How product pages are organized

Each product gets its own page because the user expectations are different.

Separate product promises

Each product page explains its own status, audience, support path, and privacy expectations so users do not need to infer details from a generic company description.

Low-friction use

Sudoku emphasizes no sign-up and offline play. Future products will follow the same preference for direct workflows and clear controls.

Plain support routing

Product questions, bug reports, policy requests, and store-purchase questions point back to one visible support address.
