By 'the last piece puzzle' do you mean what is usually called the Fifteen Puzzle - where you have 15 numbered tiles in a 4x4 frame and you have to arrange them in order? Most of those sold are insoluble and there is a simple formula for telling you whether they have a solution or not.  But there is no point in my telling you about it until I know that we're talking about the same thing!
