Rules: Normal sudoku rules apply.

Clue ambiguity: The clues in the grid are either killer clues or look-and-say clues (or both). It is up to the solver to determine which clue is which. The definitions are below:

- Killer clues (Standard rules): Digits cannot repeat in cages and must sum to the number in the top left corner of the cage. For diagonal clues, digits along the diagonal must sum to the number pointing at the diagonal. Digits may repeat on the diagonal if allowed by other rules.

- Look-and-Say clue: Digits MAY repeat in cages and along indicated diagonals. The clue should be read as a "look-and-say number". Each number says which digits are in the respective cage or on the respective diagonal. For example, if a cage clue is 12, this means there is 1 two in the cage. If a diagonal says 33, then there are 3 threes along the diagonal.
