Jam in a Jiffy is a lighthearted 12 hour game jam where the challenge is to take an idea from nothing to a finished playable game in a single day. It is all about speed, creativity, and having fun with whatever you can get working before the deadline. There is no pressure to make a polished masterpiece. The focus is on finishing something small, weird, or experimental and sharing it with others.

Anyone can join regardless of skill level. You can work alone or team up with friends. Any game engine, tool, or style is allowed as long as you can complete your project within the 12 hour window. This is the perfect chance to try a new concept, test a silly idea, or learn something new without worrying about long term commitment.

The jam is meant to be fast paced and collaborative. Talk with other participants, share your progress, and have fun with the short time limit. At the end everyone will be able to play each other’s creations and see the wide variety of games that can come from the same small window of time.
