Welcome to the Butterfly Effect Jam!
Every participant begins with the exact same sentence.
Your challenge is simple:
Change exactly ONE thing in that sentence, then create a game inspired by the new meaning.
One word.
One punctuation mark.
One number.
One tiny edit.
Note: Usage of "" and () are considered as one change.
Just like the butterfly effect, even the smallest change can lead to a completely different outcome.
By the end of the jam, we'll have dozens of games that all started from the same sentence—but evolved into entirely unique experiences.
The goblin insisted he was just a very short dragon.
The original sentence will be revealed when the jam begins.
You may make one modification to the sentence.
For example:
Replace one word
Add one word
Remove one word
Change one number
Change one name
Change punctuation
Rearrange the order of words
The goal isn't to find loopholes—it's to explore how one tiny change can completely transform an idea.
Your game should be based on your edited version of the sentence.
Interpret it however you like. Be literal, abstract, funny, emotional, or completely unexpected.
Include the following in your submission:
This lets everyone see how the same starting point branched into countless different ideas.
This jam is designed exclusively for solo developers.
The goal is to celebrate individual creativity and discover how differently each participant interprets the exact same starting point.
Don't try to build your dream game.
This jam celebrates small, (un)polished experiences.
A game that lasts around 5–15 minutes is much more valuable than a huge unfinished project.
Focus on one idea.
Execute it well.
Finish it.
Any game engine is welcome.
Pre-made assets and AI-generated assets are allowed.
Please disclose any external assets or AI-generated content on your submission page.
Leave constructive feedback, encourage other participants, and remember that everyone is here to learn and have fun.
The Butterfly Effect Jam is an experiment in creativity.
One sentence. One change. Countless possibilities.
We can't wait to see where your butterfly effect takes you.
Keep it simple.
Finish your game.
Play other people's creations.
