Is it really 50/50?
Yes. Each flip is an independent, cryptographically random bit. Streaks happen naturally: in 100 flips, a run of 6 or more of the same side is more likely than not.
Frequently asked questions
Is this truly random?
It’s cryptographically secure pseudo-randomness seeded by your operating system’s entropy, which is unpredictable for any practical purpose including draws and games.
Can I generate numbers without repeats?
Yes. Tick “No repeats” and the numbers are drawn without replacement, like a lottery.
What’s the largest range?
Up to about 9 quadrillion (2⁵³) for single numbers. For no-repeat draws, the range must be at least as big as the count.
