Understand how the Nação Rubro-Negra program draws work
Numbers are chosen by the Federal Lottery and have no direction
By Communication - Flamengo - inOne of the biggest innovations the Nação Rubro-Negra program brought to its fan club members in 2018 was the raffle system. Members of Nação exchange points to participate, and the prizes are varied. Through this system, fan club members have already won all-expenses-paid trips to watch Mengão and autographed jerseys—and the goal is to further increase the number of experiences like this.
The Nação Rubro-Negra program guarantees that the draws are carried out in complete safety and there is NO bias whatsoever - neither in the experiences in exchange for points, nor in the draws.
When a member registers for a lottery, a 5-digit number is randomly generated by Nação's system and is available for consultation by the member themselves. Each ST has a unique number, like a lottery ticket. The winning ticket is drawn by Caixa's Federal Lottery and, therefore, does not involve the Nação team. The winning number is chosen according to the last digit of each draw conducted by the Federal Lottery, as shown in the image below. If there are no STs in Nação's database with the five digits identical to those drawn, the winner is chosen by approximation.

In the example above, the ST with number 51200 would be the winner of the draw.
These numbers are drawn at 19 pm every Wednesday and Saturday of the year, randomly and impartially, and are audited by Caixa Econômica Federal itself. The numbers can be checked whenever they are drawn on the Federal Lottery website.
