The start and the finish are crucial to have a successful maze. The finish can have certain requirements, like destroying all icemen, finding all diamonds, or both. Mazes do not require a finish line, but it is extremely helpful when there is one. Many players spend several minute going through a maze only to discover the creator put no finish marker. Though, if the maze does not have a finish line, the menu at the start of the game will display a message saying NOT WINNABLE. CONTACT THE AUTHOR.
