About Sudoku (Observador)

Observador is a Lisbon-based online newspaper, and its games section includes a daily sudoku alongside the word game AbraPalavra and the logic puzzle SudoCrime. Every day the site publishes three new grids, one at each level, and all players get the same ones.

The rules are the classic ones: fill the 9x9 grid so that every row, every column and every 3x3 box holds the digits 1 to 9 exactly once, with no repeats. You choose a level from a menu (Fácil, Médio or Difícil) and can switch to another level when you finish.

The game runs in the browser with no account. It can be paused, restarted, and keeps a record of your best results; when you finish you can copy your result to share it, and a countdown shows when the next game arrives. The interface is in Portuguese.

It suits sudoku players who want a short, dependable daily set of three grids, and Portuguese readers already using Observador's games.

How to play Sudoku (Observador)

  1. Open observador.pt/jogos/sudoku and choose a level: Fácil, Médio or Difícil.
  2. Select an empty square on the grid.
  3. Enter a digit from 1 to 9 that does not already appear in that row, column or 3x3 box.
  4. Repeat until every square is filled correctly.
  5. Copy your result to share it, then try another level.

Tips

  • Start with rows, columns or boxes that already have the most digits.
