Bubble Sort Puzzle

Colored balls rest inside stacked shapes above a gray platform. Bubble Sort Puzzle uses that unstable layout for an attention puzzle with many rounds and rising difficulty. Matching each ball to the figure of the same color clears that figure from the pile, opening more room in the stack. One bad placement can drop pieces below the gray base and end the attempt.

How to play?

At the board, move balls into figures that share their color until the inside matches the frame. A completed figure vanishes and leaves an empty spot for the next move. Plan placements ahead, because falling pieces below the gray platform mean a loss. Careful sorting and steady attention are required to finish the full puzzle.
