Sandboxels — Physics Simulation vs Word Crafting
Sandboxels looks like a game from 2005 at first glance. It is not. Underneath the pixel graphics is a real physics engine with heat transfer, electricity, density, and chemical reactions across over 500 materials. If Infinite Craft is about combining words, Sandboxels is about combining forces. This guide breaks down the difference and shows you where to start.
Short answer: Sandboxels is a falling-sand physics simulation with over 500 materials that react based on heat, density, and chemical rules. Infinite Craft is a word-combining game where you merge text elements. One feels like a laboratory; the other feels like a crossword puzzle that never ends.
🔬 What Sandboxels actually is
You pick an element from the sidebar. You draw it onto a pixel grid. Then you watch what happens. Water flows. Sand falls. Fire spreads. Lava melts through rock. Ice freezes water into more ice. Every material has physical properties — density, temperature, flammability — and they interact accordingly.
What separates it from old falling-sand games is the scope. There are lifeforms that move on their own. There is an electrical system that lets you build working circuits. There is a food and cooking branch that lets you combine ingredients. And there is a modding system that adds entirely new element packs.
500+ elements. One pixel grid. Thousands of reactions.

🎮 Controls you actually need to know
The game has dozens of keyboard shortcuts, but these six cover ninety percent of what you will do.
Place the currently selected element onto the canvas. Hold and drag to paint a continuous stream.
Remove whatever is under the cursor. Useful when a reaction gets out of hand and you need to contain it.
Freezes everything on screen. Use this to set up a scene precisely before letting physics take over.
Selects whatever element is under the cursor. The fastest way to grab an element you forgot the name of.
Hold Shift while using Heat, Cool, or Shock to apply the effect at maximum strength. Melts or freezes things instantly.
Opens a search box. Type the first few letters of any element to jump straight to it in the sidebar.
🧪 Best experiments for first-time players
These four scenes teach you how heat, density, and phase changes work without overwhelming you. Start with the volcano and work outward.
Build a mountain out of Rock. Leave a crater at the top. Fill it with Lava. Then add Water above the crater and unpause.
What happens: Steam, new rock, and a chain reaction that spreads downward. It is the single best way to see density and heat working together.
Plant a row of Trees. Leave a gap. On one side, place a line of Fire. Unpause and watch how the gap determines whether the fire spreads or dies.
What happens: Fire needs fuel and air. Removing one breaks the chain. It teaches you how to contain reactions.
Put Water in a container made of Wall. Add Ice to one side. Then use Heat on the other side.
What happens: The ice melts. The water near the heat turns to Steam. If you cool the steam back down, it becomes water again. Full cycle, no reactions required.
Place two lines of Wire separated by a gap. Put a Battery at one end. Fill the gap with Water.
What happens: Electricity conducts through the water and completes the circuit. This is the foundation for every electricity experiment in the game.
🧩 Mods that change the game
The base game has over 500 elements. Mods add hundreds more. These four are the most popular and the easiest to start with.
