2. Little Killer: For every clue outside the grid, digits along the indicated diagonal sum to the given number.
3. Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
4. Killer Cages: Digits cannot repeat in cages, and must sum to the value in the top-left corner if given.
5. Each cage must be fully shaded or unshaded. Each shaded cage must sum to a prime number. Each unshaded cage must sum to a square number.
6. Each cage has a unique sum (ie there cannot be two cages which sum to 9).
