True. However, the 10*10 solution where you use all the four tangle puzzles to form a 10*10 pattern with matching edges, has been found to be impossible( Although the puzzle leaflet says that it is solvable). Once again there is no 'insightful' solution.

There have been some interesting postings in this group on this topic in the last few weeks and you should read them . > However, I haven't seen anyone who claims to have come up with an > "insightful" solution, i.e. one in which you figure out a general > approach that leads to a solution.
