How to use it

  1. 1

    Choose Part A or B

    Part A is numbers only. Part B alternates numbers and letters, which adds the harder job of switching between two sequences.

  2. 2

    Connect in order

    Tap 1, then 2, then 3, and so on. The timer starts on your first tap and a trail follows your path.

  3. 3

    Beat your time

    A wrong tap is counted but does not stop you. Your time and any wrong taps show at the end.

When it comes in handy

Frequently asked questions

What is the difference between Part A and Part B?
Part A asks you to connect numbers in order, which mainly tests visual search and processing speed. Part B alternates numbers and letters, so on top of searching you have to switch between two sequences in your head, which is why it usually takes longer.
What is a good time?
Times vary a lot with screen size and how the dots are spread, so treat the number as a comparison with yourself. Most people finish Part B a fair bit slower than Part A, and a smaller gap between the two suggests smoother task-switching.
Is this a medical or diagnostic test?
No. The trail making test exists as a real neuropsychological screening tool, but this is a fun, informational version for practice and timing yourself. It is not a clinical assessment and should not be used to diagnose anything.
