Logic Masters Deutschland e.V.

• Normal sudoku rules apply.
• Yin Yang: colour the grid using two colours, such that all cells of the same colour are orthogonally connected, and no 2x2 area is fully one colour.
• Skyscrapers: clues outside the grid indicate how much digits in the grid can be seen from that direction, where higher digits block lower digits from view.
• Coloured Skyscrapers: each skyscraper clue only sees digits of one yin yang colour, while digits of the other colour are completely meaningless for that clue.
Which colour corresponds to each clue must be determined.

Note: you may place colours or labels outside the grid to assist your solve. Those won't interfere with the solution checker.

Have fun and keep flutchin'.
Yours, Dying Flutchman
