This Puzzle Doubles Back as a practice puzzle for Chennai Brain Games ( http://www.chennaibraingames.in ) held this weekend.
Sometimes, you think, “Ok, thats exactly what I want, I’m gonna get that done”. Sometimes, you think “I’m so tired, let me just try the first thing that pops into my mind and see if it sticks”. Unfortunately, this is the latter. Why am I so busy? That’ll still have to wait. Hopefully I can do a full post on it when I get back home next week.
Double Back rules. I’m sorry, but I don’t have the time/energy to make it color based right now, region based will have to do.
Rated – Medium. (with a lot of little intricacies)
