TRAIL BlinkTest

BlinkTest is a fast memory puzzle for short play sessions. Study a grid of cells, remember how they look, then tap the single cell that changes after a quick transition.

How it works
You get a few seconds to memorize the layout. The view updates in one move, one color shift, or one swap. Your job is to tap the cell that is different. Correct answers build your score and streak. Wrong answers cost a life. When lives hit zero, the run ends and you can try again to beat your best.

Who it is for
Anyone who likes brain teasers and reaction games without accounts or tutorials that never end. Sessions are short, so it fits a commute, a break, or a quick challenge with friends.

Privacy in short
No sign-in is required. We do not use in-app analytics or ad tracking SDKs in this build. Your scores and settings stay on your device unless you clear app data or uninstall.

Notes for parents
