Some say a rolling stone gathers no moss, but a rolling snowball just gathers more snow.

Rules:

Normal Sudoku Rules apply: The digits 1 to 9 must appear in every row, column, and 3x3 box.

Snowballs: There are eight snowballs in the grid marked by light blue circles. Each snowball rolls in a straight line through a set of orthogonally connected cells. The total length (in cells) of a snowball’s path is given by the number in the top left corner. The digits along a snowball’s path behave as follows: after the first two digits, each digit is the sum of the two preceding digits (just like the Fibonacci Sequence). Snowballs may cross paths, and therefore may share one or more cells with other snowballs.

Below is an example of a length 5 snowball that starts at 2 and ends at 7. The digits 3, 4, and 7 are each the sum of the two preceding digits: 3=1+2, 4=3+1, and 7=4+3.
