Flip a Coin

Need to settle a debate or make a quick decision? Our coin flipper gives you an instant, unbiased heads or tails result with a satisfying flip animation. Every flip uses cryptographic randomness for a perfectly fair 50/50 outcome.

When to Use a Coin Flip

Use a coin flip when you need a quick binary decision, want to settle a friendly dispute, or need to randomly assign two options. For decisions with more than two options, try the wheel spinner instead. Also useful for probability demonstrations and statistics lessons.

Coin Flip Tips

  • Watch the streak counter — a streak of 6+ heads in a row happens roughly once every 64 flips.
  • If you are disappointed by the result, go with the opposite — the coin revealed your true preference.
  • For best-of-three decisions, flip three times and go with the majority result.

Frequently Asked Questions

Is the coin flip truly random? ▾

Yes. We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure randomness — more fair than a physical coin toss, which can be biased by technique.

What are the odds of heads vs tails? ▾

Exactly 50/50. Unlike a real coin which can have slight manufacturing bias, our digital coin flip is perfectly balanced.

Can I use this for making decisions? ▾

Absolutely. A coin flip is one of the most time-tested decision-making tools. If you find yourself disappointed with the result, that tells you what you actually wanted.

What does the streak counter show? ▾

The streak counter tracks consecutive heads or tails results. Streaks of 5+ are uncommon but perfectly normal in random sequences.

Does the coin flip work on mobile? ▾

Yes. The animated coin flip works on all devices — phones, tablets and desktops. No app download needed.
