JAMKADIUM Casual Game Jam is Arkadium’s first-ever external game jam. For 25 years, Arkadium has created browser-based casual games enjoyed by millions of players worldwide. Now, we’re looking to expand our portfolio and connect with game developers across the greater New York City area. Whether you’re a first-time jammer or a seasoned developer, we invite you to join us the weekend of October 23 and help shape the future of casual games.

Want to participate in person?

JAMKADIUM Casual Game Jam is a hybrid event, meaning that jammers may join us in-person. In-person participation will take place at the NYU Game Center in Downtown Brooklyn, and will include free food, free swag, a design workshop, and a keynote address given by Arkadium’s CEO, Kenny Rosenblatt.

Due to limited space, in-person participation will require RSVP here: RSVP to JAMKADIUM In-person

Whether you are joining us in-person, or logging on from home, the JAMKADIUM discord will serve as the communication hub for this jam. Joining will give you the opportunity to find teammates, ask questions, and collaborate with the rest of the jammers.

Winners of the game jam will receive cash prizes, and winning games may have the opportunity to be featured on Arkadium’s website. A panel of judges will determine the final placements using the defined scoring criteria.

1st Place: $1,000

2nd Place: $500

3rd Place: $250

We are looking for games that fit into Arkadium’s existing portfolio, which means games that are casual, browser-based, and fun. Games should be playable with a keyboard and mouse and include no offensive content.
