+
+The player has to move the colored balls around the game board, gathering them
+into the lines of the same color by five.  Once the line is complete it is
+removed from the board, therefore freeing precious space.  In the same time
+the new balls keep arriving by three after each move, filling up the game
+board.
+
+KLines is a single-player game where the player removes colored balls from the
+board by arranging them into lines of five or more.  However, every time the
+player moves a ball, three more balls are added to the board.
