The object is to get rid of all the cards in your hand. The cards you are allowed to play must match the number, color, or be in sequence with the top card in the discard pile. When someone plays a "Terrible 10" or "Card Attack" card, someone will be pushing the button on the Card Attack machine. It is unpredictable: you may push the button a number of times and it won't fire, or it might fire after one push. If it fires, it shoots cards at you and won't stop until you push the button again. The cards go into your hand and play carries on this way until one person is out of cards. The person with the lowest score at the end of a predetermined number of rounds is the winner.
