About the game
Played in the browser, on your phone or computer, at play.indexhub.it.
- Four levels set by the technique you need, not by how many cells are empty. Every grid has one solution and can be solved by logic.
- The daily sudoku is the same for everyone: easier early in the week, hardest on Saturday.
- Hints that teach: first where to look and which reasoning to use, only then the number.
- Pencil notes, unlimited undo, mistakes marked right away (can be turned off), full keyboard support.
- Works offline; streaks, records and achievements stay on your account.
