Normal sudoku rules apply. Place nine digits along the line. A digit X in position Y requires a digit Y in position X. (Position 1 being on the far left diamond, position 9 on the far right tip.) Digits on the line are skyscraper clues, i.e. they indicate how many digits in the column are larger than all digits lower down in the column. The grey area sums to an even total.
