Normal sudoku rules apply (fill each row, column, and 3x3 box with the digits 1-9 once each), and all clues are standard.

Killer cages: the sum of the digits inside each cage is equal to the small number in the top left corner (if given), and digits cannot repeat within a cage.

Digits in cells separated by a white dot are consecutive.

Digits in cells separated by a black dot have a 1:2 ratio.

Draw the path that Santa Claus takes on Christmas night, starting and ending at the North Pole (the killer cage in Box 2). The path moves orthogonally and may never cross itself. Santa must land on each of the continents (the other 6 killer cages) exactly once. In order to land on a continent or the North Pole, Santa must enter a low polarity cell (1,2 or 3) at some point on his path. At all other times when passing over a continent, Santa must stay in high polarity cells (7,8, or 9) to avoid being seen. When traveling over oceans, Santa must travel through medium polarity cells (4,5, or 6) so he does not get lost.
