Normal sudoku rules apply - but the grid has been torn apart and scrambled. The clues outside the grid indicate the sums of the contiguous runs of digits found in that 3x3 box's row/column- these digits must be shaded. There must be an unshaded cell between runs of shaded cells. If a row/column is unclued, there is NO shading in that row/column. 3x3 boxes are numbered by convention from left to right and top to bottom such that the top left box is 1, top middle is 2, and so on. Within each box the cells are numbered in the same way. Each box must have its box number in its correct position within the box (ie box 1 of the untorn sudoku has a 1 in position 1, box 2 has 2 in position 2, etc). NO other digit in any box may be in its self-numbered cell. When finished, the shaded cells create a picture if put together in the correct order.
