Coin Flip

Flip a virtual coin and let heads or tails decide — quick, no sign-up, with a short history of your recent flips right in view.

Local processing: your data is processed in your browser and never sent to Numelto or any external service.

A local random decision — not a certified flip, just a quick way to decide between two options.

How to flip the coin

Click "Flip coin" and wait for the animation to finish — the result (heads or tails) appears right inside the coin. Flip as many times as you like; a short history of recent flips is kept, only on your screen.

Use cases

A few common examples:

  • Decide who goes first in a game.
  • Choose between two equally valid options without overthinking it.
  • Replace a physical coin when you don't have one handy.
  • Teach basic probability (each side has a 50% chance).

Is this a certified flip?

No. It's a local random decision generated in your browser, meant for everyday and casual decisions — it's not presented as a legally valid or certified flip; specialized, externally audited services exist for that.

Privacy

The result never leaves your browser: it's not sent to Numelto, not logged, and not stored anywhere beyond this tab.
