What is Bubble Up!?

Bubble Up! revolves around winning combinations of three to six sea-creature symbols and Money symbols that can carry values of up to 10,000x the stake. Its standout mechanic is the Bubble Frame system.

These frames can appear across random positions on the grid and range in size from 2x2 up to a maximum of 6x6. When a Money symbol lands inside an active frame, its value is awarded. If frames overlap, a Money symbol positioned within that overlapping area can also be boosted by up to 10x before being paid.

This means the position and size of the frames are just as important as the Money symbols themselves. The larger the active area becomes, the more positions can fall within reach of the collect mechanic.

Bubble Frames

Bubble Frames can appear on random positions during both the base game and the bonus.

Money symbols landing inside an active frame are awarded. The mechanic becomes more powerful when multiple frames overlap. A Money symbol within an overlapping area can receive a boost of up to 10x before its value is paid.

During the base game, the frames can already appear in different sizes. In the Free Spins, their growth becomes part of the bonus progression, allowing increasingly larger sections of the 6x6 grid to fall within an active frame.

Free Spins

Landing 3 to 6 Pearl Scatter symbols triggers the bonus with 6 initial Free Spins.

Before the feature begins, coins are selected to reveal between one and four modifiers. These can improve the starting setup of the bonus in different ways.

Possible effects include additional Money symbols, extra Scatter symbols, larger Bubble Frames from the start or two guaranteed Bubble Frames on every Free Spin.

At least one Bubble Frame appears during every Free Spin, keeping the game's main mechanic active throughout the entire bonus.

Feature modifiers

Before the Free Spins begin, between one and four modifiers are revealed. These determine how strongly the bonus starts and which parts of the core mechanic receive an immediate boost.

The possible effects can:

• add extra Money symbols
• add extra Scatter symbols
• increase the starting size of the Bubble Frames
• guarantee two Bubble Frames on every Free Spin

The modifiers therefore influence both the number of Money symbols available and how quickly the Bubble Frame mechanic can develop.

Retriggers and growing Bubble Frames

Scatter symbols remain important throughout the Free Spins.

For every three Scatters that land during the feature, 2 additional Free Spins are awarded. At the same time, the Bubble Frames expand by one level.

This allows the frames to grow progressively from 2x2 up to a maximum of 6x6. As they become larger, they cover more positions on the grid and create more opportunities for Money symbols to land inside one or more active frames.

Overlapping frames and multipliers

The Bubble Frame mechanic becomes especially important when two or more frames overlap.

Money symbols positioned within an overlapping area can receive an additional boost of up to 10x before their value is paid.

This creates a direct interaction between frame size, frame position and Money symbol placement. Larger frames can cover more of the grid, while overlapping areas can significantly increase the value of Money symbols that land inside them.

Why Bubble Up! stands out

Bubble Up! stands out because its bonus progression is built around one mechanic that keeps becoming more powerful.

Extra Scatters do more than extend the feature. They also increase the size of the Bubble Frames, while the starting modifiers can add more Money symbols, more Scatters or larger frames from the outset.

These systems work together naturally: more Scatters extend the bonus, larger frames cover more positions and overlapping frames can boost Money symbols by up to 10x. This gives the Free Spins a clear sense of progression rather than keeping the same setup from start to finish.

Is Bubble Up! worth playing?

Bubble Up! is well suited to players who enjoy very high-volatility video slots with a central mechanic that can build throughout the bonus. The Bubble Frames are easy to understand, but the interaction between retriggers, modifiers and overlapping areas adds extra depth.

With growing Bubble Frames, Money symbols worth up to 10,000x and a maximum win of 10,000x the stake, Bubble Up! offers a distinctive feature-driven experience from Pragmatic Play.
