k216 Awhile back David created a video where he showed that 0-1-2-3 will hit over 70% on the time. If you bet on certain states you will do well. Martingale comes into play when you lose you double your bet and so on until you get it back. David never gets into martingale but its a good method to get your money back if you bet carefully.
Lottodds releases draw alerts twice a day and it gives you various things you can follow. Doubles, Sums, Trinity etc. I find betting against doubles hits a lot. Say for example NJ has 3 straight doubles that come out. Odds are a LWD (0123) single will hit next.
This video is from July 2018. It goes thru win after win and is still valid today. Its such simple filter and creates a lot of consistent wins.
Now you can play the other way too and bet doubles for a higher return. 22 will get you 75. But you have to wait until they hit. The average is 6 wins per month. Depending on the state.
