变型名称:Mine Field Sudoku 地雷阵数独
变型规则:Fill the grid with digits 1 through 6 and three “Mines” (using “X” represent a “Mine”), each row, column and thick outlined grid contain all digits and three “Mines” without explosion. If there are four “Mines” in a group in connection(not diagonally connections), an explosion occurs.
请在以下空格内填入1-6和三枚“地雷”(均用“X”标示)。每行、每列、每宫内数字不重复且恰有三枚“地雷”,且不引发爆炸事故。如果有至少四枚“地雷”连接成一整体(不包括倾斜相接),将引发地雷阵爆炸。
