Hi ekem6078!
Start here: https://www.lotterypost.com/vtracs The LP Vtracs home page.
You can get there from the blue menu bar at the top right of the LP site. Explore it!
What you do is look at the page above and look at a set of drawn digits and substitute. One Vtrac number represents two different drawn numbers. E.G. for the drawn digit 7 from a Pick 3 drawing you would see the Vtrac equivalent on the far left of the chart (Vtrac for 7 = v3).
Search is your good friend here at LP so try it out and you can read some threads on the topic.
I’ll give you one that is often looked at and was a recap of older threads: https://www.lotterypost.com/topic/205270
It’s a topic that took me a while to get my head wrapped around, so be patient with yourself. Best way I know is to sit down and do some conversions by hand to get the basics. Don't forget to use the favorites feature to save threads, posts and members in your own library. The favorite button is in the upper right corner of the post. One more thing to explore are the many blogs by members with lots of good info.
