Sudoku (数独)is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. But this is an Small-killer Sudoku not a basic Sudoku.
The rules:
In the space filled with numbers from 1 to 6, making the number of each row, each column and each region are not repeated, the number of tips outside of the arrow all oblique direction and digital square.
规则：
在空格内填入数字1～6，使得每行、每列及每宫内数字均不重复，盘面外提示数表示该箭头所指斜方向上所有格内数字之和。
The final coordinates is
N22°39.(A-4)(B-1)(C-4) E114°03.(D+1)(E-2)(F-1)
