Sudoku (El Mundo)

About Sudoku (El Mundo)

El Mundo, the Madrid newspaper, runs four daily sudokus on its games pages. Fácil is for beginners, medio is a step up, difícil is meant for experienced players who want a real challenge, and rápido is a quick grid you can finish in a few minutes. Each level has a new board every day, the same for every player.

The rules are the classic ones: fill the 9x9 grid so that every row, column and 3x3 box holds the digits 1 to 9 once each. The games run in the browser with an advert before the puzzle, and a free El Mundo registration saves your progress across devices. Earlier days stay playable from an archive.

The same pages carry the paper's other dailies: the Crucigrama, the Wordle-style Palabro, Letrerío, a word search, Memory and the ¿Cuánto sabes? news quiz. The sudokus need no Spanish, so they suit anyone who wants a free daily grid at a level of their choosing.

How to play Sudoku (El Mundo)

1. Open El Mundo's games page and pick a sudoku level: fácil, medio, difícil or rápido.
2. Fill each empty square with a digit from 1 to 9.
3. Make sure no row, column or 3x3 box repeats a digit.
4. Finish the grid, then try the next level or an earlier day from the archive.

Tips

• Start with rápido or fácil to warm up, then move to difícil.
• Scan one digit at a time across the whole grid to find easy placements.
• On harder grids, note candidates in each square and look for pairs that rule out digits elsewhere.
