Sudoku
Fill the board without repeating numbers
About this game
Sudoku is one of the most studied logic games: to complete the board, you need to rule out possibilities and compare rows, columns and blocks at the same time — a direct exercise in attention and planning, with no luck involved.
On DIVILLI, you choose the level (Easy, Medium or Challenging), can turn on "Notes" to jot down candidates in a cell without committing to them, and use "Hint" whenever you get stuck — with no mandatory timer pushing you along.
FAQ
Is Sudoku good for the brain?
Sudoku exercises logical reasoning and sustained attention, skills linked to cognitive reserve. It doesn't prevent disease, but it's an enjoyable way to keep your mind active on a regular basis.
Which Sudoku level should I start with?
Easy, already marked as recommended, is the ideal starting point — it has more numbers already filled in. Move up to Medium or Challenging as you gain confidence.
