Fair randomness

Draws, teams and brackets use your browser's cryptographically secure random number generator with unbiased shuffling, the same kind of randomness used for passwords, so every outcome is equally likely.

Frequently asked questions

Is the randomness fair?

Yes. Team splits, draws and brackets use your browser's cryptographically secure random number generator with unbiased shuffling, so every arrangement is equally likely.

Is the test data real?

No. Names are common names combined at random, emails use the reserved example.com domains, and US and UK phone numbers come from ranges reserved for fiction. Don't use generated data to contact anyone.

Is anything I enter saved?

No. Everything runs in your browser and nothing is uploaded.
