How this test works

This game tests how steady and even your hand is. Put your finger or the mouse button down and draw one circle around the dot in a single stroke. When you lift, we fit the best circle to your line and measure how far your line strays from it, on average. Your roundness score is 100% minus that average wobble, so a line that wobbles by 2% scores 98%. Motor-control labs have measured hand-drawn curves like this since the 1980s.
