Hi Shawn i am currently working on complex keys with the double hits for example Texas played the 997 at midday the complex keys to put on your hot list would be from double right digit skip middle and keep the far left digit,in this case the results would be 664 and 331,I love the singles,this is how i make my Hot list and play my favorites,I also do cent plays where you use a 1 dollar bill every time your state or state you play get a number with a 0 for instance a 340 hit,convert this number into cents 34 cents and 43 cents -1.00 =66 and 57 now put your 0 in the front or back to make your pick3 play,hope this helps,goodluck
