Trail making
Join the numbers in order. Then alternate numbers and letters.

An example to explore. No score or practice round is recorded.
Part B runs 1 to 8 and A to G. More circles means a longer search for each one.

Join the circles in order
Read the board for as long as you like. The clock starts when you tap the first circle.
Tab moves through the circles from the top row down, left to right. Enter or Space taps the one in focus. Typing a number or a letter taps that circle. Escape or End ends the round.

Round details
The gap between part B and part A is what clinicians look at. This page is practice, not a clinical test.

How this data is usedHelp
A wrong tap counts as one mistake. The circle turns red and the trail stays where it was. Joined circles stay marked and a line links them in order.
Part B makes you switch between two sequences while you search. Both parts have the same number of circles.
Finish both parts to save one round in this browser. A round you end early is not saved.
The statistics page compares rounds with the same number of circles. It shows your accuracy and how long both parts took.
This is the format used in neuropsychology. German police and aptitude testing use it too, where it is called a Konzentrationstest. That is German for a concentration test. Your screen, your pointer and how you sit change the time, so a browser time is not comparable with a paper one.
