宝くじシミュレーター - 一番運のいいひと決定戦

This is a simulator that lets you buy any number of tickets for a massive lottery with a maximum prize of 700 million yen, using the same probabilities as the real thing.

"If I bought a lot, what prize would I win?"

Test your luck with a simulation based on real probability data.

■ Realistic Winning Probabilities

━━━━━━━━━━━━━━━━━━━━━━━━━━━━
A complete reproduction of the finite pool system with 20 million tickets per unit.

1st prize: 700 million yen (1 ticket), adjacent prizes: 150 million yen (2 tickets), 2nd prize: 100 million yen (1 ticket),

3rd prize: 10 million yen (4 tickets)... All based on the actual number of winning tickets.

*Probability design conforms to the publicly available specifications of the 2025 year-end Jumbo Lottery.

Because it's a finite pool system, if you buy 20 million tickets, you are guaranteed to win the 1st prize.

However, the investment is 6 billion yen. With your luck, how many tickets would it take to win?

■ Two Modes
━━━━━━━━━━━━━━━━━━━━━━━━━━━━


[Simulator Mode]

Buy tickets one at a time, 10 at a time, 100 at a time, 1,000 at a time, 10,000 at a time...

You can keep buying tickets at your preferred speed.

Keep spinning until you hit the grand prize and test your luck!

When you win the grand prize, a "Your Luck" rating will be displayed.

55 humorous comments will tell you how lucky you are.


Examples:

・Winning with less than 20,000 tickets → "The same probability as a meteorite falling on your house. Cosmic-scale luck."

・Winning with 10 million tickets → "The same probability as getting heads in a coin toss. THE average."

・18 million or more tickets → "Of course you'll win if you buy them all. Brute force. I respect that."
