This puzzle type appeared in World Puzzle Championship 2009 which was 18th World Puzzle Championship, Antalya (Turkey). This puzzle was one of the few puzzles of this type which I created for practice of Indian Puzzle Team participating in World Puzzle Championship 2009. Now I am re-publishing this puzzle as 33rd puzzle in Mini Puzzles Series.
Rules of Skyscrapers Either Or puzzle
Fill in each cell of the grid with digits 1-4, so that each digit appears exactly once in each row and in each column. Each digit inside the grid represents a building with the height of the digit itself. Numbers outside the grid indicate EITHER a)the number of buildings that can be seen by an observer looking into the grid in the corresponding direction, taking into account that higher buildings block the view of lower buildings from the observer, OR b)the height of the first visible building in that direction.
