Abstract: A system for ordering tickets for sporting events that are taking place in a stadium is provided herein. In an early bird stage, a seat allocation function calculates an amount of seats in the stadium for each fan club and offers it as a service order. Parameters of the seat allocation function are constant and variable for each ticket order. A seat allocation is performed for each specified combination of the sporting event of the team that the fan admires versus other teams. The ticket order is provided as a service order to fans who wish to reserve a seat and to pay official price for the ticket in case the team the fan admires will play in the specified sporting event. A ticket is sold in an official price for every ticket service order, and seats for each fan club are being allocated in separate zones of the stadium.
