💧 Dive Into the Reef of Riches — Bubble Up! by Pragmatic Play
The ocean floor has never been this generous. Say hello to Bubble Up!, the vibrant new underwater money-collect slot by Pragmatic Play that combines a classic 6×6 grid with 40 fixed paylines, a full set of cash-value MONEY symbols, five fixed jackpot tiers (MINI, MINOR, MAJOR, GRAND and the mighty MAXI) and a genuinely original FRAME FEATURE that captures cash prizes inside expanding bubble frames of 2×2 all the way up to a full-screen 6×6.
Where most collect-style slots simply gather values on a single reel, Bubble Up! throws a glowing frame across a random area of the reels — and every pufferfish MONEY symbol trapped inside is added together and paid. Land a second overlapping frame and any MONEY symbols inside the shared area receive a multiplier of up to 10× on top of their printed value. Add a modifier-driven Free Spins round with a scatter-collection trail that expands the frame level by level, an Ante Bet, two Super Spin special bets, a Buy Feature priced at 100× total bet and a 10,000× max win, and you have one of the deepest high-volatility ocean slots Pragmatic Play has released.

🐙 The Legend of the Bubble Reef: Where the Octopus Guards the Sunken Idol
Deep beneath a shimmering tropical lagoon lies the Bubble Reef — a forgotten valley where a great stone idol sleeps half-buried in the sand. Legend among the fish says the idol once swallowed the treasure of a hundred sunken ships, and every coin it holds now rises slowly to the surface trapped inside glowing bubbles. Guarding it all is a cheerful pink octopus, who spends her days blowing enormous rings of light across the reef. Whenever one of her bubble rings settles over the coral, every plump pufferfish caught inside bursts open and spills its hidden fortune. The clownfish, seahorses and starfish have learned the rule of the reef: swim into the ring, and the treasure is yours. Take a breath — the bubbles are rising, and the reef is ready to pay.
📋 Bubble Up! Symbol Guide & Paytable — Values in Bet Multipliers
In Bubble Up! by Pragmatic Play, all symbols pay from left to right on adjacent reels starting from the leftmost reel across 40 fixed paylines. Only the highest win is paid per line, and wins on multiple paylines are added together. Below, every value is expressed as a multiplier of the total bet (×) rather than a cash amount, so the table applies at any stake level.
Standard Symbol Pays (6 / 5 / 4 / 3 of a Kind)
| Symbol | Tier | 6 of a Kind | 5 of a Kind | 4 of a Kind | 3 of a Kind |
|---|---|---|---|---|---|
| 🐠 Orange Clownfish | Top Premium | 25× | 10× | 5× | 1.5× |
| 🐟 Yellow Angelfish | Premium | 15× | 5× | 3× | 1.25× |
| 🐡 Pink Fish | Premium | 10× | 4× | 2.5× | 1× |
| 🐟 Green Fish | Premium | 7.5× | 3× | 2× | 0.75× |
| 🦄 Seahorse | Mid | 3.75× | 1.5× | 1× | 0.5× |
| 🦐 Shrimp | Mid | 3.75× | 1.5× | 1× | 0.5× |
| 🐚 Purple Shell | Low | 2.5× | 1.25× | 0.75× | 0.25× |
| 🐚 Blue Shell | Low | 2.5× | 1.25× | 0.75× | 0.25× |
| ⭐ Pink Starfish | Low | 2.5× | 1× | 0.5× | 0.25× |
| ⭐ Yellow Starfish | Low | 2.5× | 1× | 0.5× | 0.25× |
MONEY Symbol Line Pays (Pufferfish)
The pufferfish MONEY symbol is unique: it is the only symbol that pays from just 2 on a payline, and its line win is paid in addition to the cash values it carries.
| Match | 6 | 5 | 4 | 3 | 2 |
|---|---|---|---|---|---|
| 🐡 MONEY Pufferfish | 5× | 2.5× | 1.25× | 0.5× | 0.25× |
Special Symbols Explained
| Symbol | Type | Function |
|---|---|---|
| 🐡 Pufferfish | MONEY Symbol | Takes a random cash value on every spin. The value is won when the symbol is part of a winning combination or when it lands inside a frame. |
| ⚪ Pearl Bubble "FS" | Scatter | Appears on all reels. 3 / 4 / 5 / 6 scatters trigger the Free Spins feature with 1 / 2 / 3 / 4 modifiers. During the round, scatters also fill the collection trail. |
| 🔵 Bubble Frame | Feature Overlay | A 2×2, 3×3, 4×4, 5×5 or 6×6 frame that lands at a random position and pays the combined value of every MONEY symbol inside it. |
💰 MONEY Symbols & the Five Jackpot Tiers
On every single spin, each pufferfish MONEY symbol is assigned a random cash value drawn from a fixed ladder of 20 possible outcomes. Four of those values are the game's named jackpot tiers, displayed permanently above the reels along with the headline MAXI prize.
| MONEY Value (× base bet) | Jackpot Name |
|---|---|
| 0.5× · 1× · 1.5× · 2× · 2.5× · 3× · 4× · 5× | — Standard low values |
| 7.5× · 8× · 10× · 15× | — Standard mid values |
| 20× | 🔵 MINI |
| 40× | 🟢 MINOR |
| 80× | 🟣 MAJOR |
| 200× | 🟠 GRAND |
| 400× · 800× · 2,000× | — Ultra-high values |
| 10,000× | 🔴 MAXI (equals the max win cap) |
Key insight: because a single MONEY symbol can carry up to 10,000× base bet (MAXI), one perfectly placed frame capture can theoretically deliver the game's entire maximum win in a single moment — no long bonus grind required.
🔮 How to Play Bubble Up! — Complete Mechanics Guide
Bubble Up! by Pragmatic Play layers three systems on top of a traditional 40-payline engine: line wins, the Frame Feature cash collect, and a modifier-driven Free Spins round. Understanding how they interact is the key to reading the game.
1. Base Game — 6×6 Grid, 40 Fixed Paylines
The reels are a 6-reel by 6-row grid with 40 fixed paylines. Symbols pay left to right on adjacent reels from the leftmost reel, and 6-of-a- kind is the top combination. Only the highest win counts per line, and wins across multiple lines are added to the total. Free Spin (scatter) wins are added to payline wins.
2. The FRAME FEATURE — Bubble Up!'s Signature Mechanic
Randomly during any base game spin, a glowing frame of 2×2, 3×3, 4×4, 5×5 or 6×6 size appears at a random position on the screen. Every MONEY symbol that lands inside the frame has its value added together and paid, regardless of whether it forms part of a payline.
- Single frame: all MONEY values inside are summed and awarded.
- Second frame: also randomly, a second frame can appear on the same spin, doubling the capture area.
- Overlapping frames: when two frames overlap and MONEY symbols land in the shared area, those symbols receive a random multiplier of 2×, 3×, 5×, 8× or 10× applied to the value printed on the symbol.
The overlap zone is where Bubble Up! becomes explosive: a MAJOR-tier 80× MONEY symbol sitting in a 10×-multiplied overlap instantly becomes an 800× hit — and multiple symbols in that zone all receive the boost.
3. FREE SPINS — 6 Spins, Up to 4 Revealed Modifiers
Hit 3, 4, 5 or 6 scatter symbols anywhere on the reels to trigger the Free Spins feature and win 6 free spins with 1, 2, 3 or 4 modifiers respectively.
Before the round begins, eight coin items appear on screen. Click them to reveal modifier names until you match two of the same for each modifier awarded — those matched modifiers then apply to the entire upcoming round.
🎁 The Four Possible Modifiers
- MORE MONEY 🐡 — more MONEY symbols are present on the reel strips during the round
- MORE SCATTERS 🫧 — more scatter symbols are present on the reel strips during the round
- LEVEL UP 🔵 — the round starts with the frame already expanded to 3×3
- DUAL 🔵🔵 — two frames are guaranteed to appear on every free spin
📈 The Scatter Collection Trail
- At least one frame is guaranteed on every free spin
- Every scatter that hits is collected in a trail above the reels
- For every 3 scatters collected: the frame expands one level and +2 free spins are awarded
- Frame progression: 2×2 → 3×3 → 4×4 → 5×5 → 6×6 (max)
- Expansion applies from the next free spin; more than 3 scatters in one spin awards all corresponding upgrades
- Special reels are in play during the feature
The dream scenario is stacking DUAL + LEVEL UP with a long scatter run: two overlapping frames growing toward full-screen 6×6 coverage means nearly every MONEY symbol on the grid gets collected — with the overlap multiplier layered on top.
4. SPECIAL BETS — Ante Bet, Super Spin 1 & Super Spin 2
The Special Bets panel offers three alternative bet multipliers alongside normal play, each changing how the game behaves:
| Mode | Bet Multiplier | Effect | RTP |
|---|---|---|---|
| Normal Play | 1× total bet | Standard game — random frames, full Free Spins access | 96.52% |
| Ante Bet | 1.5× total bet | More power-ups during Free Spins: rounds won with Ante Bet on reveal 2, 3, 4 or 4 modifiers for 3, 4, 5 or 6 scatters hit — instead of 1, 2, 3 or 4 | 96.51% |
| Super Spin 1 | 20× total bet | One frame of random size is guaranteed at a random position on every base game spin. Scatters cannot hit and Free Spins cannot trigger | 96.51% |
| Super Spin 2 | 100× total bet | Two frames of random sizes are guaranteed at random positions on every base game spin — enabling overlap multipliers. Scatters cannot hit and Free Spins cannot trigger | 96.51% |
5. BUY FEATURE — Instant Free Spins for 100× Total Bet
Impatient reef explorers can skip the wait entirely. The Buy Feature button lets you pay 100× your total bet to instantly trigger the Free Spins round. When buying, 3 or more scatter symbols are guaranteed to hit randomly on the triggering spin — meaning you may be awarded more than the minimum single modifier if 4, 5 or 6 scatters land. The Buy Feature RTP is 96.51%, essentially identical to normal play.
6. MAX WIN — Capped at 10,000× Bet
The maximum win in Bubble Up! is limited to 10,000× the bet. If the total win of a Free Spins round reaches 10,000× bet, the round immediately ends, the capped win is awarded, and all remaining free spins are forfeited. Notably, the MAXI jackpot value on a single MONEY symbol is also 10,000× — the two figures are deliberately aligned.
❓ Bubble Up! Slot — Frequently Asked Questions
Who developed the Bubble Up! slot?
Bubble Up! was developed and published by Pragmatic Play. It is an underwater-themed, high-volatility money-collect video slot played on a 6×6 grid with 40 fixed paylines, featuring MONEY symbols, five fixed jackpot tiers, the Frame Feature and a modifier-based Free Spins round.
What is the RTP of Bubble Up!?
The theoretical RTP of Bubble Up! by Pragmatic Play is 96.52%. When using the Ante Bet, Super Spin 1, Super Spin 2 or Buy Free Spins options the RTP is 96.51% — a negligible difference, meaning no bet mode meaningfully disadvantages the player over the long run.
What is the maximum win in Bubble Up!?
The maximum win is capped at 10,000× the bet. If a Free Spins round's total win reaches 10,000× bet, the round immediately ends, the win is awarded and all remaining free spins are forfeited. The MAXI jackpot value that a single MONEY symbol can carry is also 10,000× base bet.
How does the Frame Feature work in Bubble Up!?
Randomly in the base game a frame sized 2×2, 3×3, 4×4, 5×5 or 6×6 appears at a random position. The values of all MONEY symbols inside the frame are added together and paid. A second frame can also appear on the same spin — and when two frames overlap, MONEY symbols in the overlapping area receive a random multiplier of 2×, 3×, 5×, 8× or 10× applied to their printed value.
What are the MONEY symbol values and jackpots?
Each pufferfish MONEY symbol takes a random value every spin from: 0.5×, 1×, 1.5×, 2×, 2.5×, 3×, 4×, 5×, 7.5×, 8×, 10×, 15×, 20× (MINI), 40× (MINOR), 80× (MAJOR), 200× (GRAND), 400×, 800×, 2,000× or 10,000× (MAXI) base bet. Values are won when the symbol forms part of a winning combination or lands inside a frame.
How do you trigger Free Spins in Bubble Up!?
Hit 3, 4, 5 or 6 scatter symbols anywhere on the reels to win 6 free spins with 1, 2, 3 or 4 modifiers respectively. Before the round, eight coin items appear — click them to reveal modifier names until you match two of the same for each modifier awarded. The matched modifiers then apply to the whole round.
What are the Free Spins modifiers in Bubble Up!?
There are four: MORE MONEY (more MONEY symbols on the reel strips), MORE SCATTERS (more scatters on the reel strips), LEVEL UP (the round begins with the frame already expanded to 3×3) and DUAL (two frames guaranteed on every free spin).
Can the free spins round be extended?
Yes. Every scatter that hits during the round is collected in a trail above the reels. For every 3 scatters collected, the frame expands one level (2×2 → 3×3 → 4×4 → 5×5 → up to 6×6) and 2 additional free spins are awarded. If more than 3 scatters land in a single spin, all corresponding upgrades are granted. Frame expansion applies from the next free spin onward.
Does Bubble Up! have an Ante Bet?
Yes. The Ante Bet uses a 1.5 total bet and delivers more power-ups during Free Spins: rounds won with Ante Bet active allow revealing 2, 3, 4 or 4 modifiers for 3, 4, 5 or 6 scatters hit, instead of the standard 1, 2, 3 or 4. Its RTP is 96.51%.
What is the difference between Super Spin 1 and Super Spin 2?
Super Spin 1 (20× bet multiplier) guarantees one frame of random size in a random position on every base game spin. Super Spin 2 (100× bet multiplier) guarantees two frames, which can overlap and trigger the 2×–10× MONEY multipliers. In both Super Spin modes, scatter symbols cannot hit and the Free Spins round cannot be triggered.
Can I buy the Free Spins in Bubble Up!?
Yes. The Buy Feature lets you pay 100× your total bet to instantly trigger the Free Spins round. When buying, 3 or more scatter symbols are guaranteed to hit randomly on the triggering spin, so you can be awarded more than one modifier. The Buy Feature RTP is 96.51%.
How volatile is Bubble Up!?
Pragmatic Play rates Bubble Up! as a high volatility slot. High volatility games pay out less often on average, but the chance of hitting big wins in a short time span is higher. Bankroll management and smaller stake sizing are recommended for extended sessions.
How many paylines does Bubble Up! have?
Bubble Up! uses 40 fixed paylines across a 6-reel, 6-row grid. All symbols pay from left to right on adjacent reels starting from the leftmost reel, only the highest win is paid per line, and wins on multiple paylines are added to the total win.
What are the minimum and maximum bets?
The minimum bet is $0.20 and the maximum bet is $24,000.00. Note that the base bet is the amount before feature-related increases — activating Ante Bet, Super Spin 1, Super Spin 2 or the Buy Feature multiplies the round's cost accordingly. Actual limits may vary by operator.
Is there a Bubble Up! demo and does it work on mobile?
Yes. A free-play Bubble Up! demo lets you explore the Frame Feature, jackpot tiers and modifier reveals without risking real funds. Built in HTML5 by Pragmatic Play, the game runs directly in any modern browser on iOS, Android, tablet and desktop with no download required — the 6×6 grid, frame animations and Buy Feature panel all scale to smaller screens.
🏆 Final Verdict — Is Bubble Up! Worth Diving Into?
Bubble Up! by Pragmatic Play takes the familiar cash- collect formula that has powered so many of the studio's biggest hits and gives it a genuinely fresh spatial twist. Instead of collecting values on a single reel or through a fisherman-style wild, the Frame Feature asks a different and far more exciting question on every spin: where will the bubble land, and how much of the grid will it swallow? That single design decision transforms the pace of the game, because a frame can arrive anywhere at any time and turn a dead spin into a jackpot moment.
The mathematical star of the show is the overlapping frame multiplier. When two frames intersect, MONEY symbols in the shared zone are boosted by up to 10× — and since individual MONEY symbols already scale all the way to the MAXI 10,000× tier through MINI (20×), MINOR (40×), MAJOR (80×) and GRAND (200×), the combinatorics get very serious very quickly. That the max win cap is set at exactly 10,000× the bet makes the ceiling clean and honest: one lucky capture really can end your session at the top.
The Free Spins round is where the design shows its depth. Six spins sounds modest until you realise that the scatter trail both expands the frame level and adds two more spins for every three scatters, meaning a hot round snowballs in two dimensions at once. Layer on the interactive coin-reveal for MORE MONEY, MORE SCATTERS, LEVEL UP and DUAL modifiers, and the anticipation begins before the first reel even spins — a smart piece of player psychology.
Flexibility is another strong suit. The Ante Bet at 1.5× is one of the better-value ante options in Pragmatic Play's catalogue because it upgrades the quality of the bonus rather than merely its frequency. Super Spin 1 (20×) and Super Spin 2 (100×) convert the game into a pure frame-capture machine for base-game purists and high rollers, while the Buy Feature at 100× total bet is an accessibly priced door straight into the modifier round. Crucially, RTP stays at 96.51–96.52% across every option.
Presentation is classic Pragmatic Play polish: sun-dappled water, a coral reef bursting with colour, a grinning pink octopus, a sunken stone idol and the reassuring glow of the five jackpot plaques above the reels. It is bright, friendly and instantly readable — the sort of art direction that welcomes casual players while the high volatility math keeps thrill-seekers engaged.
The verdict: Bubble Up! is a smart, well-engineered evolution of the money-collect genre. With five jackpot tiers, expanding and overlapping cash frames, four stackable free spins modifiers, an Ante Bet, two Super Spin modes, a Buy Feature and a 10,000× max win, Pragmatic Play has built an underwater slot with real strategic texture. Take a deep breath and let the bubbles rise — the reef is paying.
