Abstract: There are described a method and relative system to assign a lottery-awarded good. A message of participation is sent to the lottery through a communication device. A central electronic processor stores information representative of the telephone number of origin of the message of participation received into a database. The processor increases a counter by an amount equal to the amount of participation. The counter indicates an amount representative of an overall current amount of participation. The processor compares the overall amount with a predetermined value made available for purchasing goods belonging to the category of prizes offered. If the overall amount of participation is less than such predetermined value, further messages of participation in the lottery are accepted. If the overall amount of participation is equal to the predetermined value, goods are awarded in that predetermined category of prizes offered.
