Sudoku update - LAST

Yes, this is the last update of my company sudoku competition.

I promise!

Yesterday was the so-called Grand final of sudoku game.

The competition had three rounds:
1) finish as many easy grade puzzle as you can in 15 min
2) finish a hard grade puzzle as fast as you can in 15 min
3) fill up as many empty spaces as you can in an evil grad puzzle in 20 min.

After three rounds of neurons-killing games, finally I'd won the first two rounds!!!

Hahaha... they called me sudoku champion!

and the best was I have a S$70 Takashimaya voucher now!! :)
(even though i wish it is cash)

Thanks to those who keep saying "good luck", "加油" and "congratulations"!
