1. Definition
“Sequential Numbers” refers to a method of purchasing lottery tickets where the ticket numbers are arranged in consecutive numerical order. This is typically done in fixed sets—such as 10 or 30 tickets—where each ticket’s number increases by one from the previous.
2. Background and Structure
In major Japanese lotteries like Jumbo Takarakuji, each ticket is assigned a group number and a 6-digit serial number. When you purchase sequential tickets, the serial numbers are continuous (e.g., 123456, 123457, 123458…), making it possible to win both the grand prize and the adjacent prizes (known as “before” and “after” prizes).
This purchase method is popular among those specifically aiming for the full prize combination: main prize + adjacent prizes.
3. Examples and Usage
- When buying 30 sequential tickets for the Year-End Jumbo Lottery, you may receive tickets numbered consecutively from, say, 123450 to 123479.
- At a physical lottery booth, clerks may ask, “Would you like Barazume (random) or Renban (sequential)?” Choosing sequential increases your chance at adjacent prizes.
- Online platforms also offer a “sequential” purchase option.
4. Differences from Related Terms
- Random (Barazume): A set of tickets with non-consecutive, mixed numbers and groups—provides broad coverage but no adjacent prize potential
- Sequential: Consecutive ticket numbers, often within the same group, enabling eligibility for adjacent prizes
- Bundle Purchase: A mixed set, sometimes combining sequential and random tickets (e.g., 10 random + 20 sequential)
5. Tips and Considerations
- Sequential numbers are ideal for those targeting the top prize and its adjacent bonuses
- Less suitable for those who want number diversity across the lottery pool
- Useful for groups who want to share tickets evenly and ensure continuity

8. Summary
Sequential Numbers is a lottery purchase method offering consecutive ticket numbers, often chosen by players hoping to win not only the grand prize but also adjacent prizes. While it increases the potential payout in certain scenarios, it reduces number diversity. Players should choose their purchase format based on their prize goals and risk preferences.
