Impossible

Open Impossible and you are playing — a Hypercasual game that runs on the page rather than beside it. It is built for touch, so a phone or a tablet is the natural place for it. Tagged casual, hypercasual, strategy.

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.
