or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)
Theme: City Center
Author/Opus: This is the 97th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Standard Tapa rules. Also, numbers outside the grid show the number of separate wall segments visible in that direction. A segment of length N in a given direction is taken as a building of height N. Buildings of height N block the view of all buildings behind them of equal or lesser height.

Very nice blend of Tapa and Skyscrapers logic in this one. I particularly like the way the skyscrapers logic is applied to very different style of puzzle, making for some interesting deductions along the way.
