 All boulders are replaced by letters so they can be referred to. Moving the boulders is shortened to '''r''' for right, '''l''' for left, '''u''' for up, '''d''' for down. An asterisk is used to denote the last move filled a hole (and thus removed the boulder from the game). So '''N ddrr*''' means move boulder '''N''' two times down and two times to the right into a hole.
