The game aims to illustrate the performance characteristics of a 20th century Siemens "EMS" programmed telephone. The players are to move their 6 game pieces in turn to target fields by rolling the dice. Before the sixth playing piece may enter a target field, all so-called "contact chips" must be used up. In order to gain certain advantages in the course of the game, the players must collect cards with features of the telephone on predefined fields. These are, for example, the right to enter a target field, to hand over more contact chips, to enter occupied fields, etc. The first player to hand in all contact chips and move their 6th piece to a target field wins the game. —user summary
