 I am having a lot of trouble tackling ones with all 2's.  User puzzles #59, 26, 15 are three such puzzles.  Does anyone have tips on solving these ones?  Usually I have to make a guess which starts unraveling the puzzle but usually ends unfavourably.

 this format make the hardest puzzle in the world by using close loop rule(because it has most solutions if there's no close loop rule, really a big bug). I think 6x6 is already enough for human so I make #22 and with devilish rating. So if you see a puzzle with mainly 2's, ignore is the best choice, just a bug formed by a rule made by a human.
 So if a difficult puzzle by using rules other then close loop rule is made, it should be a very great puzzle!

 It's easy if you assume this puzzle's solution is unique,
 it's hard if you want to prove for its uniqueness.

 where is it?

 | Posted - 2007.05.12 08:16:19 Jankonyex, can you describe what is the "closed-loop rule" you are referring to?  I can guess it has got to do with not closing a loop too early... is there anything more to elaborate?
 
 Thanks again.
