About Korean Lotto 6/45
Korean Lotto 6/45 (로또 6/45) is South Korea's most popular lottery game, operated by NANUM LOTTO on behalf of the government under the Korea Lottery Commission. Launched in 2002, it has become a weekly tradition for millions of Koreans seeking a chance at life-changing prizes.
The game is simple: players choose 6 numbers from a pool of 1 to 45. During each Saturday draw, 6 winning numbers plus 1 bonus number are drawn. Prizes are awarded based on how many of your chosen numbers match the drawn numbers. Tickets cost just ₩1,000 (approximately $0.75 USD) each, making it one of the most affordable lotteries in the world.
Revenue from Lotto 6/45 ticket sales is partly directed toward public welfare projects, including education, sports, and social services, making every ticket purchase a contribution to Korean society.

Prize Structure & Odds
Korean Lotto 6/45 offers five prize tiers. The jackpot (1st prize) is pari-mutuel — it grows until a winner is found and is split equally among all 1st prize winners in a single draw.
| Prize Rank | Matching Numbers | Odds of Winning | Prize Amount |
|---|---|---|---|
| 1st Prize (Jackpot) | 6 numbers | 1 in 8,145,060 | Variable (jackpot pool) |
| 2nd Prize | 5 numbers + bonus | 1 in 1,357,510 | Variable (fixed % of pool) |
| 3rd Prize | 5 numbers | 1 in 35,724 | Variable (fixed % of pool) |
| 4th Prize | 4 numbers | 1 in 733 | Fixed ₩50,000 |
| 5th Prize | 3 numbers | 1 in 45 | Fixed ₩5,000 |
* Jackpot pool is determined by total ticket sales minus operating costs. 1st, 2nd, and 3rd prizes are split proportionally among winners in that draw. Odds are approximate.
Tips for Lotto Players
🎲 All Numbers Are Equal
Every number from 1 to 45 has an exactly equal probability of being drawn. There is no such thing as a "lucky" or "due" number in a truly random draw. Our generator ensures every combination has the same chance of winning.
📊 Avoid Popular Patterns
Many players choose numbers based on birthdays (1–31), sequences (1,2,3,4,5,6), or visual patterns on the ticket. While this doesn't affect your odds of winning, it does increase the chance of sharing the prize if you do win. Using a random generator helps avoid these common patterns.
🎫 Play Multiple Lines
Buying multiple tickets with different number combinations is the only mathematically valid way to increase your chances of winning. Each additional ticket adds one more chance at the prize, but remember that the overall odds remain very low.
💰 Set a Budget
Decide in advance how much you are comfortable spending on lottery tickets each week and stick to that limit. The lottery should be treated as entertainment, not an investment strategy. Never spend more than you can afford to lose.
📅 Play Consistently
Some players prefer to use the same set of numbers every week. While this has no mathematical advantage, it ensures you never miss a draw with your chosen numbers. Whether you use the same numbers or generate new ones each time, consistency is a personal preference.
🏆 Claim Prizes Promptly
In Korea, Lotto prizes must be claimed within one year of the draw date. Prizes up to ₩200,000 can be claimed at any authorized retailer. Larger prizes must be claimed at a NANUM LOTTO regional office. Always sign the back of your ticket immediately.
Frequently Asked Questions
Is this number generator truly random?
Yes. This generator uses JavaScript's Math.random() function, which is a pseudorandom number generator (PRNG) based on the Xorshift128+ algorithm in modern browsers. While not cryptographically random, it is statistically random and completely unbiased — every number from 1 to 45 has an equal probability of being selected each time.
When does the Korean Lotto draw take place?
The Korean Lotto 6/45 draw is held every Saturday evening at 8:45 PM Korea Standard Time (KST). Tickets must be purchased before 8:00 PM KST on the day of the draw. Results are published on the official NANUM LOTTO website immediately after the draw.
How is the jackpot amount determined?
The jackpot (1st prize) is funded by a percentage of total ticket sales. Approximately 40% of all ticket revenue goes into the prize pool, and the jackpot receives about 75% of that pool. If no one wins the jackpot in a given week, the prize rolls over and accumulates for the following week, which is why jackpots can sometimes reach several billion won.
Can I play Korean Lotto online?
Yes. Korean residents with a valid ID can purchase Lotto 6/45 tickets through the official NANUM LOTTO online platform (dhlottery.co.kr). International players who are not Korean residents must purchase tickets in person at an authorized retailer when visiting Korea. This website is not affiliated with NANUM LOTTO and does not sell tickets.
Are Lotto winnings taxable in Korea?
Yes. In South Korea, lottery prize winnings are subject to income tax. Prizes up to ₩3 million are taxed at 20%. Prizes between ₩3 million and ₩500 million are taxed at 20% (withholding tax). Prizes exceeding ₩500 million are taxed at 30%. Taxes are automatically withheld when you claim your prize. We recommend consulting a tax professional for specific advice.
What happens if I lose my winning ticket?
A Lotto ticket is a bearer instrument — whoever holds the physical ticket can claim the prize. If you lose your ticket, you generally cannot claim the prize. This is why it is extremely important to sign the back of your ticket immediately upon purchase and store it in a safe place. There is no way to trace a lost ticket back to the original buyer.
Play Responsibly
The lottery is a form of entertainment designed to be fun. It is important to remember that the odds of winning the jackpot are extremely low (1 in 8,145,060). Here are some guidelines for responsible play:
- Only spend money on lottery tickets that you can genuinely afford to lose.
- Do not view the lottery as a reliable source of income or a financial strategy.
- If you feel that gambling is negatively affecting your finances, relationships, or mental health, seek help immediately.
