They say the West Coast is the best coast, 

but which city's game will bring fame to their name?

IGDA LA, 

in collaboration with IGDA SF, IGDA Silicon Valley, & IGDA San Diego, 


proudly invites you to participate in...

...the first! 

Annual! 

California! 

Clash!!!! 

The Clash is a California-wide, head-to-head competition hosted by the California chapters of the International Game Developer's Association (IGDA).  Each year, we'll battle it out to determine which chapter takes home the championship title and...the CHAMPIONSHIP BELT! 

We're inviting YOU to join us and represent your region - secure bragging rights for your slice of California!

While this jam has a competitive element, it's friendly in nature and is about trying new things, pushing your limits, and making the greatest game you can.
