Sudoku

All of us in office are fanatical about the Sudoku for these few days! Of course, we played secretly. I managed to solve the Sudoku for the first day, but I knew the one should be intermediate level only. Today, it comes in advanced level. So hard!!! I've tried my best and erased the paper for thousand times, and I'm failed to solve!! :( All girls failed, the only guy made it! I don't want the foolish punishment!!!

This is the sample for CLASSIC Sudoku...is very good for brain! :P

Foolish punishment - eat different number of cookies depends on your speed to pass up and etc. My boss shouldn't give us the cookies for CNY, now it seem like torturing us more....*cry*
