TV Bingo offers the opportunity to organize a very attractive as well as an interactive show. For example, the direct contact with players during the live broadcast can be organized as well as some additional draws based on phone calls. All aspects are monitored by the computer control system which allows the organizer to check each person who calls the studio. Before a player can participate in one of the games, it is easy to check to make sure the player's ticket is valid for the current round.
