FAQ

Are the numbers truly random?

Yes. Each number is generated using JavaScript's Math.random() function, providing a pseudo-random selection with no bias. However, like any random generator, this does not predict or improve your chances of winning.

What is the bonus number?

In Korean Lotto 6/45, a bonus number is drawn separately after the 6 main numbers. It's used to determine 2nd prize winners — those who match 5 of the 6 main numbers plus the bonus number.

Can I exclude certain numbers?

Yes! Use the Exclude filter to click on numbers you want to remove from the pool. You can also use the quick-exclude buttons to exclude entire ranges (e.g., all numbers from 1-10).

Can I force certain numbers to appear?

Yes. Switch to the 'Must Include' filter mode and click up to 6 numbers that will always appear in your generated results.

Does this improve my chances of winning?

No. Every combination of 6 numbers from 1-45 has exactly the same probability of being drawn. This tool simply provides a convenient way to pick random numbers instead of choosing them yourself.

How much does Korean Lotto cost?

A single Korean Lotto 6/45 game costs ₩1,000 (about $0.75 USD). You can buy up to 5 games on one ticket at any convenience store or online through the Dong Hang Lottery website.
