betmgm slot challenge says eligible bets only but doesnt say min stake anywhere.

I jumped on this slot challenge promo and it says something about “eligible bets only” but doesn’t list a minimum stake anywhere that I can find. Been combing through the promo page, the FAQ, even the fine print at the bottom - nothing. Makes me think I could just run a bunch of minimum spins and qualify, but my gut says that’s too easy and they’ll pull some gotcha after the fact. Last time there was a slot race like this, I got burned because a spin had to be at least a buck, but they only told folks who asked support about it. Shady, if you ask me.

Anyone here actually run minimum bets and get their rewards no problem? Or did you find out too late there was some mystery threshold? I’m always weighing it out between risk and value, but this one’s just confusing. How low can you go before it doesn’t count?
