What it trains

Why take the Trail Making Test

The exercise works your cognitive flexibility and visual search: after a number you look for a letter, after a letter for a number, all while remembering where you are in both series.

After each round you see how many circles you connected, how many boards you finished and how many mistakes you made. Sign up and your rounds are saved, with a 30-day chart in your account.

Method

What the exercise is based on

The exercise recreates the second part of the well-known Trail Making Test. It appeared in the 1940s: in Part A you connect only numbers, in Part B you alternate numbers and letters. It’s Part B that loads switching.

If you want something easier, start with the Schulte Table, where you only find numbers in ascending order. A similar alternation of two series is used in the Gorbov–Schulte Table.
