How to play

A nonogram is a cell based picture puzzle, where you must find all of the shaded cells. If you find all of the shaded cells then you will reveal the hidden picture!

The numbers above and to the left of the grid describe the number of consecutive shaded cells in the row or column. For example, if we imagine a 10x10 grid and we have a ( 10 ) above the first column, then we know that all ten cells are shaded for that column. If in the first row we have the clue ( 5  4 ) this tells us that there are five shaded cells, a gap of at least one non shaded cell, and then four shaded cells.

See below for a small example on a 6x6 grid. We see that the shaded cells reveal a smiley face!

PicoCross took most of a week to create. I have had experience creating projects in Unity before, but this was my first attempt at something for the Pico 8. I am very happy with how this turned out and would love to receive some feedback, even if critical.

This was my first attempt at creating music and sound effects for a game and I am quite happy with the result. It took a good part of a day to get the music right. It is simple, but a jam!

Recently I have gotten into the handheld emulator community and really enjoyed playing Picross on the original GameBoy. It was really fun making an inspired game for the Pico.

Updates to v1.2

  • Added 10 new levels!
  • Fixed a bug where saved progress was not presenting correctly when loading from start.

Thank you everyone for all the feedback!

Fantastic little picross implementation.  Great job!


So Nice! I like it. Nice coding and sound!

Thank you very much :) I was really happy with the music even though it is super super simple.


This is a great implementation of Picross! Thank you for adding a button to mark empty spaces. I had fun solving level 20, with no misses! :D

That is awesome. Level 20 took me quite a while to get right. Had to test it probably about 10 times but could never remember the solution haha. Thank you very much for the comment, I really appreciate it :)


Fun game that I enjoyed greatly, but for some reason level 11 won't mark as completed. I have beaten 15 levels so far and this is the only one causing issues.


Update: completing level 16 marked level 11 as complete, but not level 16

Thank you very much for bringing this up. I will look into it ASAP!

I've finished all of the levels, the only issues I noticed were 11 and 17 not marking themselves complete, and level 16 marking level 11 complete instead of itself. Nonetheless, good job

Many thanks again for letting me know, I have added and update to fix that screen for the future. :)

To calculate the Y coordinate of the level select screen to turn the box green I was using:

Round_down(level_number / 6) 

That only works for the numbers 1-10. The correct equation is:


Many thanks again, really appreciate the feedback!
