Fun Fact
A truly random 6-digit number has one million possible combinations. That means even a small increase in digit length dramatically raises unpredictability.
Historical Context
Random digits have been used for centuries, from lottery drawings and cryptographic tables to early computer simulations. Modern browsers now provide cryptographically secure randomness, making high-quality random digit generation accessible to anyone without specialized hardware.
