The object to this is pickingone or two digits one may feel will hit in ILL: 0,1,2,4,5,6, or 7.Based on this concept, the combination are listed below. There are 21 single combos with 6 doubles in each string. Doubles can be filtered out. You can also filter out the last 5 or 6 recent hits from the single combos to reduce the number of singles and hope repeaters don't hit from those removed. Works better when full string is intact.
