The objective of the game is to collect as many energy stars as possible with your adder, without crashing into the walls, obstacles or the adder's tail. To control the adder use the left and right arrow key. Apart from collecting energy stars you can also collect power ups. These power ups can be either good or bad, you can either take the power up yourself or send it to another player. Press the down arrow key to send the power up to yourself or press the up button to send it to the leader. If you press the escape key the power up will be removed. It is also possible to use the F1 - F4 buttons to send the power up to a specific player.
