Skyscrapers (Tight Fit) by Roland Voigt

Skyscrapers by Roland Voigt

PDF

Theme: Equal Distribution and Symmetry of Clue Numbers

Author/Opus: This is the 2nd puzzle from guest contributor Roland Voigt.

Rules: Standard Skyscrapers rules. Also, some cells have been split into triangles, each of which must be filled with a number. In this puzzle, the numbers 1-5 must be placed in each row and column.

(The split cells are viewed in the order they are seen from a given direction, so the upper triangles are seen first from the left/top sides and the bottom triangles are seen first from the right/bottom sides.)

Answer String: Enter the 1st row from left to right, followed by a comma, followed by the 3rd row from left to right. Enter the split cells in the order they are seen from the left (the upper triangle before the lower triangle).

Time Standards (highlight to view): Grandmaster = 0:40, Master = 1:15, Expert = 2:30
