Our verdict

0xPlaySlots opinion
6.8/ 10our score for this game

The four-level collection ladder that gives a round its shape arrives from the 2020 original unchanged, so the new machinery here is the modifier draw and the two-scatter helpers. That draw decides more about a round than anything the player does, which puts the most interesting part of the game outside the player's reach. The base game is thin enough that a session without a trigger is pure decay, and the buy is honestly priced at 100× for the same return as ordinary play. Competent and familiar rather than new but worth the time mainly for a round that draws well.

About Big Bass Splash

Big Bass Splash runs ten fixed lines on a 5×3 grid and its base game exists mainly to reach three scatters. Fish take a random money value on every spin, but nothing converts those values outside the free spins round because the collecting wild sits only on the feature strips. That makes the two-scatter helpers structural rather than decorative, since one nudges scatter reels down a position while the rest respin and the other hooks a reel upward to expose a third. Inside the round the maths is a wild count rather than a spin count. Every fourth wild collected adds 10 spins and lifts the collection multiplier from 1× to 2× and then to 3× and 10× before the ladder stops at the fourth level. Twelve collected wilds are needed to open the 10× band and by then the round has already been extended by 30 spins. The modifier draw separates one round from another, since START FROM LEVEL 2 deletes a quarter of the ladder and EXTRA FREE SPINS feeds every retrigger as well as the start. A round ends when the spins run out or when its total reaches the 5,000× cap that arrives about once in 3,086,876 spins.

Editorial takeaways

  • Ten fixed paylines pay from left to right on a 5×3 grid and each line stakes one tenth of the total bet.
  • Three, four or five scatters start 10, 15 or 20 free spins.
  • Every fourth wild collected adds 10 more spins and raises the collection multiplier to 2× and then 3× and 10× before the ladder stops.
  • A fisherman wild appears only during free spins, so the money values sitting on fish cannot be collected in the base game.
  • Free spins cost 100× the total bet to buy and return the same 96.71% as ordinary play in the default setting.
  • A round stops the instant its total reaches 5,000× the bet and that ceiling arrives about once in 3,086,876 spins.

Limitations and version notes

  • The base game is close to dead weight. Three royals return 0.2× the total bet, five fish return 20×, and the money values printed on those fish cannot be touched until the feature starts.
  • Casinos can run this game at several return settings and 94.60% is one of them. On a game that pays through one long bonus that gap is punishing, so the rules screen is worth opening first.
  • The modifier draw does more for a round than anything the player controls. A round that opens on level two with extra spins and a round drawn with nothing at all cost exactly the same.
  • Mechanically this is the series' original collection loop and its ladder is unchanged. A new monster truck sits at the top of the paytable, and the rest of the symbol set is the earlier games' equipment under new art.

Game mechanics

Ten fixed paylines

Base + bonus#01

Matching symbols land on adjacent reels from the leftmost reel on one of the ten lines.

The line pays its paytable value multiplied by the bet per line.

Nothing carries over to the next spin.

  • The bet per line is one tenth of the total bet.
  • Only the highest win on a line is paid.
  • Wins on separate lines are added together.
  • The ten lines are fixed and cannot be deselected.
  • Wins pay from left to right only.
  • Only the top symbol pays from two of a kind.

Money fish values

Base + bonus#02

Fish land on the reels on any spin.

Each fish takes a random money value that can be won during the free spins round.

A value stays on its fish while that symbol is on screen.

  • Possible values are 2×, 5×, 10×, 15×, 20×, 25×, 50×, 100×, 200×, 500×, 1666×, 2500× or 5000× the total bet.
  • A value is paid only when a fisherman wild collects it.
  • The fisherman exists only in free spins, so base-game values are never collected.
  • The same fish is also a line symbol worth 1×, 5× or 20× the total bet for three, four or five.

Fisherman wild collection

Bonus#03

A fisherman wild lands on any reel during the free spins round.

It substitutes for every symbol except the scatter and collects every money value showing on fish.

Each wild that lands is counted for the rest of the round.

  • Collected values are paid at the round's current collection multiplier.
  • The fisherman sits only on the free spins reel strips.
  • It has no line pay of its own.

Two-scatter nudging respin

Base game#04

Exactly two scatters land in the base game without a third.

The reels holding scatters move one position down while the other reels respin.

One respin, then the base game continues.

  • Awarded at random, not on every two-scatter spin.
  • Possible only when the scatters can move down one position without leaving the reel area.

Two-scatter hook

Base game#05

Exactly two scatters land in the base game without a third.

A hook pulls one of the reels up to reveal another scatter.

Nothing carries over to the next spin.

  • A random alternative to the nudging respin.
  • Neither event is guaranteed on a two-scatter spin.

Free spins modifiers

Bonus#06

Free spins are triggered and the game draws zero to five modifiers before the round starts.

Each drawn modifier changes how the round that follows plays.

The drawn modifiers apply for the whole round and its retriggers.

  • MORE FISH adds fish symbols to the feature strips.
  • MORE FISHERMEN adds wilds to the feature strips.
  • MORE HOOKS AND EXPLOSIONS raises the chance of the end-of-spin events.
  • START FROM LEVEL 2 opens the round on the 2× collection multiplier.
  • EXTRA FREE SPINS adds two spins at the start and two to every retrigger.
  • Zero modifiers is a possible draw and five is the maximum.
  • The draw is not player-selectable.

Wild collection ladder

Bonus#07

Every fourth wild collected during the free spins round.

The round retriggers with 10 more free spins and moves up one collection level.

The wild count and the level are kept for the whole round.

  • Level two collects at 2×, level three at 3× and level four at 10×.
  • The ladder stops after the fourth level, so a round retriggers three times at most.
  • Twelve collected wilds are needed to reach 10×, or eight when the round starts on level two.
  • The extra-spins modifier raises each retrigger from 10 spins to 12.
  • Retriggered spins are played after the current batch ends.

Dynamite, hook and bazooka events

Bonus#08

A free spin ends with fishermen but no fish, or with fish but no fisherman.

Dynamite adds money fish, a bazooka rewrites every symbol except the fishermen and a hook pulls a reel up to bring fishermen into view.

Each event resolves within its own spin.

  • Dynamite and the bazooka fire only when fishermen are on screen without fish.
  • The hook fires only when fish are on screen without a fisherman.
  • All three are random and none is guaranteed.
  • The hooks and explosions modifier raises their chance.

Special feature reels

Bonus#09

The free spins round begins.

The reels switch to dedicated strips that carry the fisherman wild in place of the scatter.

The feature strips are used for the whole round.

  • Two of the feature strips hold longer fish stacks for the extra-fish modifier.
  • The strips are not visible or selectable.

Maximum-win stop

Base + bonus#10

The total win of a free spins round reaches 5,000× the total bet.

The round ends at once and every remaining free spin is forfeited.

  • 5,000× the total bet is the ceiling for the whole game.
  • That ceiling arrives about once in 3,086,876 spins.

Progressive jackpot in jackpot versions

Base game#11

A base-game spin ends in a casino version that runs the jackpot module.

A pick screen reveals one of up to four progressive jackpots.

  • The tiers are GRAND, MEGA, MAJOR and MINOR.
  • Jackpots cannot be won during any feature.

Big Bass Splash bolts a lottery onto a fish ladder it never changed

The new parts sit outside the round

Big Bass Splash is the series' collection loop with a draw bolted to its front. Inside the free spins round, the fisherman wild, the money fish he collects and the four-level ladder that multiplies them all behave as the loop always has. What this entry adds sits before the round, in a draw of zero to five modifiers, or in the base game, in two helpers whose only purpose is to finish a scatter trigger. My reading is that the game has one pay event that matters, a wild collecting a fish, and that its most consequential new machinery decides how well that event is set up before the first free spin turns. None of that is in the player's hands, and it is the ceiling on my score.

Big Bass Bonanza is the original ten-line version of this loop, and Bigger Bass Bonanza had already reused its money fish and collecting fisherman. The entry that actually reworked the collector is the later Big Bass Rock and Roll, which splits the fisherman into two meters advancing independently. Splash leaves the engine alone and refines its edges: a monster truck at the top of the paytable, the familiar equipment symbols under new art, a nudge and a hook for two-scatter spins, and a modifier draw ahead of the feature. Anyone who knows the original already knows how a round here works. The only question worth asking is whether the edges change what a round is worth.

The paytable cannot pay for this game

I count five of the ten line symbols returning 0.2× the total bet for three of a kind, and three of those five top out at 5× for a full line. The fish pays 20× for five while also holding a money value that nothing in the base game can collect. The monster truck is the only symbol that pays from two, at 0.5×, and its 200× for five is the per-line ceiling. Ten fixed lines of it, which takes a screen of fifteen trucks, come to 2,000×. That is two fifths of the 5,000× cap from the most extreme board the paytable allows, so no base-game spin can reach the ceiling, and the only single event in the game large enough to cover it is a collection.

The base game has no wild and no multiplier. The money values sitting on its fish are prizes that expire when the reels stop. Its two-scatter helpers, the respin that nudges scatter reels down and the hook that pulls a reel up to expose a third scatter, are random and never guaranteed, yet they are the only base-game mechanics pointed at anything worth having. I treat the base game as the price of admission to the feature rather than as part of the game's appeal, because on these line values that is what it is.

That makes the return setting matter more than usual. At the default 96.71%, the game keeps 3.29 of every 100 staked. The reduced 95.67% setting keeps 4.33, and the 94.60% setting keeps 5.40, close to two thirds more than the default. On a game that pays through one feature, that gap separates a slow bleed from a fast one, and the rules screen shows which setting is running.

The fish values are the cap divided by the ladder

The thirteen money values run from 2× to 5,000×, and the top four are not arbitrary. Each is the cap divided by one collection level:

  • 5,000× collected at level one's 1× is the cap.
  • 2,500× collected at level two's 2× is the cap.
  • 1,666× collected at level three's 3× is 4,998×, the cap divided by three and rounded down.
  • 500× collected at level four's 10× is the cap.

The value table was built backwards from the ceiling, so at every rung of the ladder there is a fish that ends the round in one collection. The same arithmetic shows what the cap takes away. Because it stops the round at a 5,000× total and forfeits the remaining spins, the ladder's upside is flattened exactly where it grows. At 2× the top value already overshoots. At 3× the top two do. At 10× every value from 500× upward pays the identical capped amount, so 1,666×, 2,500× and 5,000× stop meaning anything at the one level where the multiplier is largest.

That largest step is the ladder's real prize. Level four's 10× is more than levels one to three combined, and more than triple the 3× below it. What it transforms is the middle and bottom of the value table: a 50× fish becomes 500×, a 100× fish becomes 1,000×, and the humblest 2× fish becomes 20×, the same as five fish on a line. A round lives or dies on reaching that band with spins left, which takes twelve collected wilds.

The cap is a smaller part of the maths than its prominence suggests. A 5,000× result once in 3,086,876 spins is worth about 0.16% of everything staked, roughly a sixth of one point of the 96.71% return. Nearly all of the return comes from rounds that finish below the ceiling, which is why the conditions a round starts under matter more than the headline number.

The draw decides more than the trigger does

Those conditions are drawn, not chosen. Two of the five modifiers change the ladder in ways I can count.

START FROM LEVEL 2 cuts the wilds needed for 10× from twelve to eight, a third fewer. A retrigger and a level-up are the same event, so the modifier also removes one of the three retriggers: a round that opens with 20 spins tops out at 40 instead of 50. It trades ten spins for a shorter road to the only multiplier that transforms mid-range fish, and I count that trade as favourable, since each wild collected before the top level pays one rung higher than it otherwise would. EXTRA FREE SPINS adds two at the start and two per retrigger, eight at most, so a 20-spin opening with three retriggers runs to 58 instead of 50.

The other three, MORE FISH, MORE FISHERMEN and MORE HOOKS AND EXPLOSIONS, raise the density of fish, of wilds and of the dynamite, hook and bazooka events that patch a spin showing fishermen without fish or fish without a fisherman. The trigger sets 10, 15 or 20 spins and the draw adds anything from no modifiers to all five, so a round opens with anywhere from 10 to 22 spins before a single wild lands, and only twelve collected wilds under EXTRA FREE SPINS carry a 20-spin opening as far as 58. The draw is the most interesting thing in the game, and I object to where it sits: it is variety handed down before the round, not a choice made inside it.

The buy is fair because the price ignores the draw

Buy Free Spins costs 100× the total bet and returns 96.71% in the default setting, the same as ordinary play. On average a buy hands back 96.71× and keeps 3.29×, the identical edge a spin charges, so there is no premium for skipping the base game. Its best case is the 5,000× cap, fifty times its own price. At the 250 top stake that is 25,000 per buy against a 1,250,000 ceiling.

The flat price is the honest part and the limiting part. A bought round that opens on 10 spins with nothing drawn costs exactly what a 20-spin round with START FROM LEVEL 2 and EXTRA FREE SPINS costs, so the 100× is fair only as a blend of good and bad draws. Nothing lets a player pay more for a better-set round or less for a worse one. Even so, for high stakes I rate the buy the best-designed element here: it turns the base game's thin line pays into a fixed entry fee with no markup, paid straight into the only part of the game that pays.

A good round, not a new one

This game suits players who already like the Big Bass collection loop, accept the pre-round draw as its source of variety, and buy features, since the buy costs nothing extra in return. Players who want the base game to hold up its end should look elsewhere, because on these line values it cannot. So should anyone at a casino running the 94.60% setting, and anyone who wants the collector itself to change, which is what the two meters of Big Bass Rock and Roll offer. Splash is a competent, well-priced repetition of a proven round, and its best-set rounds are decided by a draw rather than earned inside one.

Pros

  • The top fish values are tuned so every ladder level has one collection that reaches the cap
  • Buy Free Spins costs 100× with no return penalty against ordinary play
  • The 10× fourth level turns a 100× fish into a 1,000× collection
  • The two-scatter nudge and hook give a thin base game a real job

Cons

  • Five symbols pay 0.2× for three, and a full screen of trucks tops out at 2,000×
  • The modifier draw, not the player, sets a round's starting level and part of its spin count
  • The four-level collection ladder is unchanged from Big Bass Bonanza
  • At 10× the cap flattens the three largest fish values into one payout
  • The 94.60% setting keeps close to two thirds more per stake than the default

Verdict

A familiar collection ladder with a modifier draw bolted to its front, a thin base game and an honestly priced 100× buy. Competent rather than new, and worth the time mainly for a round that draws well.
