Please note that the registration buttons below are to Google Forms, which do not work on certain military networks. If you have trouble accessing the below forms from work, try it on a personal device at home.

REGISTRATION

Registration for Connections 2025 is now OPEN. The form linked below will register you for our three-day unclassified conference running July 29-31. There is an optional classified day for U.S. citizens who hold a SECRET clearance on July 28 – when you use the link to register for the unclassified conference you can indicate your interest in receiving additional information about the classified day, if you are a U.S. citizen with an appropriate clearance.

GAME LAB SIGNUP

The Game Lab is Connections’ small group discussion component, where participants gather (self-select) to explore topics of mutual interest. It has been one of the most productive and well-regarded portions of the conference, but it depends on you, the participants, to define the topics and to lead the conversations. You will meet others with similar interests and have the opportunity to host a wide ranging conversation about something you want to learn more about. These are probably the easiest possible conversations to lead – if there is one thing wargamers like to do, it is talk about wargaming. It is also a great way to get a cross-section of wargaming community opinion on something. Use the button above to submit a topic.

GAME DEMO SIGNUP

Every year the Connections conference features game demonstrations as a way for our participants to showcase games and tools that may be of interest to others. This is a great way to show something you think the rest of the attendees would find of interest, or to gather feedback from a wide variety of wargame practitioners. The Game Demo session will be on July 29. In general, the Game Demo session is about setting up your game, display, or tool for the other participants to circulate among the various tables, see your demo, hear what you have to say, and ask questions, though you may also have time to run some short playthroughs during the Game Demo session or during the evening’s events. Use the button above to sign up if you are interested in bringing a game or other relevant display or tool for our Game Demo session.

You can also use the same button to sign up to bring a game for the Connections Game Night, to be held the evening of Wednesday, July 30. You can sign up to bring the same game to the Game Demo session and the Game Night if you like. The Game Night allows more time for playing through a game you want to share with the community.
