Hi, I'm Miguel Arechaga 👋

I'm the creator and developer of MundoSudoku. This project was born from a very simple idea: build a modern site where anyone could play Sudoku for free from any device, with no mandatory registration and a fast, enjoyable experience.

The entire site has been built from scratch using HTML, CSS and JavaScript, with special care given to speed, design and ease of use.

My goal is to keep improving MundoSudoku by adding new features, daily challenges, advanced statistics and many other updates, so every visit is a better experience than the last.
