Steam Engine Jigsaw

Recreate this picture of a steam engine putting together its jigsaw puzzle form! There are two modes of play. You can do it timed and for points or just put it together leisurely. You get points for every correct piece and lose points for pieces placed incorrectly. Every minute of play reduces your score, as does clicking the show picture button. Your final total can be added to a high score table if you wish. Have a most excellent time playing Steam Engine Jigsaw!
