Bubblin' Riches

Bubblin’ Riches is an underwater slot from Play’n GO, released on 15 October 2025. It plays on a 6x4 grid with 4,096 ways, returns 96.2% at high volatility and takes bets from 0.10 to 100. The top prize is 10,000x the bet, and the route there runs through a reward spins round with a multiplier that climbs into double figures.

A Sunlit Reef

The reels sit in a pane of clear water with shafts of sunlight coming down from above, purple and green coral along the bottom of the screen and bubbles drifting up past the grid. A cheerful goldfish wearing a gold crown hovers above the frame as the game’s mascot, and the BUBBLIN’ RICHES logo sits beside him.

The symbols are a small shoal – an orange fish, a purple fish, a green fish and a blue fish – with A, K, Q, J and 10 in bright bubble lettering underneath.

Six Reels, Four Rows, 4,096 Ways

The arithmetic is exact and worth doing once. Six reels of four symbols each is 4 x 4 x 4 x 4 x 4 x 4 – 4,096, precisely the figure on the data sheet. Symbols pay from the left on adjacent reels regardless of which row they land in.

Because there are six reels rather than five, the paytable runs to six of a kind, and that top band is where the real values sit.

The Paytable

The values are printed at your selected stake. At a bet of 20.00, for six, five, four and three of a kind:

Orange fish – 100.00 / 60.00 / 40.00 / 20.00
Purple fish – 100.00 / 60.00 / 36.00 / 20.00
Green fish and blue fish – 60.00 / 40.00 / 30.00 / 14.00
A and K – 28.00 / 20.00 / 10-12.00 / 6.00
Q, J and 10 – 20.00 / 12.00 / 6-8.00 / 6.00

Six orange fish on one way are worth 5x the bet, and three of the same fish return the stake exactly. Those are modest numbers, as they must be – with 4,096 ways, a single spin can pay dozens of them at once.

The Game Counts The Ways

Every win is labelled with its amount and the number of ways behind it. Our quietest spin read “28.00 – 2 WAYS WON” at a 20.00 bet – 1.4x the stake from two paths of blue fish.

That is the honest shape of the base game on a ways engine with a flat paytable: frequent, small, and entirely dependent on how many paths happen to line up.

Reward Spins And A x8 Multiplier

The round that matters puts two plaques above the grid. On the left, MULTIPLIER X8; on the right, REWARD SPINS 23/25.

Twenty-five spins is a long round by any standard, and the multiplier is a flat eight times applied to the whole spin. The effect is immediate: a win labelled “96.00 – 1 WAY WON” produced a total of 272.00 at a 20.00 bet – 13.6x the stake from a single path, which would have been worth a fraction of that in the base game.

Slot catalogues list additional free spins, a random multiplier, respins and an additive symbol alongside the round, so the eight on that plaque is a value the round has climbed to rather than a fixed setting.

The Bubble Board

A second feature clears the fish away entirely. The grid becomes a field of small bubbles, and golden shells land among them – ours filled the corners and the right-hand side, with the banner reading “Won 300.00” at a 20.00 bet, or 15x.

The catalogues confirm a bonus game and a bonus wheel in the feature set, and the empty-bubble layout is the standard visual language for a hold-and-collect round: only the shells stay, and the board is worth what it gathers.

The Mini Plaque

A small badge sits in the top right corner of the frame throughout the base game reading MINI 20X. That is a fixed prize expressed as a bet multiple rather than a cash amount – 20 times whatever you are staking – and it is the lowest rung of the game’s prize structure.

Expressing it as a multiple rather than a currency figure is the sensible choice, because it means the plaque reads the same whether you are betting ten or a hundred.

The Two Top Fish Are Nearly Identical

A detail that makes the paytable easier to hold in your head: the orange and purple fish pay the same for six, five and three of a kind, and differ only at four – 40.00 against 36.00. The green and blue fish below them are identical at every band.

In other words there are really only three tiers of fish rather than four, and three tiers of letters. On a 4,096-way grid that simplicity is welcome: you are not trying to work out which of eight similar symbols just paid, only which band it belonged to.

Why Six Reels Changes The Feel

Most ways games use five reels, and the sixth here does two things. It adds a whole extra band to the paytable – six of a kind, worth roughly half as much again as five – and it quadruples the way count compared with a five-reel version of the same grid.

The practical consequence is that near misses feel different. On a five-reel game a symbol landing on the first four reels is one away from the top prize; here it is two, and the difference between a 60.00 result and a 100.00 one is a single extra fish on the sixth reel.

Watch The RTP Version

Play’n GO ships this game in several RTP versions, and the catalogues flag it as a range rather than a single number. The 96.2% quoted here is the headline setting; your casino may be running a lower one. The reels, the reward spins and the bubble board are identical either way, so the game rules screen inside the casino is the place to check.

What The Bet Changes

Everything scales with the stake, and the selector under the grid offers five fixed steps – 10.00, 20.00, 40.00, 50.00 and 100.00. Our screenshots were taken at 20.00. At the 0.10 minimum six orange fish pay 50 cents and the Mini is worth 2.00; at the 100 maximum six fish pay 500 and the Mini 2,000. The multiples – 5x, 20x, 10,000x – do not move.

More From Play’n GO

Reactoonz 100 arrived the day after this one and uses clusters instead of ways, Cursed Moon Power Collection builds its multiplier through a level meter on a 1,024-way grid, and Static Nightmare Abyssways grows its reels all the way to 46,656 ways.

Who It Is For

Bubblin’ Riches is for players who like ways games and long bonus rounds. The base game is gentle to the point of being uneventful – 1.4x for two ways is typical – but twenty-five reward spins running at a x8 multiplier is a genuinely substantial feature, and the bubble board gives the game a second string. A 96.2% return is respectable, high volatility means the wait is real, and the artwork is bright enough to make the wait pleasant. All six casinos we checked carry it.
