Bits and Pieces Wine Bottle with Stand – 3D Wooden Jigsaw Puzzle (difficulty 6 of 10) is a great display puzzle and comes with a rack to hold it. When assembled, it is approximately 10 1/2 X 2 1/2 inches. It is made of wood and is basically a 13 piece, 3-D puzzle. As far as difficulty, anything over 1 out of 5 would be an exaggeration. It is very simple to take apart and if you line up the pieces from top to bottom, the only way it comes apart is when you simply reverse the order in re-assembling it. If you mix up the pieces, it is still as simple as all you have to do is to start with the largest at the bottom and by choosing next largest pieces, complete the bottle from bottom to top. The only slight challenge is when you slide the pieces together, if they don’t fit, slide the opposite way. This couldn’t be simpler. I suppose you could try to make it a bit more of a challenge by taking apart then reassembling it in the dark or behind your back. For the amount you pay for this puzzle the enjoyment or challenge for your buck is very small. To add to my disappointment, one of the pieces broke when dropped.
