Oddgrid

One of these tiles isn't like the others. Can you see it?

Oddgrid is a pure test of your eyes. A grid of identical tiles fills the screen — except one, which is a fraction of a shade different. Tap it and the round advances: the grid gets bigger, and the difference gets smaller. Keep going as long as your eyes hold out.

It starts almost insultingly easy and turns brutal fast. By the later rounds you'll be squinting at a wall of tiles hunting a shade that barely exists, with the clock ticking and a wrong tap costing you. There's a timed mode where every second counts, an endless mode that runs until you slip, and a relaxed mode with no pressure at all. Your best round and high score are saved, so there's always a wall to break through next time.

Oddgrid works in both English and Slovenian — choose your language on first launch and change it anytime in settings. No account, no internet, no ads; it all runs on your device.

Find the odd one, and keep finding it.
