Using a virtual coin flip — Guide

Guidance for Virtual Coin Flip. Practical instructions, limitations, and accuracy tips.

This article explains the use and limitations of the interactive tool. No signup is required. Output can be approximate and should not substitute for authoritative sources when the stakes are high.

Two outcomes

The virtual coin chooses between two equally weighted outcomes using your browser’s secure random number generation API.

Independent flips

A previous head does not cause tails to become more likely on the next flip. Each new result is independent.

Appropriate uses

Use flips for ordinary choices and games, not as proof of physical randomness or to make safety-critical decisions.
