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.
Point Salad has been a big hit and I’ll back up what others have said about Bohnanza.
I’m tempted to recommend Cat in the Box as a new take on trick taking but I haven’t had the chance to introduce it to non boardgamers yet. It’s a very cool concept but the abstraction of suits could be a bit much for some folks.
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.
