Start with the task you actually want to complete. A standard number grid is the clearest introduction to the order rule. Use a reverse or letter mode when you want a different target sequence, a generator when you need a particular layout, and the tracker when the goal is reviewing comparable attempts rather than playing another round.
Practice tools create a grid and record what happens during a round. Score tools work with results you already have. The calculator applies a visible, site-defined formula to time and mistakes; the tracker summarizes your own saved attempts. Neither tool produces a clinical result, universal comparison standard, or public rank.
Timing is optional in several practice modes. Use a visible timer when pacing is part of your session, hide it in coach mode when it distracts from the sequence, or print a grid for an offline activity. A total time is most useful when the size, mode, device, input method, and completion rule remain similar.
The reverse table and concentration grid can save completed rounds to the unified progress tracker. The score calculator saves only after you press its save button. Generator and printable pages do not need to store personal results. Tool cards and the comparison table identify these differences before you open a page.
Use the printable page for prepared sheets or the generator when you need a fresh arrangement. Printing happens through the browser, so there is no server-side PDF job. In a group setting, explain the target order before starting and avoid treating completion time as a grade or a comparison between learners.
Selections made in this directory are temporary. Saved attempts use local browser storage and can be exported or deleted from the tracker. No name, email address, IP address, or device fingerprint is added to an attempt. Exported JSON and CSV files are created locally and are yours to manage.
A 3×3 or 4×4 standard number grid gives the shortest introduction to the basic sequence rule.
No. A small rule set matches your selected goal, category, and difficulty to one to three tools in the browser.
The directory still exposes categorized links, but playable grids, calculations, filtering, and saved history require JavaScript.
No. Each card states whether the tool keeps history, and the calculator saves only after an explicit click.
