+    <p>
+     KLines is a simple but highly addictive one player game.
+    </p>
+    <p>
+     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.
+    </p>
