Eyeball It!

Six ways to find out how good your eyes really are. Eyeball It! is a minimalist estimation game. No rulers, no measuring, no counting — every round asks you to judge something by eye, then shows you exactly how close you got. LENGTH A shape appears. Drag out one straight line as long as its whole outline, then watch your line fold back onto the shape to reveal the error. VOLUME Hold to pour into an oddly shaped vessel until you reach the target. The cross-section changes as it fills, so the surface rises unevenly — judge the volume, not the level. COLOR Mix cyan, magenta and yellow ink to match a target swatch. On reveal the bars glide to the exact recipe, so you can see where your mix went wrong. TIME Watch a traffic light mark out two intervals, then reproduce both from memory. BALANCE Tap the single point an irregular shape would balance on. It tips toward your guess, then settles onto the true one. COUNT A field of dots flashes for under a second — far too many to count. Trust the impression and name a number. Every round is scored on how close you came, and every mode keeps its own level that tightens as you improve. • Six distinct estimation challenges • Light and dark themes • English, 中文 and 廣東話 • Soft sound effects and calming background music, with separate volume sliders • No account, no sign-up • Works offline — your progress stays on your device Trust your eyes.
