FAQ
- How is the score counted?
- You earn points for each correct response across both tasks in a single run.
- Which task should I prioritize?
- Both. A miss on either the color signal or the odd/even choice ends the run.
- Can I play with one hand on a phone?
- Yes. Targets are stacked vertically so they stay tappable on a 360px screen.
- Is this a clinical attention test?
- No. It is a dual-task game for practice, not a diagnosis.
