Planet Solitaire is a variant solitaire game. But it is more interesting than I have played a long time and do not want to stop. You will be addicted to this game. It is totally different. There are six combinations that two cards could match and then disappear. There are two parts of them, you need to match them all. Every part is important, you should coordinate both. Calculate the cards, do not let them have any card to match. It is really Burns the brain, sometimes it depends on luck too.
