Korean lottery prizes up to ₩2,000,000 are tax-free. Above that, 22% withholding applies up to ₩300,000,000, and 33% on the portion beyond (income tax plus local income tax).

Frequently Asked Questions
Q. Are the numbers really random?
A. Yes. Every line is drawn fresh with the browser's cryptographic random number generator (crypto.getRandomValues); past draws and "hot" numbers play no part.
Q. Do the odd/even or sum options improve my odds?
A. No. Every 6-number combination has the same 1 in 8,145,060 chance of winning first prize. The filters only narrow which lines you get: about 79% of all combinations add up to 100–175, and about 33% have three odd and three even numbers.
Q. Can I use it for my country's lottery?
A. It's built for South Korea's Lotto 6/45 only. Games with other formats (such as 6 from 49, or 5 numbers plus a bonus ball) aren't supported, and the latest results, prize tiers and tax figures on the page are all Korean.
Q. Where do the latest winning numbers come from?
A. They are the most recent Korean Lotto 6/45 draw, held by Dong-Haeng Lottery every Saturday evening (Korea time). The card shows the round, date, six winning numbers and the bonus number.
