Place the digits 1-6 once each in every row, column, and irregular region. The grey regions contain the same set of digits in the same arrangement. Adjacent digits on a green line differ by at least 3. Digits on a magenta line form a non-repeating, consecutive set in any order. Digits on a grey thermometer strictly increase from bulb to tip. Digits in a cage do not repeat, and sum to the small number in the top left of the cage. A clue outside the grid gives the sum of the digits along the indicated diagonal. Digits either side of a white dot are consecutive. On a black dot one digit is double the other.
