• the game software can e.g. be entered into the host computer via a conventional DVD or CD-ROM. As best seen in figures 4a the game will display a suggested structure for the player to build, which in order to form a general view is a tower structure 12.
• the software is designed to display a number of different structures all of which can be build using the same building elements and when one structure is correctly completed the next structure will be displayed. The player can of course choose a different structure depending on skills and motivation or design personal structures to be built.
• the player will then start building the structure 12 by placing the building elements 1 on the master unit 2. As seen in figure 4a - 4d the player will continue to add building elements 1 to the master unit 2 until the assembled structure 12' is completed in fig. 4d.
• the player When the structure 12' is completed the player will receive information in form of a signal that the assembled structure 12' is correct.
• the signal can be in any given relevant form, e.g. a light and/or sound signal. If the structure 12' had not been assembled correctly the game system according to the invention would send a signal that the structure was incorrect, and preferably also information of which building elements were incorrectly placed or had an incorrect three- dimensional orientation in the final structure 12.
• the master unit 2 will apply small alternating currents during the game, to some or all of the building elements 1, thereby activating the light emitting diodes 8, the sensors 9 and the microcontrollers (not shown). These components will start to communicate as described above under figure 3, not only with the interconnected building elements 1 but also with a microcontroller in the master unit 2.
• the verification means in e.g. the master unit can either process the received data continuously or wait until the system is stabilized, i.e. no new data is added, before the data is processed.
• the player will receive relevant desired information on the building process, e.g. the time spend from start to finish, if the building process could be optimized by using the building elements in a different order, if the structure is correctly assembles and/or where possible errors are located in the structure and how to correct these errors.

• the game board itself can comprise a display unit and hardware/software for the relevant game however the game board can within the scope of the present invention also be a simple master unit, which is connected to a host computer via a universal serial bus (USB) .
• USB universal serial bus
• the game system comprises a number of hardware devices, such as the building elements, master unit and/or host computer. These devices are capable of exchanging data in any suitable form e.g. in the form of data package or other similar form of communication relevant information between two physical entities.
• data packages are well known to a person skilled in the art and will therefore not be discussed in details, however one possible solution is to provide a data package comprises three fields.
• the first field is an opcode, which specifies the type and the purpose of the package as well as the format of the following Payload field.
• the Payload field contains data associated with the opcode command.
• the last field is the CHK field that contains a checksum number used to detect if the package was transmitted and received correctly.
• the master unit will periodically run a protocol instance of the applied software, starting with locating the first building element in the three-dimensional structure e.g. by sending a beacon into the structure.
• the protocol instance ends when the master unit has extracted all data from the building elements and said data is ready for further processing.
• the behavior of each device during one protocol instance is described by a finite state machine, also well known to a person skilled in the art.
