Schulte Table Practice

Choose by sequence length

A 3×3 or 4×4 grid creates a short sequence for learning the controls. The 5×5 grid is the site's fixed 25-target condition. Sizes from 6×6 upward deliberately add more selections and denser targets.

• Short sequence: 3×3 or 4×4.
• Standard 5×5: 25 ordered targets.
• Longer sequence: 6×6 through 10×10.

Choose by rule

Keep an ascending number table when you want one numeric rule. Choose reverse order, a letter sequence, number–letter alternation, or the red-black color rule only when that specific variation is the task you want.

What counts as a fair repeat

Compare the same size, order rule, device, input method, zoom, and error behavior. Selecting a different task is a variation, not a higher or lower ability label.

Is this page free to use?

Yes. It runs in the browser without an account.

How do I choose a grid?

Choose a readable size that you can complete accurately. A smaller grid creates a shorter task.

Can I compare every mode together?

No. Compare attempts only when the grid, target order, and input method are the same.
