About this coin flip tool
This free online coin flip uses crypto.getRandomValues() — the same cryptographically secure randomness your browser uses for security — to ensure every flip is genuinely 50/50. No patterns, no bias, no tricks.
Perfect for settling disputes, making quick decisions, classroom activities, game night, sports team selection, and anywhere you need a fair random result.
Is this coin flip truly random?
Yes. We use crypto.getRandomValues(), a cryptographically secure random number generator built into your browser. It's the same method used for SSL certificates and encryption. Every flip is independent — past results never influence future ones.
Can I flip multiple times quickly?
Yes — just click the button or tap the coin repeatedly. Each flip is instant and independent. Your full history and running totals are tracked on this page.
Is this free to use?
Completely free, no account needed, no limits on how many times you flip.
Does it work on mobile?
Yes — just tap the coin or the Flip Coin button. Works on all modern phones and tablets.
