Ranked replays
Classic and Daily runs record quantized pointer or touch input so the server can reproduce the deterministic simulation and verify the score.
Privacy
Play without an account.
DPI HUNTER uses a guest identifier so verified scores can belong to the same player without requiring email or registration.
Guest identity
A random HttpOnly cookie identifies a guest player. It does not contain your name, email, or physical mouse DPI.

Mouse sensitivity and reduced-effects preferences are stored locally in your browser. Practice scores stay local.
