Begin the game by placing the black hole card at the center of the board. Circle the black hole with an arrangement of face-up cards. Transfer cards to the black hole by clicking on a card that is one value higher or the previous in sequence than the current top card of the black hole. Keep going this sequence until all cards are cleared to the black hole or no more moves are possible. Employ the undo button to correct your last move if needed. Win the game by removing all cards to the black hole. Challenge yourself by attempting to complete the game in as few moves as possible.
