Coin Flip uses the Web Crypto API's cryptographically secure random number generator to produce fair, unbiased virtual coin tosses. It supports single flips and batch mode for running hundreds or thousands of flips with real-time frequency distribution tracking. The tool displays a running tally of heads vs tails with percentage splits and chi-squared statistics to verify randomness quality. An animated coin provides visual feedback for single flips.
Probability students running experiments, game designers testing randomization logic, and teams making quick decisions during planning sessions. The tool runs entirely in your browser — your data never leaves your device.
