About this game
Ball Packing Master Puzzle – Fill Box is a sorting puzzle where every colored ball has exactly one place to go. You drag balls across the screen and drop them into the boxes that match, filling each one until the board is clear. The rules take a few seconds to learn, but the layouts get trickier the further you go.
Careful planning matters here. A single careless move can block the balls you need next, so it pays to look at the whole board before you commit. When a level feels stuck, the built-in boosters can help you untangle it without starting over.
The pace is calm and the colors are bright, which makes it a good fit for short breaks or longer relaxed sessions. Levels start gently and slowly demand more thought. Can you sort every ball and finish them all?
How to play
On desktop, click a ball, hold, and drag it into the box you want. On mobile, tap a ball and slide your finger to move it. Match colors in each box and use boosters when you get stuck.
