Akkara Loop: A1

This is the first puzzle of this type which I created for practice of Indian Puzzle Team participating in World Puzzle Championship 2009. I have created some more puzzles of this type, which I will be posting here later. Akkara Loop Puzzle appeared in "18th World Puzzle Championship, Antalya (Turkey)".
