Tickets for next year's World Cup went on sale online on Tuesday with 16 of the 64 games drawing a high number of applicants, including the opening match in Sao Paulo and the final in Rio de Janeiro.

FIFA's website shows there are more ticket applicants than the number of seats available in all four price categories for the opener and the final at Maracana Stadium. That means the chances of securing a ticket will depend on a random selection draw conducted by soccer's governing body in October.

The other matches had a high demand for tickets only in the cheapest category, available to Brazilians.

Tickets sales began at 6 a.m. EDT and applications quickly poured in. The FIFA website says there was a virtual queue "due to an exceedingly high demand for access to the ticketing page."
