I build a march based upon playing lines.
Pick any three alternating lines, like 246 or 134 or 532 or any other combination.
Then you follow the wheel playing does three lines.
If you lose then you add the last hitting line and play 4 lines to break even.
You only lose if you get 5 alternating lines.
it's a pretty cool idea and i have not test it so much.
Would also work playing 4 lines and recoup playing 5 lines preventing all 6 to show.
Dozen play.
