Normal sudoku rules apply.

Digits in cages sum to the small clue, if given.

Digits in cages are either "water" (7,8,9), "ice" (4,5,6), or "vapor" (1,2,3). Cages may be a single type or a mix of types. Any row within a cage must be a single type and types must be ordered based on their density. Water is heaviest and must be below ice and vapor; ice is heavier than vapor.

Grey lines are "entropic": every set of three adjacent digits along the line must include one water, one ice, and one vapor.

Grey circles contain odd digits.
