You are an awesome ghost hunter. You pop those suckers like balloons and you do it for fun. It is set up like a match three game. You never want to pop one by itself because you will be penalized for it. As you get rid of ghosts you will get jewels for them and you will collect them by letting them drop to the bottom. When you get enough jewels you will get help from a ghost to get rid a majority of your ghost bubbles. Each level is timed and each level has a different set of goals that you must complete in order to move on to the next level.
