Triangluar Skyscraper: TS1

This puzzle I created for the practice of US Puzzle Championship 2009. This post is special to me as this is my 100th post (including solution posts) on this blog. Still I feel that this the beginning and a long way to go.

Place the digits 1 through 8 into the empty cells (one per cell) so that each digit appears exactly once in each row and column. One digit is given.
The cells in the grid can be thought of as individual buildings, and the number inside the building is the number of floors. A number outside the grid indicates how many buildings can be "seen" from the corresponding direction. (A building is seen by an observer if there are not buildings taller (with a greater number), between it and the observer).

  1. Hey Rajesh,
    Nice to see this variation of skyscrapers. After a long time, i tried any puzzle and it did take long time for me to solve.
    I could do it half-way logically, but finally had to resort to guess-work.
    I found two solutions to this puzzle through guess-work. are you sure this one has unique answer ?

  2. Thanks Aditya for writing your comments. This puzzle is very old I have created. I will try to solve it and see if I can uniquely solve it.

    BTW are you same Aditya, who was the part of Indian Puzzle Team for Croatia?
