Tips och bästa praxis
- Math.random gives a fair 50/50 distribution — the right tool for everyday "heads or tails" decisions.
- NOT cryptographically secure; do not use for secret bit-generation. The random-string-generator or dice-roller use crypto.getRandomValues if you need that.
- For "best of N", flip multiple times and take the majority — uses the law of large numbers, removes single-toss bias.
- For weighted decisions (e.g. 70/30), use the random-number-generator with a custom range and threshold.
- Flip history shows the last 20 results; refresh to reset.
Vanliga frågor
Is the coin flip truly random?
Yes, the tool uses JavaScript's Math.random() which provides a cryptographically sufficient pseudo-random number for coin flips, giving a fair 50/50 chance.
Can I flip multiple coins at once?
Yes, you can flip 1, 2, 5, 10, or 100 coins at once. The results and statistics are tracked for all flips.
Is my data private?
All processing happens in your browser. No data is ever sent to any server or third party.
Does it work offline?
Once loaded, the tool works entirely offline. All processing is done client-side with JavaScript.
Can I see my flip history?
Yes, the tool displays your last 20 flips as colored circles. Gold circles represent heads, and silver circles represent tails.
