It's not viable long term.

ROI per amount of wins;

0 Winners x -100%
1 Winner x -100%
2 Winners x -81%
3 Winners x -44%
4 Winners x +12%
5 Winners x +87%
6 Winners x +181%

Unless you regularly hit 5 or 6 wins, that's 83%+ then you're heading to brokesville. You might get lucky a few times and cash big but everytime you hit 50% instead of 67% you lose big. If you have one day where you go 3/6, you'll have to go on a streak of 4/6 just to get back to where you were.
