This puzzle was accidentally published in the end of December, dated at December 8th. I caugth on to that a couple of days later and deleted it. So some of you may have already seen it, or even sloved it. Sorry for the mix-up.
החידה הזאת פורסמה בטעות בסוף דצמבר עם התאריך 8 בדצמבר. קלטתי את זה אחרי איזה יומיים ומחקתי. אז חלקכם אולי כבר ראיתם ואפילו פתרתם אותה. סליחה על הבלבול.
Rules:
Fill in the grid, so that each row and each column contain all of the numbers from 1 to 6. The numbers inside the grid represent skyscrapers of those heights. A number next to a row or column, indicates how many skyscrapers from that row or column can be seen from that position. Taller skyscrapers block the view of shorter skyscrapers that are located anywhere behind them. There is a unique solution to the puzzle.
