Sum Skyscrapers Snake

I actually made yesterday’s snake puzzle a couple of months ago, and yesterday when posting it I realised that I have to make a sum variant. Maybe I’ll try a Haido snake next.

I really liked making this puzzle. Because I might have stuck to the theme too much, there’s a tricky step later on in the puzzle but otherwise it shouldn’t be too hard.

Sum Skyscrapers Snake 1


  • Shade some cells to form a snake, an orthogonally connected non-branching path of cells.
  • The snake doesn’t touch itself orthogonally. That is, if you numbered the cells of the snake from head to tail, the only shaded cells directly adjacent to a shaded cell would be the next and previous cells in sequence. However, touching by corners is okay.
  • The numbers outside the grid act as Sum Skyscrapers clues:
    • On a row/column, a segment of n shaded cells is taken to be a skyscraper of height n.
    • A skyscraper blocks visibility of any other skyscraper behind it that’s not taller.
    • Looking from the clue’s direction, a clue tells the sum of the visible skyscrapers’s heights.
