I play a lot of the classic games on Cardgames.io. Spades in particular is a favorite, albeit I also really enjoy an Icelandic game called “Manni”.
My family played a lot of what I later learned to be a variation of Shanghai rum, a contract rummy played with three 52 card decks. It takes a while to get over a full game, but it was always a good time.
I personally am a fan of jet-lagged, the game. Sam, Ben, and Adam from wendover productions/Half as interesting compete in various travel-based games across the world.
