Creating a US States Map puzzle game

Hello,

I would like to create a game which will display a US map with the states shown (or hidden). The player will drag and drop the states to their correct location on the map. When the state is dragged somewhere near the correct location the game will snap it there, otherwise warn the user.

Is there a tutorial for such a puzzle game?

Thanks

I have attached a really simple demo of how to achieve this if you require anything else let me know.

Thanks dhillyard, that was helpful..
