Sudoku Competition

Recently, I participated in the Sudoku competition organized by Science and Mathematic Society. The Sudoku is quite simple. Thus, I am stuck at the 2nd puzzle. OMB!! I dunno y i did not realise that 2 boxes can be solved. And this has taken my time. T.T

Even though my chance to grab a prize is low, but I won’t be upset cause it is just a small challenge for me. There are tougher challenges waiting for me.
Gambateh!!
