I'm looking for games to just chill out with, not a specific genre or style, just things that aren't stressful or require complex problem solving. It's easy to just say "casual games" but I'm looking for something a bit more involved than Peggle here.

So, any tips for games to play when you come home after a tiring day and want to just curl up with a blanket on the armchair with a cup of cocoa and relax for a bit?
