Dragging one card at a time, re-arrange the edge cards in descending order to dig out the face-down cards.  Suit colour doesn't matter in Casual mode, but you must alternate red-black on Regular and Expert!

Deal more cards onto the waste as you need them.  On Casual and Expert you deal 3 at a time, on Regular you only deal 1.

Cards will automatically get sucked into the black hole once you no longer need them, or you can throw them there yourself to make space.

Send all 8 suits into the black hole to win the round!  Clear the screen in the fastest time to get a higher score bonus!
