of any other symbol. The Fishing Rod tops out at 5x for six. Below it I count eight symbols that pay 2.5x or less for a full six-reel way, and the Queen, Jack and Ten return exactly the stake. Against the cap, a six-Float way is one four-hundredth of 20,000x and a six-Rod way is one four-thousandth. The paytable reaches large numbers only by adding many ways together, up to 147,456 on a spin, and every locked position in the top rows cuts that count. With 20% of base spins returning a win, four in five return none. The Wild, confined to the topmost extra row and paying nothing itself, can only complete ways from this table.

The telling detail is Fish Money. On base spins the symbol that holds cash values up to 5000x is worth 1.5x for six of a kind, level with the Ace and the King, because its cash value is never paid outside Free Spins. Free Spins trigger once in 319 base spins on average, which is 319x total bet staked on this table per natural round.

Twelve Fishermen turn one fish into the cap

Fish Money runs 2x, 5x, 10x, 15x, 20x, 25x and 50x total bet, then jumps to 5000x. The top value is a hundred times the next one down, so the round works on two scales and the ladder decides which one counts. Collected before any raised multiplier applies, a 5000x fish is a quarter of the cap. At x2 it is half, and at x3 it is three quarters. At x10 it is 50,000x, two and a half times the cap, so the round ends at 20,000x and any spins still queued are forfeited. Each later retrigger adds another x10, so from the x10 batch onward one 5000x fish reaches the cap on its own.

The ordinary fish are where the ladder earns its keep. A 50x fish collected at x10 pays 500x, the value of ten six-Float ways from one symbol and one Fisherman. At x10, collections worth 2,000x at face value are enough for the cap on their own, and at x20, the fourth retrigger, 1,000x is enough. The multiplier has no ceiling of its own and the round does, so a deep ladder turns into the cap rather than into anything past it.

The price is the climb. The x10 step needs twelve Fishermen in one round, the first eight buy only x2 and x3, and each raised multiplier waits until the current batch of spins has finished, so the Fisherman who completes a step collects at the old one. Three details keep the climb honest. Every Fisherman counts toward the ladder until the round ends, including one that lands with nothing to collect. The empty Fisherman, the round's standard dead spin, has two answers: Dynamite can add Fish Money at random after such a spin, and Free Spins Mystery symbols can follow it and turn into random symbols for another chance at fish. And Fish Money survives every tumble of its spin and sinks to the bottom of the screen, so it waits for a Fisherman instead of tumbling away. Late Fishermen matter in this round, and it is the part of the game I rate highly.

Hold & Spin is settled on its first screen

A bought Hold & Spin round opens with three to six Coin Money symbols worth 1x to 30x total bet each, so the opening pays between 3x and 180x. Those starting coins are the only ones held for the whole round, and each later coin pays its own value plus the held set again. That held part of every later payout is fixed before the first respin, and it is sixty times larger from the best bought opening than from the worst.

From the worst opening, 3x, one later Coin Money adds at most 33x. Recovering the 120x price therefore takes at least four later coins even if all of them land at the 30x top value: the round stands at 102x after three and 135x after four. A 100x Diamond as the only later symbol leaves that round short of the price too. The 20x minimum guards the floor, and it is a sixth of the cost. From the best opening the round stands at 1.5 times its price before the first respin.

From a 180x opening, each later symbol adds at most 2,180x, which is a 2000x Diamond even if the held set pays again with it. Nine of those stop at 19,800x, so the cap takes at least ten. Free Spins at x10 need one fish. Hold & Spin reaches the cap on paper and stays the weaker half of the game, because nothing after the opening changes what the held set is worth.

Both buys are fair, and the cheaper one is the game

Both purchases return 96.70% at the default setting, the same as the base game, so neither charges a premium for skipping the wait. At that return the long-run cost is 3.30x total bet per Free Spins buy and 3.96x per Hold & Spin buy. Buying changes where the stake goes, not what it returns.

Buy Free Spins costs 100x and places 3 to 6 Scatters at random, so the round opens with 10 to 25 spins, a price of 10x down to 4x per opening spin. Its best case is the cap, 200 times the price, and it is the only buy in which a single symbol can reach the cap on its own. Against the natural route, 100x is under a third of the 319x staked on average between natural triggers.

Buy Hold & Spin's best case is about 167 times its 120x price. The extra 20x over the Free Spins price buys a floor, not a better ceiling, and the ceiling is what this game is for.

At the 240 top stake the two buys cost 24,000 and 28,800, both far above the largest single spin, and the cap pays 4,800,000. Casinos can run the game at 95.69% or 94.62%, and at the lowest setting the house edge is 5.38% against 3.30%, more than half as large again. The rules screen shows the setting in use.

It is a Free Spins game and should be chosen as one

Capped rounds come once in 1,496,522 spins on average, so the 20,000x cap supplies about 1.34 points of the 96.70% return, and the other 95.36 points come from rounds that stop short of it. At volatility 5 of 5 that return arrives unevenly, and the Fisherman round is where the game is decided.

It suits a player who wants the Big Bass Fisherman round with a deeper ladder and treats the base game as the cost of waiting, or skips it with the buy. A player who wants base spins with weight of their own should look elsewhere, and so should one who wants a coin round that grows as it goes, because this one's held set never grows after the opening. One well-built round in a thin frame earns a score in the competent band, just short of good, and that is where it sits.

Pros

  • Fish Money survives every tumble in Free Spins and sinks to wait for a Fisherman
  • The multiplier ladder has no ceiling, with x10 on the third retrigger and another x10 on each one after
  • Every Fisherman advances the ladder, even one with no fish to collect
  • From the x10 batch onward, one 5000x fish takes the round to the 20,000x cap
  • Both buys keep the full 96.70% return at the default setting

Cons

  • Past the 50x Fishing Float, no other symbol pays more than 5x for a six-reel way
  • The x10 step needs twelve Fishermen, and each raised multiplier waits for the current batch to end
  • Hold & Spin is settled by its opening coins, and its 20x floor is a sixth of the 120x buy
  • At the lowest 94.62% setting the house edge rises from 3.30% to 5.38%

Verdict

The Fisherman round is well built, with fish that wait through the tumbles and an uncapped ladder that lets one 5000x fish reach the cap from x10. A filler base game and a Hold & Spin settled on its first screen keep it in the competent band, just short of good.
