CALIBRO

CALIBRO is a game where being good doesn't matter — being right about yourself does.

Before each micro-task (mental math, memory, visual estimation, internal clock, reflexes) you declare your probability of success. Then you try. The score rewards accurate self-prediction: claiming 90% and failing costs you dearly; claiming 20% and failing pays well. A skilled but arrogant player loses to a mediocre but lucid one.

The game hunts your uncertainty: every success raises the difficulty of that faculty, every failure lowers it, pulling you toward the zone where you succeed half the time — exactly where knowing yourself is hardest. You can't outgrow it. You can only get more honest.

A 5-minute session ends with your calibration certificate: are you overconfident, underconfident, or calibrated? And on which faculties?
