Flip a fair virtual coin that lands on heads or tails with equal probability using Math.random() in your browser. No data leaves your device.
When to use it
- Break ties in casual games
- Demonstrate binary random outcomes in classrooms
- Quick decision prompts when both options are acceptable
Limitations
Not cryptographically secure—do not use for gambling or security. Each flip is independent; past results do not affect the next flip.
Fairness note
Outcomes are pseudo-random; for audited draws use a certified random source instead of a browser toy.
