Like the others, this comes in the standard Puzzle Master clamshell packaging with the instructions to just remove the ring and shuttle. It is supposed to look like a dinosaur but I do struggle to see the likeness. Puzzle Master have rated this as a 10 out of 10 (Mind Boggling) on their difficulty scale and despite having done the others, I have to agree with them. This is one tough puzzle!!! No solution is provided but if you need one (and you might!!) then it can be downloaded from here.
Just like the previous Hess puzzles the exit point is very visible and nigh on impossible to get to. You know where you want to go to but cannot for the life of you find the correct path to get there.
I think that this one must have taken me several hours to solve. Having solved the other two, I knew what was required but apart from the exit point the actual solution is totally different. In fact having done the previous two, I was really no further forward at all! Only after a very long time fiddling did I find a new technique possible in this one. It is not at all intuitive and hence very worth its grade. One of the reasons for my delay and a reason for criticism is that the last part of the critical move requires a modicum of force. This was enough to make me doubt whether I had done it correctly. Despite holding the 3 pieces in my open palm, I felt that I should check the solution to make sure I hadn’t cheated! It turns out that I had, after all gotten it correct.
