Limitless Worlds: The Anitya World Jam

Reality has rules. Your world does not have to.
From 9 September to 14 October we are running Limitless Worlds, the Anitya World Jam. Five weeks, a cash challenge every week, and one theme: a place that shouldn't exist.
A staircase that never ends. A bedroom at the bottom of the ocean, dry, with fish outside the window. Any genre, any tone, as long as your world is pushing boundaries. A limitless world.
Two rules. If it does not push your limits, you are not done yet. If no one wants to play it again, you are not done either.
Prizes
| Prize | Amount |
|---|---|
| Overall winner | 1,000 USD |
| Second | 750 USD |
| Third | 300 USD |
| Each weekly challenge | 100 USD |
| Surprise cash prizes | During the jam |
Every prize is judged by a person. The best worlds also lead the Anitya feed, where every new visitor lands.
The five weeks
Week one is a warm-up: no brief, just build. After that, a new challenge every week, each worth 100 USD. Enter one week or all of them.
| Week | Dates | What runs |
|---|---|---|
| 1 | 9 to 15 Sep | Warm-up, no brief |
| 2 | 16 to 22 Sep | Challenge 1 |
| 3 | 23 to 29 Sep | Challenge 2 |
| 4 | 30 Sep to 6 Oct | Challenge 3 |
| 5 | 7 to 13 Oct | Challenge 4 |
| Close | 14 Oct | Entries close |
Every challenge stays sealed until the day it unlocks, so nobody gets a head start.
How to enter
- Join the Anitya Discord. Challenges drop there, and it is where you get help.
- Publish your world to the public feed in Anitya.
- Share it in the World Jam submissions channel: title, link, a screenshot or two.
Enter any time before 14 October. Submit as many worlds as you like, and keep editing them until entries close.
How we judge
Judges play your world. Three things carry the score.
| What we score | Weight | What it means |
|---|---|---|
| Immersive | 60% | Does it get people hooked? |
| Creative | 20% | Are you using Anitya's features in a creative way? |
| Inviting | 20% | How likely are people to get curious about the world and open it? (tip: the world's name and thumbnail are a good place to start!) |
Most of the score is the thing that is hard to fake: whether people stay. We do not judge imported asset quality, size, length or difficulty.
The rules
- Free to enter. You must be 16 or over to receive a cash prize.
- Build it during the jam. Worlds published before 9 September are not eligible.
- Imported assets are welcome, GLB files from Blender import directly, and you must own the rights to anything you bring in.
- Your world must be published to the public feed. It stays yours, and the link works for anyone, account or not.
- Submitting someone else's world removes you from the jam.
New to Anitya?
That is what the warm-up week is for. Describe a world, get a rough playable draft in minutes, then shape it yourself. It runs in your browser, no code and no downloads, and the people you share it with never need an account.
We are in open beta, so some of it is rough. Push your limits and help us push ours.

Everything happens in the Discord: questions, submissions, weekly challenges and help when you get stuck.
