Logic9 (Sudoku)

I am surprised that Logic9 on my website is one of the most frequently visited. It rank second to my FAQs.

There are many other websites offering Sudoku puzzles, but it seems that my website has some attractive features. They are:

1. Can play online
2. Easy to play
3. Can play 4 levels
4. Option to choose flowers and letters, instead of numbers.

I shall be updating the website to have more puzzles.

Enjoy.
