I keep an excel file of over 1200 drawings that shows what position each number has played. I break the numbers down into groups of decades; 1-9 are singles; 10-19 are teens, and so on. Each decade plays most often in a particular position; singles mostly in the first position naturally, and so on. I play $1 each drawing. Same numbers every night. Why? Because most of the time only 2 numbers will come in and I still win $2. More importantly, the jackpot is not very impressive. Usually only about 25k, and many times it will be split among winners. I have experimented with wheels, and playing several lines, but in my opinion, like the other games, the more you spend, the more you lose, over time. The jackpot just isn't worth spending more than a buck.
I really wish Tx would bring in a game like Pa's Quinto, which is a pick 5 game, like pick 3 or pick 4. The odds are 100,000 to one, and a straight payout is 50k. Very good odds for 50k.
