Rules for this puzzle:
1. Normal sudoku rules apply.
2. Clues outside the grid give the sum of the X first cells seen in the direction of the clue, where X is the value of the first cell.
3. There are exactly fifteen friendly cells in the grid. (A friendly cell contains its row number, column number, or box number; numbers are assigned left to right and then top to bottom.)
Happy Solving!!!
