Rio 2016 organisers are urging sports fans to order tickets for the Games by April 30 in order to guarantee participation in the second draw for tickets in July.
Ordering now also means buyers can pay in up to five interest-free installments.
Ticket ordering has been in phases, with the first random draw phase starting on March 31. After the draw has been made, everyone will receive an email with the results announced no later than June 2015.
Only those who applied for the first draw will be eligible for the second random draw. With the same requirements as before, this second draw will favour customers that were not previously selected. It will be necessary to submit a new request on the Rio 2016 ticket website. Results will be sent by email in August 2015.
Online sales will begin in October 2015 and tickets will be sold on a first-come, first-served basis. During the Games, all remaining tickets will also be on sale at box offices.
There will be half-price entrance to all sessions for Brazilian residents over 60 years old and wheelchair users (with attendants) valid for all price categories of any session; Students, teachers (municipal public schools of Rio de Janeiro only), people with additional accessibility requirements, people with reduced mobility, and obese people; valid only for the most affordable category in all sessions.
The most expensive tickets for horse sport fans will be to the individual and team showjumping finals on August 17 and 19, which will cost up to 540 Brazilian Reals ($US178, $NZ234).
Organisers are also issuing special souvenir tickets with a commemorative design.
