SUDOKU puzzles have become quite popular. Solving the puzzles is fun and is also good mental exercise. However many people just don’t ever try them, or they give up easily if they do. One reason is that it’s hard to keep track of all the number possibilities, particularly for the more difficult puzzles.
Sudoku is a logic puzzle that became very popular in a few months all around the world. One can find sudoku puzzles everywhere: in the subway, in trains, in buses, in classrooms, in very serious newspapers (eg. Le Monde in France or The Times in the UK).
It is truly a game for all ages: from kids in preschool to seniors. Sudoku has a lot of intellectual stimulation virtues that promote its usage in different contexts: schools (as an initiation to mathematical logic), universities (as a support for computer science related courses), etc.
The rules of the Sudoku game are simple:
- an 81-cell square grid is divided into 9 smaller blocks made up of 9 cells each. Some of the 81 cells are already filled (they are often referred to as given).
- The aim of the game is to fill all the empty cells with one digit from 1 to 9 in such a way that a digit does not appear twice in the same row, or in the same column, or in the same block.
- There is a single solution. If it is not the case, the grid is called “invalid”.
