Sandboxels
by Zellior
Sandboxels is a falling-sand minigame in which players draw pixels of over 500 elements onto a canvas and watch them interact.
What it does
Players place pixels with the mouse: a left click draws, a right click erases, and a middle click picks an element. Holding shift draws a straight line or intensifies heat, cool and shock effects, and scrolling changes the cursor size. Space pauses the simulation, and the M key opens chat.
Each pixel carries its own properties, such as temperature, so an element can melt, freeze, ignite or break depending on what touches it. Powders fall and liquids flow according to their behavior, and reactions produce fire, density shifts and many other scenarios. Heat simulation and electricity are among the mechanics, and the mod works as a chemistry toy for experiments, cooking or passing time. Single-player saves can be exported and shared with other players.
The mod runs on the client alone, with no server installation. It is published for Fabric only, across five release versions: 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2. The latest Fabric file is 26.2-1.0, and the code is not open source. Source code and an issue tracker are linked publicly, and the mod is still in early beta, so some lag is possible.
Key features
Over 500 elements
Elements include powders, liquids, gases and living materials, each sorted into categories for browsing.
Pixel-level properties
Each pixel stores its own temperature and state, so the same element can behave differently under heat or shock.
Drawing controls
Mouse clicks, shift modifiers and the scroll wheel set drawing, erasing, line tools and brush size.
Save export and import
Single-player canvases can be exported as save files, then shared with and loaded by other players.
Pause and observe
The simulation can be paused with the space bar, letting players inspect reactions before continuing.

Use cases
Passive experimentation
Players learn how elements interact by watching reactions, without any goal to complete.
Idle time
Some players leave the simulation running as a way to pass time while doing something else.
Who it’s for: The mod suits players who want a sandbox for experimenting with chemistry, heat and falling-sand behavior, not a progression-based game.
