Normal Sudoku rules apply. Each row/column begins with a number X, and 1 is the Xth cell of that row/column. Draw Santa’s path in the grid that starts and ends with the two circles. Santa travels orthogonally, and the path may not touch itself orthogonally or diagonally, nor enter the red region, nor contain a 1. Grey cells (houses) are not part of Santa’s path. Their number inside (never 1) indicates how many of the surrounding 8 cells are part of Santa’s path. Not all possible houses are given. Santa’s path totals 165.
