I wouldn't say almost flawlessly. I've consistently had issues with Jackbox. Usually midway through the game someone doesn't receive the answers screen and is forced to sit out for the rest of the game.

Why they don't reserve your session based on a cookie or something like that is completely beyond me. Hell, even the phone going to sleep in most cases is enough to bump you out of the game.

+1 for Jackbox Party Games. I have all 3 on my XBone and 1 & 2 on my laptop (and Drawful 2 on both as well). It's a fun game as long as it's all setup and ready to go.
