How It Works
This coin flipper uses crypto.getRandomValues() to generate a cryptographically secure random bit for each flip. The result is perfectly fair with a true 50/50 probability.
Statistics are tracked in real-time: total flips, heads count, tails count, percentages, and your current streak. Over many flips, you should see the percentages converge toward 50% -- a demonstration of the law of large numbers.
Use it for making quick decisions, settling disputes, or demonstrating probability concepts.
