Amongst my Ohio-based relatves, there's a card game that's been passed down through the generations. It was pronounced "HA-ZI", but we had no idea how it was actually spelled. So, as a little in-joke, we'd spell it any way that could concievably be pronounced the correct way. It's a four-player game, with two teams of two people. The rules are a little complicated, but if you're a card player, it's similar to Double-Bid Euchre. For XMas 2012, I spent the two months prior developing a digital version of our family game so that we could play remotely, or against/with an AI. I wasn't able to get it finished in time, though, and online play was never finished, so it has languished since. Also, after extensive searching, I found the rules published under the name "Haus". It's a little disappointing that the game didn't solely belong to my family, but it's still one of my favorite games of all time.
This version has an AI that will follow the rules, and can be played by 1-4 humans in hotseat mode. Unfortunately, there isn't any tutorial at the moment, so if you don't know how to play, it's going to be difficult to understand!
