One tile is a slightly different shade. Find it. That's the whole game — and it goes deeper than you'd think. The gap shrinks level after level until it's roughly 1 ΔE, the smallest colour difference a human eye can detect at all. Most people tap out somewhere in the low twenties. That's not a failure. That's your retina. A 200-LEVEL JOURNEY Start easy and climb through eight chapters. Each level is a handful of boards, each subtler than the last, and you earn up to three stars for a clean run. Miss a tile and the game shows you the one you should have found — so every mistake teaches. Two hundred levels, from a gentle warm-up to the very edge of human vision. AND SIX MORE WAYS TO PLAY • Classic — points for speed. Tap the odd tile in under a second and it's 1000. • Daily — one board a day, identical for everyone on Earth. Compare and argue. • Sprint — 60 seconds. Clear as many as you can. A miss costs you four. • Endless — no safety net. The clock tightens with every level you clear. • Sudden Death — three lives, no clock. Just your eye, taking its time. • Zen — no clock, no lives. Pure practice. (Pro) MADE WITH ACTUAL CARE • Difficulty is measured in CIELAB ΔE — a perceptual unit — so level 12 is exactly as hard on a deep blue as it is on a pale yellow. Colour games that step raw RGB or HSL values quietly make some hues far harder than others. This one doesn't. • The odd tile always differs in lightness, never hue alone, so it stays playable if you're colour blind. • Every colour is checked to be inside the sRGB gamut before it's shown, so the gap you're hunting is exactly the gap intended — never a clipped approximation. • Global leaderboards through Game Center. QUIETLY RESPECTFUL • No ads. No accounts. No tracking. No analytics. • Plays fully offline — leaderboard scores sync whenever you're next online. Your eye is better than you think. Right up until it isn't.
