Sorting Balls and the glass-tube stack puzzle
Sorting Balls turns each move into a small planning problem: you lift only the top ball, then drop it into a tube whose top color matches or into an empty one. The clear bottle look makes the board easy to read at a glance, and the Puzzle setup plays in your browser with no download and no signup.
One-ball moves, one open lane
Because you can only move the upper ball, every tube changes the options for the next turn. That means you often need to free a buried color first, park it in spare space, and then rebuild the stack in cleaner order.
Matching colors without boxing yourself in
The goal is to separate mixed columns until each tube holds a single color. The sorting challenge comes from keeping room for future drops, so a rushed move can force you to undo a stack and recover the sequence.
Similar tube puzzles that use the same planning rhythm
If you like container puzzles, Bird Sort Puzzle uses the same one-piece-at-a-time logic, while Aqua Sort asks you to route pieces into matching stacks. Colors pins leans on color grouping too, and each one rewards careful board reading over speed.
The visual style also fits the colors angle nicely, since every ball in a tube changes the layout you are solving around. If you enjoy balls puzzles that ask you to keep a spare slot open, this one gives you that same planning pressure with a cleaner glass-tube board.
On mobile, you tap a tube; on desktop, you click, so the controls stay simple. That makes mobile play easy to pick up whether you are lining up one more color or fixing a messy stack.
