Watch a pattern light up, then play it back. It grows by one each round — a simple, oddly satisfying way to stretch the working-memory muscle that ADHD brains lean on hardest.
Reverse mode = play the pattern backwards. Much harder — a real memory workout.
Miss one and it's over — see how far you get.
Why it's built this way. Working memory — holding a few things in mind and using them — is one of the most-documented ADHD load points, and it's trainable. Reproducing a growing sequence forces you to hold, rehearse and act, exactly the loop that helps working memory get stronger. It's short, escalating, and matched to your level, which keeps a restless brain locked in.
