As already mentioned the game should award 40 points for a bingo. If you've experienced otherwise I'd like to hear about it, because that would be a bug. Send an email to firstname.lastname@example.org with details about the game (your and your opponent's username should be sufficient), and I'll take a look.

Hm, I play van and bag all the time. I just checked and the other words you mention are also in the word list.
