Use this free online coin flip tool to instantly flip heads or tails. It is perfect for making quick decisions, playing games, settling debates, or choosing between two options.
🪙 Click the coin or press Space to flip.
🎯 Popular Use Cases
Flip a coin whenever you need a fast, unbiased answer. Sports teams use it to decide kick-off, friends use it to settle who pays the bill, and developers use it to break a tie when no option clearly wins.
🪙 How It Works
Click the coin or press the Flip button for a random result. Customize the labels on each side, choose a coin style, and track your session with live stats and a flip history. Press Space as a quick keyboard shortcut.
⚖️ True 50/50 Probability
Each flip uses the browser's crypto.getRandomValues() API when available, with a legacy fallback for older browsers. Every outcome is independent. A streak of heads doesn't make tails "due." That's the Gambler's Fallacy, and it's always wrong.

Frequently asked questions
Is the online coin flip fair?
Yes. Each flip uses your browser's cryptographic random number generator, giving heads and tails an equal 50/50 chance with no bias or memory of previous flips.
Can I rename heads and tails?
Yes. Use the label fields to name the two sides anything you like, such as Pizza and Tacos, then flip.
Does the coin remember my streak?
Your session stats and streak are tracked in your browser only. Each individual flip is still independent, so a streak never makes the next result more or less likely.
