Angle Lab

Match the direction of each line. Pick a difficulty on the side: harder modes take away the grid, score where your lines sit, and finally hide the target while you draw.

How to play
  1. Study the target. The highlighted segment is the one to draw next.
  2. Press to drop a start point, then drag and release where the line should end (or tap twice). Right-click cancels the line you’re drawing.
  3. Match the direction, not the length. Average under 6° to pass. Every level is open — jump to any of them.

Each bar is one round’s angle accuracy — taller is better. It’s 100% for a perfect angle and about 55% at 6° off, the pass line. Blue diamonds are position accuracy for rounds played with position scoring (about 51% at 30 px off, the pass line), joined by their own 5-round average. Hover or tap a round for details. In Hard and Extreme, overall accuracy is the average of the two scores. Each difficulty keeps its own history, stats and streak. Progress is saved in this browser.
