Ok, I have a riddle to you, if someone is still interested...

You need to put 1-12, one number over each line, so that the outcome of every 4 numbers in the... errr... bigger lines, would be equal everywhere.

(this is obviously wrong.)
(I think there's more than one right solution)

Edit - it doesn't work well. .
In entmoot, I guess that if you put blanks it automtically writes it in the side. Never mind...
Anyway, it should be like the sign on my avatar... When each line in made of 4 little lines. and above each you put a number.
