Bubble Up!: Frames, Pearls and 10,000x Money

Bubble Up! is an underwater slot from Pragmatic Play where the real action happens inside bubble frames. Money symbols pay when a frame lands around them, and the best results come when frames overlap.

Pragmatic Play lists the RTP at 96.52%. The provider page does not give a volatility rating, a grid size or an overall maximum win, so those are left out. The largest figure the provider does quote is for money symbols, which can carry values of up to 10,000x.

Standard wins come from matching three to six sea creatures, which award instant prizes. Money symbols that feature in winning combinations are the other source of value, and the frames decide how much of that value reaches your balance.

Bubble frames are the core mechanic and they appear in both the base game and the bonus. Each frame lands on random grid positions and can be anything from 2×2 up to 6×6 in size.

The rule is simple: money symbols that land inside a frame are awarded. A money symbol outside every frame does nothing on that spin, which is why a screen scattered with coins can still pay very little.

Frame size therefore matters as much as coin value. A 2×2 frame covers four positions, a 6×6 frame covers thirty-six, and the larger the frame the more money symbols it can catch in a single spin.

When frames overlap, money symbols caught in the shared area are boosted by up to 10x before being paid. This is the main multiplier source described for Bubble Up!.

The practical effect is that two medium frames crossing over a cluster of coins can outscore one large frame. It also explains why the bonus modifier that guarantees two frames on every spin is valuable: more frames means more chances of an overlap.

Pragmatic Play does not publish the exact odds of each boost value, so treat 10x as the ceiling rather than the expected result of an overlap.

Landing three to six pearl scatters triggers the bonus game with six free spins and between one and four feature modifiers. Frames appear on every free spin, unlike the base game where they turn up at random.

Before the first spin, you select coins to reveal which modifiers are active. The four possible outcomes are:

More coins: extra money symbols on the reels, giving frames more to collect.

More scatters: extra scatter symbols, which feeds the retrigger and expansion rule described below.

Enlarged frames: a bigger starting frame size, so the round begins further up the 2×2 to 6×6 range.

Two frames guaranteed: at least two frames on each spin, raising the chance of overlaps and their boosts.

Since the round starts with only six spins, the modifiers do a lot of the work in shaping how a bonus plays out. A round with enlarged frames and two guaranteed frames behaves very differently from one with a single coin modifier.

Scatters keep mattering once the bonus has started. For every three scatters that land during the feature, two more free spins are awarded and frames expand one level.

Expansion stops at the 6×6 maximum. That makes scatters doubly useful in free spins: they extend a short round and they widen every frame that follows, which in turn catches more money symbols.

This is also where the more scatters modifier earns its place. It does not pay directly, but it feeds both the extra spins and the frame growth, so its value shows up later in the round rather than straight away.

The demo is useful mainly for learning how frames line up with money symbols. In the base game, notice how often coins land outside any frame, because that sets expectations for spins that look busy but pay little.

In the bonus, pay attention to the coin pick. Count how many modifiers you receive and which ones they are, then compare how rounds with enlarged frames or guaranteed double frames perform against rounds without them.

Keep a rough tally of scatters during free spins as well. Each third scatter adds two spins and a frame level, so it is easy to see how quickly a round can move from small frames towards 6×6.

Bubble Up! stands out because the frames give every spin a clear question: will the coins and the bubbles line up? The overlap boost and the expanding frames in free spins give that question real weight, and the coin-pick modifiers make each bonus feel distinct.

The limitations are on the information side. Only the 96.52% RTP is listed on the provider page, so players who want a volatility rating should check the in-game rules first.

Key numbers: RTP 96.52%, money symbols up to 10,000x, frames from 2×2 to 6×6, overlap boosts up to 10x, six starting free spins with one to four modifiers, and two extra spins for every three scatters in the feature.

What is the RTP of Bubble Up!?

Pragmatic Play lists the RTP of Bubble Up! as 96.52%. The provider page does not state a volatility rating, so it is sensible to open the game's information screen at your casino, which shows the return figure for the version you are playing.

How do bubble frames work in Bubble Up!?

Bubble frames from 2×2 to 6×6 in size land on random grid positions in the base game and bonus. Any money symbol that lands inside a frame is awarded, and money symbols in areas where frames overlap are boosted by up to 10x before they are paid out.

How do you trigger free spins in Bubble Up!?

Land three to six pearl scatters to start the bonus game with six free spins and one to four modifiers. You pick coins to reveal the modifiers, which can add money symbols, add scatters, enlarge the starting frames or guarantee two frames on every spin.

What is the biggest money symbol in Bubble Up!?

Money symbols in Bubble Up! can carry values of up to 10,000x, according to Pragmatic Play. They only pay when caught inside a bubble frame, and those sitting inside overlapping frames can be boosted by up to 10x. The provider does not publish a separate overall maximum win figure.

Can you retrigger free spins in Bubble Up!?

Yes. During the bonus, every three scatters that land award two additional free spins and expand the bubble frames by one level. Frames keep growing this way until they reach the maximum size of 6×6, so scatters extend the round and widen the frames at once.
