Bluff seems to be broken. My opponents current bid is two fours, there are no fours at all, but I still loose a die. It's not happening all the time though. But as soon as I loose one die, I'll loose the rest, no matter if the bid is correct or not.

Oh dear, I'm so embarrassed right now. I guess I didn`t understand the rules. I forgot the wilds. Sorry, please close.
