About Coin Flip
A genuine 50/50: each flip draws from the browser's cryptographic random source. Flip one coin to settle a decision or a hundred to watch the law of large numbers in action — the running tally tracks heads, tails, and percentages across flips, and each batch reports its longest streak.
Common uses
- Settle a two-way decision fairly
- Demonstrate probability and streaks for a stats class
- Simulate many trials quickly without a pocketful of change
