Level 233
Posted: Tue Sep 18, 2018 8:27 am
I am stuck here for a very long time, I must have some problem in reasonning ... I have reduced the problem to size 13*23 (and checked it manually) ... and I am almost sure there is no solution ... 
...
but as several people passed the level ... I must be wrong. I have returned to the puzzle after the very long time, may be, I will find the gap in the reasonning.
.... I just hope there is only one variant of the puzzle and not more with one unsolvable.
