Thermo-Skyscrapers (596)
Instruction:
Place the digits 1 through 8 into the empty squares (one per square) so that each digit appears exactly once in each row and column.
Normal Skyscrapers rules apply: each number outside the grid indicates how many buildings can be "seen" from its position at the end of the corresponding row or column, where each number inside the grid represents the height of a building. Larger numbers will block the view of smaller numbers.
The numbers in each thermometer-shaped region must be strictly increasing from the circular bulb to the end. Some thermometers may overlap — the thermometer constraint must be satisfied for each path from a bulb to the end of a path.
Additionally, a thermometer may include space outside the grid. Each such space in the thermometer must be filled with a number that simultaneously satisfies the thermometer constraint and serves as a skyscraper clue. (Note that equal numbers within a thermometer is not allowed.)
