Dia de Sorte Number Generator

Dia de Sorte, a Caixa lottery from Brazil, uses a 1-to-31 grid on purpose: it mimics the days of the month, so nearly everyone plays birthdays. If you want out of that pattern, this generator builds the whole bet: 7 to 15 unique numbers plus a lucky month drawn from the 12. Pick how many numbers you want, click, copy. The suggestion comes out ready for the lottery shop or the Caixa app.

The official draw picks 7 numbers and 1 month, and matching only the month pays a fixed prize even if every number misses. The parity filter hides a small arithmetic trap: between 1 and 31 there are only 15 even numbers. Ask for 15 'even only' numbers and you will get the exact same game every time, all 15 evens that exist. With odd numbers the ceiling is 16, so there is still some variation. In every case, the month is drawn independently of the numbers.

Playing more numbers gets expensive fast: a 15-number bet equals 6,435 simple 7-number games, and the price scales accordingly, so check the cost before committing. The draw runs entirely in your browser; nothing is sent to a server and nothing is stored, so copy the result before closing the page. And remember that this tool does not register bets anywhere. It only suggests them.
