How Our Coin Flip Simulator Works
How It Works
This coin flip simulator uses cryptographically secure random number generation to ensure fair and unbiased results, closely mimicking the randomness of a physical coin flip.
Instead of using JavaScript's standard Math.random() function, which generates pseudo-random numbers, we utilize the Web Crypto API's getRandomValues() method. This API provides true randomness by accessing the operating system's cryptographically secure random number generator.
Here's how the randomization works:
- We generate a random byte (0-255) using crypto.getRandomValues(new Uint8Array(1))
- If the value is less than 128, it's heads; if it's 128 or greater, it's tails
- This creates a perfect 50/50 probability split, as 0-127 and 128-255 each contain exactly 128 numbers
The result is a truly random coin flip simulation that's as fair as a physical coin toss, making it reliable for decision-making purposes.
