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. This is the second year of the event.

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.

The event will be hosted at the Microsoft Reactor, a new community space at 680 Folsom in San Francisco.

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


NOTE: Not an overnight event. We will be jamming until midnight each night, returning at 10am the next morning.

FOOD NOTE: UPDATE: We will have dinner on Friday, lunch and dinner on Saturday, and lunch on Sunday!
