Rules: Normal sudoku rules apply. Along thermometers, digits must increase from the bulb to the tip. Digits along arrows must sum to the digit in the arrow's circle.

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

- Killer cages: Digits cannot repeat within a cage and must sum to the number in the top left corner of the cage.

- Look-and-Say cages: Digits CAN repeat in these cages. The number in the top left corner should be read as a look-and-say number and says which digits are in that cage. For example, if a look-and-say cage has the clue "12" then it means there is one 2 in the cage. If it has the clue "33" then it means there are three 3s in the cage.
