Today's Akkara Loop is the first puzzle of this type that I created for the Indian Puzzle Team's practice ahead of the World Puzzle Championship 2009. I have created more of these puzzles, which I will post here later. Akkara Loop Puzzle appeared in "18th World Puzzle Championship, Antalya (Turkey)".
