The 4 straight numbers on the sheet are the best of a group of 17 straight numbers for Texas. All 17 numbers are on a special sheet I posted HERE. This product has all 520 codes I collected to create the Excel sheet. I will send out an email when one of the 17 numbers hits straight. Only purchase this product if (1) you want the sheet with 17 straight numbers OR (2) you want the 520 codes for Texas. Once you have the codes, you can figure out a lot about the Texas Pick 3 game; best box numbers, best straight numbers, best pairs, best front pairs, best back pairs, etc.
