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 this Random Multiple Generator

Set a minimum, maximum, divisor, and quantity to draw matching multiples with optional uniqueness.

What this tool does

Generate random integers that are exact multiples of a chosen positive integer.

Practical tips and limits

Generation happens locally with browser cryptographic randomness. The tool is designed for testing, examples, classrooms, and simulations rather than regulated or externally auditable draws.
