I am playing a group of optimized combinations instead of wheels; I am not playing neither a matrix of all numbers.
The combinations (24):
04 08 14 19 26 27…01 02 14 19 28 30…09 10 11 14 28 31…02 09 12 23 30 31
35 39 40 45 48 49…01 09 19 31 39 48…12 19 30 34 40 49…19 25 27 28 40 45
06 12 18 20 36 49…01 10 14 25 40 48…04 07 10 27 38 42…04 09 14 25 30 34
03 05 11 17 47 49…09 12 14 27 39 45…08 11 25 27 34 39…02 08 23 25 48 49
08 10 27 28 35 48…02 04 26 28 35 45…02 10 26 31 40 49…09 11 26 34 40 48
04 10 19 23 39 40…02 14 23 26 34 39…02 04 11 19 31 34…10 12 14 26 30 35
The final total price is $24.
