Lotto Number Generator
Korean Lotto 6/45 asks you to match 6 numbers drawn from 1 to 45. Pick how many games you want (1–5) and press the button — the generator draws 6 unique numbers per game at random and sorts them in ascending order. Every combination is equally likely, exactly as in the real draw, and you can regenerate as many times as you like.

Examples
Generate 5 games for a semi-automatic purchase
Set the game count to 5, generate the numbers, and copy them onto a play slip at a lottery retailer. Five games cost ₩5,000 (₩1,000 per game), and unlike the retailer's quick pick you get to see your numbers before buying.
Share numbers with family or coworkers
Generate 3 games and let each person buy one. Screenshot the generated numbers to keep a record of who bought which combination — it makes checking the results much easier.
Mix fixed manual numbers with random picks
Combine 2 games of the numbers you always play with 3 randomly generated games for a total of 5 — a handy way to mix manual and random combinations in one purchase.
FAQ
Are the generated numbers truly random?
The generator uses the browser's built-in Math.random function to draw 6 unique numbers from 1–45. It is a statistically well-distributed pseudo-random generator, which is indistinguishable from true randomness for picking lottery numbers. It is not cryptographic randomness, but no generation method changes your odds of winning.
Is it smarter to play the most frequently drawn numbers?
No. Each Lotto draw is independent, so there is no statistical basis for past 'hot' numbers appearing more often in the future. Frequency charts and 'overdue number' analyses can be fun to look at, but they cannot change your probability of winning.
What are the odds of winning the Lotto 6/45 jackpot?
The probability of matching all 6 numbers out of 45 is 1 in 8,145,060 — roughly 1 in 8.14 million. It is often compared to being struck by lightning, and the odds are identical no matter which combination you choose.
Do quick-pick and manual selection have different odds?
No. Whether a terminal picks the numbers or you do, the draw probability is exactly the same. One caveat: manual picks based on birthdays (1–31) are more likely to overlap with other players, which raises the chance of splitting the jackpot if you do win.
How do I use these numbers to buy an actual ticket?
At a Korean lottery retailer, take a play slip (OMR card) and mark the 6 generated numbers on one line per game, then hand it in — this is a manual (or semi-automatic) purchase. You can also enter the numbers yourself on the official Dhlottery website or app, subject to weekly purchase limits per person.
How Korean Lotto 6/45 works
Korea's Lotto 6/45 draws 6 winning numbers plus 1 bonus number from 1–45. Matching all 6 wins 1st prize; 5 numbers plus the bonus wins 2nd; 5 numbers wins 3rd; 4 numbers wins 4th (₩50,000); and 3 numbers wins 5th (₩5,000).
The jackpot odds are about 1 in 8.14 million (1/8,145,060), 2nd prize about 1 in 1.36 million, and even 5th prize (3 matches) is roughly 1 in 45. The ball colors used here match the official televised draw: yellow for 1–10, blue for 11–20, red for 21–30, gray for 31–40, and green for 41–45.
Playing responsibly
Only about half of Lotto ticket sales are returned as prize money, so the expected value of every ticket is clearly negative. The more and the longer you play, the more you are mathematically guaranteed to lose on average.
Treat the lottery as light entertainment, set a weekly spending cap and stick to it, and only spend money you can afford to lose. Never chase losses by buying more tickets. If gambling ever feels like a problem, seek help from a gambling addiction support service such as Korea's helpline at 1336.
