I will try again my system of pairs and small wheel very suitable for small budget.
1 wheel of group pairs with 18 numbers, 12 combinations, and 4 out of 4 guaranteed if 2 pairs are guessed correctly.
The pairs:
06 45
16 23
04 39
10 34
11 28
24 40
01 46
13 27
07 30
1 wheel of 10 numbers, 8 combinations, and 4 out of 5 guaranteed.
The numbers: 03 05 08 14 20 21 22 31 36 42
The total cost is $10.
