Create a new prototype game that could be the next big thing!

Join up with game developers of all experience levels and prototype a game!

Alpha Game Jam is about sharing a tight deadline with friends to help motivate to build something new.

There is no strict rules on what (or how) to build your game. Use this as your opportunity to try something you haven’t done before, prototype out that experiment, or simply to have some fun.

Everybody is welcome! Come alone or with friends. Bring an idea, or create one on the spot. Meet new teammates, or have your team all ready to go.

Created by the Independent Game Developers of Silicon Valley Meetup group, hosted at Microsoft’s San Francisco campus.

Together, let’s help each other to finish that alpha version and create the next big game for all to enjoy!

NOTE: Not an overnight event. We jamming until midnight each night, returning at 10am the next morning. We will have at least two free meals, more if we can secure more sponsors.
