Skyscraper Sums
- XV and number dots
The brief
Normal Sudoku rules apply. Digits with a "V" between them sum to 5. SKYSCRAPER SUMS- Numbers in the grid represent a building of that height, at that location. Higher buildings block the view of all lower ones behind them. Numbers outside the grid are the sum of all building heights that can be seen, looking orthogonally into the grid, from that location. NOTE: Be careful. The numbers in conflict do not turn red, to allow me to use numbers outside the grid for the purpose of skyscrapers.
