Description
Connect numbered circles in order as fast as you can. Part A uses numbers only; Part B alternates between numbers and letters. A classic clinical measure of visual attention, processing speed, and cognitive flexibility.
How It Works: Click the circles in the correct sequence — Part A is 1 → 2 → 3 → ... → 25. Part B is 1 → A → 2 → B → 3 → C → ... → 13. The timer starts on your first click. Wrong circles count as errors but don't end the run.
Why It Matters: Trail Making is used clinically to assess attention, visual scanning, and the ability to switch between rules (Part B). It's one of the most sensitive tests for detecting subtle attentional issues, and the difference between Part A and Part B — the "switching cost" — reflects how efficiently your brain shifts between two competing tasks.
Tips: Scan ahead before clicking. Keep a smooth rhythm instead of rushing single jumps. A small, consistent pace beats sporadic bursts — accuracy compounds.
