About Coin Flip

This virtual coin flip uses cryptographic randomness (crypto.getRandomValues()) to ensure a fair 50/50 result every time. An animated flip adds to the experience, and the statistics tracker shows how actual results compare to the expected 50% distribution over many flips.

Features

  • Animated flip - 3D CSS coin animation for each flip.
  • Statistics - Tracks heads count, tails count, total flips, and heads percentage.
  • Bulk flip - Simulate up to 1,000 flips instantly to see distribution.
  • History strip - Visual strip of recent results.

How to Use

  1. Click the Flip button - the coin animates and lands on Heads or Tails.
  2. The result is added to the History Strip below the coin.
  3. Use Bulk Flip to simulate up to 1,000 flips instantly and see the statistics.
  4. Click Reset to clear the history and start fresh.

How It Works

Each flip uses crypto.getRandomValues() to generate a cryptographically random value. A single random bit is extracted - 0 for Heads, 1 for Tails - ensuring a perfectly fair 50/50 result every time.

Example

Use Bulk Flip with 1,000 flips to verify the 50/50 distribution. After 1,000 flips you should see approximately 500 heads and 500 tails - the statistics panel shows the exact percentages.

FAQ

Yes - the results are cryptographically random and unbiased, making them suitable for fair decisions. However, for official or legal proceedings, consider a witnessed physical coin flip.
