OMG, was trying to find the right ranks and files, but was several steps away, for a long time. Today I came two off and after a few more tries finally found the 218. Great LEVEL!
OMG! There's a ''devil'', optically. I had to try at least 5 times, and was always short. At 1st, I was 2 short, then even more. HAHAHAH! Usually, on this kind of levels, I just look for half a minute and solve it 1st try.
