This system allows you to play 8 numbers on 8 boards. Of course, we always aim at 6 good numbers, but if only 4 numbers of the winning combination
are among 8 numbers which you chose, you are sure to have least 4 good numbers of it. And even with 3 numbers, you are sure to have at least twice
3 good numbers of it. The board below serves you as guide to place well your numbers and obtain 8 combinations. You can print it with the example.
