Drag all your cards to the pile in the middle before the computer does. The up arrow indicate a superior number, the down arrow indicate a inferior number. The red cards change the sense of the arrows.
Spend a nice time playing solitaire. You have to click two identical cards, that will be the base of the game, to get rid of them. You can see the cards that are turned to get new ones till you're done with all of them. Use your mouse.
