What is the difference between random and pseudorandom?

Truly random numbers come from physical processes (radioactive decay, thermal noise). Pseudorandom numbers are deterministic sequences that appear random. For most uses, pseudorandom is sufficient.

Can I use this for lottery picks?

Yes! This generator uses cryptographic randomness, making it as fair as a physical drawing. The generator has no memory of previous results — each number is completely independent.

What is a seed in random number generation?

A seed is the initial value used to start a pseudorandom sequence. The same seed always produces the same sequence — useful for reproducible experiments. Our generator uses a fresh seed each time from the system clock.
