About this game

Random Key is an arc-bend judgment game. Several arc lines appear at once, and you tap the most or least bent arc as prompted to score. Wrong picks count as mistakes, with three mistakes ending the run. Bend differences shrink later, making extreme arcs harder to spot at a glance. Rushing before you compare curves burns the error budget under rising subtlety. There is no highlight assist after a wrong pick. Clear arc outlines keep bend extremes readable when you scan carefully. Simple prompt-and-tap rules with a three-wrong fail. Ideal for visual comparison fans who like shrinking differences and quick retries.
