Overview

Japan’s Lotto 6 draws six numbers from 1–43 twice weekly (Tuesday and Friday). This generator creates as many 6-number lines as you request, using strategies like Random, Odd/Even Balance, Hot/Cold Analysis, Fixed Numbers, or Unique Sets.

Explanation & Methodology

Random: Picks six unique numbers (1–43) at uniform random.
Odd-Even Balance: Attempts to balance odd vs. even count (e.g., 3 odd, 3 even).
Fixed Numbers: You specify up to six numbers; the tool fills any remaining slots randomly.
Hot/Cold Analysis: Biases selection toward historically “hot” or “cold” numbers observed in past draws.
Unique Sets: Ensures each generated 6-number combination is distinct across multiple lines.

Example Generation

To generate 3 lines using “Odd/Even Balance,” click “Generate Numbers.”
Example output:

  • Line 1: 02, 11, 16, 23, 29, 36
  • Line 2: 04, 13, 18, 25, 30, 39
  • Line 3: 01, 10, 15, 22, 28, 35

Explanation: Each line shows six main numbers (1–43) balanced odd/even.

Frequently Asked Questions

How many numbers per line?

Each Japan Lotto 6 line consists of six numbers from 1 to 43.

Can I generate multiple lines at once?

Yes. Enter how many lines you want. If “Ensure Unique 6-Number Sets” is checked, every line will be unique.

What does “Hot/Cold Analysis” mean?

“Hot” numbers appear frequently in past draws; “cold” numbers appear less often. The tool biases selections toward those sets for variety but does not affect actual odds.

What if I fix more than six numbers?

Only the first six valid fixed numbers (1–43) are used; extras are ignored.

Does Lotto 6 have a bonus ball?

No—Japan Lotto 6 only draws six main numbers. This generator does not include a separate bonus ball.
