Virtual coin flip
Flip a Coin Online – Free Heads or Tails
Tap for an instant heads or tails call. Fair 50/50 randomness in your browser — no app, no ads, no account.
How to flip a coin online
FateDecider’s online coin flip uses the Web Crypto API (crypto.getRandomValues) so each result is an unbiased heads or tails — not Math.random(), and not a server-side roll you have to trust blindly.
Use a single flip to settle a tiny tie, switch to best-of-3 or best-of-5 when you want a short series, or flip several coins at once when one toss is not enough. Session flip counts stay in local storage on your device only.
Looking for something more than yes/no? Try the decision wheel for many options, or the yes or no generator when you want a written answer instead of a coin face.
Online coin flip FAQ
Is an online coin flip actually random?
Yes. Each flip uses your browser's cryptographically secure random number generator (Web Crypto's getRandomValues), not Math.random(), so heads and tails are exactly 50/50.
Can I flip more than one coin at once?
Yes — use the modes below the main coin to flip two, three or five coins together, or run a best-of-3 / best-of-5 match.
Does it store my coin flips anywhere?
Your flip count is kept only in this browser's local storage, so you can track your session — nothing is sent to a server.
Is a virtual coin flip fair for settling bets?
For casual decisions, yes — each flip is an independent 50/50 draw. For anything high-stakes, agree the rules with everyone involved first; FateDecider is for fun and everyday ties.
