Normal 6x6 sudoku rules apply. Fill the bold outlined 6x6 grid with the numbers 1 - 6 so that each number appears once in every row, column and bold outlined box.

There are two sets of Skyscraper clues outside the grid. Every Skyscraper clue must contain a digits from 1 - 6 (digits may repeat on Skyscraper clues). Digits on the left side count how many digits are 'seen' looking to the right. Digits are visible when they are larger than all digits before them.

Digits above the grid count how many digits are 'seen' looking down. Digits are visible when they are larger than all digits before them.

Thermometers: Digits must increase along thermometers starting from the bulbs.

For clarity, the outer most set of Skyscraper clues 'see' the next Skyscraper clue and the digits in the sudoku grid.
