Dupla-Sena Number Generator

Dupla-Sena's appeal is that a single ticket enters two draws in the same contest. If you want fresh numbers instead of the same old set, this tool generates two at once: two independent sets of 6 to 15 numbers between 1 and 50, drawn separately and shown in ascending order. The copy button grabs both games together, labeled as first and second draw, ready to paste wherever you keep your bets.

It helps to know what you are looking at. On a real Dupla-Sena ticket you mark one set of numbers, and that same set plays in both draws of the contest — you cannot enter different numbers per draw. The two sets shown here are effectively two ticket suggestions: pick one for your bet, or register both as separate bets. Internally the tool uses a Fisher-Yates shuffle, giving all 50 numbers the same chance of coming up.

With 6 numbers, the odds of a sena are 1 in 15,890,700 per draw, and since each contest runs two draws, the same ticket gets two shots. Extra numbers multiply the cost by the combinations they create: 7 numbers count as 7 simple bets, 15 as 5,005. The generator does not change any probability; it just avoids the birthday bias that ignores numbers from 32 to 50. Everything happens in your browser, with no data sent to a server.
