4-person tournament

If there are 2 people left at the end... shouldn't there be a button to put cards down...?

It would be better to have a "stop moving" button that you can't move anymore, and if everyone in the game (except the killer) presses it, you wouldn't have to wait that long.

there is, you leave the game and the whole polka

That's where they decide who gets 1 point and who gets 0 points - exciting, isn't it?
