This game is a contribution to "Connect the dots" games, I love to play in magazines in my childhood. You are connecting dots in the game to balance the graph and see the resulted shapes from connecting dots.
How to play:
Your aim is to connect the nodes of the graph so all nodes have value of zero. To connect nodes just draw a line (using mouse) from first node to the second node. To delete link between nodes, Just draw line the cut through the link.
