Sudoku

I just realised how long I haven't blogged. My last latest post was during Christmas & I'm ashamed that I haven't updated for so long. And so, I decided to put up my first completed Sudoku puzzle. It was completed 2 years ago.





Before completing this one, I tried another puzzle. I took 2 hours to solve it but to no avail.





So I took it to school, into my pembangunan insan class & since the students were very very noisy, I taught them what they are supposed to do to solve Sudoku puzzles & gave them a challenge. The first student who can solve that Sudoku puzzle within minutes wins RM5. They all shut up & started to work on the puzzle & I was proud of myself for being able to keep them quiet. =)

I was sure none of them would be able to solve it but one boy did!
