A rendition of the Climate/Warming Stripes for Picotron, using exactly 1024 bytes of compressed code, for #Pico1k Jam 2026.
The climate stripes were created by Professor Ed Hawkins at the University of Reading in 2018. They show clearly and vividly how global average temperatures have risen over nearly two centuries.

this is a very simple implementation of the classic 3d spinning cube, written based on a simple logic I used for my pixelart simulation render python script. since it's the same python logic rewritten in pico-8, it's not the most optimal nor the fastest way to render a 3d cube, this is supposed to be easy to read and understand how these calculations work.

can you find the win condition?
inspired by the pico-8 sorting demo
and a "for loop" practice that
became this short game

Slime Time
Slime Time is my attempt in making a game in week for "The Very Serious Juniper Dev Game Jam." I'm sure like everyone else who has participated in this Jam, I had a ton of ideas and tweaks that I cut for the sake of time. The beginning of this Jam was extremely challenging for me to hone in on a simple idea and execute it well. My idea is basically slime whack-a-mole with a surprise spin mechanic (since the theme for this Jam is "Spin to Win"). This was an interesting challenge that revealed to me what I think I do well concerning game development and where I'm most certainly weak. I have no idea how this will be received, but overall I had a fun time with this Game Jam especially when the game started to come together.

Alien Sneak
Alien Sneak is my submission for the PICO-1K Jam 2026 and this was a tough one. I'm still getting familiar with Pico-8, but thought this would be a good jam to hone in on the coding aspect of Pico-8. My idea was create a sneaking game with objects moving in a set path, and the player character has to get around them. The player character is an alien trying to dodge spotlights. I tried to create a tense atmosphere with rain particles and suspenseful music (hopefully the music is not too annoying). The set paths were taking up too much space, so I ended up randomizing the paths and increasing the speed of each spotlight as the player character advances in levels.

A little rally driving game for the PICO-1K jam.
Race the clock down a windy country road. Reach the checkpoints to extend your time.
How far can you get before the time runs out?

This is my little entry to this year's Falling Block Jam. It's been a while since I made something in Pico-8, it's so fun!
Hungry chompers are hungry!
Arrow keys: Move blocks
Z/X keys: Rotate blocks
When a chomper has a path of at least 3 food blocks, they will EAT and then DISAPPEAR. Paths must be contiguous with no gaps or backtracking.
Longer paths are worth more points.
If a chomper can EAT directly after the grid settles from a previous chomper EATING, it triggers a combo. combos also increase score.
... That's pretty much it, it's a simple idea, but I think it turned out pretty fun, with some surprising strategies based on the simple rules.

This program lets users run a background python script that connects to Picotron via TCP socket. It is specially made for setups where you boot or auto-login into Picotron, just add the .py file to your startup, and you're good to go. NOTE: Currently interactive terminal applications are not supported, because the script
Setup
For Picotron, just unsandbox the cart and run it, it will install the latest version to /appdata/system/util Then just run picoterm in the terminal to connect. NOTE: The TCP socket is ONLY exposed to the machine itself, so be sure to run the script on the same machine as Picotron, if you would like to change this open the python script and change HOST = '127.0.0.1' to HOST = '0.0.0.0' Here is the python code (NOTE: This only works on MacOS and Linux, if you would like to make a windows version please feel free) NOTE: This program need the pexpect module, make sure you have that installed

hihi
would anyone be interested in an r/place big drawing sorta thing on here?
ideas been thrown around quite a little and thinking i might just set one up if enough people are interested (and also would make it viewable externally too, e.g: picotron_paint.astralsparv.cc/vid1.png or an online webview that updates, or both?
Would want to make different boards for each vid() mode, then you can use it for the full 480x270, and the other planned video modes (would just black bar it on the sides until all the vid()s are actually added.).
Would make it possible as a wallpaper cart too hopefully, shouldn't be hard. Would be neat to be able to connect it to my at home server display to have it just update randomly as people draw

SAM-Robot is a tiny speech synthesizer built for PICO-8. Inspired by the classic SAM voice system, it can turn English text into real-time robotic speech. The project combines text-to-phoneme conversion, formant synthesis and sampled consonants, while being optimized to fit PICO-8’s limited CPU, memory and cartridge space.

This is the version 2 of a game that I made before this that was called fishing.
controls
❎-exit title screen
⬇️-cast
⬆️-reel in
🅾️-shop
⬆️/⬇️-scroll
❎-buy item
🅾️exit shop
rules
test your clicking skills with this cool fishing simulator, and start buying upgrades to be the bigger fish to fry!
behind the scenes
I am very young, and this game took a lot of time to figure out. one of the pros was making the clouds, fish, and other scenery, because I really like to do art in the pico 8 style. one of the cons though, was how long it took to make this whole thing. It took about an hour to get the casting to work, and even more for the shop. nonetheless, I hope you enjoy this fun fishing game that I have spent so long on.

Made during Falling Block Jam 2026!
Controls:
Up - Hard drop
Left - Move left
Right - Move right
Down - Soft drop (Hard drop on Master★)
Z / C - Rotate (Counter-clockwise by default)
X / V - Rotate (Clockwise by default)
Rotation direction can be swapped in the pause menu at any time.
Screenshake effects can be toggled on/off at anytime in the pause menu.
To complete a puzzle you must fill in the pattern with bright tiles, without filling the board completely (excluding gutter) and without topping out.
Place tiles you don't want in the gutter. It will remove a determined amount of rows every few drops. The gutter is the three right-most columns, colour-coded purple.

Find 9 cats lost in a cave...
For the PICO-1K Jam 2026. 1024 compressed bytes exactly! 🐈 (As per the 1k jam rules the game does not use the spritesheet/map; it's 100% code.)
Instructions
Arrow keys to move, O to jump. Green walls are bouncy and sticky. Find 9 cats and feel satisfied (there's no game over screen).
Sprite & Map Compression
The only real feature of note folks might be interested in is the sprite compression which uses a basic RLE system.
sprite_string = ""
last_pixel = 0
last_runlength = 0
for idx = 0, 128 * 8 do
current_pixel = sget(idx % 128, idx \ 128)
if (current_pixel != last_pixel and last_runlength > 0) or last_runlength == 15 then

Recently on picotron's discord server we've been talking about making a "pass the game" game, I don't know the correct term, but the core idea is that there's 5 people, each person gets an hour to work on the game but they can't communicate.
We also had an idea to take a spin on it, for the first three itterations it would be like any other, however the 4'th and 5'th iteration would split into two "different" games both building off of what the first three people made, to see where the idea would go.
As stated previously, the biggest rule is that you can't directly communicate
What this means, is that for example, you are allowed to leave a comment explaining what a function does, and you can leave a comment saying what has already been made, but you can't leave a comment saying what needs to be added to a function or what you want to do later on
As of now I believe we have 5 people (including me) who would participate, so we need 2 more people, the order in which what people develop the game when will be random, however please say if you are fine with going first, not stating so will automatically leave to the assumption that you don't wish to do so.

I started this 3D renderer, but stopped working on it since my game concept was a bit performance-demanding and hard to design levels for. I may return after a Picotron update. Sharing in case anyone else benefits from the code.
Three demos are included. Press Heart (F) to switch demo.
Orthographic Platformer:
- Move with left stick (arrow keys)
- Camera with right stick (WSAD)
- Jump with X (X)
3D Scenes (boxes and sphere):
- Move camera with left stick + O/X (arrows + Z/X)
- Rotate camera with right stick and L/R (WSAD + QE)
Features:
- Quads
- Backface culling
- Sprite textures
- Ambient + diffuse lighting with dither patterns
!!!WARNING!!! if you run in Picotron, it can crash Picotron itself if objects too close to camera. Save your work before using in Picotron!

In pico-8 0.2.7, toggling fullscreen with Alt-Enter (actually option-enter) doesn't work for me. Note that I'm running the raspberry pi 64-bit build on Asahi Linux on a Macbook Pro. It works fine otherwise
