Quina Number Generator

Quina has one of the widest ranges among Brazil's federal lotteries: 1 to 80. Pick by hand and you will probably lean on birthdays, which stop at 31 and leave 49 numbers untouched. This generator draws 5 to 15 numbers across the full range, with no repeats, sorted in ascending order. You can restrict it to even or odd numbers if that is how you like to play, and copy the result in one click to take to a lottery agency or Caixa's app.

The tool shuffles all 80 numbers with a Fisher-Yates shuffle and takes the first few off the pile, so every number is equally likely. The detail most sites skip is what extra numbers cost: a ticket is priced by the 5-number combinations it contains. Playing 6 numbers equals 6 simple bets, 7 equals 21, and the maximum of 15 equals 3,003. The price scales in that proportion, so it pays to do the math before filling the slip.

Do not expect the generator to change your odds: with 5 numbers, hitting the quina is a 1 in 24,040,016 shot no matter who picked them. What it does is spread your bet across all 80 numbers and steer you away from popular combinations, which split the prize when they win. The even and odd filters work here, since there are 40 of each, but restricting half the board changes nothing statistically. Everything runs in your browser; no numbers are sent to a server.
