XTRIS is a simple arcade game that will test your dexterity. This level editor allows you to create your very own XTRIS levels!


Use the mouse to click on squares and change their function. 

  • A dark grey square indicates that it will not be present in the level.
  • A white square indicates that it will be part of the level.
  • A green flag square indicates that it will be part of the level AND will be where the player first spawns.

You must have EXACTLY ONE green square for the level to load.

How it works

Lexaloffle has provided a version of PICO-8 that runs in the browser, called PICO-8 Education Edition. You can find it here: https://www.pico-8-edu.com/. This version of PICO-8 has the ability to load code and sprites from an encoded HTML string. By carefully manipulating the URL string while editing the level, we can send construct an HTML link that will exactly load the game's code AND level layout. This "game" was made with vanilla HTML and Javascript, and a little help from Bootstrap 5.

wow, I would like to know how you edit the links (like making games in links instead of coding them in the IDE), and how do you know what part is the code for the level?

Hey there! I’d be happy to share my code and explain the process, but it’d be easier to communicate on Discord. Shoot me a friend request (Fletch#9817) and I’d be happy to answer your question!
