How can this take an hour to play?
I saw another post that mentioned another (German?) edition that removed the six colors end-game trigger. I've played this many times and even when we reach the end of the deck it rarely goes more than 30 minutes.
Is there something to the new edition that I'm missing?
We play multiple rounds/hands. When at least 1 player reaches 100 points that's the end of the game. Of course, that's just us and it can be tweaked to any groups preference ...
