Coin Flip
Make quick, fair decisions with a true 50/50 flip. Customize your coin and track every result.
🪙 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 Math.random() — a uniform distribution seeded by the browser. Every outcome is perfectly independent. A streak of heads doesn't make tails "due." That's the Gambler's Fallacy, and it's always wrong.
