Grille de la semaine #170

Two puzzles this week, to make up for last wednesday's hiatus. The Diagonal Sudoku (round 1) is reasonably easy, the Sum Skyscraper (round 3)... not so much. This last one was the hardest puzzle I contributed to the French selections, only beaten by Timothy's Little Killer Sudoku. Both ended up being correctly solved by only three people, so good luck trying to make your way into it.

Règles :

Chaque ligne, colonne et région, ainsi que chacune des deux grandes diagonales, doivent contenir les chiffres de 1 à 9.

°°°°°°°°°°°°°°°°°°°°

Each row, column and region, as well as each of the two main diagonals, must contain the digits from 1 to 9.

Chaque ligne, colonne et région doivent contenir les chiffres de 1 à 9.
Chaque chiffre de la grille correspond à un gratte-ciel dont la hauteur est égale a ce chiffre.
Les indices extérieurs correspondent à la somme des tailles des immeubles visibles, sachant qu'un gratte-ciel dont la hauteur est supérieure à un autre masque celui-ci.

°°°°°°°°°°°°°°°°°°°°

Each row, column and region must contain the digits from 1 to 9.
Moreover, each digit inside the grid is a skyscraper of the corresponding height. An outside clue corresponds to the sum of the heights of all skyscrapers which are visible in its row or column, starting from this point, knowing that a skyscraper which height is superior to another masks this last one.
