Start with the child’s skills
Use 3×3 with numbers 1–9 if the sequence is familiar; move to 4×4 only when the child wants more. An adult can explain the rule and help with taps or a printed sheet. There is no need to enforce a fixed gaze or a target time.
Keep the experience comfortable
A short round is enough. Let the child pause, ask for help, or stop. On a phone, small cells may be frustrating, so a larger screen or paper grid can work better. Compare the child’s attempts only when the size and method are similar.
What research does and does not say
Researchers have observed children and adults performing Schulte tasks, including EEG activity. That is not proof that the game improves grades or treats ADHD. If a child has attention or vision concerns, use appropriate professional advice rather than an online score.
