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 timer. No lives. Nothing to buy.
You never run out of anything. There is no energy bar to wait on, no coins to
collect, and no shop — because there is nothing in this game to sell you. 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.
Colour-only differences must also change in brightness, so they stay findable
if you are colour blind.

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.
No account, no sign-in.

Ads appear between scenes and when you ask for a hint — never in the middle of
a scene, never over the pictures.
