Lotto 6/45 (South Korea) Number Generator, Odds & Free Demo

What is Lotto 6/45 (South Korea)?

Lotto 6/45 is South Korea’s national lottery, commonly called simply ‘Lotto’ or ‘Bok-gwon’, and is drawn every Saturday evening on national television. Players pick six numbers from 1 to 45, and a bonus number drawn from the same pool decides the second prize. A ticket costs ₩1,000 per game, and the jackpot is shared among all winners, so a popular combination can be split many ways. The odds of the top prize are about one in 8.1 million.

How Lotto 6/45 (South Korea) works

1. Pick six different numbers from 1–45 – your own favourites or a random Quick Pick.
2. Check your line once the numbers are drawn – only which numbers match counts, not their order.
3. The top prize needs all six main numbers; smaller combinations win lower prizes set by the operator.

Your chances in Lotto 6/45 (South Korea)

The draw can produce 8,145,060 different results, which means the jackpot odds for one line are 1 in 8,145,060. Lower down the table the picture changes quickly: a result of five main numbers turns up about once in 34,808 lines, and at least three correct main numbers about once in 42 lines.

In Asia, Loto 6 (Japan) (1 in 6.1 million) has better odds and Megalotto 6/45 (1 in 8.1 million) has exactly the same odds. Compared with US Powerball, the jackpot is about 36 times easier to hit. Among the 88 lotteries on this site, Lotto 6/45 (South Korea) ranks number 19 for jackpot odds, where number 1 is the easiest.

Playing two lines in two draws every week – 208 lines a year – you would wait on average around 39,159 years for one jackpot, so the jackpot is something to dream about rather than plan for.

Using the Lotto 6/45 (South Korea) tools on this page

The number generator gives you up to ten Lotto 6/45 (South Korea) lines in the exact format of the game, using your browser’s cryptographic random generator. The odds tab lists every match combination, and the demo lets you pick numbers and watch a simulated draw. In the demo you tap six numbers on a 45-ball board, or let Quick Pick do it.

The simulator goes further: ten years of two lines twice a week means 2,080 lines, and on average about 47 of them would match exactly three main numbers while the chance of a top prize in that time is only about 1 in 3,916. Random numbers do not change your chances, but they do avoid the dates and patterns thousands of other players choose, which matters when a jackpot is shared.
