Watch, then repeat
Press start when you're ready.
Watch the four panels light up in a growing sequence, then tap them back in the exact same order. Get it right and the sequence grows by one more step; get it wrong and the round ends.
This is a classic test of working memory — the kind of skill you use constantly without noticing, like holding a short list in mind while you act on it. Most people plateau somewhere between round 8 and 15 before the sequence outpaces their memory. Your best round is saved so you can track your progress over time.
