Number Groups

Numbers belong to the same group if their first digit is the same. Thus to illustrate fully:

Single digit number group:
1, 2, 3, 4, 5, 6, 7, 8, 9

Teen number group:
10, 11, 12, 13, 14, 15, 16, 17, 18, 19

Twenty-something number group:
20, 21, 22, 23, 24, 25, 26, 27, 28, 29

Thirty-something number group:
30, 31, 32, 33, 34, 35, 36, 37, 38, 39

Forty-something number group:
40, 41, 42

What's the rule with number groups? It simply states that the winning lotto result will unlikely have five or six numbers that belong to the same number group. This means that you have to spread your bets to at least three number groups to have a greater chance at winning.
