{{BEISPIEL|rooftops}}

''We are looking at a grid of 9x9 boxes. The boxes symbolize buildings with heights ranging from 1 to 9. The objective is to fill in the correct height of each building, considering that each height appears just once in each row and each column. The small digits in the upper left corners of the boxes reflect the amount of buildings the respective building can oversee in its row and column.''

==History==

The Rooftops were invented in October 2017 by [http://www.tppd.de/en TPPD / Thade Precht Playful Design]. A [https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0002QI 9x9 version] is presented in the Puzzle Portal. 

In December 2017, a modification of the Rooftops lead to the related puzzle types [https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0002QJ Low Sums] und [https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0002QK High Sums].
