Tap Square

What it is

A test of colour perception. The screen fills with squares of the same shade except one: tap it and the next board appears, a little harder.

The grid grows from 2×2 to 5×5 and the two shades keep creeping closer until they sit a single step apart. There are two modes, with and without a clock, each with its own best score.

Nothing in the way

No ads, no in-app purchases and no connection. The game works the same in airplane mode, and it bundles no third-party SDK.

Privacy, in one line

The only thing stored is your two best scores, on your device. Nothing is collected, no permission is requested and there is no network request at all.
