I am looking for a simple card game that would be fun for the elderly and at the same time would break the monotony of traditional card games, that they are currently playing. Preferably something internationally popular so it is easy to buy in the EU.
I played Cat in the Box today for the first time, and while I grew up on trick takers, and have nearly all the other mentioned suggestions on this post I just did not like this one. I need to get at least 10-15 plays before I make a final thought on it, but it is in the bottom for me.
