Schulte table

Find 1…N² in order on a shuffled grid — a visual-scan drill with a timer.

Runs entirely in this browser. Times are not saved or sent anywhere.

A 3–7×N grid of numbers 1…N² — find them in order. Measures your sustained visual scan, not an IQ.

How to use

  1. Pick a grid size and start.
  2. Tap numbers in order.
  3. Read total and per-cell times.

What it supports

Grids 3×3 to 7×7; timer runs to finish, mistaps are counted. Measures sustained visual scan on your device — a practice metric, not a clinical score.
