You can use this assessment to place bets with numbers that do not appear in the history.

You can reach the following conclusions:

Consecutive number combinations (e.g., 123456-123457) are extremely rare, with only adjacent prizes showing ±1 differences.

No dominant number range (like 80,000-99,999) exists, but digits are fairly evenly distributed, with some positions favoring digits 1 and 4.

The ticket group (1-99) is far easier to predict than the exact 6-digit number, with a 10,000 times higher probability.

Specific numbers within a group are the hardest to predict.
