Frequently asked questions
What is Dupla Sena?
It is a number lottery where you pick 6 numbers from 1 to 50. Each ticket competes in TWO back-to-back draws — hence the name "Dupla". You can win in the 1st draw, the 2nd, or both.
How many numbers do I pick?
Exactly 6 numbers, from 1 to 50, no repeats. Use "Quick Pick" for a random selection.
How do I win?
By matching 3, 4, 5 or 6 of your numbers in either of the two draws. 3 hits = Terno, 4 = Quadra, 5 = Quina, 6 = Sena. Each draw pays independently and the prizes add up.
What is the difference between Instant and Official Draw?
In Instant the draw happens immediately, using our verifiable cryptographic RNG. In the Official Draw your bet competes against the real Caixa Econômica Federal result (Mon/Wed/Fri at 9PM BRT).
Can I trust the instant draw?
Yes. Every instant draw is "provably-fair": generated with HMAC-SHA256 from a seed committed by its hash before the draw. You can recompute and audit any draw on the Verify page.
Is this real money?
No. Dupla Sena is 100% entertainment with fictional credits (FUN). There are no deposits, withdrawals or real money (R$) at any point. Nothing here has monetary value.
Do I need to register?
For Instant mode you can play in DEMO without registering. For the Official Draw you need an account, so we can notify the result and credit the FUN prize.
