The basic rule
Start a round, find 1, then 2, and continue until the final number. A new round shuffles the positions. Letter, color, reverse-order, and red-black pages use different target rules.
What Is a Schulte Table?
A Schulte Table is a square grid of shuffled targets. On this site, you select numbers in ascending order while the browser records time and errors.
Page guide
Grid size and cell count
The supported number grids run from 3×3 (9 cells) to 10×10 (100 cells). The 5×5 version contains 25 cells, but it is simply one available size rather than a clinical or population standard.
What the browser records
The tool can store recent time and error history locally on your device. It has no account, cross-device profile, public ranking, or verified population dataset.
Source boundary
This page limits itself to observable rules and site behavior because the reviewed source set does not establish a reliable history of the task.
Frequently asked questions
How many cells are in a 5×5 table?
There are 25 cells, calculated as 5 × 5.
Must I keep my eyes fixed at the exact center?
No. A central gaze can be a practice cue, but move your eyes as needed for clear and comfortable viewing.
Is a Schulte Table a medical or vision test?
No. This site provides a general visual-search activity and does not diagnose or assess a health condition.
