Overview
- Bets can be placed until 20:00 (Brasília) on December 31 through lotéricas, the Loterias Caixa website and app, or Caixa Internet Banking, with the drawing set for 22:00.
- The top prize will be distributed on draw night because the special contest does not accumulate, moving to five-number and then four-number winners if no one hits all six.
- A simple bet costs R$ 6, selecting six numbers, while marking up to 20 numbers can reach R$ 232,560; the chance of a simple bet winning the sena is 1 in 50,063,860.
- Official group bets (bolões) have a minimum price of R$ 18, allow 2 to 100 shares with each share at least R$ 7, permit up to 10 bets per bolão, and lotéricas may charge a service fee of up to 35%.
- Retail demand is rising nationwide, with lotéricas reporting brisk sales and growing bolões, including a Maceió group that expanded to 145 participants.
