Twindow: Find the Difference

Two windows onto the same warm little world. Five things are different.

Twindow is a find-the-difference game built for people who want to look, not to hurry. A bakery counter at closing time. A greenhouse in soft afternoon light. A harbour street with the boats in. Two scenes, five differences, as long as you like.

No clock running. There is no countdown and nothing to lose. A wrong tap only locks the pictures for a moment, so guessing never pays. Play one scene or twenty.

Every difference is measured before it ships. Each difference is scored for how visible it actually is — colour distance, edge contrast, size, and how busy the surroundings are. Nothing is hidden in a single pixel, and nothing depends on telling two nearly identical colours apart.

A new scene every day. Everyone gets the same Daily Scene. Keep a streak, and share your result as a small grid that gives nothing away.

Works fully offline. On a plane, on the underground, in the garden. Your stars, album and streak are kept on this phone.

Stuck? After a run of misses, or a quiet spell with nothing found, the strip between the two windows offers a short video: watch it and Twindow frames the area where a difference hides (or reveals one), or tap Keep looking and carry on. Other ads appear only between scenes and on the menus, never over the pictures while you play.

Every scene is free. If you would rather play without banners and between-scene ads, there is an optional one-time purchase, Remove ads: tap the red "No ads" label in the corner of the Home postcard or on the top strip of a scene, or open Settings, where Restore purchases sits right below it. Hint videos stay optional either way.
