What the result means
We report your literal exact rate, mean absolute error and response time on this task. We do not turn them into an IQ score, diagnosis or invented population percentile.
Display size, viewing distance, interruptions and input method can change performance. Compare your own runs under similar conditions.
Modes & controls
Quick Flash
Twelve brief quantity flashes. Standard separates 1–4 small sets from larger estimates; Hard adds look-alike decoys.
Selective
Five visible symbol fields. Count only the named target while ignoring similar marks.
Precision
Ten visible fields with no speed bonus. Exact counting is the only goal.
Sprint
Answer as many visible fields as you can before the active timer expires. Paused time does not count.
Keyboard
Type digits, Enter to submit, Backspace to edit, P to pause, F for Focus and M for sound.
Deterministic replay
The Practice seed in the URL recreates the same layouts. Daily uses the date as its identity.
Strategy & exact review · optional
