The Powder Toy game works by providing users with virtual materials to use in order to simulate physics experiments. These virtual materials include liquids, gases and electronic components. The game can also simulate air pressure and velocity, gravity, heat and chemical interactions.
Users can simulate almost anything having to do with physics, including bombs, guns, terrains and complex machines. Users can virtually operate machines and blow things up. Users must register for an account in order to play the game. Registration involves providing a user name, email address and password. The game is free to play.
Users can also connect with each other on the Powder Toy website forum. The forum includes areas to discuss creations, discuss creation of scripts, get help with problems, provide feedback and discuss general topics. Users also may discuss development of the game itself and obtain assistance with development. Users can view the most recent topics on the bottom of the forum page.
Users can also browse and play thousands of simulations already constructed by others. The Browse section of the website shows pages of these simulations that users can view and leave comments on. Users can also search for a simulation using the search box.
