The game has several skill levels, which control how the security robot responds. On beginner level the security robot can be seen on the player's map, making it relatively easy to avoid, whereas at higher levels it is invisible. Operating the elevator will trigger it to approach the player's robot in beginner, while at higher levels operating any control will make it move. On the Advanced level the user must continually move in order to avoid it. The player has three probes (lives) to complete the game, and loses if all three are destroyed or time runs out.
