Bubble Sorting Unblocked — Play Free Online

Ball sort, run as a campaign

Bubble Sorting is the tube puzzle presented as a level list rather than an endless run. It opens on a grid of numbered levels under an EASY heading, most of them locked, and you work along the row unlocking as you clear.

The puzzle itself is the one you already know: tubes of mixed coloured balls, and you pour from one to another until each tube holds a single colour. Only onto an empty tube or onto the same colour.

What the level structure changes

• Difficulty is curated rather than random, so a level that will not solve is a level you have misread, not a bad deal.
• Because levels are fixed, a reset is genuinely free — the layout comes back identical and you can try a different first move.
• The early levels teach specific patterns. Skipping ahead is possible and makes the middle of the list much harder than it needs to be.

The habit that clears levels

Work out which colour you can complete first and make every early pour serve it. Finishing one colour empties a tube, and an empty tube is the only thing that lets you rearrange anything else.

The losing position is always the same: every tube topped with a different colour and none empty. Once you can see that coming two moves out, most of the list falls.
