Los Angeles-based indie developer collective and game space Glitch City will kick off a holiday-themed game jam this Friday, Nov. 29 to raise money for Child's Play Charity, the organization announced.

The Holiday Game Jam will begin on Friday and span the month of December, ending on Dec. 22. On Christmas Day, Dec. 25, all games completed during the jam will be released to raise money for Child's Play. Games will be sold as pay-what-you-want.

The jam's guidelines are to make a game that epitomizes the holiday spirit. "Spread cheer and love during the holidays," reads the rules. "We want games of a positive nature. Gore, hate, and sarcasm need not apply. But if you want to make a Die Hard game, that's cool."

The event is being organized by Hyper Light Drifter developer Teddy Diefenbach and Archie Prakash, creator of Asteroid Soccer 2014. Developers worldwide can participate and work from anywhere during the jam as they build games that "celebrate the optimism, thankfulness, and love of the holiday season." Every day, a new door on the website's holiday calendar will open and feature a new in-progress game.

Donations towards the charity can be made through the jam's official website. Developers interested in participating can sign up through the event's Facebook page
