Visible randomness and repeat-use workflow

v10.76 preserves the established Random Tools engines while connecting secure browser-local drawing, no-repeat rounds, team workflows, history, projector-friendly output, and copy/export reuse. Where current browsers support it, new shared selection helpers use crypto.getRandomValues() with rejection sampling rather than Math.random().

Fairness and randomness boundaries

Random selection can make equal-probability choices from the entered pool, but it cannot prove that the input list itself is appropriate or unbiased. Visual wheel/dice animations are presentation only. Seeded tools remain reproducible pseudo-random workflows rather than cryptographic randomness, and rating-balanced teams use a transparent heuristic rather than an optimal or human-judgment model.

How to use the Random Number Table Generator

Choose the inclusive integer range, rows, and columns. Turn on no repeats when every cell must be unique, then copy the grid as tab-separated text or download CSV.

What the result means

Each cell is sampled locally with browser cryptographic randomness. Unique mode applies across the entire table, not only within a row.

Practical tips and limits

Use this for worksheets, simulations, and test data. It is not an externally auditable draw service, and unique tables cannot contain more cells than integers in the selected range.
