Had to leave my started puzzle unattended for a while...
I remeber that these Hanjie Puzzles were doable with only single-line-logic.

Where did I miss it in this puzzle?
I needed 2-dim-logic to get started, then it was smooth - but I missed something at one point...

Don't get me wrong, I like these puzzles, (especially if you don't have an advantage if you just draw what you expect...)

I just wondered.

I don't know if you will ever see this, Joerg... but I started in the fifth column from the right hand side (that was 1, 10, 9). Those numbers added together are 20, plus at least one each for the gaps between those strings makes 22. The puzzle height was 30, so that meant there were 30-22 = 8 spaces at most that each colored string could bounce around in. Since one string was nine long, that meant no matter where it was, that ninth square up from the bottom would always be colored. And since one string was 10 long, that meant that no matter what, the eleventh and twelfth squares from the top were colored (since the 1 string and a gap have to exist above the 10 string). With those three squares colored, I then looked at their rows. The last strings in their rows were a 9, a 10, and a 6... all which would continue further to the left than the currently colored square. So I colored more squares... and back and forth...

Hope that answers your question / helps.

Hi vivayossarian...? (Don't know what a first name might be :-)
That's exactly what I was looking for, and I completely missed this column. Thanks! I just knew there should be one. And a while ago I had the same problem, and I thought about a new pattern. But maybe I'm just getting old.

I finally started putting white squares in the first and in the last row, indicating, where the 3 and 4 couldn't be. There are enough those "non-black" positions: you would have more than 1 or 2 adjacent black squares in rows 2 and 29, in row 29 especially on the right... That's how I decided where it had to be white (I hope this makes sense...)

In the end those gaps in row 30 were small enough to put the right 4 in. And then I probably used the 5th column anyway without noticing...

Glad I could help!

Your strategy makes sense to me--and it is definitely something I do when I get stuck too!

  • A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
  • Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
  • If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
  • Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
