Yes. The result is generated by `crypto.getRandomValues()`, which uses a cryptographically secure pseudorandom number generator (CSPRNG) from the operating system. The probability of heads or tails is exactly 50%.
Coin Flipper
Fair result with a perfect spin
True randomness for quick decisions
This tool uses `crypto.getRandomValues()` — the same cryptographic API your browser uses to generate secure passwords — to ensure heads and tails each have exactly a 50% chance. The outcome cannot be predicted or manipulated. The 3D animation recreates the real spin of a coin in the air.
Three simple steps
- Click the button or press Space to flip the coin.
- The coin spins in the air with a realistic 3D animation.
- The result (heads or tails) is displayed along with the history of recent flips.
