Hi, what's up with wild buzzer? It's not working?

It was disabled for two player mode wich makes sense.

Nice guess: buzzers are disabled when only two players remain. I think it's easy enough to understand why it doesn't make sens to have buzzers with two players.

I see you also now can't intercept using a 7. Maybe if you try to play a 7 or wild and can't, you shouldn't get the 3 point penalty?

If you activated the 0/7 rule, yes, you can't intercept with a 7. The reason is simple: with a 7 you can exchange your hand with somebody else. If you play a 7, and somebody intercept you before you make your exchange choice, then you have a problem: in which order should the exchanges be done ? It isn't well defined. Therefore it's easier to completely disable interceptions on 7s.

Right I get that. So if I try to play a 7, I probably shouldn't get the 3 point penalty. Same with wilds.
