How much do you trust your eyes? Match the color, count the time, test your reflexes — closest wins. Open a room, share the 4-letter code, friends join on their phones. How good are your senses, really? KALIBRE is a perception test game: we show you something, it disappears, and you rebuild it from memory. Closest guess wins. 15 SENSE TESTS — IN ONE GAME • Color, Gray — nail the shade you just saw • Sound (Pitch) — find the frequency by ear • Time, Tempo — test your inner clock • Angle, Length, Area, Shape — measure with your eyes • Count — no time to count, feel the number • Reflex — catch the moment, milliseconds count • Bisect — split an object into two equal halves • Tracking — follow the dots with your eyes • Odd One Out — spot the different tile in the grid • Memory Sequence — watch a growing sequence and repeat it ARENA — RACE THE WORLD Seasons reset every week. Earn points and climb the global leaderboard. Everyone starts from zero on Monday. PARTY MODE Open a room, share the 4-letter code. Everyone in the room locks in on their own phone. After each round the live board shows who drifted how far. No sign-up, no accounts — the code is enough. DAILY The same rounds for everyone, every day. Share your score as an emoji card and keep your streak. YOUR SENSORY FINGERPRINT See which senses you master and which you don't, on one radar chart. DIFFICULTY Easy / Hard / Brutal. Brutal hides the numbers, shortens the look, tightens the tolerance. Turn on RAMP and the match hardens round by round. Turn on SNAP and lightning 4-choice rounds sneak in. SCIENTIFIC SCORING The color score isn't a guess — it's computed with CIELAB ΔE2000. Your closeness is real, your score is earned. Free. No ads ever in the middle of a live party round.
