How It Works

The Coin Flip Simulator uses a random number generator to produce a fair 50/50 outcome on each flip. Over many flips, the results converge toward an equal split between heads and tails, demonstrating the law of large numbers.

How to Use
  1. Tap the coin itself or click "Flip Coin" to flip a single coin
  2. Use the multi-flip buttons (5x, 10x, 50x, 100x) for batch flips
  3. View real-time statistics showing heads vs tails distribution
  4. Scroll down to see your full flip history
Probability Basics
  • Single flip: 50% chance heads, 50% chance tails
  • Two heads in a row: 25% (0.5 x 0.5)
  • Three heads in a row: 12.5% (0.5 x 0.5 x 0.5)
  • Law of large numbers: More flips = closer to 50/50 split
Tip: Try flipping 100 times to see how the distribution approaches 50/50. All randomization happens in your browser — nothing is sent to any server.
