In a standard sudoku grid, the boxes are numbered by convention from left to right and top to bottom such that the top left box is box 1, top middle is box 2, and so on. Within each box, the cells are numbered the same way. In this puzzle, the boxes have been separated and shuffled around, and it is up to the solver to determine their actual placement in the solution. Each box must have its box number in that position within the box (i.e. box 1 has 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. Fill each box with the digits 1-9 so that when the boxes are restored to their proper positions, each digit appears exactly once in each box, resulting row, and resulting column. Digits in a cage must sum to the indicated number. For a clue outside a box with no arrow, the first X cells, where X is the first seen digit, sum to the value of the clue. ? sums must be deduced by the solver. Sums do not cross box gaps. A clue with an arrow shows the sum of the indicated diagonal. Diagonals do not cross box gaps.
