One tile is a different shade. Find it before the clock runs out.
One tile is slightly different. Tap it. Each level the grid grows and the difference shrinks. You have 30 seconds. Wrong taps cost 2 seconds.
This is a color discrimination challenge: every round shows a grid of identical tiles, except one that's a slightly different shade of the same color. Tap the odd one out. Each level the grid gets bigger and the difference gets subtler, until you're squinting at tiles that look absolutely, definitely identical. They aren't. You have 30 seconds and wrong guesses cost you time.
Human color discrimination varies a lot more than people assume. The average player clears around 12 to 15 levels. Above 20 suggests genuinely sharp color perception of the kind designers and photographers rely on, and above 25 is rare. Your result comes with a percentile so you know exactly where your eyes rank.
A note for the competitive: screen quality and brightness genuinely affect this test, so compare scores on the same device. Also, this is a fun perception game, not a medical exam. If colors consistently look off to you in daily life, an optometrist can run a proper color vision assessment.
