From my understanding many consider Green to be the most challenging to open as far as repeatability. Hopefully my fingers are up to the challenge.

agreed I can't personally get a feel for the puzzle using the trainer it's just not the way I feel comfortable holding the puzzle.maztec wrote:I find the trainer to only be useful if you are trying to get faster, once you know how to open it or get through a section. Otherwise, I like having the fine, up close touch of the maze where I can feel what is going on.
