Take a triple number in cash 4 here is a list from Oregon  find 7797  we will split it.

take double 7s mirror one 7 and subtract 2 from the other  you get 25 now put the number back together 2597 make 4 triads out of it  257x 259x, 579x, and 297x one of these will come usually pretty fast  9657 hit 3 draws later 

next example 1117  split take double 1s mirror 6 minus 2  is 9  new pair 69 now add the 17 pair to get 6917  triads 691x, 697x, 917x, and 617x 

3 draws later 7967 hit 

hint if I split the number and the same digit appears that is in the other pair I don't use this triple
