If you don't use the Arithmetic mechanism and you will always win the game. see the game played by the computer in "Automatic" mode, which always wins. Play using the Arithmetic mechanism by tapping a card, then tap an Operator (+ - * /) then tap another card. a card will be computer and placed in a column if it fits (ie: if it computed to the correct suit and value, where the value is one less than a card in the 7 columns, or one greater that a card in the top 4 cards). If you need a red 7 and you have a red 5 and a red 2 you tap the 5, then the +, then the 2 and the red 7 will be created for you. it's great for practicing simple math.
