Once it has grabbed something it will reel it up. Heavy objects like rocks and large pieces of gold will be harder to reel up. Grab bags contain random amounts of money, a strength power-up, or a stick of dynamite. Between levels you can buy items that can help you.
Collect the target amount of money by the end of the level. If you dont meet your goal by the end of the level its game over. Your money carries over from one level to the next.
If you accidentally blow up everything on a level or you just feel like going on, you can press the "Exit Level" button. If you havent met your level goal it will be game over.
