I am using sixteen combinations optimized, to create a matrix of all forty nine numbers played.
The combinations (16):
04 07 10 27 38 42…10 11 12 31 42 48…08 15 21 28 34 39…01 09 13 19 26 45
02 06 16 27 28 49…08 12 30 31 35 48…01 07 12 20 33 48…14 22 29 37 41 46
03 05 11 17 47 49…06 12 18 20 36 49…01 23 25 32 40 44…12 19 24 31 43 46
04 09 15 19 25 26…04 21 22 29 43 47…04 09 21 30 33 43…04 08 09 16 33 47
The final total price is $16.
