Am I holding it wrong?

I am trying to move a game from iTunes on my mac by dragging its icon for the one game to the left to where the slide out drawer is for my iDevice and when I do it syncs... however it syncs 60+ games at once. My iPhone doesnt have that much space. How do I only have it sync just that one game?

I could download it on to my phone directly but this is driving me crazy.
