You're right, only free once.I think just once for free daily, then it's 10 iron, then 20 iron, then 40 iron, etc until the next day's list goes up.
I'm pretty sure that's right, but I guess I could be wrong. I re-roll once a day even if I complete each challenge just to get a new task for more stars.
Best to save up your re-rolls that cost Iron for Saturday's though when it's now double stars.
