How is "lucky" decided?

It is not. The tool draws uniformly at random from your range using a cryptographic RNG. "Lucky" is just a friendly name — every number is equally likely on every draw.

What is the difference between Unique and non-unique mode?

In Unique mode no number repeats inside one draw — useful for lottery-style picks. In non-unique mode each pull is independent, so the same number can appear more than once.

Can I use this for the lottery?

You can use it to pick numbers for fun, but every lottery draw is independent and these picks are not "more likely" to win than any other set. Play responsibly.

What range can I pick?

Any integer range where the maximum is larger than the minimum. The count must be between 1 and 100, and (if Unique is on) cannot exceed the size of the range.

Where is the bonus number drawn from?

When Unique is on and there are numbers left over after your main pick, the bonus is drawn from those leftovers. Otherwise it is drawn from the full range.

About this lucky number generator

The lucky number generator draws random integers from a range you control using crypto.getRandomValues with rejection sampling, so every number in the range is equally likely and there is no modulo bias. You can pick whether the draw allows repeats or must be unique, and you can add a single bonus number drawn separately — handy for lottery games that use a "bonus ball" or "powerball" mechanic.

When the Unique option is on, the tool shuffles the full range and takes the first N values, then sorts them in ascending order. With Unique off, each draw is independent so repeats are possible. The bonus number, when enabled, is drawn from the remaining numbers (not in your main set) where possible, which matches how most national lotteries handle their extra ball.

For example, with min 1, max 49, count 6, Unique on, and Add bonus number on, you might get 4, 17, 23, 28, 31, 42 plus a bonus of 9 — exactly the shape of a UK Lotto pick. The tool is meant for entertainment and quick decisions; lottery outcomes are independent of any generator.
