Visual search under noise: start with a 1-minute practice, then push your speed and control in Normal 1–3 modes.

The Poppelreuter task is a classic example of figure-ground perception and selective attention. You must extract the relevant signal (the next smallest center number) while ignoring distracting information (the bottom-right numbers).
Points are based on correct answers, with a small speed factor so that faster accurate runs score higher. In history you see points plus accuracy for each run.
Disclaimer: training/insight only; not a diagnostic test.
The center number is the rule for the search order. The bottom-right number is the response you must produce. This forces you to keep the rule in mind while filtering out interference.
No. Practice is a warm-up and is not saved. Only Normal 1–3 runs are saved to your history and used for points.
Pick one scan pattern and stick to it for the entire run. Focus on accuracy first. When you can keep accuracy high, speed will follow naturally.
Small screens and touch keyboards slow down scanning and typing. The test works, but results are usually more stable on a desktop keyboard.
