About BubbleStack

BubbleStack is a physics-driven arcade game about constructing the highest bubble tower you can manage. You aim colorful orbs into position, then decide whether a placement should help the stack grow or remove matching bubbles from the structure.

Every shot affects the balance of the tower, making precision as important as matching. Three bubbles of the same color can disappear together, opening room for the next placement, while a poorly judged move may cause gravity to pull the whole construction down. The endless format supports repeated high-score attempts.

How to Play BubbleStack

Click with the mouse or tap the screen to launch and place a bubble.

Aim each colorful orb so it joins the tower in a stable position.

Create groups of three matching bubbles to remove them from the stack and make room.

Keep building upward while protecting the structure from a collapse caused by an unstable placement.

Tips & Tricks

1Line up matching colors when a trio can improve the tower rather than placing an orb without a purpose.
2Favor supported placements near the existing structure, since loose additions can upset its balance.
3Before launching, consider where gravity will pull the bubbles after they connect.
