这是博客文章9，其中详细介绍了我的冒险历险记 活线 in Canada!!! These last 4 are supposed to be the most 难 they have on their site (all level 10). I start with the 松树 puzzle. This is another member of the 梯形环 group of puzzles and is very old in it'的设计。这些原件来自中国，形状像宝塔。这些来自加拿大，因此形状像国家树！！！
"Anyone 在 tempting this puzzle should be warned that 在 tention to detail is required, since the path leading to the removal of the cord is 难 to distinguish from the paths which will lead you astray."
