I recently got drawn in by this quirky maths game called Sudoku. Here is a quick description of the game from Wikipedia:

The aim of the canonical puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called “regions”), starting with various digits given in some cells (the “givens”). Each row, column, and region must contain only one instance of each numeral.

The day before I had to show up at the Victoria County Court in Melbourne for my Jury Service, Raquel and I dropped by the local bookshop (as usual) and I happened to come by a rack of books dedicated to Sudoku. I was mildly curious so I read the first few pages just to understand how the puzzle works.

I found out that it wasn’t too difficult to play, actually. It just involved a lot of lateral thinking, especially on the more difficult puzzles. When I finally understood how to play the game, I got hooked.

I printed out pages of the puzzles and even brought them to Jury Service the next day so that I had something to do while waiting to be enpaneled. A good thing, too, because I spent most of that day just solving the sudoku puzzles I brought along.

I think I may have overdid it for the past few days though because, now, I no longer hold much interest in it. Still, I recommend you give sudoku a go. It’s a fun way to pass the time.

You can get your fill of sudoku puzzles from the following sites:

- Sudoku Fun (I found the ladder puzzles very challenging.)
- Fiendish Sudoku
