Switching Skyscrapers
(Published on 31. January 2021, 17:50 by udukos)
Normal Sudoku rules apply. If there are clues outside the grid on both sides of a row or a column, then they represent a switch clue on one side and a skyscraper clue on the other. If there is a clue outside the grid only on one side of a row or a column, it could be either a switch clue or a skyscraper clue. The identity of the clues in both cases has to be deduced by the solver.
Each digit represents a skyscraper a number of storeys high equal to its value. A skyscraper clue indicates how many buildings can be seen from that direction, where higher buildings block the view of lower buildings. A switch clue indicates the number of switches between odd and even numbers in the corresponding row or column. Note the inequality sign in the grid.
Good luck. Have fun.
Solution code: Column 5 Column 6
