Sudoku – Resolution Techniques

What makes Sudoku puzzles so attractive as a pastime? There are trillions of possibilities in this entertainment. They can be easy, medium, difficult, or extremely difficult to solve.

Usually, people start with the easy ones and fall in love with them, and over time, they learn new techniques and challenge themselves with the harder Sudoku puzzles.

As a chemist with a focus on exact sciences, I learned over the years about the techniques, both in books and specialized websites, and I felt the absence of a website in Portuguese that treated this pastime in a light way, without the pedantry that some authors try to use, which often makes it difficult to understand techniques that are mostly simple.

There are two ways to navigate the website. One is for beginners, the COURSE (free), which means following the techniques in sequence, and the other is for others to look for specific techniques in the menu on the side.

A little bit of history.

Why is the website “.eco.br”? My background is in the environmental field, and I have a BLOG about the environment. Blog Mauro Moura
