Oh and in the version I have, you're not allowed to discard when all of the clue tokens are available, but it's possible in this online implementation. My version is the old one where you can still tell someone where his 3s are (and point nowhere) if he doesn't have any, so I'm not sure which one has it wrong. I tried to utilize this rule to force my teammate to do something other than discarding, but then he went and discarded the second yellow 3 anyway. Well, it's not like that game was even winnable in the first place, since he also thought that receiving a clue about a 5 early means that you should discard it.
I'm never going to play with randoms again.
EDIT: Opponent, teammate, they're almost the same thing.
