Bubble Sorting

Pour the bubbly chaos into the proper tubes, match every color, and clear the board before the screen fills up and you're stuck.

You know that moment when you've got four red bubbles stacked under three blues and suddenly realize you've painted yourself into a corner? That's Bubble Sorting. Each level hands you a set of test tubes crammed with mixed-up colored bubbles. You can only move the top bubble from one tube to another—and it only lands if the tube is empty or the top bubble already matches. Simple on paper, but three moves later you're staring at a tiny tower of red with a blue trapped underneath, wondering how to undo your last ten decisions. The first few levels feel like a warm-up: two colors, plenty of empty tubes. Then it sneaks in a third color, a fourth, and you're staring at a full rack of tubes with no obvious move. That empty tube you've been treating as a free space? It becomes your most valuable asset. I found myself restarting whole sections because I'd sacrificed my only empty tube on an impulsive move. The satisfaction of finally clearing a color—watching those matching bubbles stack into a perfect column—kept me coming back even after I swore I'd stop at one more level. It won't melt your phone, but it'll quietly eat your lunch break. There's no timer, no pressure, just a clean puzzle that respects your patience and punishes sloppy planning. If you like logic games that feel like tidying up a messy desk, this one scratches that itch hard.

Always keep at least one empty tube open as a buffer—losing it can lock the whole board. Look ahead before moving a bubble; sometimes leaving it where it is lets you stack a whole color later. If you're stuck, undo a few moves instead of restarting from scratch—often just one bad move caused the block. Start by clearing one color completely; it frees up space and simplifies the remaining tubes. Don't rush to fill a tube with a color that's still scattered all over the board—that's a trap. Use the top bubble as a hint: if you see three of the same color in different tubes, that's your next target.
