Rule switching
Move deliberately between the number sequence and the letter sequence.
Attention switching
Trail Switch
Trace one path while alternating between two familiar sequences: 1, A, 2, B, 3, C.
About attention switching
Hold two rules inside one continuous trail
Trail Switch places numbers and letters around one field. The task is to connect them in alternating order: 1, A, 2, B, and so on. Both sequences are familiar, but keeping the switching rule active makes the search different from following numbers alone.
The exercise has a fixed end and reports only completion time and errors. It is inspired by a common trail-making format, but this browser game is practice rather than a clinical test or assessment.
Visual search
Keep the next target in mind while searching a scattered field.
Sequence control
Resume each sequence at the correct place after every switch.
Practice well
Name the next target before searching
After each selection, quietly name the next target before moving your eyes around the field. That small pause reduces impulsive clicks and keeps the alternating rule explicit.
Begin with Easy until the switch feels natural. A longer trail adds search time, but it does not turn the result into a measure of intelligence, attention disorder, or neurological health.
Common questions
About this exercise
What is the correct order?
Alternate the two sequences: 1, A, 2, B, 3, C, continuing until every target is connected.
Does an incorrect click end the round?
No. It adds one error and leaves the expected target unchanged.
Is this a diagnostic trail-making test?
No. It is an informal practice exercise and does not reproduce clinical administration or interpretation.
