Flip a Coin

This coin flip tool gives you a genuinely fair heads-or-tails toss without digging through your pockets for change. Each flip draws from your browser's cryptographically secure random number generator, so the outcome is a true 50/50 — decided the instant you click, then revealed with a satisfying tumble. Flip once for a quick call, or play a best-of series when a single toss feels too final.

How to use:

1. Choose a mode: single flip, best of 3, or best of 5
2. Click "Flip the coin" and watch it spin
3. The coin lands on heads or tails and the result is announced
4. In best-of modes, keep flipping until one side wins the round
5. Check the session history row to see every flip and the running tally

Common Use Cases:

• —Settling a friendly disagreement with a neutral coin toss
• —Deciding who goes first in a game, debate, or sports match
• —Making quick two-way choices — this restaurant or that one
• —Teaching probability with a fair, repeatable 50/50 experiment
• —Running a best-of-3 or best-of-5 when the stakes deserve more than one toss
• —Replacing a physical coin when you don't have one handy
