The Gold Dragon is really challenging to put together as are any of the elongated puzzles that are available but they are nice when put together. I didn't really have to much trouble building it as I have built this Dragon about 18 times already . I have 2 each of all of the other 8 colors that they make of this dragon so it wasn't to hard for me to build it. It is challenging but when it is done it is a really nice piece to look at and display.
