While SuDoku debuted in Japan in 1986, international interest in the game gained new heights in 2005. Now more and more local newspapers are starting to print out these puzzles so the public can take to work everyday and not end up getting bored after reading the paper.
These are the rules of SuDoku:
- Sudoku is played over a 9x9 grid, divided to 3x3 sub grids called "regions".
- Sudoku begins with some of the grid cells already filled with numbers.
- The object of Sudoku is to fill the other empty cells with numbers between 1 and 9 (1 number only in each cell) according to these guidelines: a number should appear only once in each row, column and region.
I admit I've been hooked on this puzzle ever since I discovered it in a Toronto Metro newspaper back in July.
