Rules:
1) Normal Sudoku rules apply, place the digits 1-9 in each row, column and 3x3 box once each.
2) Digits separated by an X must have a sum of 10.
3) Outside Clues are always one of the following, but never both;
a) Full-Rank: Read each row and column of the grid from both sides, and rank them from lowest to highest. An outside clue is the ranking of its corresponding row or column from the direction of the clue itself.
b) X-Sum: An outside clue indicates the sum of the first "X" digits where "X" is the first digit seen in that direction.
4) For outside clues with the same value, one of them must be a full-rank clue.
