Since the core of the initial observation is a 7 draw window, it would be the easiest yet.

With the pick 3 it would be super cheap. 0.50 bets on both mid day and evening draws for a total expense of $7

Since the pick 3 and pick 5 have a similar window, but the pick 5 has no 0.50 option, that cost would be $14 per week.

To play both would be $21 for a week.

However, I have a general idea of indicators highlighting when NOT to play (narrow neutral spread)... this could make it even cheaper.

Of course, the goal was to have the pick 3 pay for the rest, so between 0, $3.50 or $7 per week until a hit (straight play only).

The plan is also to increase the pick 3 to $1 while on their money. Also to take a profit from any hit rather than recycling all back into the games. On a $250 straight pick 3 hit... pocketing $150 would leave enough to play the 3s and 5s at $1 for 3 weeks AND be able to get another 2 weeks back at $7

So of course the overall design is one of cheapness.

The jackpot games are a distant target, but that strategy will involve one line over whatever the window works out to be... so still super cheap, and also restricted to play on "house" money.

Will probably fail like all others, but it is the cheapest one yet!

This time I will track hits and count the number of times I had to pony up the $7 for each week over a yet to be determined test window. Perhaps I look at expense over 10 weeks and then if out of pocket was $70, then yet another system can be abandoned to the scrap heap.
