System and procedure in the card game bridge (Fig. 2) using virtual message cards. A virtual bridge message box is designed and constructed in a database. Data about bridge games is collected and registered from all reporting boxes during a reporting round. Messages that are submitted through the usual use of the message cards from physical message boxes are registered in the database, including through the use of pattern recognition. When making illegal messages, a technical signal is sent from the database's control system to the players at the table with the option of correction. The control system in the software platform's database uses a "digital twin" of a reporting box, so that 1 virtual reporting box in the database is updated from all 4 physical reporting boxes. Relevant information and instructions from the control system are presented to the people at the table by means of a graphical user interface on a technical device which has access to the control system in the software platform via computer.
