I start the play with a matrix done in sixteen optimized combinations.

The combinations (16):

03 05 11 17 47 49…08 14 15 21 28 39…01 10 25 31 42 49…01 09 15 30 45 49
01 12 23 24 41 46…02 32 33 40 44 49…06 12 14 33 35 49…08 10 19 20 33 34
06 12 18 20 36 49…04 07 10 27 38 42…09 15 18 19 31 39…05 21 22 29 36 47
05 22 28 33 34 47…01 16 25 37 43 48…10 11 12 30 31 42…01 07 09 13 26 45

The final total price is $16. Babar
