规则Rules：
标准数独基础上，提示表示从该格起（不包含自身），沿着水平或垂直方向直至盘面外侧，所有数字的和。不过这些和对应的方向顺序未知，且有一些被隐藏。
Classic rules applied. Additionally, the clues show the sum of all the number (doesn't calculate itself) from this cell to the outside in this Row/Column. But we hidden some numbers, and which clue points which direction.
