The goal of each player is to finalize the cards from his deck (at the sides of central deck, the computer on the left and the player on the right).
To do this, the player draws 5 cards from the central deck and with them will have to create the sequence of cards starting from ace until the number preceding the card of his deck and then be able to remove.
These sequences are created on the left side of the screen, the cards are placed regardless of the color or suit.
Finished his turn, when you are not able to remove the card from own deck, the player discards a card on one of the 4 columns available, always regardless of the color or suit. Such cards may be used at any time by retrieving them in the order in which they are placed.
