Sudoku (Público)
Público's daily sudoku, from easy to very hard.
Every day: Dated sudoku grids each day, the same for every reader, at levels from easy (Fácil) to very hard (Muito difícil), with a timer, hints and an archive. New puzzle: Once a day.

Público's Sudoku offers dated daily grids at several difficulty levels. You fill the 9x9 grid so every row, column and 3x3 box holds the digits 1 to 9 once. There is a timer, a hint button and an option to give up or restart.
About Sudoku (Público)
This is the daily sudoku on the Portuguese newspaper Público's games page. Each day's grids are dated and the same for everyone, and you can choose a difficulty from easy to very hard.
The rules are classic sudoku: fill the 9x9 grid so that each row, each column and each 3x3 box contains the digits 1 to 9 exactly once, starting from the given numbers.
A timer starts when you begin. You can ask for a hint, restart, or give up to see the solution, and earlier days are available in the archive. The interface is in Portuguese, but the puzzle itself needs no language.
Público keeps its daily games for registered readers: a free account is enough, and the page asks you to register or sign in before you play.
It suits sudoku players who want a daily grid at a level of their choosing.
