Angle Lab

Match the direction of each line. Turn on position scoring in Settings if you also want to match where the lines sit.

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).
  3. Match the direction, not the length. Average under 6° to level up.

Accuracy per roundPassedMissed5-round average

Each bar is one round — taller means more accurate. Hover or tap a bar for details. Accuracy is 100% for a perfect angle and drops to about 55% at 6° off, the pass line. With position scoring on, accuracy is the average of the angle and position scores and you also need under 30 px average offset to pass. Progress is saved in this browser.
