This page explains the website. App Store, Google Play, and Steam links are empty until those apps are released.
Solo
Open Solo to play. Digits you enter and notes stay in this browser, including after a refresh. “This level” starts the current puzzle over and replaces that saved progress.
Online
Online play needs the sudoku server. The guest session, gold, and diamonds stay in this browser. A server restart clears in-memory accounts, so you enter again.
Hints
Hints reason from the current grid only. They mark a cell that can be deduced and do not fill it for you.
Not released yet
There is no mobile or Steam download yet. Use this website for now.
