“连数线方块” 作者：James Kopp
这个数独是经典的"James"风格，巧妙但不吓人，当然还足够有趣！
规则：(1) 标准数独规则；(2) 迷雾数独：输入正确的数字可能会揭开某些方格（不一定是邻近的！），不需要（也不允许）任何猜测；(3) 紫色线上面的数字是互不相同的连续数字，每条紫色线连成一个正方形；类似地，灰色线上的数字是互不相同的连续数字，每条灰色线连成一个正方形；用 "X" 分隔的单元格中的数字之和是 10，用黑点分隔的单元格中的数字是 1 比 2 的关系。

Rules:
Normal sudoku rules apply. Placing a correct digit may clear fog somewhere in the grid – no guessing is required. The digits along a purple line contain consecutive digits in any order without repeats. Each purple line is in the shape of a square. Similarly, the digits along a grey line contain consecutive digits in any order without repeats. Each grey line is also in the shape of a square. Cells separated by an X sum to 10 and, in cells separated by a black dot, one digit is double the other.
