It's a very easy system which allows you to play 9 numbers on only 3 boards. Of course, we always aim at 6 good numbers, but if only 4 numbers of the winning
combination are among 9 numbers which you chose, you are sure to have at least twice 3 good numbers of it. And even with 3 well grouped together
numbers, you are sure to have twice 3 good numbers of it. The board below serves you as guide to place well your numbers and obtain 3
combinations. You can print it with the example.
