Lottery number generator
Random lines for Powerball, Mega Millions and Millionaire for Life. It will not improve your odds, because nothing can. It will keep you off the combinations thousands of other players are holding, which changes what a win is worth.
Generated in your browser with the operating system’s cryptographic random source, not a seeded pseudo-random one, and nothing is sent anywhere. These lines are exactly as likely to win as any others, including the ones you already play.
What a generator can and cannot do
It cannot help you win. Powerball has 292,201,338 possible tickets and every one of them has the same single chance. A generated line, your birthday, and 1-2-3-4-5 are identical bets.
What it can do is avoid company. A jackpot is divided among everyone holding the winning line, and players do not choose uniformly: dates crowd 1 to 31, tidy shapes crowd the play slip, and published hot-number lists crowd whatever they publish. Six of the 75 Powerball jackpots won since 2015 were split, and the arithmetic of that is set entirely by how ordinary your combination was.
The full argument, with the 2005 draw that produced 110 second-prize winners at once, is in how to pick lottery numbers.
Why the randomness here is different
Almost every generator on the web is built on Math.floor(Math.random() * n). That is biased. The float has a fixed number of possible values, n rarely divides it evenly, and the remainder makes some outcomes marginally likelier than others.
The bias is far too small to matter to anyone’s ticket. It matters here for a different reason: this site spends two guides arguing that every combination is equally likely, and it would be a poor advertisement for that argument to hand out numbers from a generator that disagrees. So this one draws from crypto.getRandomValues and rejects any draw landing in the truncated tail, which removes the bias exactly rather than approximately.
It runs entirely in your browser. Nothing is generated on our server, nothing is stored, and no two visitors receive the same line from a cached page.
Frequently asked questions
Is a lottery number generator better than picking your own numbers?
Neither is better for winning, because every combination has exactly the same probability in every draw. A generator is better at one narrow thing: it has no birthdays and no fondness for patterns, so it is less likely to produce a line that thousands of other people are also holding.
Are generated numbers more likely to win?
No. A generated line and a hand-picked line have identical odds. Anyone claiming a generator improves your chances is wrong, and no arrangement of the numbers 1 to 69 is luckier than another.
Is this generator actually random?
It uses crypto.getRandomValues, the operating system’s cryptographic random source, with rejection sampling to remove modulo bias. Most web generators use Math.random with a modulo, which makes some numbers very slightly likelier than others. The effect is tiny, but a page arguing that all combinations are equal should not ship a generator that quietly disagrees.
What does "avoid combinations lots of people play" do?
It re-draws the line if it lands on a shape large numbers of players pick: all five numbers inside 1 to 31, three or more consecutive numbers, all odd or all even, all multiples of five, or everything bunched into one narrow block. Those lines win exactly as often as any other. They just get shared more when they do.
Does a quick pick from the store differ from this?
Functionally no. A retailer terminal draws a random line the same way. Roughly three-quarters of tickets sold are quick picks, which is why most jackpot winners hold them, and that is a fact about ticket mix rather than about luck.
Should I play the same generated numbers every week?
It makes no difference. Draws are independent, so a line does not become more likely by being played repeatedly, and you do not miss out by changing it. Pick whichever you will find easier to keep track of.
