Copying my my comment from before: "Your going to have do the casino if you want the money. Just pick the highest option and save before an attempt and load back to the save if you don't get any money back."
That used to work but doesn’t anymore. If you try, you get losing streaks even after loading. I’m in the same boat, there’s no way to get the mil. Had to redo.
Honestly I just held skip and kept clicking the highest option. It does take a few minutes but I think it's overall a net positive (unless I missed an update or something.)
