I just hope I stay in the top 10 :Pmacherlakumar commented at 2013-09-21 00:12:36 I am not sure why I read the center as 221 but ended up with a valid solution even for that clue, after penatly found that its 211 and luckliy the fix was smallMellowMelon commented at 2013-09-21 00:39:59 Oh, that 1-4 up top is more constrained than it looked. That explains why I found this one so hard; I went around the middle in the wrong direction...ksun48 commented at 2013-09-21 04:22:37 Okay, I think this has got to be the hardest puzzle so far.Grizix commented at 2013-09-21 08:19:14 Wow, really hard, as I went through a lot of trial & error, I would really appreciate a walkthrough for this one.rajeshk commented at 2013-09-21 08:24:09 I thought that I will not use trail & error in CTC but this puzzle made me to use that.kiwijam commented at 2013-09-21 17:35:27 Walkthrough start: The cell at the bottom-left corner of the centre 112 cannot be filled, because it cannot escape in any direction. This means the other 3 corners of the 112 are all filled.
