A Game Jam is a short event where you and others work together to create a small game. Most Jams have some kind of restriction on theme or style to get you thinking about games in a new way. Game Jams are a great way to test ideas, build on your skills, and meet other awesome creative people. Do them. Future you will thank you for it. Pirate Software runs Game Jams two times a year and all of our jams have prizes!
The judging team will vote on four major categories for each entry in the Jam. As games are subjective media these categories are guidelines for judges to follow when exploring your game. Don't worry about tricking the judges into liking your game. Use these criteria as loose guidelines to make the best game possible. Don't overthink it.
