Blocks8

No download, no account: Blocks8 is a Puzzle game that runs where you found it. It is built for touch, so a phone or a tablet is the natural place for it. Catalogued as arcade, block, bricks, casual, puzzle.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Nothing is saved to an account, because there is no account — progress lives in this browser.
