I bet everyone has heard about ‘Sudoku’. It is a mind puzzle game which you have to rack your brain to try putting numbers 1-9 into their position in the board (usually 3x3x9) without repeating in a row/column/box.
My sister loves it and is very good at it. I was not as good and I always got stuck somewhere then (I am not so proud of this) I sometimes just gave up and handed it over to my sister to complete it.
Surely, I quite enjoyed Sudoku but not yet ‘addicted’. Until I found this levelled up more challenging improvised Sudoku called Killer Sudoku. Tried this once and got frustrated by its complexity, but after struggling for a few times solving some I am hooked. Now I am craving for more. I even purchased some killer sudoku’s series and spend most of my time staring down at the puzzle while holding my pencil, frowning and scratching my head.
Nevertheless, I can not do it. This is so addictive.
Anyone up to a challenge, you can give it a try at http://www.killersudokuonline.com/. They have daily, weekly and different difficulty puzzles. You can play it on line or you can print it out and play it off line.
