Snap to Grid

Hi,
I have a chess/card game where you move cards across squares on a chessboard. I want the cards to snap to the grid, and also sense when they jump over another card of the opposite type, like in checkers. I saw firemaplegames' demo "Dragging/Snapping," but my computer says GameSalad doesn't support .game files. Is this true, or should I open it in GameSalad anyway?
Any solutions for either question are welcome. Thanks!
