It's a 4 person, team based game that involves solving trivial puzzles. You can choose to join a random team or create your own private one. Time per game is about 5 minutes, but depends on the team.
If you say join team it puts you into a random team. If you create your own team it creates a private game and gives you a url to share with 3 other people.
I'm going to take a break for now... but(!), 3 hours remain until I go to bed.
It takes a few moments to load the page:

If anyone wants to set a time so we can play later on, I'd be interested. I'm pretty much always around.
