Pseudo vs. Cryptographically Secure RNGs
Most software programs utilize simple pseudo-random number generators (PRNGs) like Math.random() in JavaScript. These use deterministic formulas that take a seed value and return a sequence. While fast and suitable for basic UI animations, PRNG sequences repeat eventually and can be predicted, making them unsafe for drawings.
To resolve this, our randomizers retrieve random seeds via the browser's native Web Cryptography API. This connects directly to operating-system-level entropy (e.g. system noise or hardware state). This ensures that every generated number is mathematically unpredictable, uniform, and fair for draws, science models, and games.
