“Big Quadrox consists of 4 simple burr sticks in a frame. Like the smaller Quadrox, the frame is incomplete meaning that almost everything is visible but the pieces infuriatingly won't come out easily despite such large gaps. The puzzler needs some serious thought and exploration to find their way through the level solution. It needs gravity and a little dexterity to move through it and in retrospect I would have to admit that the solution is really fairly logical. I got completely stuck after 14 moves. I knew what I had to achieve but, for the life of me, I could not seem to find the specific move that would allow the path to continue. After 4 evenings of toil I suddenly found the move and proceeded to take out the first piece. The removal of the next 2 pieces is far from trivial even though you can see inside where all the notches and blocks are. The reassembly is just as much fun. Interestingly, this was less difficult than expected and I had it back together in just 15 minutes with great relief. Subsequent solves found me getting stuck at the 15th move each time. Only after solving it the fifth time could I do it at will. This, to me, makes the Big Quadrox a superb puzzle – one of my favourites of the year so far.”
