I don't know if I'm misunderstanding this game or it's bugged, but my opponent will bid something like "at least four 4s" and I'll challenge it. The dice are revealed and I'll only have one 4 and my opponent has one 4, making that a total of two 4s. But then it says I've lost the challenge and lose a die. I have screenshots of it, but I'm not sure how to add on mobile.

Do higher pip dice count towards the four 4s or is it ONLY 4s that should be counting towards this?

Are there any 1s on the table?

There were two 1s so that makes perfect sense, thank you so much for clearing this up for me!!
