5Dimes betting contest

So,  I'm at four wins going on five on their streak survivor.  Does a bunch of small,  ten and twelve dollar bets cover my minimum requirement to get the full $50 free play or do I have to make at least one $50 bet?  Thanx for any help here.

do a massive parlay lol

Can't imagine why I'm even worried about it,  it's not like I'm gonna get paid if I do win.

Five now.......no acknowledgement whatsoever.
