It's interesting playing the puzzles that have line of symmetry. For instance, Nis' Tree of life.
At this point the next step was forced by the puzzle having a global line of symmetry. Legitimate solving technique or cop-out? |

Using absolute symmetry is just like using a uniqueness test. If the clues have absolute symmetry, the solution also has to otherwise there would be multiple solutions. |

My _first_ move is to put in the only possible line on the 1, followed by the other line on the two, and then it's solved.

Legitimate solving technique for a poorly-designed puzzle.  |

I'm not always quick to spot things like that. So I started working from the patterns I could see and then I realised the symmetry thing..
Perhaps I shouldn't have revealed my flawed techniques quite so readily. |
