Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Killer cages: digits must not repeat within a cage, and must sum to the value in the corner of the cage.

Thermometer: digits along a grey thermometer must strictly increase from the bulb to the tip.

Entroparity lines: the lavender lines act as entropic lines: each group of three consecutive cells along a line must contain a low digit (1,2,3), a medium digit (4,5,6), and a high digit (7,8,9). In addition, digits along a lavender line must alternate between even and odd digits.
