My sis has this craze about sudoku that she plays her daily sudoku games at http://games.yahoo.com/console/sudokudaily
For me, I'd only do it once in a while to 'exercise' my brains.
She was shouting that she completed her 5 star sudoko.
That pressured me to complete and voila!!
I did it too!!
PRoveeeeeeee... screen shot of my completed game!
It was perhaps, 2 years back, I was introduced by one of the shift supervisors in my previous job about this game. I was kind of amazed with this mind game and truly liked it.... as it really test the way my brain works.
In fact, my colleagues and I were playing during our night shift... and tried competing with one another who finishes first. :D
