规则
从表格左上角的旗帜开始, 画一条环状的路径回到原点。这条路径必须经过表格中除了树以外的每个格子, 且经过有数字的格子时, 必须依照数字顺序。而路径本身只能直向或横向连接, 且不能碰到或跨越自己。
Rule
Draw a trail which starts at the flag in the top left corner of the grid, visits every numbered viewpoint in numerical order, then returns to the flag. Every cell must be visited except for those occupied by a tree. The trail moves orthogonally between the centre of cells and does not touch or cross itself.

解题技巧

  • 由于要按照数字顺序连, 所以就是先将数字用很轻的笔调画淡色的线相连, 观察他们的走法, 就会发现在些数字连起来后会隔开其他数字的连繫, 这时可能就要稍微绕路一下, 大致上的走势看出来后, 就可以解出。
