What's Sudoku?

Sudoku, known as well as südoku or su doku is a logical kind of Japanese puzzle.

Rules are simple, it consists of a 9×9 grid, divided in 9 blocks of 3×3, that have to be filled up so all rows, columns and blocks (3×3) contain numbers 1 to 9 without repeating.

You obviously start out with some spaces already filled in. There’s only one possible solution for each sudoku, so be careful!
