My oponent has 3 dice: 4, 4, 2 I have 4 dice: 1, 1, 2, 6 My oponent bids "at least four 4s" I challenge it and I lose

How did I lose if he has 3 dice and only two 4s?

EDIT: Nevermind I just read the explanation of the rules on the Subeta Wiki and it seems the bids are made from both of our dice, not just each using our own. I wish the rules on the site were better explained, but I guess that's solved. Please lock.
