How are the random numbers generated?

We use the browser Math.random() function, which produces a uniformly distributed random number. Every number is equally likely.

Can I draw a lottery row?

Yes! Select the "Unique numbers" mode, set the range to 1-40 and the number count to 7. You get seven different numbers, just like in the Finnish Lotto.

What does "Unique numbers" mean?

In the unique numbers mode every value is different, like in a lottery or a draw, where the same number cannot appear twice.

Can I draw unique numbers without repeats?

Yes. Select the "unique" mode so the same number does not repeat, which suits a lottery row or a draw. In normal mode the numbers can repeat.

How the calculator works and what it’s for▾

How a number is drawn

You set a lower and an upper bound, and the generator picks a number between them so that every option is equally likely. You can also request several numbers at once when you need, for example, multiple winners.

Each draw is independent of the others, so the previous result does not steer the next.

What the generator is used for

Typical uses include contest draws, random ordering, brainstorming lottery rows and research sampling. It is also handy in teaching to illustrate probability.

You can use it instead of physical raffle tickets or dice whenever you want a fast, repeatable way to draw.
