Tangled Lines· Advanced

Goal

Lines start from letters (A, B, C...) at the top and end at numbers (1, 2, 3...) at the bottom. Trace each curve to identify its endpoint.

How to Play

  • Tap a letter to highlight its line in bold
  • Follow the curve visually, then tap the correct number
  • A wrong tap flashes red and reduces your score

Tip

  • Trace one line at a time — following several at once causes errors
  • Use line color and dash pattern as additional cues

Tangled Lines is a visual tracking task grounded in Multiple Object Tracking research, measuring your ability to monitor several paths in parallel.
