Try to get rid of all your cards before the computer does. Drag one card at a time from your hand at the bottom of the screen to one of the two discard piles in the middle of the screen. The value of the card you drag must be one greater or one less than the card you drop it on. The cards' suits do no matter.
You hold five cards in your hand at a time. Once you get rid of a card you must click your "next card" pile to the left of your hand. if the computer gets stuck, the "flip it" card will appear. Click it to put new cards on the two discard piles. Remember the name of the game is "Speed" so move quickly.
