The 5th annual PICO-8 1K Jam (#Pico1k) has now started! 🥳
🌐 https://itch.io/jam/pico-1k-2025

You have until the end of September to make cool things in PICO-8 (or Picotron)
...by using only 1K (1024) Compressed Bytes of code 🗜️

No using of built-in Gfx, Map or Sound data (or external files)
ALL content must be created using code submitted.

It can be a:
🕹️ Game
🎞️ Demo (Animated or Interactive)
🛠️ Tool or Utility
...whatever you can fit within 1KB, basically!

It's a relaxed, non-competitive jam, running for a whole month.

Please refer to the PICO-1K 2025 Jam page for Rules, FAQ & Resources & more info.

Yaaay, let's go! Can't wait to see what kind of demoscene wizardry people pull out of the hat this year.

> No using of built-in Gfx, Map or Sound data

I don't understand this rule. Does this mean we can't use the sound and gfx editor in pico-8?

That's correct, @zangman.
All Gfx, Map, SFX or Music needs to be generated by code that totals <= 1024 KB.
For example, instead of drawing sprites in editor - you use drawing functions in code (e.g. CIRCFILL, LINE, etc).

The simplest check is: if you copy your source code (only) and paste it into a completely new instance of PICO-8, does your cart still run as expected?
Hope this helps 🤓

@zangman,

You can use the built-in editors to create your art and music assets, but the data can't be stored in the spritesheet or sound memory, it needs to be converted to string, table, or command form and included as part of your code.
