The goal of the game is to get as much money as possible. To do this you select a level and choose a card. Each column has a unique rule in selecting which card to give you based on which card you choose and how you choose it. The levels to the left are the most self-explanatory where the levels to the right may seem more random. Greater difficulty simply increases the number of cards to choose from. All the levels have a constant way of giving you cards, none of them randomly select the card.
